     Chapter 2.  From Astral Beliefs to Kepler, Fludd and Newton                       

                               ~~~~~~~~~~~~~~~

             

        1.  In the Chinese Commentary on the Chuang Tzu by Kuo Hsiang  (4th century A.D.) we find:  "The principles of things are from the very start correct.  None can escape from them.  Therefore a person is never born by mistake, and what he is born with is never an error.  Although heaven and earth are vast and the myriad things are many, the fact that I happen to be here is not something that spiritual beings of heaven and earth, sages and worthies of the land, and people of supreme strength or perfect knowledge can violate.....  Therefore if we realize that our nature and destiny are what they should be, we will have no anxiety and will be at ease with ourselves in the face of life or death, prominence or obscurity, or an infinite amount of changes and variations, and will be in accord with principle.”  (A Source Book in Chinese Philosophy, 1963, translated and compiled by Wing-Tsit Chan, p. 332.)

        2.  In a charming although perhaps not authoritative book, Peter Lum says:  "The Chinese believed that the world of stars was exactly similar to that of men.  It was perforce a happier land, without flood or famine, but it was subject to the same laws as China, and its immortal inhabitants were very similar to the Chinese.  The familiar world known to mankind, with its obvious imperfections, was rather like a reflection in troubled waters of that ideal world which existed above.  And the Chinese believed that as long as life on earth followed the pattern of the star world in every detail, there would be peace and happiness.  It was only when, owing either to insufficient knowledge or else to lack of skill in carrying out their instructions, the earth got out of step with the sky world that discontent and war and suffering followed.  If there was a famine, or rebellion, or civil war, it must be because the astronomers were held responsible.  It was a theory which certainly led to a rapid development of astronomical knowledge, especially when the unfortunate astronomers discovered that if they made a mistake, or even failed to predict and eclipese, they might lose not only their jobs but their heads as well."  (Peter Lum,The Stars in our Heaven, Myths and Fables, 1948, p. 16-17.)

        3.  Another version is given by Evan Hadingham, based on the  annals of the Formal Han Dynasty (202 B.C. - 8 A.D.).  The Chinese Emperor's rule was sanctioned, Hadingham says, by a blending of  earthly and cosmic forces.  The King was said to have Heaven for father and Earth for mother.  The main task of the state astronomers was to detect imbalances in this relationship by watching for portents such as eclipses, meteors, comets and other unusual celestial phenomena.  This responsibility placed them in a position of immense power in the Han bureaucracy.  An examination of the annals shows that the scribes edited them, making additions, deletions, and alterations.  Certain omens, such as eclipses, were reported on dates which were astronomically impossible, which suggests that the importance of obtaining a sign overrode the Han astronomers' concern for facts.  (Evan Hadingham, Early Man and the Cosmos (1984), p. 247; Hadingham cites W. Eberhard, "The Political Function of Astronomy and Astronomers in Han China" in Chinese Thought and Institutions, 1957, p. 38.) 

        4.  Some native Americans simply attributed errors of their astronomers to incompetence.  Ray Williamson speaks about the sun- watchers, or sun priests, functionaries of the Pueblo Indians, the Hopi and Zuni, who maintained a kind of solar horizon calendar by monitoring positions of the sun from day to day, and correlated them with various ceremonies, e.g., at the solstices.  He reports a journal entry for April 18, 1921, made by Crow Wing, a Hopi Indian:  "We think the Sun-Watcher is not a very good man.  He missed some places, he was wrong last year.  All the people think that is why we had so much cold this winter and no snow."  (Ray Williamson, Living the Sky, The Cosmos of the American Indian, 1984, chapter on sun-watchers and p. 111.)

         5.  We see why star-watchers, who were often also weather-watchers, were in demand.  We have a flourishing weather prediction industry today, also not as reliable as we would like.  We announce in our daily newspapers summer and winter solstices and equinoxes, eclipses, comets, meteor showers, and so on.  Supernovae are reported, and are especially valued by our cosmologist/astronomers, who use them to make predictions about the future and past of the whole universe.  Just as people have done for thousands of years, we teach our young how to read and use calendars, what solstices and equinoxes are, and how such things are related to predicting future changes in daily sunlight and weather.  We teach them current theories of how eclipses work, and what meteors and comets are thought to be.  We also find in our newspapers predictions about the affairs of individuals, in daily horoscopes written (one supposes) by astrologers.  And we hear of officials who consult astrologers about propitious times for taking actions.

        6.  Edward Schafer says of the role of astronomy and astrology in China during the T'ang dynasty (618-907 A.D.) that astronomical and calendrical affairs were a monopoly of the court.  This was because astronomical activities had a ritualistic and religious component which involved the sovereign, the Son of Heaven, who was the link between celestial energy flowing from above and terrestrial responsibility flowing from below.  Only the Son of Heaven could possess true knowledge of the stars.  Prying into such affairs could be treasonable.  To understand the workings and readings of the armillary sphere and star chart was to approach dangerously close to state secrets.  Thus ordinary citizens of the T'ang empire were forbidden to dabble in such matters.  Officials maintained that this taboo was intended prevent inexpert interpreters and charlatans from misleading and defrauding the ignorant masses.  There were stringent penalties for the possession and use of most implements and books which could be used to obtain exact astrological of what the T'ang code called "our occult counterparts in the sky".  (Edward Schafer, Pacing the Void, T'ang Approaches to the Stars, 1977, p. 11-12.)

         7.  "The 'star gods' of ancient China were not mere ensouled stars," says Schafer, "except, perhaps, to the vulgar.  They were inconceivable beings whose masks and costumes were always hanging in the Vestry or Green Room of the sky, ready for occasional use when the formless powers who owned them chose to show themselves more closely to advanced students of the Highest Clarity than they ever did to mortals whose vision was more clouded by the obsessive fogs of ordinary careers and mundane preoccupations.....  The beginnings of official Chinese worship and propitiation of these remote and sublime intelligences are lost in the roots of Chinese history.  In Han times [25-220 A.D.], however, when we begin to have some clear idea of official cult practices and beliefs, star-worship was already firmly established.  A prominent place was given to it in the state rituals connected with the worship of heaven carried out in the capital city.  An example, under the date of A.D. 26, was the great imperial sacrifice to Heaven, with offerings of oxen to the sky-gods, inaugurated in the southern suburb of Lo-yang.  The rite was conducted on a central round "altar" (i.e., ceremonial platform) and external altars to the five paramount gods of the directions.  The place of sacrifice was furnished with representations of the purple palace of the pole and with blazons representing the positions of the sun in the east, the moon in the west, and of the Northern Dipper.  There were also lesser altars for the planets.  These celestial deities were always paramount in the state cult, since they had a special relationship with the imperial house, the earthly nexus of the power that radiated from them."  (Schafer, ibid., p. 222-225.)

         8.  Schafer goes on to say that state ceremonies conducted by the Son of Heaven himself, or by his surrogates, were momentous and complex affairs in which numerous potent spirits were invoked.  At the winter solstice, in the most honorable position on a great round platform -- the northern one, facing south -- the imperial court worshipped the ritual presence of the "Supreme Theocrat of the Heaven of Primal Light".  This epithet refers to "the white radiance of the eternal breath which pervades the cosmos".  Schafer emphasizes that we should not regard Taoist star worship merely as worship of the stars.  If we do so, we misunderstand their faith as much as if we regarded the adoration of St. Michael and St. Gabriel as bird worship because these creatures of pure spirit are often represented with wings.  To the Taoists, the stars were not gods but tokens and guises of cosmic beings, who might assume other guises and reveal themselves in other symbols.  "They were deities whose location was nowhere, who existed simultaneously in the brain and in outer space, and could exhibit their numinous presence in any manner or place that seemed desirable."  Taoist priests and initiates wore special costumes which symbolized their spiritual advancement and embodied mana which was revealed outwardly by magical diagrams and talismans.  Their divinites were often described as wearing costumes just like those of their earthly hierophants.  Most prominent of these vestments was the "star hat", referred to very often in T'ang poetry.  A westerner might imagine this as the conical hat of an Arabian Nights' sorcerer, or white-bearded Merlin, or a fairy godmother, or a wicked witch.  However, it appears that no graphic representation of a Taoist star-hat has survived from T'ang times.  (Schafer, ibid.)

         9.  According to the Book of T'ang astrology was unnecessary in the golden ages of China's remotest past:  "In the Grand Tranquillity of antiquity, the sun was not eroded and the stars did not explode."  Is this a reference to sun spots, comets and meteors?  to supernovae?  In any case, after the rule of godlike supermen in the earliest times came to an end, Schafer says, "the skies over the Middle Kingdom were soon flashing with warnings from the All Highest."  Interpretation was needed.  The earliest Chinese astrology, like the earliest Mesopotamian astrology, was an omen or portent astrology, whose function was to predict on behalf of the monarch and nation.  The fate of individuals was only of interest as far as it bore on the fate of the empire.  Astrologers were officers of the kingdom, "devoted to the interpretation of strange lights and movements in the heavens, and the timely anticipation of disasters".

         10.  Apparently not long before the beginning of the Han dynasty, the body of lore associated with such startling phenomena acquired a theoretical framework, chiefly the cosmic dualism of  yin and yang, along with the doctrine of the Five Activities, which could be made to correspond with the five visible planets.  Along with these, there was a fundamental "theory of correspondences".  Schafer says:  "Celestial events are the "counterparts" or "simulacra" of terrestrial events, sky things have doppelgangers below, with which they are closely attuned.....  The germinal essences of the Myriad Creatures in every case have counterparts up in the sky."  They form shapes or contours under the sky.  "Correspondence" has been defined as the relation between the cosmic and political realms, and between the natural and human worlds, between macrocosm and microcosm.  The emperor, the Son of Heaven, is a critical nexus between them all, "dedicated to maintaining the exactness of the correspondences by means of ritual observances".  As a consequence, the early Chinese philosophers pondered relationships rather than substance, a matter which preoccupied the Eleatics.  However, Schafer observes, there were always skeptics.  (Schafer, ibid., p. 55-57.)

         11.  Among the earliest of the Chinese philosophical skeptics was Wang Chhung [27-97 A.D.], said by Joseph Needham and Wang Ling to have been "one of the greatest men of his nation in any age  ..."  They say: "[He] made a frontal attack upon the Chinese State 'religion' by an uncompromising resistance to anthropocentrism of any kind.  Again and again he returns to the charge that man lives on the earth's surface like lice in the folds of a garment.  At the same time, he admits that among the 300 (or 360) naked creatures, man is the noblest and most intelligent.  But if fleas, he said, desirous of learning man's opinions, emitted sounds close to his ear, he would not even hear them; how absurd then it is to imagine that Heaven and Earth could understand the words of Man or acquaint themselves with his wishes.  This position once gained, the whole weight of Wang Chhung's attack on superstition was deployed.  Heaven, being incorporeal, and Earth inert, can on no account be said to speak or act; they cannot be affected by anything man does; they do not listen to prayers; they do not reply to questions."  (Joseph Needham and Wang Ling, Science andCivilisation in China, v. 2, "History of Scientific Thought, 1969, p. 368, 374-375.)

         12.  Still, paradoxically, Wang Chhung favored individual or horoscopic astrology, and may even have introduced it into China.  He believed "that among the most important of all influences acting upon men during the formative period of their lives were those of the stars.....  The paradox lies in the probability that it was precisely Wang Chhung's scientific naturalism which pushed him into this theory. as a means of escaping from the arbitrary endowments of local gods and spirits and other 'supernatural' agencies.  The stars were at least regular in their motions." (Needham and Ling, ibid, p. 384.) 

         13.  The Chinese astral religion did not contain horoscopic astrology until relatively late.  This shows, on the one hand, how astral religion in general may be separate from astrology and in particular from horoscopic astrology, and on the other hand, how astral religion may be an important ingredient in a religion as a whole.  Charles Dupuis (1742-1809) went so far as to claim that all religions have grown out of astral religions.  Dupuis was a scholar who became a member of the revolutionary government in France in 1792, and also served briefly in Napoleon's government.  However, he soon retired from politics, and devoted the rest of his life to his studies.  In 1795 he published an extensive work called Origine de tous les cultes, ou la religion universelle in which he propounded his theory of the astral origin of all religions, and futhermore that the place where all organized religion originated was northern Egypt.  The work stirred up considerable controversy, and is said to have led to the expedition organized by Napoleon for the exploration of Egypt, an invasion which had enormous political and archeological consequences.

         14.  Few believe at present that all religion originated in Upper Egypt, or that all religion grew out of worship of celestial objects.  However, that astrolatry had a considerable influence on the development of many religions is undeniable, as shown by Dupuis's own impressive scholarship which covers a multitude of times and places and peoples.  He begins by asserting that in the beginning all religion was pantheistic.  Of the early idea of God, he says:  "When man began to reason upon the causes of his existence and preservation, also upon those of the multiplied effects, which are born and die around him, where else but in this vast and admirable Whole could he have placed at first that sovereignly powerful cause, which brings forth everything, and in the bosom of which all reenters, in order to issue again by a succession of new generations and under different forms.  This power being that of the World itself, it was therefore the World, which was considered as God, or as the supreme and universal cause of all the effects produced by it, of which mankind forms a part.  This is that great God, the first or rather the only God, who has manifested himself to man through the veil of the matter which he animates and which forms the immensity of the Deity."  (Charles Dupuis, The Origin of all Religious Worship, 1871, p. 15-16, anonymous translation of material from Dupuis' work.  It is difficult to trace the exact provenance of the material.  Dupuis's work of 1795 was revised by P. R. Auguis and published in 1822, 10th edition, 1835-1836.  An abridgement by Count M. de Tracy was published in 1804.  While the content, roughly speaking, of the anonymous translation into English can be found in the edition of 1835-1836, the semantically equivalent passages are quite different linguistically.)      

         15.  Dupuis goes on:  "Although this God was everywhere and was all, which bears a character of grandeur and perpetuity in this eternal World, yet did man prefer to look for him in those elevated regions, where that mighty and radiant luminary seems to travel through space, overflowing the Universe with the waves of its light, and through which the most beautiful as well as the most beneficent action of the Deity is enacted on Earth.  It would seem as if the Almighty had established his throne above that splendid azure vault, sown with brilliant lights, that from the summit of the heavens he held the reins of the World, that he directed the movements of its vast body, and contemplated himself in forms as varied as they are admirable, wherein he modifies himself incessantly."  Dupuis quotes Pliny the Elder (Natural History, II.1):  "The World, says Pliny, or what we otherwise call Heaven, which comprises in its immensity the whole creation, is an eternal, an infinite God, which has never been created, and which shall never come to an end.  To look for something else beyond it, is useless labor for man, and out of his reach.  Behold that truly sacred Being, eternal and immense, which includes within itself everything; it is All in All, or rather itself is All.  It is the work of Nature, and itself is Nature."  (Dupuis, ibid., p. 16.)

         16.  Later, Dupuis says:  "It would be a mistaken idea to believe, that [the Ancients] considered the World merely as a machine, without life and intelligence, moved by a blind and necessary force.....  As the World seemed animated by a principle of life, which circulates in all tis parts, holding it in eternal activity, it was believed that the Universe lived as man did and the other animals, or rather that these lived only because the Universe, being essentially animated, communicated them for a few instants an infinitesimal portion of its immortal life, which it infused into the coarse and inert matter of sublunary bodies.  Was it restored back to itself?  Man and beast died and the Universe alone, always alive, circulated around the remains of their bodies by its perpetual motion, and organized new beings,  The active Fire or the subtle substance, which animated it, by incorporating itself in its immense mass, was the universal soul of it.  This is the doctrine, which is embodied in the system of the Chinese, on Yang and Yin, one of which is the celestial matter, moveable and luminous, and the other the terrestrial one, inert and gloomy, of  which all bodies are composed."  (Dupuis, ibid., p. 49-50.)

         17.  "This is the dogma of Pythagoras," Dupuis continues, "contained in those beautiful verses in the sixth book of the Aeneid [of Virgil], where Anchises reveals to his son [Aeneas] the origin of the souls and their fate after death.  'You must know, my son, he said, that Heaven and Earth, the Sea, the luminous globe of the Moon and all the Stars, are moved by a principle of eternal life, which perpetuates their existence; that there is a great intelligent Spirit extended in all the parts of the vast body of the Universe, which, while mixing itself in All, is agitating it by an eternal motion.  It is this soul, which is the source of life of man, of the beasts, of the birds and all the monsters living within the bosom of the Ocean.  The vital force, which animates them, emanates from that eternal Fire, which shines in the Heavens, and which while it is held captive in the raw material of the bodies, is only developed as much, as the various mortal organizations permit it, which subdue its power and activity.  At the death of each creature, these germs of a particular life, these portions of an universal breath, return to their principle and to their source of life, which cirulates in the starred sphere.'"  (Dupuis, ibid., p. 50.)  

         18.  Matching lives of men with lives of stars is nearly universal.  In Africa, according to Harold Courlander, the following cosmogony is told among the Yoruba people of Nigeria.  "In ancient days, at the beginning of time, there was no solid land here where people now dwell.  There was only outer space and the sky, and, far below, an endless stretch of water and wild marshes.  Supreme in the domain of the sky was the orisha, or god, called Olorun, also known as Olodumare and designated by many praise names.  Also living in that place were numerous other orishas, each having attributes of his own, but none of whom had knowledge or powers equal to those of Olorun.  Among them was Orunmila, also called Ifa, the eldest son of Olorun.  To this orisha Olorun had given the power to read the future, to understand the secret of existence and to divine the processes of fate.  There was the orisha Obatala, King of the White Cloth, whom Olorun trusted as though he also were a son.  There was the orisha Eshu, whose character was neither good nor bad.  He was compounded out of the elements of chance and accident, and his nature was unpredictability.  He understood the principles of speech and language, and because of this gift he was Olorun's linguist ....."

         19.  "Down below, it was the female deity Olokun who ruled over the vast expanses of water and wild marshes, a grey region with no living things in it ....."  The two worlds were separate, and the orishas of the sky took no notice of what went on below, except for Obatala, King of the White Cloth.  In order to overcome the monotony of what lay below, he went to Orunmila to ask how land could be introduced below.  By casting palm nuts in his divining tray, Orunmila determined that Obatala should make a golden chain with which to descend to the water with sand, to make land with.  This Obatala did.  He planted a palm nut, and there was vegetation in the land, but no people, so Obatala decided to make people out of clay.  After making a number, he got thirsty and began to drink palm wine.  He drank so much that he got drunk, and some of the people he made after that were misshapen.  A city called Ife was founded.  Olokun, the orisha of the sea, angry that water had been covered with land, flooded it, and many people were drowned.  After a while, Orunmila, the deity of divination, whose name means "The Sky Knows Who Will Prosper", came down from the sky and turned back the sea.  He also taught certain orishas who had come to live below on the land, and certain men, the arts of controlling unseen forces, and others the art of divining the future, "which is to say the knowledge of how to ascertain the wishes and intentions of the Sky God.....  Earthly order -- the understanding of relationships between people and the physical world, and between people and the orishas was beginning to take shape."  (A Treasury of African Folklore, edited by Harold Courlander, 1975, p. 189-193; this story is from his own Tales of Yoruba Gods and Heroes, 1973.)

         20.  Lum relates that in the myths of Britain, the  constellation of the Great Bear (Ursa Major, the Big Dipper) is interwoven with the story of King Arthur and the Round Table. His name was alleged to have come from the words "Arth" and "Uthyr", meaning "bear" and "wonderful".  Some of his followers are said to have claimed that he was an incarnation of the spirit of the Great Bear.  The Round Table may have referred to the circle made by the swinging of the Great Bear's tail each night when it swept the northern sky.  "Fiona Macleod tells an old story," Lum says, "of how Arthur once fell asleep on the seashore, long before he had any thought of being king, and in his sleep a spirit came to him and guided him far up to the north where the stars of the Great Bear were bright.  There he found the knights of heaven seated at a great circular table, resplendent as the shining stars, and they spoke to him and gave him wise counsel.  They told him that his name should be Arthur, that he would be king, and that he must pattern his life and the rule of his kingdom on that of the kingdom of heaven."  (Lum, ibid., p. 38-39.)

         21.  Gene Weltfish tells how some Native Americans who lived along the Missouri River saw the connection of the heavens with the affairs of men:  "The Pawnees had many tasks to accomplish in the early spring before the time of planting.  Some of them were practical and some ceremonial, but to the Pawnees who believed that nothing on earth could move without the heavens, no practical task could be undertaken unless the appropriate ceremony had preceded it..... The round of spring renewal ceremonies was heralded by the appearance of two small twinkling stars known as the Swimming Ducks in the northeastern horizon near the Milky Way.  They notified the animals that they must awaken from their winter sleep, break through the ice, and come out into the world again." (Gene Weltfish, The Lost Universe: Pawnee Life and Culture, 1965,  p. 79.)  And Ray Williamson relates that according to Pawnee stories, they received from of their ritual direction from the stars.  They claimed that at one time they organized their villages according to patterns of the stars, and each village possessed a sacred bundle given to it by one of the stars.  When the different villages assembled for a communal ceremony, they arranged themselves in a way which reflected the celestial positions of the stars whose bundles they possessed.  There were 18 Skidi Pawnee villages, each associated with a different star." (Ray Williamson, Living the Sky, 1984, p. 229.)     

         22.  The Oglala Dakota, a branch of the Sioux Indians, were among those who defeated Custer at the battle of Little Bighorn in 1876.  (Cf. Evan S. Connell, Son of the Morning Star, 1984)  Their chief god, great spirit, creator and chief executive was (is?) Wakan Tanka, who is sixteen individuals in one, each of the four categories containing four individuals.  As great spirit, he is sky.  Paul Radin says of this religion:  "The sky is an immaterial god whose substance is never visible.  His titles given by the people are taku skan-skan and nagi tanka or the great spirit, and those given by the priests are skan and to, blue.  The concept expressed by the term taka-skan-skan is that which gives motion to anything that moves.  That expressed by the shamans by the word skan is a vague concept of force or energy and by the word to is the immaterial blue of the sky, which symbolizes the presence of the great spirit.  His domain is all above the world, beginning at the ground.  He is the source of all power and motion and is the patron of directions and trails and of encampment.  He imparts to each of mankind at birth a spirit, a ghost, and a sicun [an invisible god] and at the death of each of mankind he hears the testimony of the ghost and adjudges the spirit.  His word is unalterable except by himself.  He alone can undo that which is done.  His people are the stars and the feminine is his daughter."  (Paul Radin, Primitive Man as Philosopher, English translation 1927, p. 329-332, quoting James Walker, "The Sun Dance of the Oglala Divison of the Dakota," Anthropological Papers of the American Museum of Natural History, XVI, Part II, p. 72-92.)     

         23.  Plato speaks in many places of the workings of the stars.  For example, there is the myth of Er in the 10th book of Plato's meditation on the nature of justice,  the Republic.  Er, the son of Armenius, is killed in battle, but comes to life again just before he is to be burnt on a funeral pyre.  He describes what he has seen in the other world.  This includes a vision of the structure of the universe, described like this by Francis Cornford in his translation of the Republic:  "What the souls actually see in their vision is not the universe itself, but a model, a primitive orrery in a form roughly resembling a spindle, with its shaft round which at the lower end is fastened a solid hemispherical whorl.  In the orrery the shaft represents the axis of the universe and the whorl consists of 8 hollow concentric hemispheres, fitted into one another 'like a nest of bowls,' and capable of moving separately.  It is as if the upper halves of 8 concentric spheres had been cut away so that the internal 'works' might be seen.  The rims of the bowls appear as forming a continuous flat surface; they represent the equator of the sphere of fixed stars and, inside that, the orbits of the 7 planets.  The souls see the Spindle resting on the knees of Necessity.  The whole mechanism is turned by the Fates, Clotho (the Spinner), Lachesis (She who allots), and Atropos (the Inflexible).  Sirens sing eight notes on consonant intervals forming the structure of a scale (harmonia) which represents the Pythagorean 'music of the spheres.'"  (Republic, translated by Francis Cornford, 1941, p. 350.)

         24.  "All this imagery," Cornford concludes, "is, of course, mythical and symbolic.  The underlying doctrine is that in human life there is an element of necessity or chance, but also an element of free choice, which makes us, and not Heaven, responsible for the good and evil in our lives."  In the myth, after the souls have completed their journey to the Spindle resting on the knees of Necessity (probably the Milky Way) Lachesis, daughter of Necessity, distributor of human fates, says:  "Souls of a day, here shall begin a new round of earthly life, to end in death.  No guardian spirit will cast lots for you, but you shall choose your own destiny." (Cornford's translation, p. 355).  The dead souls are shown a large number of sample lives to choose from.  The man who had drawn the first lot chose, in thoughtless greed, to be reborn as a tyrant.  He did not see the many evils this life contained, and that he was fated to devour his own children.  Plato attributes his choice to innocence and ignorance:  "He was once of those," Plato says, "who had come down from heaven, having spent his former life in a well-ordered commonwealth and become virtuous from habit without pursuing wisdom.  It might indeed be said that not the least part of those who were caught in this way were of the company which had come from heaven, because they were not disciplined by suffering; whereas most of those who had come up out of earth, having  suffered themselves and seen others suffer, were not hasty in making their choice." (ibid., p. 357).  Cornford draws attention to Plato's intention that such stories be taken as myth.  By this means Plato synthesizes older speculative interpretations in the manner of Pythagoreans with newer ideas of rational philosophy.

         25.  Plato's visions still exerted great cultural force near the close of the 16th century, just before the advent of new cosmologies based on the works of such people as Copernicus, Kepler, Galileo and Descartes, unified by Newton in his system of the world.  At Florence, in 1589, an elaborate theatrical production known as the intermezzi was presented at the Medici court in honor of the marriage of the Grand Duke of Tuscany.  Here is the opening scene, as described by Roy Strong:  "On May 2nd 1589 the front curtain on the Teatro Mediceo parted to reveal a Doric temple and above it a cloud, surrounded by rays of light, which slowly descended to the ground.  On this rode the Doric Harmony, singing of her descent to mortals.....  The initial statement of the Doric Harmony was carried to fruition in the first intermezzo which took the form of a representation of the Harmony of the Spheres according to Plato's cosmology, and in particular as described in the tenth book of Plato's Republic.  The prospettiva [a view of the city of Pisa in perspective] was suddenly covered with star-spangled clouds.  Eight Platonic sirens plus two more of the ninth and tenth sphere sat on clouds telling how they had forsaken the heavens to sing the praises of the bride.  On a central cloud sat Necessity on a throne with a diamond spindle of the cosmos between her knees.  She was attended by the three Parcae or Fates and they in turn were flanked by clouds bearing the seven planets and Astraea, whose advent on earth signalled the return of the Golden Age.....  Above were twelve heroes and heroines, each pair embodying virtues attributed to the onlooking couple [the Duke and his bride].  Both the sirens and the planets joined in a dialogue describing the joy of the cosmos at so auspicious an alliance and as the clouds arose from the lower part of the stage sunlight streamed in, while above night approached.  A concluding madrigal expressed hopes of  'glorious heroes' as a result of the match.  As the cloud vision faded the stage was filled with sunlight, revealing the prospettiva of the city of Pisa....."  (Roy Strong, Arts and Festivals, Renaissance Festivals 1450-1650, 1973 (1984); p. 137 and 23-24.)

         26.  The Renaissance court festival, says Roy Strong, "unlike its medieval forebearers, stemmed from a philosophy which believed that truth could be apprehended in images.....  Our guide to it is a vast tract of literature, books of emblems and imprese and mythological manuals.  These compilations were an extension and elaboration, under the impact of Florentine Neoplatonism, of the inherited tradition of hidden meanings .....  Although these texts were known to the middle ages, they were studied with renewed fervour during the renaissance, when scholars examined them to recover a lost history or secret wisdom, pre-dating the Christian revelation, that was passed down through Moses and the Egyptian priests by way of Hermes Trismegistus to the Greeks.....  The acceptance of a pagan theology that descended from Zoroaster through Hermes Trismegistus to Orpheus, Pythagoras and Plato enabled Renaissance man to assimilate the whole heritage of classical mythology and history."  (Roy Strong, ibid.; we will talk about Hermes Trismegistus in a moment.)

         27.  In a relatively recent European account of the relation of astronomy to destiny, Goethe (1749-1832) writes:

        "Wie an dem Tag, der dich der Welt verliehen, 
        Die Sonne stand zum Grusse der Planeten, 
        Bist alsobald und fort und fort gediehen 
        Nach dem Gesetz, wonach du angetreten. 
        So musst du sein, dir kannst du nicht entfliehen, 
        So sagten schon Sibyllen, so Propheten; 
        Und keine Zeit und keine Macht zerstückelt 
        Geprägte Form, die lebend sich entwickelt..... 
        Das Liebste wird vom Herzen weggescholten, 
        Dem harten Muss bequemt sich Will und Grille. 
        So sind wir scheinfrei denn, nach manchen Jahren 
        Nur enger dran, als wir am Anfang waren." 

        ("The way the sun stood at the planets' greeting, 
        The way it stood the day the world endowed you, 
        You were from that time on developed 
        According to the law by which you entered. 
        Thus must you be, and you can't escape, 
        The sybils and the seers have said it; 
        No time nor force can disassemble 
        Imprinted form that grows itself in living..... 
        What's loved is kept away from hearts that want it, 
        Will and whim are shaped to a Must unyielding. 
        We only seem free, and after many years, 
        We're more bound than when we started.")

        28.  We have said that Stoics were devoted to astrology in the Hellenistic era.  There were others in that era who embraced astrology.  There were, for example, the Hermeticists.  The works called Hermetica, or the Corpus Hermeticum, are Greek and Latin writings of uncertain origin, evidently composed from about 200 to 500 A.D., which contain religious or philosophic teachings ascribed to Hermes Trismegistus, the "three-great" Hermes, perhaps a mythical person or god.  Some say this Hermes is not the Greek Hermes, but the Egyptian god Thoth, perhaps identified with Hermes by Alexandrian Greeks; however this is also uncertain.  William Grese says that "the predominant view is that the Hermetica are a Hellenistic development of Greek (especially Platonic and Stoic)  philosophy, and the leading exponent of this position has been André-Jean Festugière."  (William Grese, "Magic in Hellenistic Hermeticism, in Hermeticism and the Renaissance, Intellectual History and the Occult in Early Modern Europe, edited by Ingred Merkel and Allen Debus, 1988, p. 45.)  However, as Grese observes, in addition to the religious and philosophic elements in the Hermetica, there are also magical and astrological elements.  These writings are to this day an important part of the so-called occult tradition.

        29.  A definition of occult, in this sense, is given by Edward A. Tiryakian:  "I understand intentional practices, techniques, or procedures which: a) draw upon hidden or concealed forces in nature or the cosmos that cannot be measured or recognized by the instruments of modern science, and b) which have as their desired or intended consequences empirical results, such as either obtaining knowledge of the empirical course of events or altering them from what they would have been without this intervention ..... To go on further, in so far as the subject of occult activity is not just any actor, but one who has acquired specialized knowledge and skills nevessary for the practices in question, and insofar as these skills are learned and transmitted in socially (but not publicly available) organized, routinized, and ritualized fashion, we can speak of these practices as occult sciences or occult arts." (Edward A.Tiryakian, "Toward the Sociology of Esoteric Culture", American Journal of Sociology 78, 1972, p. 491-512; quoted by Mircea Eliade, Occultism, Witchcraft and Cultural Fashions, 1976, p. 48.)  The word esoteric is also used in this connection, and Tiryakian says "esoteric" systems are the "religio-philosophic belief systems  which underlie occult techniques and practices; that is, it [the word "esoteric"] refers to the more comprehensive cognitive mappings of nature and the cosmos, the epistemological and ontological reflections of ultimate reality, which mappings constitute a stock of knowledge that provides the ground for occult procedures." (quoted by Eliade, l.c., p. 48).  

        30.  F. L. Peters observes that Hermeticism was an extremely complex phenomenon.  The theoretical and speculative works of the Corpus Hermeticum were accompanied by an immense variety of tracts on practical Hermeticism, which is to say, on the manipulation of natural substances.  Hermeticism had a considerable influence on Muslim culture.  With the assistance, it seems, of Iranian astrologers, Hermes Trismegistus was incorporated into Islamic learning a generation before Plato or Aristotle found a firm base there.  Many Muslims believed in the influence of stars on individuals.  One of the greatest of the early Muslim scientists was al-Biruni (11th century a.D.).  Among his many works was an Instruction on the Elements of Astrology, which became a standard work on the subject.  Peters says:  "Once again, even in Biruni, one can see the two faces of Islamic science; the secular tradition of trigonometric functions, astronomical tables and schemes of world chronology was accompanied and contaminated by a parallel tradition of horoscopes, astral influences and elaborate theories of the descent of occult wisdom from the hoary past into the bosom of Islam ...  Each discipline had authentic credentials that established it as a science; and if astrology was somewhat less exact in its predictions, as Ptolemy willingly conceded, it was not more so than ethics, for example, with respect to geometry."  (F. L. Peters, Allah's Commonwealth, A History of Islam in the Near East 600-1100 A.D., 1973, p. 270, 274, 351.)

         31.  The Hermeticist Joannes Stobaeus (c. 500 A.D.), says:  "For the stars are the instrument of destiny; in acccordance with this they bring to pass all things for nature and for men."  (in Hermetica, edited by Walter Scott, 1924, v. 1, p. 434).  Scott translates a passage from the Latin Hermetic work known as the Asclepius as follows:

        "Asclepius:  But tell me, Trismegistus, what part of the government of the universe is administered by Destiny?."

        "Trismegistus:  That which we name Destiny, Asclepius, is the force by which all events are brought to pass; for all events are bound together in a never-broken chain by the bonds of necessity.  Destiny then is either God himself, or else it is the force which ranks next after God; it is the power which, in conjunction with Necessity, orders all things in heaven and earth according to God's law.   Thus Destiny and Necessity are inseparably linked together and cemented to each other.  Destiny generates the beginnings of things; Necessity compels the results to follow.  And in the train of Destiny and Necessity goes Order, that is, the interweaving of events, and their arrangement in temporal succession.  There is nothing that is not arranged in order; it is by order above all else that the Kosmos itself is borne upon its course; nay, the Kosmos consists wholly of order.  Of these three, the first is Destiny, which sows the seed, as it were, and thereby gives rise to all that is to issue from the seed thereafter; the second is Necessity, by which all results are inevitably compelled to follow; and the third is Order, which maintains the interconnexion of the events which Destiny and Necessity determine.  But Destiny, Necessity, and Order, all three together, are wrought by the decree of God, who governs the Kosmos by this law and by his holy ordinance.  Hence all will to do or not to do is by God's ruling wholly alien from them.  They are neither disturbed by anger nor swayed by favour; they obey the compulsion of God's eternal ordinance, which is inflexible, immutable, indissoluble.  Yet chance or contingency also exists in the Kosmos, being intermingled with all material things....."  (Hermetica, v. 1, p. 362-364.)

        32.  In the Lord's Prayer of the Christian New Testament we have:                   

                  "Our Father who art in heaven, 
                    Hallowed be thy name. 
                    Thy kingdom come, 
                    Thy will be done, 
                    On earth as it is in heaven." 
  

(Mark, 6.7-12 (Revised Standard Version, 1952, revision of American Standard Version, 1881-1885, 1901, in turn a revision of King James Version, 1611)      

         33.  The influence of Hermeticism in the European Renaissance, and on the origins of modern science has been much debated.  There can be no doubt that its influence was considerable in some ways.  A translation and publication of the Corpus hermeticum was completed in 1471 by Marsilio Ficino, and this and subsequent translations and related works were in considerable demand.  An ancient pedigree was sought for Hermes Trismegistus.  The pedigree according to Ficino runs from Plato (who, Ficino claims, couldn't have thought up all his wisdom by himself) to Philolaus, then to Pythagoras (said to have obtained his wisdom in Egypt), and so on, back to Hermes.  What about Hermes' source?  "Here," says Wayne Shumaker, "we pass out of the world altogether.  Mercury 'puts aside the fogs of sense and of fancy, bringing himself thus to an approach to mind; and presently Pimander, that is, the divine mind, flows into him, whereupon he contemplates the order of all things.'  The pedigree of the pimander [divine intelligence] terminates in God Himself, whose word must perforce be accepted."  (Wayne Shumaker, Occult Sciences in the Renaissance, A Study in Intellectual Patterns, 1972, p. 204.)  What emerges, says Shumaker, is una priscae theologiae ubique sibi consona secta, "a system of aboriginal theology everywhere harmonious with itself".  That is, a certain group of Renaissance scholars and their followers sought in the Hermetic writings a pattern which would allow the reconciliation of any pagan system with Christianity.  It was a kind of structuralism.  Shumaker remarks that a vestige of it is found in George Eliot's Middlemarch, in which Mr. Casaubon is attempting to work out a "Key to All the Mythologies."  The aim of Renaissance syncretists like Ficino (who was an enthusiastic astrologer) was not to contrast mythologies, nor to criticize them, but to unite them in a harmonious concordance.

         34.  In her Giordano Bruno and the Hermetic Tradition (1964) and subsequent works, Frances Yates tried to show that Hermeticism was a major influence on the development of modern science.  "The Renaissance magus," she says, "was the immediate ancestor of the seventeenth century scientist." (Frances Yates, "The Hermetic Tradition in Renaissance Science", in Art, Science and History in the Renaissance, 1968, edited by C. S. Singleton, p. 258.)  Karin Johannisson summarizes this point of view.  The Hermetic tradition in the Renaissance, she says, started in the 15th century with the translation of Neoplatonic writings by Marsilio Ficino and his circle in Florence, Italy.  This included the Corpus Hermeticum.  "Here," says Johannisson, "the proud notion of a pristine knowledge was depicted, a gift from God to Adam and an exhortation to Man to complete the work of creation by unlocking it and decoding its underlying structure ... Nature has its own language, and the means of interpreting it was a secret alphabet, derived from Greek number mysticism and the cabala, accessible only to the chosen."  This Hermetic tradition was carried further by Paracelsus and his followers, and such people as Cornelius Agrippa (1486-1535), John Dee (1527-1608) and Robert Fludd (1574-1637).  These traditions, according to Johannisson, were transformed into a concrete program in two renowned Rosicrucian manifestos, the Fama fraternitas (1614) and the  Confessio fraternitas (1615).  Johannisson takes these to have made a positive contribution to the development of early modern science.

         35.  "They maintained," Johannisson says, "the idea that knowledge cannot be limited by given methods, and that against rationality, objectivity, and critical doubt as the cardinal virtues of science must be polace proud hope that the boundaries of science can always be transcended, the dream of a perfectible science in the service of mankind."  Johannisson takes the story to the end of the 18th century, when during the years around the French Revolution, "the concepts of magic and science once again seem to merge in the intense mystical activity of the orders, and when the scientific academy and the secret society fulfill similar functions as platforms for scientific activity and propaganda."  (Karin Johannisson, "Magic, Science, and Institutionalization in the Seventeenth and Eighteenth Centuries", in Hermeticism and the Renaissance, Intellectual History and the Occult in Early Modern Europe, 1988, based on a 1982 meeting, edited by Ingrid Merkel and Allen G. Debus, p. 251-261.)

         36.  Johannisson asserts that a 16th and 17th magus considered himself to be a natural philosopher in the same way, say, as Kepler, Galileo and Newton were natural philosophers.  (The terms "scientist" and "physicist" were not yet in common use.)  "The magus," she says, "understands nature as an animate and active network of ultimately spiritual forces, the scientists sees it as a "machine," a manifestation of the universal laws of nature."  Thus Johannisson regards laws of nature as antithetical to spirituality, rather than as rules complementary to spirituality, or perhaps rules which even spirits must obey.  "The magus believes that because nature is animate -- not completed and finished -- he can enter into it, operate on it, and manipulate it."

         37.  But a magus is himself a part of nature, and had no choice about entering it.  And to say that nature is not complete is not to say that it doesn't obey natural laws, be they only laws of probability.  Johannisson says:  "The scientist on the other hand would not attempt to exceed nature; his task is to understand and to describe it, to come as close as possible to its unassailable mechanism; for him the laws of nature are inexorable and unbreakable, absolute criteria for what is natural and supernatural.  For the magus, the supernatural simply coincides with the unusual, the marvelous, the artificial; the laws of nature are not regarded as absolute and can be exceeded by art.....  Magic and science work with different methods.  Whereas science is based on the conviction that experience and reason are valid instruments of knowledge, magic is based on the conviction that such values cannot be fixed, and the aim is continually set far beyond the boundaries of what is empirically and rationally verifiable.  The theories of science are dictated by logic, those of magic by analogy.  In opposition to rationality and understanding (episteme) stand irrational hope and use (techne).  At its most general, then, magic can be characterized as the utilization of art in order to attain specific desired ends, not in order to attain knowledge and understanding.....  Magic strove to transcend the laws of nature, science to decode them, but also to accept subordination to them."  (Johannisson, ibid.)

         38.  But there isn't, and never has been, a clear demarcation between science as knowledge and understanding, and technology as use of science and other practical arts.  Scientists, on the whole, must use and create or rely indirectly on technology in their pursuit of understanding, and technicians must use and create scientific understanding in realizing their goals.  There is, however, a clear demarcation between technology as use limited by natural laws, and magic as use not limited by natural laws. 

         39.  "To summarize," Johannisson says, "magic as a scientific activity builds on a defined conception of knowledge -- derived from the Hermetic tradition -- stressing experiments and rationality in a mathematical sense, together with a visionary utopianism aiming at practical results."  The Hermetic tradition, however, shows few signs of appreciating what applied mathematics is like, as understood by such people as Archimedes, Newton, and mathematicians today.  On the contrary, Hermeticists are prone to engage in numerology, number mysticism and number magic, which are not applied mathematics in the same sense.

         40.  Number mysticism and numerology go back to ancient times.  The Hellenistic era, the period of the Hermeticists, the Gnostics, the Stoics, the Epicureans, the Academics, and early Christianity, was also the period of the Neoplatonists, who looked back not only to Plato but to the Pythagoreans, some of whom have customarily been taken to have been among the great mathematicians of ancient Greece, and some of whom (not necessarily the best mathematicians) were devoted to a kind of numerology.  How much of classical Greek mathematics was due to Pythagoras or his immediate followers, and how much to other pre-Socratic or later Greeks has been for a long time a difficult and debated question.

         41.  Pythagoras himself appears to have been a kind of shaman, "the wisest of men", a miracle-worker who founded a secret society in which he taught metempsychosis (the reincarnation or migration of souls), the music or harmony of the heavens or spheres, immortality of souls among the stars, and various magical rituals and practices.  Walter Burkert has been a relatively recent participant in the long debate about the relation of Pythagoras and Pythagoreans to the science of mathematics.  He holds that the general belief in  the Pythagorean origin of mathematics (mathematics, say, as Aristotle and Euclid understood it) stems from no earlier than the Neoplatonic and neo-Pythagorean scholastic traditions of late antiquity, many hundreds of years after the introduction of mathematical science in the 6th and 5th centuries B.C.

         42.  It is questionable that Greek mathematics originated in the revelation of a guru, within a secret society founded to do mathematics, since it arose in close connection with the development of Greek naturalistic views of the world by Pythagoreans and non-Pythagoreans alike.  Geometry was an important component of astronomy among the classical Greeks, and some of the geometers were not Pythagoreans.  Earlier than in other fields, geometry and astronomy became the domain of specialists because their increasing complexity required special talent, and the existence of such talent is independent of membership in any particular school.  The Sophists, who were not mathematically inclined, were detached from the natural philosophers, and the exactness of the mathematical parts of natural philosophy contrasted more and more with the uncertainty of other kinds of philosophy.  By Plato's time, mathematics was already the model science.  Individual Pythagoreans had some part in this development, but the mathematics of the classical Greeks was Greek, not merely Pythagorean.  (Walter Burkert, Lore and Science in Ancient Pythagoreanism, translation with authorized revisions by Edwin L. Minar, Jr., 1972, of Weisheit and Wissenschaft: Studien zu Pythagoras, Philolaus und Platon, 1962, p. 406, 426-427.) 

         43.  Some early Pythagoreans, perhaps including Pythagoras himself, were devoted to numerology, which Burkert takes to be of  pre-historic origin.  Indeed, number dominates the Pythagoreans' general view of the world.  But devotion to number in the form of number mysticism and number symbolism is quite different from devotion to mathematics as a science.  Burkert gives this as another reason that Greek mathematics in the manner of Euclid or Archimedes didn't arise from the Pythagoreans.  He says:  "It has long been known that conscious and unconscious, rational and irrational impulses, logic and mysticism, interpenetrate in a complicated and nearly inextricable fashion.  As Kepler discovered his second planetary law in 'Pythagorean' manipulation of regular polyhedra, so one might find it obvious that precisely the pre-philosophical lore of Pythagoras provided the stimulus for Pythagorean science.  But not only does the cosmic significance of number [as in numerology] come from pre-logical number symbolism, but, even in that which Aristotle presents as the philosophy of the Pythagoreans, there emerges again and again a spirit and method directly opposite to that of exact mathematics, so that the latter cannot have arisen from the activities of the Pythagoreans.  It is not an unbroken unit of science and religious-ethical teaching that we find in the Pythagorean tradition, but a groping attempt to mediate between two levels, to transpose an ancient interpretation of the world into the language of the recently founded philosophia."  (Burkert, ibid., p. 466, 479-480).

         44.  It appears, then, that the contrast of numerology with mathematics related to experience is found already among the pre-Socratic Greeks.  In the early 17th century, in the work of people like Johannes Kepler and Robert Fludd, heirs of a neo-Pythagorean revival in the European Renaissance of a neo-Pythagorean upsurge in Hellenistic times in North Africa, we find a mixture of the two, with mathematics and its relation to experience having mostly the upper hand in Kepler, and numerology and magic having mostly the upper hand in Fludd.  (I will give details about the contrast and clash between Kepler and Fludd later.)

         45.  Burkert concludes that the Pythagorean philosophy synthesized scientifically valid mathematics with scientifically invalid numerology.  He regards this synthesis as largely the the work of Philolaus, following some prodomal attempts by Hippasus.  He says:  "The tradition of Pythagoras as a philosopher and scientist is, from the historical point of view, a mistake.  But the fascination that surrounded, and still surrounds, the name of Pythagoras does not come, basically, from specific scientific connotations, or from the rational method of mathematics, and certainly not from the success of mathematical physics.  More important is the feeling that there is a kind of knowing which penetrates to the very core of the universe, which offers truth as something at once beatific and comforting, and presents the human being as cradled in a universal harmony.  In the figure of Pythagoras an element of pre-scientific cosmic unity lives on into an age in which the Greeks were beginning, with their newly acquired method of rational thought, to make themselves masters of their world, to call tradition into question, and to abandon long-cherished beliefs.  The price of the new knowledge and frreedom was a loss in inner security; the paths of rational thought lead further and further in different directions, and into the Boundless.  There the figure of the ancient Sage, who seemed still to possess the secret of unity, seemed more and more refulgent.  Thus after all, there lived on, in the image of Pythagoras, the great Wizard whom even an advanced age, though it be unwilling to admit the fact, cannot entirely dismiss." (Burkert, ibid., p. 480, 482.)46.  Nicomachus and Iamblichus and other neo-Pythagoreans of the 2nd through 4th centuries A.D. (part of the Hellenistic era, in the extended sense) associated numbers with ethical and social entities, taking themselves to be following a tradition established long before by the Pythagoreans themselves.  To take one case, justice was associated with square numbers, perhaps because there are two "balanced" factors in a square (4 = 2·2, 9 = 3·3 etc.).  One of Aristotle's commentators, Alexander of Aphrodisias, reports that some took the number 4 to represent justice, or even to be justice, since it is the least square of a whole number (not counting 1).  Others took 9 to represent justice, perhaps because (as a guess) it is the square of the "balanced" number 3 which has a beginning, middle and end.  The number 2 might be considered as balanced, but some Pythagoreans took odd numbers to be "limited" and even numbers to be "unlimited", and perhaps 3, as the least of the limited numbers, was considered more appropriate for justice.  Or maybe this wasn't the way it happened at all. W.K.C. Guthrie observes, thus complicating matters, that some late commentators took 3, 5 or 8 for justice.  (W.K.C. Guthrie, History of Greek Philosophy, 1967, v. 1, p. 303-304.)

         47.  To take another example, marriage is associated with 5, or is 5, because it is the union of male, associated with odd numbers (in particular 3), and female, associated with even numbers (in particular 2), and, of course, 3  + 2 = 5.  Again, opportunity, or "fit and proper" time was identified with 7 "because in nature the times of fulfilment with respect to birth and maturity go in sevens."  A man, for example, can be born after 7 months, cut teeth after another 7, reach puberty after the second period of 7 years, grow a beard after the third period of 7 years, etc.  As inaccurate as this sounds, the reckoning of human lives in multiples of 7 is said by Guthrie to have been a commonplace of Greek thought.     

         48.  Aristotle severely criticized theories of this kind in his Metaphysics.  Nevertheless, some of the followers of Pythagoras were some of those who initially developed the classical Greek mathematics which culminated with the works of such mathematicians and astronomers as Eudoxus, Euclid, Eratosthenes, Apollonius and Archimedes.  Many of these works are theoretically sound and of practical value to this day.  Mathematics, especially, has the peculiar property, among sciences, that while there continue to be new developments in it, often the old developments remain useful, or even essential.  On the whole, good mathematics may be forgotten, ignored, re-invented, re-formed or  reformed, extended, placed in more general contexts, placed on new foundations, and so on -- but not shown to be mistaken.

         49.  Edward Strong argues against such authors as E. A. Burtt (The Metaphysical Foundations of Modern Science, 1925) that the triumphs of mathematical philosophy in the work of people like Galileo, Descartes and Newton did not descend from the mathematical philosophy of the neo-Platonists and neo-Pythagoreans which had been elaborated by a number of Italian philosophers in the 15th and 16th centuries.  "The Florentine Platonism of the fifteenth century and the Pythagorean-Platonic metamathematics of the sixteenth century are not historically eligible for the honor of having instructed men to turn from classification to measurement."  (Edward W. Strong, Procedures and Metaphysics, A Study in the Philosophy of Mathematical-Physical Science in the Sixteenth and Seventeenth Century, 1936, p. 10.)

         50.  The "classification" which Strong refers to is a kind of numerology, and the measurement a kind of applied mathematics.  In Platonic philosophy, numbers, as such, have an intermediate existence between what can be sensed and the eternal ideas of which they are instances.  Among the neo-Platonists, this led to a kind of theological mathematics, as Strong calls it.  This is found in such neo-Platonists as Nicomachus and Theon.  "Neither one," Strong says, "attempts to deduce mathematical or 'scientific' truths from the mystery of numbers; rather we see them treating number as possessing properties which they insist is other than that of their arithmetical work.  Both recognize that arithmetic is a self-contained science, but they also consider it as the way of initiation into realities which lie beyond the limited procedures of the mathematicians."  (Edward Strong, ibid., p. 28.)

         51.  In theological arithmetic, properties of the soul, society, ethics, the elements, and so on, are identified with numbers by a succession of analogies.  "Numbers provide a symbolism and method of classification -- a symbolism of unity and multiplicity in explaining creation, and a classification of hierarchical relationships and essential virtues by means of triadity and triangularity, and so forth.  Number as a kind of  'universal and exemplary plan' in the mind of God has its fundamental meaning not so much in the notion of law as in the notion of efficacy or power .....  Efficacy and creation rather than law and quantitative relations, divinity rather than demonstration, divine numbers as transcending the physical and mathematical rather than a vision of mathematical order 'saving' appearances: these contrasts emphasize the transformation which mathematics undergoes in its elevation to the status of divine arithmetic."  (Edward Strong, ibid., p. 33.) 

         52.  In ancient Hebrew, Greek and Arabic, numerals are letters of the alphabet, though perhaps specially marked in some way.  It appears to have been this that gave rise to the view that hidden meanings and correspondences of written words can be found by adding together the numerical values of their letters.  Among the Jewish cabalists, this was known as gematria, among the Greeks isopsephia, among the Muslims, hisab al-jumal.  (Cf. George Ifrah, From One to Zero, A Universal History of Numbers. 1985, translation by Lowell Bair of Histoire Universelle de Chiffres, 1981, Part IV, Ch. 16-21.)  Various Christian writers also use the technique.  Such techniques are still practiced today, here and there.  Idries Shah gives a number of examples in one of his works on the Sufi mysticism of the Muslims, which began to spread with the advent of Islam in the 7th century of the Christian calendar, and which still lives today.  Shah regards the Sufis to have means of contacting the underlying wisdom of humanity, and to "correspond to the inner reality of Islam, as with the equivalent aspect of every other religion and genuine tradition."  (Idries Shah, The Sufis, 1964, p. 28)

         53.  Unfortunately, this wisdom seems to exist largely in cryptic or secret form, and illogicality is said by Shah to be a key feature of Sufism.  In any case, in Arabic, most words can be assigned roots consisting of 3 consonants.  Many words will then have the same root.  Furthermore, there is a standard way of associating letters of the Arabic alphabet with numbers (given on p. 174 of The Sufis).  The Hisab el-Jamal (different transliteration of the hisab al-jumal of Ifrah?) is said to be the "standard rearrangement of letters and numbers". (Shah, p.110.)  With these things in mind, Shah says, in a comment on the significance of "dots" to Sufis:  "Among the Sufis, NQT -- "dot," "point," sometimes "abbreviation" -- has an important value in conveying teachings.  In one aspect this is connected with the mathematical part of Sufism.  The Arabic word for "geometrician" or "architect" is muhandis.  It is composed of the letters M, H, N, D, S, which are equivalent to the numbers 40, 5, 50, 4, 60.  These total 159.  These numbers, resplit conventionally into tens, hundreds and units, yield 100 = Q, 50 = N, 9 = T.  These three consonants, combined in the order 2,1,3, provide the root NQT.  This root means "dot," "point."  In certain ceremonial usages, therefore, the word "point" is used to convey the concealed word which is its parent -- the word muhandis, the Prime Builder." (Shah, ibid., p. 372.)

         54.  Gershom Scholem describes a short Jewish work called the Sefer Yesirah or Book of Creation which seems to date from the 2nd or 3rd century A.D.  It circulated widely in many lands during the European Middle Ages, and is found today even outside of academies, especially among occultists.  Scholem considers that it probably originated from neo-Pythagorean sources such as the writings of Nichomachus of Gerasa (c. 140 A.D.), together with the idea of "letters by means of which heaven and earth were created" which may have come from within Judaism. 55.  The basic thesis of the work, accoording to Scholem, is that:  "All reality is consituted in the three levels of the cosmos -- the world, time, and the human body, which are the fundamental realm of all being -- and comes into existence through the combination of the twenty-two consonants [of the Hebrew alphabet], and especially by way of the '231' gates, that is, the combinations of the letters into groups of two (the author apparently held the view that the root of Hebrew were based not on three but on two consonants)."  The 22 consonants are divided into 3 groups according to a peculiar phonetic system.  The groups contain 3, 7 and 12 letters.  The group of three consists of "matrices" (sometimes translated "mothers"), corresponding to ether (or spirit), water and fire.  From these everything else came into being, and correspond also to the 3 seasons of the year (3 rather than 4 was an ancient Greek partitioning), and the 3 parts of the body: head, torso and stomach.  The letters in the group of 7 correspond especially to the 7 planets, 7 heavens, t days of the week and 7 orifices of the body.  They also represent 7 fundamental opposites: life and death, peace and disaster, wisdom and folly, wealth and poverty, charm (or beauty) and ugliness, sowing (or fruitfulness) and devastation, domination and servitude.  And they correspond to the six directions of heaven: above (or height), below (or depth), east, west, north and south [presumably the 7th is earth, or an observer?]  The 12 remaining consonants correspond to the 12 principal activities of man, the 12 signs of the zodiac, the 12 months of the years, and the 12 chief limbs of the human body.  Scholem observers that the scheme of the Sefer Yesirah betrays its relationship with astrology, although it is based on language mysticism.  From such ideas, says Scholem, "direct paths lead to the magical conception of the creative power of letters and words"  (Gershom Scholem, p. 24-35 of origins of the Kabbalah, 1987, translation of ursprung und Anfänge der Kabbala, 1962; there is an English translation of the Sefer Yesirah by Knut Stenring under the title The Book of Formation or Sepher Yetzirah, 1923, and another in The Qabala Trilogy, unattributed, called the "The Sepher Yetsira", from the French translation by Carlo Suarès, 1968.  (Gershom Scholem, p. 24-35 of origins of the Kabbalah, 1987, translation of Ursprung und Anfänge der Kabbala, 1962; and another in The Qabala Trilogy, 1985, unattributed, called "The Sepher Yetsira" based on the French translation by Carlo Suarès, 1968.

        56.  There have been numerous other species of number magic and mysticism.  Examples are beliefs in special values of certain numbers, such as a belief that 7 must be especially significant since in Genesis God is said to have created the universe in 7 days, and there are many other places in the Bible where the number 7 appears.  The connection with the Bible is stressed in an unusually elaborate and worked out treatment of the religious significance of small integers in two volumes by the Christian writer Paul Lacuria (Les Harmonies de l'être, exprimée par les nombres, 1899. The number 7 is especially considered in Chapters XV-XVIII. Sample: the 7 divine attributes Life, Liberty, Light, Holiness, Wisdom-Justice (linked) and Eternity correspond (in these orders) to the colors red, orange, yellow, green, blue-indigo and violet, to the musical notes do, re, mi, fa, sol-la (linked), ti (v. 1, p. 196-197), and the integers 1 through 7.    Of course there are also 7 days in a week, according to the ancients 7 "planets" (Moon, Mercury, Venus, Sun, Mars, Jupiter, Saturn), etc.

        57.  Henry Corbin describes the "science of the balance" ('ilm al-Mîzân) associated with the Muslim writer Jâbir ibn Hayyân, as described by the Muslim Shî-ite writer Haydar Amli (8th century A.D., 14th century A.H.), and said by him to have been originated by Pythagoras.  Haydar Amôli explains that 1 is the cause of number, 2 is the number of the First Intelligence as second existence; 3 is the number of the universal Soul; 4 is the number of nature; 5 of "prime matter"; 6 of space ("corporeal volume"); 7 of the celestial Sphere; 8 of the Elements; 9 of the 3 natural kingdoms, mineral corresponding to 10's, vegetable corresponding to 100's, animal corresponding to 1000's.  "Each number carries by itself an esoteric secret which is not found in any other number."

        58.  There are "balances" of 7 and 12, "correspondences between the astronomy of the visible [exterior] Heaven and the astronomy of the spiritual [interior] Heaven, between the esoteric hierarchy and its cosmic correspondences."  The 7 divine attributes as given here are Life, Knowledge, Power, Will, Word, Hearing and Sight, to which correspond 7 names called the "Imams of the divine Names".  In the spiritual world, there are 7 prophets who are manifestations of the 7 "ecstatic Angels of love": Adam, Noah, Abraham, Moses, David, Jesus and Mohammad.  There are 7 planets, 7 climates corresponding to them, 7 Earths and 7 peoples who inhabit them, and 7 degrees of hell.  One has the 12 primordially created angels, the 12 Imams who are the 12 friends of God, and the 12 signs of the zodiac.

          59.  There is also a "balance" of 19, which is of greatest importance, "for the system of the world is ordered according to the number 19."  This is because "the whole universe is in the image of God."  There are 7 planets and 12 signs of the zodiac: total 19.  There are the Intelligence and Soul of the universe, 9 celestial spheres, 4 elements, 3 natural kingdoms, and Man:  total 19.  There are 7 great prophets and 12 Imams belonging to them: total 19.  The 28 letters of the Arabic alphabet are reduced to 19 "degrees" of letters by a rather complicated process.  And so on.  There is a balance of 28, and other balances.  Corbin ends his treatment of this numerological system with a description, derived from  Ibn 'Arabî of the "knights of the invisible", the Sages who, it is said in the Koran, understand the true meaning of certain parables:  "it is thanks to them that we can have in this world a 'science of correspondences'."  (Henry Corbin, Temple et Contemplation, Essais sur l'Islam Iranien, 1980, "La science de la balance et les correspondences entre les mondes en gnose islamique, p. 67-141.)     

          60.  Another familiar kind of numerology is a belief in magical properties of square matrices of numbers, "magic squares", in which the entries are the integers from 1 to n2 for some n, and the sums are the same in rows, columns and main diagonals.  For example, if the 4 rows 1-15-14-4, 12-6-7-9, 8-10-11-5, 13-3-2-16 are arranged into a square in this order, the sums are all 34.  This particular example appears in a work called Oedipus Aegyptiacus (1652) by Athanasius Kircher, a noted 17th century Jesuit "Hermetic pseudo-Egyptologist" (so characterized by Frances Yates, The Rosicrucian Enlightenment, 1972, p. 230; the square is given by Hans Biedermann, Handlexikon der magischen Künste, 2nd edition, 1973, p. 316.)

         61.  Such correspondences fail to be applied mathematics, as mathematicians today understand this term, because the mathematical structures don't correspond naturally to anything in the events or things they are purported to apply to.  Gematria, the association of numbers with qualities like justice or institutions like marriage are examples of what I call appliquéed  mathematics.  This is an attempt to attribute a mathematical structure to something which doesn't have a mathematical structure, or at least has no interesting or revealing mathematical structure.  One may be trying to quantify the unquantifiable.  Examples might be attempts to apply partial differential equations to political movements in ways in which such equations are applied to physical phenomena (although statistical sampling methods as used in polls might be applicable), or to the movements of Beethoven's symphonies (which isn't as wild an idea as it might seem, since timed sounds can in a certain sense be specified by such equations).  Natural philosophers and their descendants, the natural scientists, must submit to the mathematics which is in the cosmos;  magicians and astrologers try to force some mathematics on it which doesn't belong to it.  

         62.  Edward Strong warns that the cabalistic and numerological maneuvers of such Florentine Platonists and Hermeticists as Marsilio Ficino and Giovanni Pico did not provide a metaphysical foundation for the 16th and 17th century mathematical philosophers.  These Platonists were neither mathematically nor empirically minded.  They were concerned with such problems as comparing the views of Plato and Aristotle on knowledge and being, and with the reconciliation of neo-Platonism and Hermeticism with orthodox Christianity.  They did not engage in a mathematical realism, but in a mystical number symbolism.  "Through love and through the knowledge of superior numbers, one penetrates into the inner mysteries.  The way upward yields to spiritual love; but if one would know the workings of the creative spirit in the created things, he should consider symbolic number.  As in Proclus, the divine numbers are defined in respect to their status and function: their status is to symbolize and classify the incorporeal and incorruptible beings, and their function is to create copies in matter.  Upon its own showing, the doctrine does not display the universe as a structure of mathematical order and relations.  Rather, a religious and mystical system borrows number as a useful symbol of incorporeality and turns arithmetic into arithmology.  The divine appropriates the arithmetic, and arithmetic the divine, in the 'divine arithmetic' of these Neo-Platonists."  (Edward Strong, ibid., p. 196-197.)

          63.  The distinction between applied and appliquéed mathematics was made by Kepler (not in these terms) in his controversy with the physician, Robert Fludd, who was also an alchemist, astrologer and Hermeticist.  This interchange is described by (among others) Max Caspar in Kepler, 1946, translated from German by C. Doris Hellman, 1959, p. 290-293; by the Nobel physicist Wolfgang Pauli, "The Influence of Archetypal Ideas on the Scientific Theories of Kepler", in Naturerklärung und Psyche by Carl Jung and Wolfgang Pauli, 1952, English translation by Priscilla Silz in The Interpretation of Nature and the Psyche, 1955; by Frances Yates in Giordano Bruno and the Hermetic Tradition, 1964, p. 440-444; by Robert Westman, "Nature, art, and psyche", in Occult and Scientific Mentalities in the Renaissance, 1984, p. 177-229;   and by Judith V. Field in Kepler's Geometrical Cosmology, 1988, p. 179-187.   

         64.  It appears to have been Kepler's harmony theory which led to the controversy with Fludd, who also had propounded a theory of musical correspondences in his Utriusque Cosmi ...  historia (1617-1618).  In Kepler's appendix to his Harmonice mundi (1619 -- sometimes called Harmonices mundi), Kepler compares his own work with that of Ptolemy in the 3rd book of Ptolemy's Harmonica, and also with the work of Fludd.  As to Fludd, Kepler objects that whereas he (Kepler) develops musical theory in considerable detail and then demonstrates a celestial counterpart, Fludd gives a condensed version of a textbook for musicians, and then deals with practical matters of music-making.  Kepler says: "...  he differs from me as a practitioner from a theoretician.  For while he considers [musical] instruments themselves, I investigate causes or consonances in nature, and when he teaches how one can compose a tune with many voices, I produce instead many mathematical demonstrations, that are in songs formed by nature as well as choral pieces."  (Johannes Kepler, Harmonice mundi, 1619, vol. 6 of Gesammelte Werke, p. 374;  cf. the translation into German by Max Caspar, Weltharmonik, 1939, reprinted 1971, which has something like this, translated into English (p. 362):  "For while he [Fludd] considers the instruments, I investigate the causes of nature or consonances, and when he teaches how one composes a song with many voices, I produce instead of this mathematical proofs for very many laws that are valid for choral as well as the many-voiced singing out of nature."      

         65.  Furthermore, Kepler observes that Fludd derives his harmonies purely from properties of numbers, whereas he (Kepler) finds his from astronomical measurements.  Indeed, Fludd never makes any reference in his theories to an observed astronomical quantity.  Kepler remarks that Fludd's Hermetic analogies 'are dragged in by the hair'.  Field says:  "The crucial difference between Kepler and Fludd seems ... to be that Kepler demanded that his cosmological theories should be in good numerical agreement with measured properties of the observable Universe." (l.c., p. 187.)  That is, the mathematics should be applied, not appliquéed. 

         66.  In Fludd's opinion Kepler's science refers only to the "outside of things", whereas he (Fludd) penetrates to the inner, invisible depths and holiness of things.  Fludd distinguished between formal mathematics (his own kind) and vulgar mathematics (Kepler's kind).  The mathematics of Fludd was, in fact, largely numerology -- a kind of purely verbal manipulation of numbers.  These verbal manipulations were, in turn, often extracted from or references to elaborate engravings which were basic in Fludd's system.  This has been emphasized by Westman who says we must look at Fludd's engravings "not as illustrations but rather as ways of knowing, demonstrating, and remembering."  (Westman, ibid., p. 181.)  Fludd's pictures, however, do not function in the way geometrical diagrams do for Kepler.  "It is as though Fludd's pictures," Westman says, which appear to be about nature, are really pictures of psychic states; they are visualizations of intuitions and feelings projected onto the world, but lacking any sufficient criterion of correspondence to an external reality."  (ibid., p. 211.)

          67.  The mathematics of Kepler (1571-1630) was awakened in him by the cosmos, tested by way of observations, and found not to be purely a matter of words.  "The divine voice," he says in the Astronomia nova (1609), "which commands men to learn astronomy, expresses itself in the world, not in words and syllables, but through things themselves and through the agreement of the human intellect and senses with the entirety of celestial bodies and phenomena." (Quoted by Alexandre Koyré, Astronomical Revolutions, 1973, p. 163, translation by R. E. W. Maddison of La révolution astronomique, 1961).)  Kepler's pictures -- geometric diagrams -- were projections of correspondences between geometrical relations and images in his mind and geometrical relations realized outside him.   Kepler's view in his Harmonice mundi of the relationship between the human mind and the Divine Mind -- based on an analogy with the center, circumference and radii of a circle -- fits in very well, as Pauli observes, with an interpretation of knowledge as a "matching" of external impressions with pre-existent inner images. (Pauli, ibid., p. 162.)

         68.  Kepler says:  "For, to know is to compare that which is externally perceived with inner ideas and to judge that it agrees with them, a process which Proclus expressed very beautifully by the word "awakening," as from sleep.  For, as the perceptible things which appear in the outside world make us remember what we knew before, so do sensory experiences, when consciously realized, call forth intellectual notions that were already present inwardly; so that that which formerly was hidden in the soul, as under the veil of potentiality, now shines therein in actuality.  How, then, did they [the intellectual notions] find ingress?  I answer: All ideas or formal concepts of the harmonies, as I have just discussed them, lie in those beings that possess the faculty of rational cognition, and they are not at all received within by discursive reasoning; rather they are derived from a natural instinct and are inborn in those beings as the number (an intellectual thing) of petals in a flower or the number of seed cells in a fruit is innate in the forms of the plants."  (quoted by Pauli, ibid., p. 162-163.)

          69.  Kepler's cosmic harmonies are given by proportions.  For example, Kepler asserted in the Harmonices mundi that the slowest angular velocity of a planet at aphelion (position on the planet's elliptical orbit furthest from the sun) is to the largest angular velocity of the planet at perihelion (position nearest the sun) as one small whole number is to another.  Stated in another way, the ratio of the angular velocities equals the ratio of two whole numbers.  One of the ratios in this proportion (a proportion is an equality of ratios) is between two whole numbers, but the other is between two quantities (the velocities) which can be represented by geometrical magnitudes.  Furthermore, Kepler calculated that the ratios of the small whole numbers were ratios corresponding to consonant musical intervals, such as a fifth, or a major or minor third, and thus, for example, equal to the ratios of the lengths of a string (or strings) which would produce the sounds of these intervals.  For example, for Mars, he found a fifth, and for Earth, a minor semitone.  (Alexandre Koyré, The Astronomical Revolution, 1973, p. 335; translation by R. E. W. Maddison of La révolution astronomique, 1961.)

         70.  When two geometric magnitudes, or magnitudes which can be represented by geometric magnitudes (such as velocities or weights) are compared in a ratio, the terms in the ratio must be in the same units -- for velocities, both feet per second, or both kilometers per hour, etc.  Kepler's third law of planetary motion maintains that the squares of the periods (times taken for one revolution around the sun) of two planets are to each other as the cubes of the semi-major axes of the elliptical orbits on which they move (approximately) -- provided the the two periods are in the same units, and the two lengths of the semi-major axes are in the same units.  The periods, or the lengths of the semi-major axes, might be incommensurable (in the mathematical sense, related to the difference between rational and irrational numbers) with some unit of measure, but the ratios could still be equal to a ratio of small whole numbers.  For example, in modern terms, the ratio of 3 times pi to 2 times pi equals the ratio of 3 to 2.

          71.  Kepler took geometry to be fundamental to God's creation, and God's geometrical relationships to be basic features of the cosmos which can be awakened in us by our sensory contacts with the world outside us.  He criticized the algebraists of his time for their lack of depth and their utilitarian attitudes.  When it is a question of the foundations of mathematics, he said, it is necessary to return to geometry. (cf. Gérard Simon, Kepler astronome astrologue, 1979, p. 149-153.)  The cosmic harmonies which he derived he considered to be characteristic of the cosmos by virtue of the fact that they arose from taking ratios of geometrical magnitudes which appear in nature, and in us.  That the magnitudes which appear in us do indeed correspond to the ones outside of us can be verified by making measurements outside of us to see if the proposed ratios of these magnitudes do indeed obtain.  However, he says in the Harmonice mundi that we are born with archetypal harmonies in our soul which are not images of harmonies, but the harmonies themselves -- indeed, these harmonies are the soul.  (Simon, ibid., p. 141.)  Fludd also was much concerned with cosmic harmonies, but Kepler complained that Fludd's ratios did not arise from taking ratios of objective geometrical magnitudes, but from subjective and arbitrary assignments of numbers to various pictures which Fludd carried around in his mind.  Fludd's ratios were ratios of small whole numbers not connected with actual cosmological magnitudes, except in the case of musical intervals.      

         72.  Pauli remarks on Fludd's aversion to the quantitative, in the sense in which physicists take this word.  In Fludd's system, there are two polar fundamental principles, form as a principle of light, coming from above, and matter, a dark principle, dwelling in the earth.  Pauli says:  "Fludd's depreciation of everything quantitative, which in his opinion belongs, like all division and multiplicity, to the dark principle (matter, devil), resulted in a further essential difference between Fludd's and Kepler's views concerning the position of the soul in nature.  The sensitivity of the soul to proportions, so essential according to Kepler, in in Fludd's opinion only the result of its entanglement in the (dark) corporeal world, whereas its imaginative faculties, that recognize unit, spring from its true nature originating in the light principle (forma).  While Kepler represents the point of view that the soul is a part of nature, Fludd even protests against the concept "part" to the human soul, since the soul, being freed from the laws of the physical world, that is, in so far as it belongs to the light principle, is inseparable from the whole world-soul." (Pauli, ibid., p. 198-199.)  It appears that Fludd used the word forma rather as we commonly use the word symbol today.      

         73.  Pauli says:  "Fludd's attitude, however, seems to us somewhat easier to understand when it is viewed in the perspective of a more general differentiation between two types of mind, a differentiation that can be traced throughout history, the one type considering the quantitative relations of the parts to be essential, the other the qualitative visibility of the whole.  We already find this contrast, for example, in antiquity in the two corresponding definitions of beauty: in the one it is the proper agreement of the parts with each other and with the whole, in the other (going back to Plotinus) there is no reference to parts but beauty is the eternal radiance of the "One" shining through the material phenomenon.  An analogous contrast can also be found later in the well-known quarrel between Goethe and Newton concerning the theory of colours:  Goethe had a similar aversion to "parts" and always emphasized the disturbing influence of instruments on the 'natural' phenomena." (Pauli, ibid., p. 205-206.)

         74.  Kepler's mathematical images didn't always participate in correspondences in the way Kepler thought they would to begin with  -- as comparison with nature external to him revealed to him at times -- but in his view, they were intended to be used to establish correspondences of something implanted in him with something outside of him.  Furthermore, his mathematics was based on the works of great mathematicians of antiquity such as Euclid, Apollonius and Archimedes, augmented by the work of numerous later "vulgar" mathematicians of the same kind (to use Fludd's pejorative designation), including himself.  Most of this mathematics is as valid today as it ever was, and much of it is still widely applicable, though often buried in complex mathematical systems and traditions elaborated since Kepler's time.

         75.  Kepler was sometimes extravagant in his correspondences, by today's standards.  For example, there was his proposal in the Mysterium cosmographium (1st edition, 1597; 2nd edition with extensive added notes, 1621) that the number and distance of the planets follow a priori from properties of the five regular solids.  However, he devoted incredible labor to testing this proposition against Tycho Brahe's observations.  In his last major work, the Harmonices mundi (1619), this proposition had evolved into Kepler's third law of planetary motion, that the squares of the periods of the planets are proportional to the to the cubes of the semi-major axes of the ellipses in which they move.  This law still stands, to a first approximation.  Kepler's theory of the connection of musical harmony with the motions of the solar system, a quantitative theory of the Pythagorean "music of the spheres", elaborated in the Harmonices Mundi, hasn't fared as well as his laws of planetary motion.  But it was not occult philosophy.  "I hate all cabalists," said Kepler.      

         76.  Pauli commented on the difference between people like Kepler, who are concerned with the quantitative relations between parts of things, and people like Fludd, who are concerned with qualitative visibility of wholes of things.  There are other contrasts between the viewpoints of Fludd and Kepler.  One lies in the use of language.  In Chapter V of his work De stella nova (On the new star) (1606), Kepler argues at some length that the names of the signs of the zodiac are arbitrary, and don't have any occult significance.  Gérard Simon observes that these pages are characteristic of Kepler's attitude, and show that Kepler grasped the fact that traditional judicial astrology is based on a lack of distinction between the thing and the symbol, between the symbol and the name, between the name and the meaning.  "It is a question," Simon says, "of knowing if words conform to things."  (Gérard Simon, ibid., p. 102.)

         77.  In the appendix to the Harmonices mundi, Kepler accuses both Ptolemy and Fludd of concocting cosmic harmonies which are "pure symbolisms ... poetical and rhetorical".  It's an old story: the debate about the relation of language to the rest of reality, which goes back at least to Plato's Cratylus.  The example of the zodiac doesn't reveal the profundity of the question.  It is quite easy to believe that the names of the signs of the zodiac are named after quite arbitrary shapes assigned to certain constellations, and that, for example, Libra, the Scales,  has no particular connection with justice or fair-mindedness (although astrologers believe otherwise).  But is all use of language arbitrary in this way?

         78.  In the De stella nova, Kepler ridicules the cabalists for regarding language as a direct gift of God, and for extracting extravagant hidden meanings from words and phrases by transposing their characters.  It must be remembered, though, that on the basis of the book of Genesis, the cabalists believed, as do many others, that God spoke the world into existence.  And, as Robert Westman brings out, Fludd's major works are of the genre of commentaries on Genesis, and while "Fludd had a strong interest in the created world of nature -- perhaps much more so than preceding commentators on Genesis -- his ultimate concern was still with Genesis itself."  (Robert Westman, "Nature, Art and Psyche" in Occult and Scientific Mentalities in the Renaissance, 1984, p. 125-229, especially p. 191-200; Westman cites Arnold Williams, The Common Expositor: An Account of the Commentaries on Genesis, 1527-1633, 1948.)

         79.  Brian Vickers examines the distinction between analogy and identity, and between literal and metaphorical language.  He says:  "In the scientific tradition, I hold, a clear distinction is made between words and things and between literal and metaphorical language.  The occult tradition does not recognize this distinction: Words are treated as if they are equivalent to things and can be substituted for them.  Manipulate the one and you manipulate the other.  Analogies, instead of being, as they are in the scientific tradition, explanatory devices subordinate to argument and proof, or heuristic tools to make models that can be tested, corrected, and abandoned if necessary, are, instead, modes of conceiving relationships in the universe that reify, rigidify, and ultimately come to dominate thought.  One no longer uses analogies: One is used by them.  They become the only way in which one can think or experience the world."  (Brian Vickers, "Analogy versus identity: the rejection of occult symbolism, 1580-1680", in Occult and scientific mentalities in the Renaissance, 1984, p. 95.)

         80.  Vickers considers such exemplars of occult attitudes toward language as Boehme, Ficino, Agrippa, Paracelsus, Comenius and John Webster, and  critics (as least by implication) of such attitudes like Francis Bacon, Galileo, Seth Ward, John Wilkins, Daniel Sennert, Johann Van Helmont, Robert Boyle and John Locke.  For example, there is Galileo's remark in "The Assayer" (Il Saggiatore, 1623), addressed to Lothario Sarsi, a pseudonymn of a Jesuit priest, Horatio Grassi:  "I am not so sure that in order to make a comet a quasi-planet, and as such to deck it out in the attributes of other planets, it is sufficient for Sarsi or his teacher to regard it as one and so name it.  If their opinions and their voices have the power of calling into existence the things they name, then I beg them to do me the favor of naming a lot of old hardware I have about my house, "gold."  (Galileo, "The Assayer" (Il Saggiatore), 1623, in Discoveries and Opinions of Galileo, 1957, translations and notes by Stillman Drake.)  Later in the same work, we find:  "To excite in us tastes, odors, and sounds I believe that nothing is required in external bodies except shapes, numbers, and slow or rapid movements.  I think that if ears, tongues, and noses were removed, shapes and numbers and motions would remain, but not odors or tastes or sounds.  The latter, I believe, are nothing more than names when separated from living beings, just as tickling and titillation are nothing but names in the absence of such things as noses and armpits."  (Galileo, ibid., p. 277.)

         81.  Isaac Newton had similar views.  In a letter to Richard Bentley of 25 February 1692/1693, he complains about a statement of Bentley's "representing it as absurd as that there should be positively an infinite arithmetical summ or number wch is a contradiction in terminis: but you do not prove it as absurd.  Neither do you prove that what men mean by an infinite summ or number is a contradiction in nature.  For a contradiction in terminis argues nothing more then an improperty of speech.  Those things wch men understand by improper and contradictious phrases may be sometimes really in nature wthout any contradiction at all.  A silver inkhorn a paper Lanthorn an iron whetstone are absurd phrases & yet ye things signified are really in nature."  (The Correspondence of Isaac Newton, edited by H. W. Turnbull, v. 3, 1961, p. 254.)

         82.  Vickers also refers to the controversy between Kepler and Fludd.  Kepler's attitude toward analogy is illustrated by a quotation from a letter of Kepler to Maestlin of 1605:  "Every planetary body must be regarded as being magnetic, or quasi-magnetic; in fact, I suggest a similarity, and do not declare an identity." (Koyré, loc. cit., p. 252.)  In short, Kepler understood the limitations of mathematical models.

         83.  Vickers quotes a 1968 Malinowski lecture of S. J. Tambiah, "The Magical Power of Words", concerning the effect of "sacred words" which are "thought to possess a special kind of power not normally associated with ordinary language", derived from the widespread "ancient belief in the creative power of the word".  Examples are found in the Vedic hymns of the Hindus, in certain Buddhist doctrines, in the Iranian Parsi religion, in the religions of the ancient Sumerians, Egyptians and Semites who believed that the world and its objects were created by the word of God, and among the Greeks whose doctrine concerning logos postulated that the essence of things lies in their names.  In the Bible, for example, we find:  "So shall my word be that goeth forth out of my mouth; it shall not reutrn unto me void, but it shall accomplish that which I please." (Isaiah 55:11).

         84.  In fact, the 3rd verse of the first book of Genesis reads in the Revised Standard Version:  "God said let there be light."   --"God said let there be light."  A little later, in Genesis 2.19-20, it is said of the first man Adam: "So out of the ground the Lord God formed every beast of the field and every bird of the air, and brought them to the man to see what he would call them; and whatever the man called every living creature, that was its name.  The man gave names to all cattle, and to the birds of the air, and to every beast of the field..... "  In the Christian Gospel of John, we have "in the beginning was the Word" and "the Word was God" and "the Word made flesh".  Here "Word" is a translation of logos, whose meaning is rather elastic, but which many agree in _this_ context refers to the "word of God" as understood in the Old Testament.  Perhaps John also intended the word to carry its connotation of reason, and of order, as opposed to chaos.  In any case, a great many Jewish, Muslim and Christian commentators stress the fact that God created by speaking.  Occasionally, a commentator will say that it is as if God created by commanding orally, so creation would be analogous to language acts.  But many hold that God's acts of creation, as described in Genesis, were language acts.  As a consequence, they regard language as a most powerful and holy instrument.  God gave this gift to Adam and, it is said, when God let Adam name the creatures, he gave them dominion -- power -- over them.

         85.  Questions of divinity aside, language is, of course, a most powerful instrument.  Who would deny the power of command, promise, entreaty, description, lying, literature, and all the other effective acts of language?  In Plato's Cratylus, Socrates calls Pan the declarer and mover of all things, and says he is speech, or the brother of speech.  Who can conceive of human society, civilization, culture, not founded on the motive power of language?  But mover of all things?  Of the sun and planets, and the particles or waves or wavicles that compose them?

         86.  The limits of language are under constant review.  Suffice it here to quote two opposed points of view.  "Learning to speak," says Han-Georg Gadamer, "does not mean to use a preexistent tool for designating a world already somehow familiar to us; it means acquiring a familiarity and acquaintance with the world itself and how it confronts us.....  Language is not a delimited realm of the speakable, over against which other realms that are unspeakable might stand.  Rather, language is all-encompassing.  There is nothing that is fundamentally excluded from being said, to the extent that our act of meaning intends it."  (Hans-Georg Gadamer, "Man and Language" (1966), in Philosophical Hermeneutics, 1976, p. 63, 67, translated by David Linge from Gadamer's Kleine Schriften).      

         87.  Contrarily, Alfred North Whitehead says:  "Language was developed in response to the excitements of practical actions.  It is concerned with the prominent facts.....  But the prominent facts are the superficial facts.....  There are other elements in our experience, on the fringe of consciousness, and yet massively qualifying our experience.....  Language is incomplete and fragmentary, and merely registers a stage in the average advance beyond ape-mentality.  But all men enjoy flashes of insight beyond meanings already stabilized in etymology and grammar.  Hence the rôle of literature, the rôle of the special sciences, and the rôle of philosophy: -- in their various ways engaged in finding expressions for meanings as yet unexpressed."  (Alfred North Whitehead, Adventures in Ideas, 1933, p. 166-167, p. 227-228.) 

         88.  Kepler made the point that naming a sign of the zodiac Scorpio after a tenuous resemblance of a constellation to a scorpion does not give the sign, or planets in the sign, any capacity to instill in humans any of the characteristics of scorpions.  This is a false conclusion based on an invalid analogy.  But Kepler didn't reject the usefulness of analogy in general.  Alexandre Koyré observes that in Kepler's Astronomia nova, when Kepler was concerned with the nature of the force which causes the planets to revolve around the sun, he says we can only proceed by analogy with other more usual, better known emanations, notably light and magnetic force.  Kepler commented that if we proceed in this way, our knowledge of the motive force of the sun will be vague and incomplete.  But it gives some idea of the kind of reality we are dealing with.  (Koyré, ibid, p. 199.) 

         89.  Kepler's attitude toward analogy resembles to a degree (is analogous to!) Galileo's attitude toward idealization, about which Koyré‚ wrote so eloquently in his Études galiléennes.  Galileo conceived of bodies falling in vacuums, frictionless surfaces, undisturbed objects moving forever with  constant velocities equal to their initial velocities (in circles, to be sure), the orbits of cannonballs being perfect parabolas (just as the ancients had conceived of the paths of the stars as being perfect circles -- but the cannonballs are sublunary), simple pendulums being isochronous (a little off, but nearly right for small oscillations).  As we would say today, Galileo produced mathematical models for various physical states or processes, and such models capture only certain quantitative aspects of  phenomena.  Kepler was also much given to making geometric models, and he was especially fond of his exotic model of the solar system based on the regular and star-shaped polyhedra.

         90.  Neither Kepler's nor Galileo's models agreed exactly or completely with reality.  Mathematical models seldom do.  They are idealizations or abstractions, and, in the case of quantities conceived of as continuous, inevitably introduce some degree of approximation.  Galileo's treatise in which he founds the science of strength of materials contains drawings of unidealized wooden beams, with knots in the wood visible, and showing plants growing out of crevices in the stone wall in which the beam is anchored. (Galileo Galilei, Discorsi e dimostrazioni matematiche intorno  … due nuove scienze, 1638; the drawings are on p. 116 and 119 of the translation into English by Henry Crew and Alfonso de Salvio, Dialogues concerning Two New Sciences, 1914.)  Galileo's geometrical idealizations and abstractions obviously don't capture all the properties of such objects, but only certain essential properties -- essential for Galileo's purpose.

         91.  As for Kepler, he realized in the long run that his lovely model with inscriptions and circumscriptions of the regular solids in the planetary spheres didn't match reality, and that not even the introduction of the star-shaped semi-regular polyhedra would give an exact model.  But the model served to guide him to the discovery of his three planetary laws, which have endured.  They too, however, apply only to idealized systems, such as the pair consisting of one planet and the sun, with the sun fixed, in which the effects of other planets and objects are ignored.  And even here one often considers the planet and the sun as mere points, rather than extended bodies.  Thus the laws yield only good approximations to certain behavior of planets.  It isn't too easy to give a precise meaning to the "good" in "good approximations", but it is clear to many who compare the predictions of the laws with actual measurements that the approximations given by the laws are not subjective assignments of numbers to the phenomena: the laws can be used to estimate something which is happening outside their users. 

         92.  We have seen something of the gulf between number mysticism and applied mathematics.  Johannisson's assertion that the Hermetic tradition stressed "rationality in a mathematical sense" must not be taken as support for the contention that natural philosophers were led by Hermeticists to realize the place or importance of mathematics in such sciences as astronomy and physics.  People applying mathematics to nature on the whole have had to struggle against the influence of Hermeticists.  This judgement is not a new one.  For example, Robert Westman concludes in a study of the supposed contributions of Hermeticism to the Scientific Revolution:  "Kepler and Galileo provide specific criteria for allowing us to weight one theory above another in terms of their mathematical intelligibility and their empirical adequacy.  This the Hermeticists failed to do because they either separated mathematics from natural philosophy or could not see how they were connected or totally subordinated mathematical statements to physical ones.....  What significant physical and mathematical insights Bruno and other alleged Hermeticists arrived at came from their individual, creative intuitions, often under the influence of doctrines first formulated in medieval natural philosophy, and in spite of their adherence to Hermetic doctrines."  (Robert Westman, "Magical Reform and Astronomical Reform: The Yates Thesis Reconsidered", in Hermeticism and the Scientific Revolution, 1977, p. 71, his italics.)  

         93.  Johannisson also discusses the role of Freemasonry and Rosicrucianism in early modern science.  "The Rosicrucians," she says, "-- whether existing as an actual society or not -- integrated in their program an open view of the world and a rejection of the Church's authority together with a passionate belief in science as the way to progress."  (ibid.)  Their science was based on Hermeticism and Paracelsianism, and comprised chiefly magic, cabala and alchemy.  To these, Johannisson adds "mathematics, physics, cosmology, and a medicine that stressed humanitarian ends."  However, the mathematics and physics were more in the manner of Fludd than of Kepler, and show little trace of the tradition of Euclid, Apollonius, Archimedes or the quantitative natural philosophers of the Middle Ages who studied the motions of physical objects.

         94.  A number of the theses of Frances Yates, especially those having to do with Rosicrucianism have been toned done by most of her followers -- Johannisson, it seems, is one of the more faithful.  In 1979, Brian Vickers went so far as to argue at length that in her book The Rosicrucian Enlightenment, "Yate's proposed rewriting of Renaissance history is an edifice built not on sand but on air."  ("Frances Yates and the Writing of History", Journal of Modern History, v. 51, no. 2, 1979, p. 287-316.)  Still, Merkel and Debus say in 1988 that "there are few who would now dispute that, taken in context, the Rosicrucian tracts were of great concern to seventeenth-century scientists and physicians representing many schools of thought."  (ibid., "Introduction", p. 9.)

         95.  Newton wrote a few comments on a Hermetic tract, described by Betty Jo Teeter Dobbs ("Newton's Commentary on the Emerald Tablet of Hermes Trismegistus: Its Scientific and Theological Significance", 1988, in Hermeticism and the Renaissance, Intellectual History and the Occult in Early Modern Europe, 1988, based on a 1982 meeting, edited by Ingrid Merkel and Allen G. Debus, p. 182-191.)  Newton carried out extensive alchemical studies, which Dobbs treated in her book The Foundations of Newton's Alchemy, or "The Hunting of the Greene Lyon", 1975.  Alchemy is of an age and nature comparable to astrology, and connections between the two are ancient.  For example, the basic metals were associated with planets (as always, including the sun and moon), and astrological and alchemical significances of the planets and the metals were interwoven.      

         96.  The psychologist and psychoanalyst Carl Jung argued at length that much of the symbolism of such studies, especially of alchemy, arose from projections of changes of the personality of the investigators onto their material.  The older alchemy, according to Jung, never had as its central aim the investigation of the nature of matter and its combinations.  Such maneuvers as it undertook that we would be willing to today to admit as bona fide chemistry were secondary to the work of psychological transformation which was performed by way of alchemical operations.  In this view, only during the course of the 17th century did a kind of rationalistic and materialistic alchemy precipitate out of the older alchemy, by way of corpuscular and mechanical theories of matter, in which matter was conceived to be made of tiny particles moving according to regular patterns.

         97.  It should be kept in mind that in our concentration on the heavens, on astral religion and astrology, and later, on mathematical cosmology and the inititiation of celestial mechanics, we must guard against a distortion of the attitudes of the people who have pursued these subjects.  Although of course there were individual differences, such people were often also very interested in the transformations of matter on earth, and didn't always try to live with their heads above the lunar sphere.  Whatever the merit of Jung's theories about the psychological burden of alchemy, many natural philosophers were concerned with what we would call chemical reactions, although to be sure until the 17th century these were usually presented in a context of some four or five element theory (fire, air, earth, water, and "fifth essence" (quintessence or aether) inherited from antiquity.

         98.  During the late 16th and early 17th century in Europe there was a kind of flowering of alchemy, analogous to the flowering of astrology in that period.  Dobbs says:  "In their rejection of the pagan accounts of natural phenomena offered by Aristotle and Galen, Renaissance Hermeticists had come to emphasize anew the importance of the first chapter of the book of Genesis.  In Genesis was a divine account of the creation of the world, one which could not be disputed, and one which could lend itself to interpretation as a divine chemical separation.  If the act of creation itself was to be understood chemically, then all of nature was to be understood similarly.  In short, chemistry was the key to all nature, the key to all the macrocosmic-microcosmic relationships sought by Robert Fludd and others.  A study of chemistry was a study of God as He had Himself written out His word in the Book of Nature.  Such a study could only lead one closer to God and was conceived as having moral value as well as contributing to the better grasp of the workings of nature and to the providing of better medicines for the relief of man's illnesses."  (Dobbs, loc. cit., 1975, p. 61.)       

         99.  In the 17th century, it was a common assumption of the "corpuscularians" -- of whom Robert Boyle (1627-1691) is perhaps the most famous -- that everything natural is made of elementary corpuscles or particles, all made of the same kind of matter.  Dobbs says:  "The primitive particles might differ in figure and magnitude, as did the letters of the alphabet; larger units, like words, were formed by the combinations of the primitive particles in different orders, groups, and positions.  The alphabet analogy was quite commonly drawn upon to explain chemical changes.   Yet however the particles might differ in size, shape, and arrangement, they were all made from the same basic substance."  (Dobbs, ibid., p. 46.)  Thus we are tempted to make a link between Jewish kabbalism and the alphabetical notation of our own chemistry.  

         100.  Newton spent considerable time and effort on alchemy, but it remains difficult to say exactly how alchemy and Hermeticism influenced his work in mechanics.  J. E. McGuire has argued that "Newton's intellectual orientation embodies a framework of concepts that largely emerge from the Neoplatonism developed by his Cambridge contemporaries" and that "traditions of magic and alchemy did not play a significant role in shaping Newton's conception of nature."  Hermeticism played a limited role in Cambridge natural philosophy, he says, because the Cambridge Platonists sought a restoration of Neoplatonism, which they tried to legitimize by relating their writings to Christian Hermeticism.  "For a short time in the early 1690s," McGuire says, "Newton explicitly accepted this ideology, but, like his Cambridge contemporaries, he did not accept any specific Hermetic doctrines." (J. E. McGuire, "Neoplatonism and Active Principles:  Newton and the Corpus Hermeticum", in Hermeticism and the Scientific Revolution, 1977, p. 131-133.)

         101.  On the other hand, Richard Westfall argues:  "I am seeking the source of the Newtonian concept of forces of attraction and repulsion between particles of matter, the concept that fundamentally altered the prevailing philosophy of nature and ushered in the intellectual world of modern science,  I am offering the argument that alchemy, Newton's involvement in which a vast corpus of papers establishes, offered him a stimulus to consider concepts beyond the bare ontology of the mechanical philosophy.  It appears to me that the Newtonian concept of force embodies the enduring influence of alchemy upon his scientific thought."  (Richard Westfall, "Newton and alchemy", p. 330, in Occult and scientific mentalities in the Renaissance, 1984, p. 315-335.)  Westfall says he sees no necessary opposition between his views and McGuire's.  He takes McGuire to have shown that the Platonism of Newton's teachers at Cambridge, in which one finds a concept of "active principles", influenced Newton's conception of force.  Westfall agrees, and says that alchemy influenced Newton's conception of force, too.  He observes that: "... for every page in Newton's papers of direct reference to [the Cambridge Platonists] More and Cudworth there are well over a hundred on alchemy.  I cannot make those papers disappear."  (Westfall, ibid., p. 331.)

         102.  Dobbs, Westfall and others, have said that Newton's concept of force, one of the central and more mysterious concepts in Newton's mechanics (his theory of how pieces of matter behave), descended at least partly from his alchemical ideas.  There has been an enormous debate over the ontological status of Newton's forces.  Newton himself indicates at the beginning of his Principia that there are three kinds of forces: resistive force, or inertia; impressed force, which tends to change the state of a body from rest or uniform (constant velocity) motion, and of which he mentions the three kinds, from percussion, from pressure and centripetal; and attracting force, such as gravity (repelling force is not mentioned here, although presumably a centripetal force might be interpreted as repelling -- Newton does speak of repelling forces elsewhere in the Principia.)  (Isaac Newton, Philosophiae naturalis principia mathematica (MathematicalPrinciples of Natural Philosophy), familiarly known as the Principia, 1687, Motte's translation revised by Cajori, 1934, p. 2.)  Procedures for quantitatively measuring forces are provided by Newton's three laws of motion (ibid., p. 13; see Appendix to this chapter), especially the second law which, in our terms, asserts that a force on body is to be measured by the rate of change in momentum of the body it produces, where the momentum of a body is to be found by measuring the mass and velocity of the body, and multiplying these together (Newton's definition, ibid., p. 1).  Thus, in the case of a mass constant in time, a quantity of force acting on a body is proportional to the acceleration of the body, the rate at which its velocity changes.

         103.  The question has often been asked, do Newton's definitions and axioms constitute a definition of force?  Is "force" just a word we use for rates of changes of momentum, or is there something in addition to this which constitutes the force, a "power" or "cause" or "activity"?  (See, for example, Ernst Nagel, The Structure of Science, 1961, Chapter 7, esp. p. 186-192.)  A number of physicists and philosophers have taken the attitude that Newton's statements should be interpreted as defining the word "force", and felt that to postulate any additional underlying properties would be to introduce non-existent or useless or nonsensical "metaphysical" principles.  The only way we know a force to be present, in this view, is to make physical measurements, and interpret them according to Newton's laws.  For a fixed mass, if an acceleration is found by measurement, then a force has acted, and not otherwise.

         104.  In the earlier years of the debate, beginning in Newton's own lifetime, the word "occult" rather than "metaphysical" was often used.  Many natural philosophers, especially Descartes and his followers, wished to eliminate "occult properties" from physical science.  This indeed was one of the most revolutionary aspects of the Cartesian philosophy, and one which goes a long way toward explaining its enormous success in connection with physics, even though Descartes's detailed physical theories were often faulty, and also the considerable opposition it provoked among theologians, despite Descartes' care to avoid controversy with ecclesiatical authorities.  Descartes argued for a sharp separation between matter and spirit, and to a large extent reduced matter to mere extension, something amenable to mathematical description.  In the astrological, alchemical and theological contexts of the time, this must have seemed to some like an infusion of pure oxygen, and to others like an intrusion of poison gas.  In either case, it was not something philosophers could take lightly.

         105.  Descartes's views were not wholly agreeable to Newton and some of his teachers and followers for a number of both physical and theological reasons, and a considerable debate grew up around this question.  One of the reasons Newton wrote the Principia was to make a contribution to the overthrow of certain aspects of the Cartesian philosophy, as Euclid's motive in the Elements may have been to introduce people to the theory of regular polyhedra -- both works turned out to be monumentally more applicable.  Part of the continuing debate hinged on whether or not there are spiritual components of forces.  Questions like these were asked: are the planets held in their courses by continual divine action, or were they set in motion by divine action and left to run on their own, or were they set in motion by purely physical actions, or have they simply been running forever?

         106.  The arguments of later philosophers, especially a host of positivists from Comte to the present, over whether or not Newtonian forces can only be recognized by making physical measurements and seeing whether or not they satisfy Newton's laws leave out the way Newton arrived at the concept of force.  Some positivists have said about this, roughly speaking, that they are only interested in reconstructing mechanics on a sound logical basis, and not in how the discoveries were made.  A few years ago, there was much reference to the "context of discovery" versus the "context of verification".  It is certainly true that physicists have paid little serious attention to the astrological and alchemical background of classical mechanics, and seem in many ways to have been the better for it.  Still, we may enquire whether or not a knowledge of the background might lead to the re-introduction, suitable refined and modified, of some of the older notions which are excluded by a positivistic point of view.  Indeed, we may go further and ask whether or not many physicists still harbor and frequently make use of thoughts about forces and energy which go beyond measurements interpreted according to mathematical equations.  For one thing, with the advent of quantum mechanics, observers have catapulted back into a prominence which they formerly had.  If Carl Jung and his followers are right, one of the great differences between alchemy and chemistry as we know understand lies in the amount to which the minds and emotions of observers is present within the practice of alchemy itself, and absent from our practice of chemistry -- at least officially. 

         107.  The physicist Paul Davies starts his book The Forces of Nature, 1986:  "In daily life we see the activity of forces all around us.  The force of gravity guides the planets in their motion and raises the ocean tides.  Electrical forces display themselves in thunderstorms.  Mechanical forces drive our machines and our own bodies.  Everywhere we look, matter is subjected to forces of some sort, arising from a multitude of agencies ..... The world is full of objects -- people, planets, clouds, atoms, flowers -- and full of motion.  Things happen when moving objects act collectively.  How do objects know about each other?  How do they respond to the presence and activities of other objects? ..... Although uniform motion is natural and needs no explanation, changes in motion require the action of some external agency.  Because the state of uniform motion is regarded as natural, we say that when a body is disturbed from this state it is being forced.  The agencies which produce forced motion are called forces.  It is the action of forces which enriches the activity of our universe, and which enables different parts of the world to be aware of each other's existence.  Without forces, nothing could act on or influence anything else, and all the matter in the universe would disintegrate into its elementary constituents, each subatomic particle moving independently of all the others."  (Paul Davies, The Forces of Nature, 2nd edition, 1986, p. 1-2.)

         108.  Just so: agencies, actions, influences.  Davies goes on:  "The effect of a force on a material body is to bring about an acceleration.  This is described by Newton's second law.....  To determine how a body responds to a given force F, which may be varying from time to time and place to place in both magnitude and direction, it is necessary to solve [ F = ma ] for the position of the body."  (ibid., p. 3.)  The force is there before the acceleration, and before the equation, and it takes a brave philosopher to maintain this is only manner of speaking.    

         109.  The physicist James Trefil remarks that the Nobel laureate physicist Richard Feynman once said, in the witty way he had, that in pre-Newtonian theories of planetary motion, "you have to have angels following the planets along, flapping their wings to move them."  He added that in Newton's explanation, "the angels flapped their wings to push each planet toward the sun, rather than along its orbit."  (James Trefil, Reading the Mind of God, 1989, p. 8.)  I don't know if this was a pure joke, or if Feynman was revealing a knowledge of how theories of planetary motion actually developed.  We will see later that the theory that angels control the planets was a popular one in the middle ages.  For example, St. Thomas Aquinas held a version of it.

         110.  At one stage in his work, up through the 1670's, Newton postulated a kind of "universal subtle matter" or "aether", which could be used to explain the attractive force of gravity and other forces.  It was, so to speak, a kind of "unified field theory", or GTE (Grand Theory of Everything).  Newton never could quite make this theory work, but he didn't abandon the idea of a universal aether entirely.  In what appear to have been his last ruminations about the mechanism of the world, in the Queries at the end of his Opticks (4th edition, 1730), he speculates on a very thin, exceedingly "elastick and active" aetherial medium -- definitely not a fluid -- which conveys light and heat, and "pervades all Bodies", and is "(by its elastick force) expanded through all the Heavens", and can also be used to account for the mechanism of vision.  (Newton, Opticks, 1730, Dover edition, 1952, p. 339-406.)

         111.  Newton goes so far as to ask:  "Are not gross Bodies and Light convertible into one another, and may not Bodies receive much of their Activity from the Particles of Light which enter their Composition?" (ibid., p. 374.)  There is considerable speculation in the Queries on the nature of chemical interactions, based on a corpuscular theory of matter.  And in the very last sentence of the Opticks, he takes a swipe at astral religion:  "And no doubt, if the Worship of false Gods had not blinded the Heathen, their moral philosophy would have gone farther than to the four Cardinal Virtues; and instead of teaching the Transmigration of Souls and to worship the Sun and Moon, and dead Heroes, they would have taught us to worship our true Author and Benefactor, as their Ancestors did under the Government of Noah and his Sons before they corrupted themselves."  (ibid., p. 406.) 

         112.  While Newton failed to make his unified aether theory work in general, he certainly made his theory of forces work in the domains to which he applied them.  In Dobb's words:  "The universe lived again as Newton's thoughts swung on toward the Principia in the 1680's, for forces and active principles were everywhere.  Not only was there the attractive force of gravity binding the planets into a vibrant whole, there was also activity in the sub-structure of matter.  Gone, in Newton's mind, were the inert particles of Cartesian matter resting quiescently together between impacts.  In their place were structured corpuscles of increasing complexity, held together upon occasion by attractive forces of their own, but also capable upon other occasions of repelling each other.  Change was the order of the day in the little world and matter matured and decayed and was constantly replenished by active principles."  (Dobbs, ibid., p. 212.)  Newton's universe did not run like a clock.  An untellable number of writers have referred to Newton's system of the world as a clockwork or machine-like universe, but as far as Newton himself is concerned -- aside from various of his followers -- the accusation is not just.  It might be better attributed to Descartes or even Leibniz, with whom Newton was frequently at odds.

         113.  In his Introduction to the Principia, Newton defines rational mechanics (as distinguished from practical mechanics) to be "the science of motions resulting from any forces whatever, and of the forces required to produce any motions, accurately proposed and demonstrated."  He offers his work as "the mathematical principles of philosophy", and says that this philosophy consists in this -- "from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena; and to this end the general propositions in the first and second Books are directed."  Newton continues:  "In the third book I give an example of this in the explication of the System of the World; for by the propositions mathematically demonstrated in the former Books, in the third I derive from celestial phenomena the forces of gravity with which bodies tend to the sun and several planets.  Then from these forces, by other propositions which are also mathematical, I deduce the motions of the planets, the comets, the moon, and the sea.  I wish we could derive the rest of the phenomena of Nature by the same kind of reasoning from mechanical principles, for I am induced by many reasons to suspect that they may all depend upon certain forces by which the particles of bodies, by some causes hitherto unknown, are either mutually impelled towards one another, and cohere in regular figures, or are repelled and recede from one another.  These forces being unknown, philosophers have hitherto attempted the seach of Nature in vain; but I hope the principles here laid down will afford some light either to this or some truer method of philosophy."  (Newton, ibid., p. xvii-xviii.)  It appears from this that he had even greater goals in mind than those he achieved in the Principia, and that the Queries in the Opticks are as close as he came to reaching them.  Do you suppose Newton thought he had failed in what he wanted to do?

 

 

         114.  Paul Davies wrote a second version of his The Forces of Nature, he says, to take account of new theories that there is a single "superforce" in which all forces have their origin.  (Davies, ibid., p. vii.)  There has been great hope among certain physicists that a GUT (Grand Unified Theory) of this kind will be generally accepted in the near future.  But even if this doesn't come to pass, the success that Newton had with his forces remains, suitably altered to meet the demands of relativity and

quantum theory.

     

     

         115.  James Trefil begins his book Reading the Mind of God  "This book is about an idea, one of the most astonishing and least appreciated ideas in modern science.  I call it the principle of universality.  It says that the laws of nature we discover here and now in our laboratories are true everywhere in the universe and have been in force for all time."  (James Trefil, Reading the Mind of God, 1989, p. 1.)  Trefil goes on to say that has found in lecturing to a wide variety of audiences that those not made up of university scientists give evidence of not knowing about this kind of universality.  His explanation is:  "The principle of universality is so important that it is never explicitly taught.  We [scientists] learn about it almost by osmosis.  It pervades our work, particularly in fields like astronomy, but is seldom explicitly stated."  (ibid., p. 2.)  If Trefil is right, many people even today assume unless taught otherwise that celestial objects play according to different rules than material things on earth.

     

     

         116.  This doesn't, though, in itself exclude theories in which angels control planets, unless angelic control is confined to a kind of perfect celestial matter, different in kind from terrestrial matter.  One need only extend angelic control to everything that moves.  Furthermore, Newton's idea of universality had precedents.  Some of the Stoics, for example, believed that the universe, the Divine Mind and ordinary matter everywhere, is made of one kind of stuff, such as Chrysippus's pneuma, and they had the idea that Fate rules the world with the orderliness of the heavens, akin to the idea that there are natural laws which are the same throughout the physical world.  Some of the pre-Socratic philosophers of Greece had ideas of the same genre, concerning elements or atoms, and logos or cosmos.  A number of them had systems in which there was more than one kind of stuff, but most of these postulated the same several kinds of stuff everywhere.  There were also the long-lived theories, popular among astrologers and poets, of man, a microcosm, correlated with the universe, the macrocosm.  All of these are kinds of physical universality.

     

     

         117.  What was different about Newton's kind of universality?  Newton had a concept of momentum, which can be very simply measured by multiplying inertial mass times velocity, and a concept of force as a rate at which momentum is changed.  And he had a mathematical technique, the calculus, which could be used, in some important cases, to find mathematical expressions for determining the motion of a body when mathematical expressions for the forces acting on the body are known.  His law of gravity gave an expression for one force, the inverse square expression for gravity.  That there is something reasonable about the way matter moves was not a novel idea in the time of Newton, nor was the idea that there are quantitative expressions describing such motions, nor was the idea that matter is made of the same kind of stuff everywhere.  But who would have thought, until Newton, that a program for deriving mathematical expressions giving the successive of moving objects could be laid down with three such simple laws, stateable in three sentences?  Such a simple program!  Alas, finding expressions for all the relevant forces acting on an object is seldom easy and probably sometimes impossible, and even when such expressions have been found, carrying out the program has turned out in many important cases to be mathematically very difficult, and most likely sometimes impossible in any deterministic or at least determinable (or, as some say, computable) way.  But when Newton's method works, it works like magic!
