Astronomy and astrology.

William offers a rather novel and unusual explanation of the difference in meaning between the terms “astronomy” and “astrology,” stating that authorities on the subject speak of the superior bodies in three ways, the fabulous, the astrological, and the astronomical. The method by fable is that employed by Aratus, Memroth (Nimrod the astronomer?), and Hyginus (“Eginus”), who interpret the Greek myths in an astronomical sense. Hipparchus and Martianus Capella are representatives of the astrological method, which treats of phenomena as they appear to exist in the heavens, whether they are really so or not. Astronomy, on the contrary, deals with things as they are, whether they seem to be so or not. Exactly what he has in mind by this distinction William fails to make any clearer as he proceeds, but from the fact that he lists Julius Firmicus and Ptolemy as instances of the astronomical method it would appear that he included part at least of what we should call astrology under “astronomy.” William cites yet other astronomical authorities, advising anyone wishing to learn about the Milky Way to read Macrobius, and for an explanation of the signs of the zodiac to consult Helpericus (of Auxerre), the ninth century compiler of a Computus which occurs with fair frequency in the manuscripts.[140]

Extent of the influence of the stars.

William represents “Plato, most learned of all philosophers,” as saying that God the Creator entrusted the task of forming the human body to the stars and spirits which He had first created, but reserved to Himself the making of the human soul.[141] This Christian interpretation or rather perversion of Plato’s doctrine in the Timaeus is characteristic. William accepts to the full the control of the stars over nature and the human body, but stops there. Like Adelard he states that the stars are composed of the same four elements as earthly objects. The predominance in their composition of the superior elements, fire and air, accounts for their motion. Their motion heats the atmosphere which in turn heats the element water, which is the fundamental constituent in the various species of animals, which further differ according to the admixture in them of the other elements. Of the superior elements the birds of the air have the most, and fish next. Of land animals choleric ones, like the lion, possess most fire; phlegmatic ones, like pigs, most water; and melancholic ones, like the cow and ass, most earth. The human body is composed of an unusual harmony of the four elements, to which Scripture alludes in saying that “God formed man of the dust of the earth.”[142] William also lists the natural qualities and humors of each planet and its consequent influence for good or evil. He believes that the ancient astrologi discovered that Saturn is a cold star by repeatedly observing that in those years when the Sun in Cancer burned the earth less than usual, Saturn was invariably in conjunction with it in the same sign. How Saturn comes to exert this chilling influence William is less certain. He has already denied the existence of the congealed waters above the firmament, so that he cannot accept the theory that Saturn is cold because of its proximity to them. He can only suggest that its great distance from us perhaps explains why it heats less than the other planets.[143] The good and evil influences of the planets also come out in the astrological interpretation of myth and fable. Thus Saturn is said to carry a scythe because one who carries a scythe does more execution in receding than in advancing. Jupiter is said in the fables to have ousted his father Saturn because the approach of the planet Jupiter increases the evil influence of Saturn. Jupiter is said to have begotten divers children in adultery because the conjunctions of that planet produce varied effects upon earth; and Venus is said to have had adulterous intercourse with Mars because the propinquity of the planet Venus to the planet Mars renders the former less benevolent. Mars is god of battle because the planet of that name produces heat and drought which in their turn engender animosity.[144] As the tides follow the phases of the moon, so, William believes, a universal flood or conflagration may be produced by the simultaneous elevation or depression of all the planets.[145] But he accepts comets as special signs of the future caused by the Creator’s will instead of attempting to give a natural explanation of the events which follow them.[146] This is perhaps because of their signifying human events. Thunder and lightning are discussed without mention of divination from them.[147]

Science and religion.

Thus far we have heard William cite authorities rather than spurn them as Adelard did. He could, however, be independent enough on occasion. He went so far as to reject the Scriptural account of waters above the firmament, if that word were taken in its ordinary astronomical sense, as naturally impossible; he explained away the passage in Genesis by interpreting the firmament to mean the air, and the waters above it, the clouds.[148] Like Adelard, too, he several times feels it essential to justify his views against the possible criticism of an obscurantist religious party. Discussing the Trinity, he insists that if anyone finds something in his book which is not found elsewhere, it should not on that account be stigmatized as heresy but only if it can be shown to be against the Faith.[149] Thus he confirms Adelard’s complaint that the present generation is prejudiced against any modern discoveries. William, by the way, also employs the word “modern.” Again, in affirming the physical impossibility of reconciling the elements fire and earth, he notes that someone may object that God could find a way. To this he replies that “we do not place a limit upon divine power, but we do say that of existing things none can do it, nor in the nature of things can there be anything that would suffice.”[150] In a third passage his indignation is fanned to a white heat by those who say, “We do not know how this is, but we know that God can do it.” “You poor fools,” he retorts, “God can make a cow out of a tree, but has He ever done so? Therefore show some reason why a thing is so, or cease to hold that it is so.”[151] Elsewhere he yet further dilates upon the unreasonableness of the opponents of natural science, who are loath to have explained even the natural facts given in the Bible but prefer to accept them blindly, and who, “since they themselves are unacquainted with the forces of nature, in order that they may have all men as companions in their ignorance, wish them to investigate nothing but to believe like rustics. We, on the contrary,” continues William, “think that a reason should be sought in every case, if one can be found.”[152] Thus he vigorously echoes Adelard’s exhortation to give and take reason, and his retort to the nephew’s suggestion that the growth of plants from earth can be explained only as a divine miracle.

Letter of William of St. Thierry to St. Bernard.

William, it turned out, was too original and bold in some of his assertions concerning the Trinity and kindred topics, which were not allowed to pass unchallenged. A letter to St. Bernard from William, abbot of St. Thierry,[153] shows the attitude of William of Conches’ opponents. The abbot first says,—with the assumption of superior seriousness and dignity characteristic through all time of conservatives, bigots, and pompous persons subconsciously aware of their own stupidity—that anyone who knows William of Conches personally is aware of his levity and will not take his vanities too seriously, and that he is to be classed with Abelard in the presumptuousness of his opinions. The abbot then devotes most of his letter to an attack upon William’s discussion of the Trinity, taking umbrage at his discussing questions of faith at all, especially upon a philosophical basis, and at his distribution of the three faculties, power, will, and wisdom, among the Three Persons. The abbot more briefly objects to William’s physical account of the creation of man, saying: “First he says that man’s body was not made by God but by nature, and the soul was given him by God afterwards, and forsooth that the body was made by spirits whom he calls demons and by the stars.” This doctrine the abbot regards as on the one hand dangerously close to the opinion “of certain stupid philosophers who say that there is nothing but matter and the material, and that there is no other God in the world than the concourse of the elements and the system of nature”; and on the other hand as manifestly Manichean, affirming that the human soul is created by a good God but the body by the prince of darkness. Finally the abbot complains that William “stupidly and haughtily ridicules history of divine authority,” and “interprets in a physical sense” the account of the creation of woman from one of Adam’s ribs.

Extent of William’s retraction in the Dragmaticon.

The effect of this theological attack upon William of Conches can probably be discerned in the Dragmaticon. There he states that it is his purpose to include “many essential points” which were not contained in the earlier treatise, and to omit those statements which he has since become convinced are erroneous. He then proceeds to list and expressly condemn certain statements in the earlier work as contrary to the Catholic Faith, and he asks those readers who have copies of that treatise to make these corrections in it.[154] He accordingly retracts his assertion that in the Trinity the Father represents power and the Holy Spirit will, since there is no direct scriptural authority for this view, but he still maintains that the Son is Wisdom on the authority of the Apostle. He takes back his interpretation of the words of the Prophet concerning Christ, “Who will tell his generation?” as indicating merely the difficulty and not the impossibility of solving that mystery. Finally he reverts to the letter of Scripture in regard to the creation of Eve.
