Part 41 (1/2)

Heat, light, magnetism, electricity, projectiles, digestion, and the incompressibility of water were studied by the right method and with results that enriched the world.

The academy was a fortress of science, and siege was soon laid to it. The votaries of scholastic learning denounced it as irreligious, quarrels were fomented, Leopold was bribed with a cardinal's hat and drawn away to Rome, and, after ten years of beleaguering, the fortress fell: Borelli was left a beggar; Oliva killed himself in despair.

So, too, the noted Academy of the Lincei at times incurred the ill will of the papacy by the very fact that it included thoughtful investigators. It was ”patronized” by Pope Urban VIII in such manner as to paralyze it, and it was afterward vexed by Pope Gregory XVI. Even in our own time sessions of scientific a.s.sociations were discouraged and thwarted by as kindly a pontiff as Pius IX.(276)

(276) For Porta, see the English translation of his main summary, Natural Magick, London, 1658. The first chapters are especially interesting, as showing what the word ”magic” had come to mean in the mind of a man in whom mediaeval and modern ideas were curiously mixed; see also Hoefer, Histoire de la Chimie, vol. ii, pp. 102-106; also Kopp; also Sprengel, Histoire de la Medecine, vol. iii, p. 239; also Musset-Pathay. For the Accademia del Cimento, see Napier, Florentine History, vol. v, p. 485; Tiraboschi, Storia della Litteratura; Henri Martin, Histoire de France; Jevons, Principles of Science, vol. ii, pp. 36-40. For value attached to Borelli's investigations by Newton and Huygens, see Brewster's Life of Sir Isaac Newton, London, 1875, pp. 128, 129. Libri, in his first Essai sur Galilee, p. 37, says that Oliva was summoned to Rome and so tortured by the Inquisition that, to escape further cruelty, he ended his life by throwing himself from a window.

For interference by Pope Gregory XVI with the Academy of the Lincei, and with public instruction generally, see Carutti, Storia della Accademia dei Lincei, p. 126. Pius IX, with all his geniality, seems to have allowed his hostility to voluntary a.s.sociations to carry him very far at times. For his answer to an application made through Lord Odo Russell regarding a society for the prevention of cruelty to animals and his answer that ”such an a.s.sociation could not be sanctioned by the Holy See, being founded on a theological error, to wit, that Christians owed any duties to animals,” see Frances Power Cobbe, Hopes of the Human Race, p. 207.

A hostility similar in kind, though less in degree, was shown in Protestant countries.

Even after Thomasius in Germany and Voltaire in France and Beccaria in Italy had given final blows to the belief in magic and witchcraft throughout Christendom, the traditional orthodox distrust of the physical sciences continued for a long time.

In England a marked dislike was shown among various leading ecclesiastics and theologians towards the Royal Society, and later toward the a.s.sociation for the Advancement of Science; and this dislike, as will hereafter be seen, sometimes took shape in serious opposition.

As a rule, both in Protestant and Catholic countries instruction in chemistry and physics was for a long time discouraged by Church authorities; and, when its suppression was no longer possible, great pains were taken to subordinate it to instruction supposed to be more fully in accordance with the older methods of theological reasoning.

I have now presented in outline the more direct and open struggle of the physical sciences with theology, mainly as an exterior foe. We will next consider their warfare with the same foe in its more subtle form, mainly as a vitiating and sterilizing principle in science itself.

We have seen thus far, first, how such men as Eusebius, Lactantius, and their compeers, opposed scientific investigation as futile; next, how such men as Albert the Great, St. Thomas Aquinas, and the mult.i.tude who followed them, turned the main current of medieval thought from science to theology; and, finally, how a long line of Church authorities from Popes John XXII and Innocent VIII, and the heads of the great religious orders, down to various theologians and ecclesiastics, Catholic and Protestant, of a very recent period, endeavoured first to crush and afterward to discourage scientific research as dangerous.

Yet, injurious as all this was to the evolution of science, there was developed something in many respects more destructive; and this was the influence of mystic theology, penetrating, permeating, vitiating, sterilizing nearly every branch of science for hundreds of years. Among the forms taken by this development in the earlier Middle Ages we find a mixture of physical science with a pseudo-science obtained from texts of Scripture. In compounding this mixture, Jews and Christians vied with each other. In this process the sacred books were used as a fetich; every word, every letter, being considered to have a divine and hidden meaning. By combining various scriptural letters in various abstruse ways, new words of prodigious significance in magic were obtained, and among them the great word embracing the seventy-two mystical names of G.o.d--the mighty word ”Schemhamphoras.” Why should men seek knowledge by observation and experiment in the book of Nature, when the book of Revelation, interpreted by the Kabbalah, opened such treasures to the ingenious believer?

So, too, we have ancient mystical theories of number which the theological spirit had made Christian, usurping an enormous place in medieval science. The sacred power of the number three was seen in the Trinity; in the three main divisions of the universe--the empyrean, the heavens, and the earth; in the three angelic hierarchies; in the three choirs of seraphim, cherubim, and thrones; in the three of dominions, virtues, and powers; in the three of princ.i.p.alities, archangels, and angels; in the three orders in the Church--bishops, priests, and deacons; in the three cla.s.ses--the baptized, the communicants, and the monks; in the three degrees of attainment--light, purity, and knowledge; in the three theological virtues--faith, hope, and charity--and in much else. All this was brought into a theologico-scientific relation, then and afterward, with the three dimensions of s.p.a.ce; with the three divisions of time--past, present, and future; with the three realms of the visible world--sky, earth, and sea; with the three const.i.tuents of man--body, soul, and spirit; with the threefold enemies of man--the world, the flesh, and the devil; with the three kingdoms in nature--mineral, vegetable, and animal; with ”the three colours”--red, yellow, and blue; with ”the three eyes of the honey-bee”--and with a mult.i.tude of other a.n.a.logues equally precious. The sacred power of the number seven was seen in the seven golden candlesticks and the seven churches in the Apocalypse; in the seven cardinal virtues and the seven deadly sins; in the seven liberal arts and the seven devilish arts, and, above all, in the seven sacraments. And as this proved in astrology that there could be only seven planets, so it proved in alchemy that there must be exactly seven metals. The twelve apostles were connected with the twelve signs in the zodiac, and with much in physical science.

The seventy-two disciples, the seventy-two interpreters of the Old Testament, the seventy-two mystical names of G.o.d, were connected with the alleged fact in anatomy that there were seventy-two joints in the human frame.

Then, also, there were revived such theologic and metaphysical subst.i.tutes for scientific thought as the declaration that the perfect line is a circle, and hence that the planets must move in absolute circles--a statement which led astronomy astray even when the great truths of the Copernican theory were well in sight; also, the declaration that nature abhors a vacuum--a statement which led physics astray until Torricelli made his experiments; also, the declaration that we see the lightning before we hear the thunder because ”sight is n.o.bler than hearing.”

In chemistry we have the same theologic tendency to magic, and, as a result, a muddle of science and theology, which from one point of view seems blasphemous and from another idiotic, but which none the less sterilized physical investigation for ages. That debased Platonism which had been such an important factor in the evolution of Christian theology from the earliest days of the Church continued its work. As everything in inorganic nature was supposed to have spiritual significance, the doctrines of the Trinity and Incarnation were turned into an argument in behalf of the philosopher's stone; arguments for the scheme of redemption and for transubstantiation suggested others of similar construction to prove the trans.m.u.tation of metals; the doctrine of the resurrection of the human body was by similar mystic jugglery connected with the processes of distillation and sublimation. Even after the Middle Ages were past, strong men seemed unable to break away from such reasoning as this--among them such leaders as Basil Valentine in the fifteenth century, Agricola in the sixteenth, and Van Helmont in the seventeenth.

The greatest theologians contributed to the welter of unreason from which this pseudo-science was developed. One question largely discussed was, whether at the Redemption it was necessary for G.o.d to take the human form. Thomas Aquinas answered that it was necessary, but William Occam and Duns Scotus answered that it was not; that G.o.d might have taken the form of a stone, or of a log, or of a beast. The possibilities opened to wild subst.i.tutes for science by this sort of reasoning were infinite. Men have often asked how it was that the Arabians accomplished so much in scientific discovery as compared with Christian investigators; but the answer is easy: the Arabians were comparatively free from these theologic allurements which in Christian Europe flickered in the air on all sides, luring men into paths which led no-whither.

Strong investigators, like Arnold of Villanova, Raymond Lully, Basil Valentine, Paracelsus, and their compeers, were thus drawn far out of the only paths which led to fruitful truths. In a work generally ascribed to the first of these, the student is told that in mixing his chemicals he must repeat the psalm Exsurge Domine, and that on certain chemical vessels must be placed the last words of Jesus on the cross.

Vincent of Beauvais insisted that, as the Bible declares that Noah, when five hundred years old, had children born to him, he must have possessed alchemical means of preserving life; and much later d.i.c.kinson insisted that the patriarchs generally must have owed their long lives to such means. It was loudly declared that the reality of the philosopher's stone was proved by the words of St. John in the Revelation. ”To him that overcometh I will give a white stone.” The reasonableness of seeking to develop gold out of the baser metals was for many generations based upon the doctrine of the resurrection of the physical body, which, though explicitly denied by St. Paul, had become a part of the creed of the Church. Martin Luther was especially drawn to believe in the alchemistic doctrine of trans.m.u.tation by this a.n.a.logy. The Bible was everywhere used, both among Protestants and Catholics, in support of these mystic adulterations of science, and one writer, as late as 1751, based his alchemistic arguments on more than a hundred pa.s.sages of Scripture. As an example of this sort of reasoning, we have a proof that the elect will preserve the philosopher's stone until the last judgment, drawn from a pa.s.sage in St. Paul's Epistle to the Corinthians, ”We have this treasure in earthen vessels.”

The greatest thinkers devoted themselves to adding new ingredients to this strange mixture of scientific and theologic thought. The Catholic philosophy of Thomas Aquinas, the Protestant mysticism of Jacob Boehme, and the alchemistic reveries of Basil Valentine were all cast into this seething ma.s.s.

And when alchemy in its old form had been discredited, we find scriptural arguments no less perverse, and even comical, used on the other side. As an example of this, just before the great discoveries by Stahl, we find the valuable scientific efforts of Becher opposed with the following syllogism: ”King Solomon, according to the Scriptures, possessed the united wisdom of heaven and earth; but King Solomon knew nothing about alchemy (or chemistry in the form it then took), and sent his vessels to Ophir to seek gold, and levied taxes upon his subjects; ergo alchemy (or chemistry) has no reality or truth.” And we find that Becher is absolutely turned away from his labours, and obliged to devote himself to proving that Solomon used more money than he possibly could have obtained from Ophir or his subjects, and therefore that he must have possessed a knowledge of chemical methods and the philosopher's stone as the result of them.(277)

As to the more rapid transition of light than sound, the following expresses the scholastic method well: ”What is the cause why we see sooner the lightning than we heare the thunder clappe? That is because our sight is both n.o.bler and sooner perceptive of its object than our eare; as being the more active part, and priore to our hearing: besides, the visible species are more subtile and less corporeal than the audible species.”--Person's Varieties, Meteors, p. 82.

Of the general reasoning enforced by theology regarding physical science, every age has shown examples; yet out of them all I will select but two, and these are given because they show how this mixture of theological with scientific ideas took hold upon the strongest supporters of better reasoning even after the power of medieval theology seemed broken.

The first of these examples is Melanchthon. He was the scholar of the Reformation, and justly won the t.i.tle ”Preceptor of Germany.” His mind was singularly open, his sympathies broad, and his usual freedom from bigotry drew down upon him that wrath of Protestant heresy-hunters which embittered the last years of his life and tortured him upon his deathbed. During his career at the University of Wittenberg he gave a course of lectures on physics, and in these he dwelt upon scriptural texts as affording scientific proofs, accepted the interference of the devil in physical phenomena as in other things, and applied the medieval method throughout his whole work.(278)
