A History of the Warfare of Science with Theology in Christendom

"As new explorations were made in various parts of the world, this danger to the theological view went on increasing. The sloths in South America suggested painful questions: How could animals so sluggish have got away from the neighborhood of Mount Ararat so completely and have traveled so far? The explorations in Australia and neighboring islands made matters still worse, for there was found... a whole realm of animals differing widely from those of other parts of the earth. ...for example, how to explain the fact that the kangaroo can have been in the ark and be now only found in Australia... and, if the theory were adopted that at some period a causeway extended across the vast chasm separating Australia from the nearest mainland, why did not lions, tigers, camels, and camelopards force or find their way across it?"

"First of those... beginning to develop again that current of Greek thought which the system drawn from our sacred books by the fathers and doctors of the Church had interrupted for more than a thousand years was Giordano Bruno."

"More and more it was seen that the number of different species was far greater than the world had hitherto imagined. Greater and greater had become the old difficulty in conceiving that, of these innumerable species, each had been specially created by the Almighty hand; that each had been brought before Adam by the Almighty to be named; and that each, in couples or in sevens, had been gathered by Noah into the ark."

"What was more embarrassing, the number of distinct species went on increasing rapidly, indeed enormously... Already there were premonitions of the strain made upon Scripture by requiring a hundred and sixty distinct miraculous interventions of the Creator to produce the hundred and sixty species of land shells found in the little island of Madeira alone, and fourteen hundred distinct interventions to produce the actual number of distinct species of a single well-known shell."

"We may note the opinion of St. Basil the Great in the fourth century. Discussing the work of creation, he declares that, at the command of God, "the waters were gifted with productive power"; from slime and muddy places frogs, flies, and gnats came into being"; and he finally declares that the same voice which gave this energy and quality of productiveness to earth and water shall be similarly efficacious until the end of the world. St. Gregory of Nyssa held a similar view. This idea of these great fathers of the Eastern Church took even stronger hold on the great father of the Western Church. For St. Augustine, so fettered usually by the letter of the sacred text, broke from his own famous doctrine as to the acceptance of Scripture and spurned the generally received belief of a creative process... In his great treatise [De Cenesi contra Manichæos] on Genesis he says: "To suppose that God formed man from the dust with bodily hands is very childish. ...God neither formed man with bodily hands nor did he breathe upon him with throat and lips.""

"At the close of the Middle Ages in spite of the devotion of the Reformed Church to the letter of Scripture the revival of learning and the great voyages gave an atmosphere in which better thinking on the problems of Nature began to gain strength. On all sides in every field men were making discoveries which caused the general theological view to appear more and more inadequate."

"These germs of a fruitful skepticism grew, and we find Dannhauer going a step further and declaring his even in the unicorn, insisting that it was a rhinoceros—only that and nothing more."

"Shortly before the middle of the nineteenth century the main movement culminated in the Bridge water Treatises. ...the President of the Royal Society selected eight persons... for writing and publishing a treatise on the "power, wisdom, and goodness of God, as manifested in the creation." ...It was a marked advance on all that had appeared before, in matter, method, and spirit. Looking back... now we can see that it was provisional, but that it was none the less fruitful in truth, and we may well remember Darwin's remark on the stimulating effect of mistaken theories, as compared with the sterilizing effect of mistaken observations: mistaken observations lead men astray, mistaken theories suggest true theories. An effort made in so noble a spirit certainly does not deserve the ridicule that, in our own day, has sometimes been lavished upon it. ...this is far from just to the conceptions of such men as Butler, Paley, and Chalmers, no matter how fully the thinking world has now outlived them."

"The first striking evidence of this new difficulty was shown by the eminent Jesuit missionary, Joseph Acosta. In his Natural and Moral History of the Indies published in 1590, he proved himself honest and lucid. Though entangled in most of the older scriptural views, he broke away from many; but the distribution of animals gave him great trouble. Having shown the futility of St Augustine's other explanations, he quaintly asks: "Who can imagine that in so long a voyage men woulde take the paines to carrie Foxes to Peru... Who woulde likewise say that they have carried Tygers and Lyons? Truly it were a thing worthy the laughing at to thinke so. It was sufficient yea very much for men driven against their willes by tempest in so long and unknowne a voyage to escape with their owne lives without busying themselves to carrie Woolves and Foxes and to nourish them at sea.""

"The great Linnaeus himself, in spite of his famous declaration favoring the fixity of species, had dealt a death blow to the old theory. In his Systema Naturæ, published in the middle of the eighteenth century, he had enumerated four thousand species of animals, and the difficulties involved in the naming of each of them by Adam and in bringing them together in the ark appeared to all thinking men more and more insurmountable."

"We have seen thus far, how there came into the thinking of mankind upon the visible universe and its inhabitants the idea of a creation virtually instantaneous and complete. ...But while this idea was thus developed... through thousands of years, another conception... equally ancient, was developed ...the conception of all living beings as wholly or in part the result of a growth process—of an evolution. This is clearly seen in those records of Chaldaeo-Babylonian thought... a watery chaos which under divine action, brings forth the earth and its inhabitants; first the sea animals and then the land animals ...there is placed over the whole creation a solid, concave firmament; in both, light is created first, and the heavenly bodies are afterward placed "for signs and for seasons"; in both, the number seven is especially sacred, giving rise to a sacred division of time ...followed by a legend regarding "the fall of man" and a deluge, many details of which clearly passed, in slightly modified form, from the Chaldean into the Hebrew accounts."

"There was still another ancient source of evolution ideas. Thoughtful men of the early civilizations... along the great rivers... noted how the sun-god, as he rose in his fullest might, caused the water and the rich soil to teem with the lesser forms of life. In Egypt, especially, men saw how under this divine power the Nile slime brought forth "creeping things innumerable." Hence mainly this ancient belief that the animals and man were produced by lifeless matter at the divine command, "in the beginning," was supplemented by the idea that some of the lesser animals, especially the insects, were produced by a later evolution, being evoked after the original creation from various sources, but chiefly from matter in a state of decay. This crude, early view aided doubtless in giving germs of a better evolution theory to the early Greeks. Anaximander, Empedocles, Anaxagoras, and greatest of all, Aristotle, as we have seen, developed them, making their way at times by guesses toward truths since established by observation. Aristotle especially, both by speculation and observation... reached something like the modern idea of a succession of higher organizations from lower, and made the fruitful suggestion of "a perfecting principle" in Nature. With the coming in of Christian theology this tendency toward a yet truer theory of evolution was mainly stopped, but the old crude view remained..."

"Theological necessity was among the main reasons which led St. Isidore of Seville, in the seventh century, to incorporate this theory [see preceding quote], supported by St. Basil and St. Augustine, into his great encyclopedic work [Etymologiae] which gave materials for thought on God and Nature to so many generations. He familiarized the theological world still further with the doctrine of secondary creation, giving such examples of it as that "bees are generated from decomposed veal, beetles from horseflesh, grasshoppers from mules, scorpions from crabs," and, in order to give still stronger force to the idea of such transformations, he dwells on the biblical account of Nebuchadnezzar, which appears to have taken strong hold upon medieval thought in science, and he declares that other human beings had been changed into animals, especially into swine, wolves, and owls."

"Biblical theology continued to spin its own webs out of its own bowels, and all the lesser theological flies continued to be entangled in them; yet here and there stronger thinkers broke loose from this entanglement and helped somewhat to disentangle others."

"Near the end of the same [17th] century, Father Kircher, the great Jesuit professor at Rome, holds back the skeptical current, insists upon the orthodox view, and represents among the animals entering the ark sirens and griffins."

"Prof. [Georg Casper] Kirchmaier [1635-1700] at the University of Wittenberg, treats phoenix and basilisk alike as old wives' fables. As to the phoenix, he denies its existence, not only because Noah took no such bird into the ark, but also because, as he pithily remarks, "birds come from eggs, not from ashes." But the unicorn he can not resign, nor will he even concede that the unicorn is a rhinoceros; he appeals to Job and to Marco Polo to prove that this animal, as usually conceived, really exists, and says, "Who would not fear to deny the existence of the unicorn, since Holy Scripture names him with distinct praises?" As to the other great animals mentioned in Scripture, he is so rationalistic as to admit that behemoth was an elephant and leviathan a whale."

"This better method of interrogating Nature soon led to the formation of societies for the same purpose. In 1560 was founded an Academy for the Study of Nature at Naples, but theologians, becoming alarmed, suppressed it, and for nearly one hundred years there was no new combined effort of that sort, until in 1645 began the meetings in London of what was afterward the Royal Society. Then came the Academy of Sciences in France, and the Accademia del Cimento in Italy; others followed in all parts of the world, and a great new movement was begun."

"In the same seventeenth century... John Ray... produced a number of works on plants, fishes, and birds; but the most widely read of all was entitled The Wisdom of God manifested in the Works of Creation. ...Ray argued the goodness and wisdom of God from the adaptation of the animals not only to man's uses but to their own lives and surroundings."

"But the difficulties... were as nothing compared to those raised by the distribution of animals. Even in the first days of the Church this had aroused serious thought... St. Augustine... in his City of God he had stated the difficulty as follows: "But there is a question about all these kinds of beasts which are neither tamed by man nor spring from the earth... as to how they could find their way to the islands after that flood which destroyed every living thing not preserved in the ark. ...some islands are so remote from continental lands that it does not seem possible that any creature could reach them by swimming. ...and it cannot be denied that the transfer may have been accomplished through the agency of angels commanded or allowed to perform this labor by God.""

"This difficulty had now assumed a magnitude of which St. Augustine never dreamed. Most powerful of all agencies to increase it were the voyages of Columbus, Vasco da Gama, Magellan, Amerigo Vespucci, and other navigators of the period of discovery. Still more serious did it become as the great islands of the southern seas were explored. Every navigator brought home tidings of new species of animals and of races of men living in parts of the world where the theologians, relying on the statement of St. Paul that the gospel had gone into all lands, had for ages declared there could be none; until finally it overtaxed even the theological imagination to conceive of angels, in obedience to the divine command, distributing the various animals over the earth, dropping the megatherium in South America, the archeopteryx in Europe, the ornithorhynchus in Australia, and the opossum in North America."

"In 1667 Abraham Milius published at Geneva his book on The Origin of Animals and the Migrations of Peoples This book shows like that of Acosta the shock and strain to which the discovery of America subjected the received theological scheme of things. ...Milius especially grapples is the distribution of animals. ...he asks, "What of the beasts which neither fly nor swim?" ...As to fishes he says, "They are very averse to wandering from their native waters." ...he asks: "Who would like to get different sorts of lions, bears, tigers, and other ferocious and noxious creatures on board ship? Who would trust himself with them, and who would wish to plant colonies of such creatures in new desirable lands?" His conclusion is that plants and animals take their origin in the lands wherein they are found; an opinion which he supports by quoting from the two narrations in Genesis passages which imply generative force in earth and water."

"Eminent Benedictine, Dom Calmet, in his Commentary, expressed the belief that all the species of a genus had originally formed one species, and he dwelt on this view as one which enabled him to explain the possibility of gathering all animals into the ark. This idea, dangerous as it was to the fabric of orthodoxy, and involving a profound separation from the general doctrine of the Church, seems to have been abroad among thinking men, for we find in the latter half of the same century even Linnaeus inclining to consider it."

"By the middle of the nineteenth century the whole theological theory of creation—though still preached everywhere as a matter of form—was clearly seen by all thinking men to be hopelessly lost: such strong men as Cardinal Wiseman in the Roman Church, Dean Buckland in the Anglican, and Hugh Miller in the Scottish Church, made heroic efforts to save something from it, but all to no purpose. Neither the powerful logic of Bishop Butler nor the nimble reasoning of Archdeacon Paley availed."

"Just as the line of astronomical thinkers from Copernicus to Newton had destroyed the old astronomy, in which the earth was the center, and the Almighty sitting above the firmament the agent in moving the heavenly bodies about it with his own hands, so now a race of biological thinkers had destroyed the old idea of a Creator minutely contriving and fashioning all animals to suit the needs and purposes of man."

"Since the researches of Layard, George Smith, Oppert, Schrader, [Peter] Jensen, Sayce, and their compeers, there is no longer a reasonable doubt that this ancient view of the world, elaborated if not originated in that earlier civilization, came thence as a legacy to the Hebrews..."

"The Rev. Prof. Sayce, of Oxford.. has recently declared his belief that the Chaldaeo-Babylonian theory was the undoubted source of the similar theory propounded by the Ionic philosopher Anaximander—the Greek thinkers deriving this view from the Babylonians through the Phoenicians; he also allows that from the same source its main features were adopted into both the accounts given in the first of our sacred books, and... the most eminent Christian Assyriologists concur."

"St. Augustine... suggests the adoption of the old emanation or evolution theory, [and] shows that "certain very small animals may not have been created on the fifth and sixth days, but may have originated later from putrefying matter," argues that, even if this be so, God is still their creator, dwells upon such a potential creation as involved in the actual creation, and speaks of animals "whose numbers the after-time unfolded." In his great treatise [De Trinitate] on the Trinity... we find the full growth of this opinion. He develops at length the view that in the creation of living beings there was something I like a growth—that God is the ultimate author, but works through secondary causes; and finally argues that certain substances are endowed by God with the power of producing certain classes of plants and animals."

"More and more it became difficult to reconcile the dignity of the Almighty with his work in bringing each of these creatures before Adam to be named; or to reconcile the human limitations of Adam with his work in naming "every living creature"; or to reconcile the dimensions of Noah's ark with the space required for preserving all of them, and the food of all sorts necessary for their sustenance. ...Origen had dealt with it by suggesting that the cubit was six times greater than had been supposed. Bede explained Noah's ability to complete so large a vessel by supposing that he worked upon it during a hundred years. ...He also lessened the strain on faith still more by diminishing the number of animals taken into the ark—supporting his view upon Augustine's theory of the later development of insects out of carrion."

"In the twelfth century, Peter Lombard, in his theological summary, The Sentences, so powerful in molding the thought of the Church, emphasized the distinction between animals which spring from carrion and those which are created from earth and water; the former he holds to have been created "potentially," the latter "actually.""

"St. Thomas Aquinas...in the Summa, which remains the greatest work of medieval thought, accepts the idea that certain animals, spring from the decaying bodies of plants and animals, and declares that they are produced by the creative word of God either actually or virtually."

"Here and there among men who were free from church control we have work of a better sort. In the twelfth and thirteenth centuries Abd Allatif made observations upon the natural history of Egypt which showed a truly scientific spirit, and the Emperor Frederick II attempted to promote a more fruitful study of Nature; but one of these men was abhorred as a Mussulman and the other as an infidel."

"This general employment of natural science for pious purposes went on after the Reformation. Luther frequently made this use of it, and his example controlled his followers. In 1612, Wolfgang Franz, Professor of Theology at Luther's university, gave to the world his sacred history of animals, which went through many editions. It contained a very ingenious classification, describing "natural dragons," which have three rows of teeth to each jaw, and he piously adds, "the principal dragon is the Devil.""

"Yet even among theologians we note here and there a skeptical spirit in natural science. Early in the same seventeenth century [Par F.] Eugène Roger published his Travels in Palestine. As regards the utterances of Scripture he is soundly orthodox: he prefaces his work with a map showing... the place where Samson slew a thousand Philistines with the jawbone of an ass, the cavern which Adam and Eve inhabited after their expulsion from paradise, the spot where Balaam's ass spoke, the place where Jacob wrestled with the angel, the steep place down which the swine possessed of devils plunged into the sea, the position of the salt statue which was once Lot's wife, the place at sea where Jonah was swallowed by the whale, and "the exact spot where St. Peter caught one hundred and fifty three fishes." As to natural history he describes and discusses with great theological acuteness the basilisk. ...about a foot and a half long, is shaped like a crocodile, and kills people with a single glance. The one which he saw was dead fortunately for him, since in the time of Pope Leo IV—as he tells us—one appeared in Rome and killed many people by merely looking at them; but the Pope destroyed it with his prayers and the sign of the cross. ...Providence has wisely and mercifully protected man by requiring the monster to cry aloud two or three times whenever it leaves its den. ...the same divine mercy has provided that the crowing of a cock will kill the basilisk. Yet even in this good and credulous missionary we see the influence of Bacon and the dawn of experimental science; for, having been told many stories regarding the salamander, he secured one, placed it alive upon the burning coals, and reports to us that the legends concerning its power to live in the fire are untrue. He also tried experiments with the chameleon..."

"In the second half of the same [17th] century Hottinger in his Theological Examination of the History of Creation breaks from the belief in the phoenix; but his skepticism is care fully kept within the limits imposed by Scripture."

"Still the main current continued strongly theological. In 1712 Samuel Bochart published his great work upon the animals of Holy Scripture. ...Mixed up in the book, with the principal mass drawn from Scripture, were many facts and reasonings taken from investigations by naturalists; but all were permeated by the theological spirit."

"The inquiry into Nature having thus been pursued nearly two thousand years theologically, we find by the middle of the sixteenth century some promising beginnings of a different method—the method of inquiry into Nature scientifically—the method which seeks not plausibilities but facts. At that time Edward Wotton led the way in England and Conrad Gesner on the Continent, by observations widely extended, carefully noted, and thoughtfully classified."

"Fortunately, one thing prevented an open breach between theology and science: while new investigators had mainly given up the mediaeval method so dear to the Church, they had very generally retained the conception of direct creation and of design throughout creation—a design having as its main purpose the profit, instruction, enjoyment, and amusement of man. ...Science, while somewhat freed from its old limitations, became the handmaid of theology in illustrating the doctrine of creative design..."

"About the middle of the seventeenth century came a great victory of the scientific over the theologic method. At that time Francesco Redi published the results of his inquiries into the doctrine of spontaneous generation. For ages a widely accepted doctrine had been that water, filth, and carrion had received power from the Creator to generate worms, insects, and a multitude of the smaller animals; and this doctrine had been especially welcomed by St. Augustine and many of the fathers, since it relieved the Almighty of making, Adam of naming, and Noah of living in the ark with these innumerable despised species. But to this fallacy Redi put an end. ...he showed that every one of these animals came from an egg; each, therefore, must be the lineal descendant of an animal created, named, and preserved from "the beginning.""

"Herein lies the truth of all bibles, and especially of our own. ...they are eminently precious, not as a record of outward fact, but as a mirror of the evolving heart, mind, and soul of man. They are true because they have been developed in accordance with the laws governing the evolution of truth in human history, and because in poem, chronicle, code, legend, myth, apologue, or parable they reflect this development of what is best in the onward march of humanity. To say that they are not true is as if one should say that a flower or a tree or a planet is not true; to scoff at them is to scoff at the law of the universe. In welding together into noble form, whether in the book of Genesis, or in the Psalms, or in the book of Job, or elsewhere, the great conceptions of men acting under earlier inspiration, whether in Egypt, or Chaldea, or India, or Persia, the compilers of our sacred books have given to humanity a possession ever becoming more and more precious; and modern science, in substituting a new heaven and a new earth for the old—the reign of law for the reign of caprice, and the idea of evolution for that of creation..."

"At the Reformation the vast authority of Luther was thrown in favor of the literal acceptance of Scripture as the main source of natural science. The allegorical and mystical interpretations of earlier theologians he utterly rejected. ..."I hold that the animals took their being at once upon the word of God, as did also the fishes in the sea.""

"Not less explicit in his adherence to the literal account of creation given in Genesis was Calvin. He warns those who, by taking another view than his own, "basely insult the Creator, to expect a judge who will annihilate them." He insists that all species of animals were created in six days, each made up of an evening and a morning, and that no new species has ever appeared since."

"Great men for eighteen hundred years developed the theory that before Adam's disobedience there was no death, and therefore neither ferocity nor venom. ...St. Augustine expressly confirmed and emphasized the view that the vegetable as as well as the animal kingdom was cursed on account of man's sin. Two hundred years later this utterance had been echoed on from father to father of the Church until it was caught by Bede; he declared that before man's fall animals were harmless, but were made poisonous or hurtful by Adam's sin, and he said, "Thus fierce and poisonous animals were created for terrifying man (because God foresaw that he would sin), in order that he might be made aware of the final punishment of hell." In the twelfth century this view was incorporated by Peter Lombard into his great theological work, the Sentences which became a text-book of theology through the middle ages. He affirmed that "no created things would have been hurtful to man had he not sinned; they became hurtful for the sake of terrifying and punishing vice or of proving and perfecting virtue; they were created harmless, and on account of sin became hurtful." John Wesley... declared that before Adam's sin "none of these attempted to devour or in any wise hurt one another"; "the spider was as harmless as the fly, and did not lie in wait for blood." ...not until, in our own time, geology revealed the remains of vast multitudes of carnivorous creatures, many of them with half-digested remains of other animals in their stomachs, all extinct long ages before the appearance of man upon earth, was a victory won by science over theology in this field."

"Some difficulties arose here and there as zoology progressed and revealed ever-increasing numbers of species; but through the Middle Ages, and indeed long after the Reformation, these difficulties were easily surmounted by making the ark of Noah larger and larger, and especially by holding that there had been a human error in regard to its measurement."

"Naturally there was developed among both ecclesiastics and laymen a human desire to... know what the creation really is. ...Aristotle had made the first really great attempt to satisfy this curiosity and had begun a development of studies in natural history which remains one of the leading achievements in the story of our race. ...But the feeling which we have already seen so strong in the early Church—that all study of Nature was futile in view of the approaching end of the world—indicated so clearly in the New Testament and voiced so powerfully by Lactantius and St. Augustine—held back this current of thought for many centuries. ...There was indeed an influence coming from the Hebrew Scriptures themselves which wrought powerfully to this end. ...the grand utterances in the Psalms regarding the beauties and wonders of creation, in all the glow of the truest poetry, ennobled the study even among those whom logic drew away from it. But as a matter of course... too much prying into the secrets of Nature was very generally held to be dangerous both to body and soul; only for showing forth God's glory and his purposes in the creation were such studies praiseworthy. The great work of Aristotle was under eclipse. The early Christian thinkers gave little attention to it. ...In place of research came authority—the authority of the Scriptures as interpreted by the Physiologus and the Bestiaries (mingling scriptural statements, legends of the saints, and fanciful inventions with pious intent and childlike simplicity) and these remained the principal source of thought on animated Nature for over a thousand years. ...Pope Gelasius administered a rebuke to the Physiologus; but the interest in Nature was too strong: the great work on Creation by St. Basil had drawn from the Physiologus precious illustrations of Holy Writ, and the strongest of the early popes, Gregory the Great, virtually sanctioned it."

"Thus was developed a sacred science of creation and of the divine purpose in Nature, which went on developing from the fourth century to the nineteenth—from St Basil to St Isidore of Seville, from Isidore to Vincent of Beauvais, and from Vincent to Archdeacon Paley and the Bridgewater Treatises. Like all else in the Middle Ages, this sacred science was developed purely by theological methods. Neglecting the wonders which the dissection of the commonest animals would have afforded them, these naturalists attempted to throw light into Nature by ingenious use of scriptural texts, by research among the lives of the saints, and by the plentiful application of metaphysics. Hence even such strong men as St. Isidore of Seville treasured up accounts of the unicorn and dragons mentioned in the Scriptures and of the phoenix and basilisk in profane writings."

"In the middle of the thirteenth century we have a triumph of this theological method in the great work of the English Franciscan Bartholomew on The Properties of Things. The theological method as applied to science consists largely in accepting tradition and in spinning arguments to fit it. In this field Bartholomew was a master. Having begun with the intent mainly to explain the allusions in Scripture to natural objects, he soon rises logically into a survey of all Nature. Discussing the "cockatrice" of Scripture he tells us: ..."His ashes be accounted profitable in working of alchemy, and namely in turning and changing of metals." ...Naturally this good Franciscan naturalist devotes much thought to the dragons mentioned in Scripture. ...His book was translated into the principal languages of Europe, and was one of those most generally read during the Ages of Faith. It maintained its position nearly three hundred years; even after the invention of printing it held its own, and in the fifteenth century there were issued no less than ten editions of it in Latin, four in French, and various versions of it in Dutch, Spanish, and English. Preachers found it especially useful in illustrating the ways of God to man. It was only when the great voyages of discovery substituted ascertained fact for theological reasoning in this province that its authority was broken."

"The same sort of science flourished in the Bestiaries, which were used everywhere, and especially in the pulpits, for the edification of the faithful. ...Pious use was constantly made of this science, especially by monkish preachers. The phoenix rising from his ashes proves the doctrine of the resurrection; the structure and mischief of monkeys proves the existence of demons; the fact that certain monkeys have no tails proves that Satan has been shorn of his glory; the weasel, which "constantly changes its place, is a type of the man estranged from the word of God, who findeth no rest.""

"The moral treatises of the time often took the form of works on natural history, in order the more fully to exploit these religious teachings of Nature. Thus from the book On Bees of the Dominican Thomas of Cantimpre, we learn that "wasps persecute bees and make war on them out of natural hatred"; and these, he tells us, typify the demons who dwell in the air and with lightning and tempest assail and vex mankind—whereupon he fills a long chapter with anecdotes of such demonic warfare on mortals. In like manner his fellow-Dominican, the inquisitor Nider, in his book The Ant Hill, teaches us that the ants in Ethiopia, which are said to have horns and to grow so large as to look like dogs, are emblems of atrocious heretics, like Wyclif and the Hussites, who bark and bite against the truth; while the ants of India, which dig up gold out of the sand with their feet and hoard it, though they make no use of it, symbolize the fruitless toil with which the heretics dig out the gold of Holy Scripture and hoard it in their books to no purpose."

"This pious spirit not only pervaded science; it bloomed out in art, and especially in the cathedrals. In the gargoyles overhanging the walls, in the grotesques clambering about the towers or perched upon pinnacles, in the dragons prowling under archways or lurking in bosses of foliage, in the apocalyptic beasts carved upon the stalls of the choir, stained into the windows, wrought into the tapestries, illuminated in the letters and borders of psalters and missals, these marvels of creation suggested everywhere morals from the Physiologus, the Bestiaries, and the Exempla."

"After Bruno's death, during the first half of the seventeenth century, Descartes seemed about to take the leadership of human thought... in promoting an evolution doctrine as regards the mechanical formation of the solar system... but his constant dread of persecution, both from Catholics and Protestants, led him steadily to veil his thoughts and even to suppress them. The execution of Bruno had occurred in his childhood, and in the midst of his career he had watched the Galileo struggle in all its stages. He had seen his own works condemned by university after university under the direction of theologians and placed upon the Roman Index. ...Since Roger Bacon, perhaps, no great thinker had been so completely abased and thwarted by theological oppression."
