A History of the Warfare of Science with Theology in Christendom

“My hope is to aid—even if it be but a little—in the gradual and healthful dissolving away of this mass of unreason, that the stream of "religion pure and undefiled" may flow on broad and clear, a blessing to humanity.”

“As I look back across the intervening years, I know not whether to be more astonished or amused at our simplicity. Opposition began at once.”

“Having been invited to deliver a lecture the great hall of the Cooper Institute at New York, I took as my subject The Battlefields of Science, maintaining the thesis which follows:”

“In all modern history, interference with science in the supposed interest of religion, no matter how conscientious such interference may have been, has resulted in the direst evils both to religion and to science, and invariably; and, on the other hand, all untrammelled scientific investigation, no matter how dangerous to religion some of its stages may have seemed for the time to be, has invariably resulted in the highest good both of religion and of science.”

“Meanwhile Prof. John W. Draper published his book on The Conflict between Science and Religion, a work of great ability, which, as I then thought, ended the matter, so far as my giving it further attention was concerned.”

“My belief is that in the field left to them—their proper field—the clergy will more and more, as they cease to struggle against scientific methods and conclusions, do work even nobler and more beautiful than anything they have heretofore done. And this is saying much.”

“Thus may the declaration of Micah as to the requirements of Jehovah, the definition by St. James of "pure religion and undefiled," and, above all, the precepts and ideals of the blessed Founder of Christianity himself, be brought to bear more and more effectively on mankind.”

“The sun of spring has done its work on the Neva; the great river flows tranquilly on, a blessing and a joy; the mujiks are forgotten.”

“As late as the middle of the eighteenth century, when Buffon attempted to state simple geological truths, the theological faculty of the Sorbonne forced him to make and to publish a most ignominious recantation which ended with these words: "I abandon everything in my book respecting the formation of the earth, and generally all which may be contrary to the narrative of Moses."”

“Yet, alas! within two centuries after Lightfoot's great biblical demonstration as to the exact hour of creation, it was discovered that at that hour an exceedingly cultivated people, enjoying all the fruits of a highly developed civilization, had long been swarming in the great cities of Egypt, and that other nations hardly less advanced had at that time reached a high development in Asia.”

“The Creator was sometimes represented with a single body, but with three faces, thus showing that Christian belief had... gone through substantially the same cycle which an earlier form of belief had made ages before in India, when the Supreme Being was represented with one body but with the three faces of Brahma, Vishnu, and Siva.”

“Down to a period almost within living memory, it was held, virtually "always, everywhere, and by all," that the universe, as we now see it, was created literally and directly by the voice or hands of the Almighty, or by both—out of nothing—in an instant or in six days, or in both—about four thousand years before the Christian era—and for the convenience of the dwellers upon the earth, which was at the base and foundation of the whole structure.”

“Each of the great sacred books of the world is precious, and all, in the highest sense, are true. Not one of them, indeed, conforms to the measure of what mankind has now reached in historical and scientific truth; to make a claim to such conformity is folly, for it simply exposes those who make it and the books for which it is made to loss of their just influence.”

“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.”

“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.”

“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.”

“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.”

“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.”

“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.”

“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.”

“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.”

“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...”

“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.”

“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.”

“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.”

“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.”

“Leibnitz, though not propounding any full doctrine on evolution, gave it an impulse by suggesting a view contrary to the sacrosanct belief in the immutability of species... His punishment at the hands of the Church came a few years later, when in 1712, the Jesuits defeated his attempt to found an Academy of Science at Vienna.”

“Spinoza, Hume, and Kant... might have done much to aid in the development of a truer theory had not the theologic atmosphere of their times been so unpropitious.”

“Early in the eighteenth century Benoist de Maillet, a man of the world, but a wide observer and close thinker upon Nature... was led into the idea of the transformation of species and so into a theory of evolution, which in some important respects anticipated modern ideas. ...But he fell between two ranks of adversaries ...the Church authorities denounced him as a freethinker... Voltaire ridiculed him as a devotee.”

“De Maillet had seen in the presence of fossils on high mountains a proof that these mountains were once below the sea, Voltaire, recognizing in this an argument for the deluge of Noah, ridiculed the new thinker without mercy.”

“De Maillet received no recognition until, very recently, the greatest men of science in England and France have united in giving him his due. But his work was not lost, even in his own day; Robinet and Bonnet pushed forward victoriously on helpful lines.”

“Church authorities was so shocked by Linnaeus's proofs of a sexual system in plants that for many years his writings were prohibited in the Papal States and in various other parts of Europe... Not until 1773 did one of the more broad minded cardinals—Zelanda—succeed in gaining permission that Prof. Minasi should discuss the Linnaean system at Rome.”

“To all appearance he [Linnaeus] continued to adhere to the doctrine that all existing species had been created by the Almighty "in the beginning," and that since "the beginning" no new species had appeared.”

“For his [Buffon's] simple statement of truths in natural science which are today truisms, he was... dragged forth by the theological faculty, forced to recant publicly, and to print his recantation. In this he announced, "I abandon everything in my book respecting the formation of the earth, and generally all which may be contrary to the narrative of Moses."”

“From Treviranus came, in 1802, his work on biology, and in this he gave forth the idea that from forms of life originally simple had arisen all higher organizations by gradual development; that every living creature has a capacity for receiving modifications of its structure from external influences; and that no species had become really extinct, but that each had passed into some other species.”

“Lamarck's declaration, especially, that the development of organs is in ratio to their employment, and his indications of the reproduction in progeny of what is gained or lost in parents by the influence of circumstances, entered as a most effective force into the development of the evolution theory.”

“Geoffroy Saint-Hilaire... As early as 1795... had begun to form a theory that species are various modifications of the same type, and this theory he developed, testing it at various stages... It fell to his lot to bear the brunt in a struggle against heavy odds which lasted many years.”

“Geoffroy Saint-Hilaire stoutly withstood him [Cuvier], braving non-recognition, ill-treatment, and ridicule. Treviranus, afar off in his mathematical lecture-room at Bremen, seemed simply forgotten.”

“On July 1, 1858, there were read before the Linnæan Society at London two papers—one presented by Charles Darwin, the other by Alfred Russel Wallace—and with the reading of these papers the doctrine of evolution by natural selection was born. Then and there a fatal breach was made in the great theological barrier of the continued fixity of species since the creation.”

“To one man only did he [Darwin] reveal his thought—to Dr. Joseph Hooker, to whom in 1844, under the seal of secrecy, he gave a summary of his conclusions.”

“In support of the new doctrine came a world of new proofs those which Darwin himself added... led the way and these were followed by the discoveries of Wallace, Bates, Huxley, Marsh, Cope, Leidy, Haeckel, Müller, Gaudry, and a multitude of others in all lands.”

“Darwin's Origin of Species had come into the theological world like a plough into an ant-hill. Everywhere those thus rudely awakened from their old comfort and repose had swarmed forth angry and confused. Reviews, sermons, books light and heavy, came flying at the new thinker from all sides.”

“In the Quarterly Review... Wilberforce Bishop of Oxford... declared that Darwin was guilty of "a tendency to limit God's glory in creation"; that "the principle of natural selection is absolutely incompatible with the word of God"...”

“In an address before the "Academia," which had been organized to combat "science falsely so called," Cardinal Manning declared his abhorrence of the new view of Nature, and described it as "a brutal philosophy—to wit, there is no God, and the ape is our Adam." ...These attacks from such eminent sources set the clerical fashion for several years.”

“Dr. Perry, Lord Bishop of Melbourne, in a most bitter book on Science and the Bible, declared that the obvious object of Chambers, Darwin, and Huxley is "to produce in their readers a disbelief of the Bible."”

“All opposition had availed nothing; Darwin's work and fame were secure. As men looked back over his beautiful life—simple, honest, tolerant, kindly—and thought upon his great labours in the search for truth, all the attacks faded into nothingness.”

“The theory of an evolution process in the formation of the universe and of animated nature is established, and the old theory of direct creation is gone forever. In place of it science has given us conceptions far more noble, and opened the way to an argument for design infinitely more beautiful than any ever developed by theology.”

“According to Cosmas [Indicopleustes], the earth is a parallelogram, flat, and surrounded by four seas. It is four hundred days' journey long and two hundred broad. At the outer edges of these four seas arise massive walls closing in the whole structure and supporting the firmament or vault of the heavens, whose edges are cemented to the walls. These walls inclose the earth and all the heavenly bodies.”

“Starting with the expression applied in the ninth chapter of Hebrews to the tabernacle in the desert, Cosmas insists, with other interpreters of his time, that it gives the key to the whole construction of the world. The universe is therefore made on the plan of the jewish tabernacle—box-like and oblong. ..He works all this into his system, and reveals, as he thinks, treasures of science.”

“Cosmas suggests that at the north of the earth is a great mountain, and that at night the sun is carried behind this; but some of the commentators ventured to express a doubt here: they thought that the sun was pushed into a pit at night and pulled out in the morning. ...The treatise closes with rapturous assertions that not only Moses and the prophets, but also angels and apostles, agree to the truth of his doctrine, and that at the last day God will condemn all who do not accept it”

“St. Basil and St. Ambrose were tolerant enough to allow that a man might be saved who thought the earth inhabited on its opposite sides; but the great majority of the fathers doubted the possibility of salvation to such misbelievers.”

“The sixth century Procopius of Gaza... declares that, if there be men on the other side of the earth, Christ must have gone there and suffered a second time to save them; and, therefore, that there must have been there, as necessary preliminaries to his coming, a duplicate Eden, Adam, serpent, and deluge.”

“At the end of the sixth century... St. Isidore of Seville... pondered over ancient thought in science and... dared proclaim his belief in the sphericity of the earth; but with that he stopped. As to the antipodes... he shuns the whole question as unlawful, subjects reason to faith, and declares that men can not and ought not to exist on opposite sides of the earth.”

“Boniface immediately declared against the revival of such a heresy the doctrine of the antipodes; he stigmatized it as an that there are men beyond the reach of the means of salvation; he attacked Virgil, and called on Zachary for aid. The Pope... cited passages from the book of Job and the Wisdom of Solomon against the doctrine of the antipodes; he declared it "perverse, iniquitous, and against Virgil's own soul"...”

“The great encyclopedist of the Middle Ages, Vincent of Beauvais, though he accepts the sphericity of the earth, treats the doctrine of the antipodes as disproved, because contrary to Scripture.”

“As a rule, when there arises a thinker as great in theology as Kepler in science, the whole mass of his conclusions ripens into a dogma. His disciples labor not to test it, but to establish it; and while in the Catholic Church, it becomes a dogma to be believed or disbelieved under the penalty of damnation, it becomes in the Protestant Church the basis for one more sect.”
