TOHENRY WILLIAMS SAGE,OF BROOKLYN, N. Y.,A CHRISTIAN MAN, WHO HAS PROVED THAT HE WELCOMESALL TRUTH, AND FEARS NONE,THIS LITTLE BOOK IS INSCRIBED,WITH FEELINGS OFTHOROUGH RESPECT AND ESTEEM.
Inits earlier abridged form this address was given as a Phi Beta Kappa oration at Brown University, and, as a lecture, at New York, Boston, New Haven, Ann Arbor, and elsewhere. In that form, substantially, it was published inThe Popular Science Monthly. I have now given it careful revision, correcting some errors, and extending it largely by presenting new facts and developing various points of interest in the general discussion. Among the subjects added or rewrought are: in Astronomy, the struggle of Galileo and the retreat of the Church after its victory; in Chemistry and Physics, the compromise between Science and Theology made by Thomas Aquinas, and the unfortunate route taken by Science in consequence; in Anatomy and Medicine, the earlier growth ofecclesiastical distrust of these sciences; in Scientific Education, the dealings of various European universities with scientific studies; in Political and Social Science, a more complete statement of the opposition of the Church, on Scriptural grounds, to the taking of interest for money; and, in the conclusion, a more careful summing up. If I have seemed to encumber the text with notes, it has been in the intention to leave no important assertion unsupported; and in the hope that others—less engrossed with administrative care than myself—may find in them indications for more extended studies in various parts of the struggle which I have but sketched.
A. D. W.
Cornell University,March, 1876.
I purposeto present an outline of the great, sacred struggle for the liberty of science—a struggle which has lasted for so many centuries, and which yet continues. A hard contest it has been; a war waged longer, with battles fiercer, with sieges more persistent, with strategy more shrewd than in any of the comparatively transient warfare of Cæsar or Napoleon or Moltke.
I shall ask you to go with me through some of the most protracted sieges, and over some of the hardest-fought battle-fields of this war. We will look well at the combatants; we will listen to the battle-cries; we will note the strategy of leaders, the cut and thrust of champions, the weight of missiles, the temper of weapons; we will look also at the truces and treaties, and note the delusive impotency of all compromises in which the warriors for scientific truth have consented to receive directionor bias from the best of men uninspired by the scientific spirit, or unfamiliar with scientific methods.
My thesis, which, by an historical study of this warfare, I expect to develop, is the following: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 untrammeled 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 of religion and of science.I say "invariably." I mean exactly that. It is a rule to which history shows not one exception.
It would seem, logically, that this statement cannot be gainsaid. God's truths must agree, whether discovered by looking within upon the soul, or without upon the world. A truth written upon the human heart to-day, in its full play of emotions or passions, cannot be at any real variance even with a truth written upon a fossil whose poor life ebbed forth millions of years ago.
This being so, it would also seem a truth irrefragable, that the search for each of these kinds of truth must be followed out on its own lines, by its own methods, to its own results, without any interference from investigators on other lines, orby other methods. And it would also seem logical to work on in absolute confidence that whatever, at any moment, may seem to be the relative positions of the two different bands of workers, they must at last come together, for Truth is one.
But logic is not history. History is full of interferences which have cost the earth dear. Strangest of all, some of the direst of them have been made by the best of men, actuated by the purest motives, and seeking the noblest results. These interferences, and the struggle against them, make up the warfare of science.
One statement more, to clear the ground. You will not understand me at all to say that religion has done nothing for science. It has done much for it. The work of Christianity has been mighty indeed. Through these two thousand years, despite the waste of its energies on all the things its Blessed Founder most earnestly condemned—on fetich and subtlety and war and pomp—it has undermined servitude, mitigated tyranny, given hope to the hopeless, comfort to the afflicted, light to the blind, bread to the starving, joy to the dying, and this work continues. And its work for science, too, has been great. It has fostered science often. Nay, it has nourished that feeling of self-sacrifice for human good, which has nerved some of the bravest men for these battles.
Unfortunately, a devoted army of good menstarted centuries ago with the idea that independent scientific investigation is unsafe—that theology must intervene to superintend its methods, and the Biblical record, as an historical compendium and scientific treatise, be taken as a standard to determine its results. So began this great modern war.
The first typical battle-field to which I would refer is that of Geography—the simplest elementary doctrine of the earth's shape and surface.
Among the legacies of thought left by the ancient world to the modern, were certain ideas of the rotundity of the earth. These ideas were vague; they were mixed with absurdities; but they weregerm ideas, and, after the barbarian storm which ushered in the modern world had begun to clear away, these germ ideas began to bud and bloom in the minds of a few thinking men, and these men hazarded the suggestion that the earth is round—is a globe.[1]
The greatest and most earnest men of the time took fright at once. To them, the idea of the earth's rotundity seemed fraught with dangers to Scripture: by which, of course, they meanttheir interpretationof Scripture.
Among the first who took up arms against the new thinkers was Eusebius. He endeavored to turn off these ideas by bringing science into contempt, and by making the innovators understand that he and the fathers of the Church despised all such inquiries. Speaking of the innovations in physical science, he said: "It is not through ignorance of the things admired by them, but through contempt of their useless labor, that we think little of these matters, turning our souls to better things."[2]
Lactantius asserted the ideas of those studying astronomy to be "mad and senseless."[3]
But the attempt to "flank" the little phalanx of thinkers did not succeed, of course. Even such men as Lactantius and Eusebius cannot pooh-pooh down a new scientific idea. The little band of thinkers went on, and the doctrine of the rotundity of the earth naturally led to the consideration of the tenants of the earth's surface, and another germ idea was warmed into life—the idea of the existence of the antipodes, the idea of the existence of countries and men on the hemisphere opposite to ours.[4]
At this the war-spirit waxed hot. Those great and good men determined to fight. To all of them such doctrines seemed dangerous; to most of them they seemed damnable. St. Basil and St. Ambrose[5]were tolerant enough to allow that a man might be saved who believed the earth to be round, and inhabited on its opposite sides; but the great majority of the Fathers of the Churchutterly denied the possibility of salvation to such misbelievers.
Lactantius asks: "... Is there any one so senseless as to believe that there are men whose footsteps are higher than their heads?—that the crops and trees grow downward?—that the rains and snow and hail fall upward toward the earth?... But if you inquire from those who defend these marvelous fictions, why all things do not fall into that lower part of the heaven, they reply that such is the nature of things, that heavy bodies are borne toward the middle, like the spokes of a wheel; while light bodies, such as clouds, smoke, and fire, tend from the centre toward the heavens on all sides. Now, I am at loss what to say of those who, when they have once erred, steadily persevere in their folly, and defend one vain thing by another."
St. Augustine seems inclined to yield a little in regard to the rotundity of the earth, but he fights the idea that men exist on the other side of the earth, saying that "Scripture speaks of no such descendants of Adam."
But this did not avail to check the idea. What may be called the flank movement, as represented by Eusebius, had failed. The direct battle given by Lactantius, Augustine, and others, had failed; in the sixth century, therefore, the opponents of the new ideas built a great fortress and retiredinto that. It was well built and well braced. It was nothing less than a complete theory of the world, based upon the literal interpretation of texts of Scripture, and its author was Cosmas Indicopleustes.[6]
According to Cosmas, the earth is a parallelogram, flat, and surrounded by four great seas. At the outer edges of these seas rise immense walls closing in the whole structure. These walls support the vault of the heavens, whose edges are cemented to the walls; walls and vault shut in the earth and all the heavenly bodies. The whole of this theologic, scientific fortress was built most carefully, and, as was then thought, most scripturally.
Starting with the expression,Το ἁγιον κοσμικὁν, applied in the ninth chapter of Hebrews to the tabernacle in the desert, he insists, with other interpreters of his time, that it gives a key to the whole construction of the world. The universe is,therefore, made on the plan of the Jewish Tabernacle—box-like and oblong.
Coming to details, he quotes those grand words of Isaiah, "It is he that sitteth upon the circle of the earth, ... that stretcheth out the heavens like a curtain, and spreadeth them out like a tent to dwell in,"[7]and the passage in Job, which speaks of the "pillars of heaven."[8]He turns all that splendid and precious poetry into a prosaic statement, and gathers therefrom, as he thinks, treasures for science.
This vast box is then divided into two compartments, one above the other. In the first of these, men live and stars move; and it extends up to the first solid vault or firmament, where live the angels, a main part of whose business it is to push and pull the sun and planets to and fro. Next he takes the text, "Let there be a firmament in the midst of the waters, and let it divide the waters from the waters,"[9]and other texts from Genesis. To these he adds the text from the Psalms, "Praise him, ye heaven of heavens, and ye waters that be above the heavens,"[10]casts that outburst of poetry into his crucible with the other texts, and, after subjecting them to sundry peculiar processes, brings out the theory that over this first vault is a vast cistern containing the waters. He then takes theexpression in Genesis regarding the "windows of heaven,"[11]and establishes a doctrine regarding the regulation of the rain, which is afterward supplemented by the doctrine that the angels not only push and pull the heavenly bodies, to light the earth, but also open and close the windows of heaven to water it.
To find the character of the surface of the earth, Cosmas studies the table of shew-bread in the Tabernacle. The dimensions of that table prove to him that the earth is flat and twice as long as broad; the four corners of the table symbolize the four seasons. To account for the movement of the sun, 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 great pit at night, and was pulled out in the morning. Nothing can be more touching in its simplicity than Cosmas's closing of his great argument. He bursts forth in raptures, declaring that Moses, the prophets, evangelists, and apostles, agree to the truth of his doctrine.[12]
Such was the fortress built against human science in the sixth century, by Cosmas; and it stood. The innovators attacked it in vain. The greatest minds in the Church devoted themselves to buttressing it with new texts, and throwing out new outworks of theologic reasoning. It stood firm for two hundred years, when a bishop—Virgilius of Salzburg—asserts his belief in the existence of the antipodes.
It happened that there then stood in Germany, in the first years of the eighth century, one of the greatest and noblest of men—St. Boniface. His learning was of the best then known; in labors he was a worthy successor to the apostles; his genius for Christian work made him, unwillingly, Primate of Germany; his devotion afterward led him, willingly, to martyrdom. There sat, too, at that time, on the papal throne, a great Christian statesman—Pope Zachary. Boniface immediately declares against the revival of such a terrible heresy as the existence of the antipodes. He declares that it amounts to the declaration that there are men onthe earth beyond the reach of the means of salvation; he attacks Virgilius; he calls on Zachary for aid; effective measures are taken, and we hear no more of Virgilius or his doctrine.
Six hundred years pass away, and in the fourteenth century two men publicly assert the doctrine. The first of these, Peter of Abano, escapes punishment by natural death; the second, known as Cecco d'Ascoli, a man of seventy years, is burned alive. Nor was that all the punishment: that great painter, Orcagna, whose terrible works you may see on the walls of the Campo Santa at Pisa, immortalized Cecco by representing him in the flames of hell.[13]
Still the idea lived and moved, and a hundred years later we find the theologian Tostatus protestingagainst the doctrine of the antipodes as "unsafe." He has invented a new missile—the following syllogism: "The apostles were commanded to go into all the world, and to preach the gospel to every creature; they did not go to any such part of the world as the antipodes, they did not preach to any creatures there:ergo, no antipodes exist." This is just before the time of Columbus.
Columbus is the next warrior. The world has heard of his battles: how the Bishop of Ceuta worsted him in Portugal; how at the Junta of Salamanca the theologians overwhelmed him with quotations from the Psalms, from St. Paul, and from St. Augustine.[14]And even after Columbus was triumphant, and after his voyage had greatly strengthened the theory of the earth's sphericity, the Church, by its highest authority, was again solemnly committed to the theory of the earth's flatness. In 1493 Pope Alexander VI. issues a bull laying down a line of demarkation upon the earth as a flat disk; this line was drawn from north to south, west of the Azores and Canary Islands; and the Pope, in the plenitude of his knowledge and powers, declared that all landsdiscovered east of this line should belong to the Portuguese, and all discovered west of it should belong to the Spaniards. This was hailed as an exercise of divinely illuminated power in the Church; but in a few years difficulties arose. The Portuguese claimed Brazil, and, of course, had no difficulty in showing that it could be reached by sailing to the east of the line, provided the sailing were sufficiently long-continued. The bull of Pope Alexander quietly passed into the catalogue of ludicrous errors.[15]
But in 1519 Science gains a crushing victory. Magalhaens makes his famous voyages. He proves the earth to be round, for his great expedition circumnavigates it; he proves the doctrine of the antipodes, for he sees the men of the antipodes;[16]but even this does not end the war. Many earnest and good men oppose the doctrine for two hundred years longer. Then the French astronomers make their measurements of degrees in equatorial and polar regions, and add to other proofs that of the lengthened pendulum: whenthis was done, when the deductions of science were seen to be established by the simple test of measurement, beautifully, perfectly, then and then only this war of twelve centuries ended.[17]
And now, what was the result of this war? The efforts of Eusebius and Lactantius to deaden scientific thought; the efforts of Augustine to combat it; the efforts of Cosmas to stop it by dogmatism; the efforts of Boniface, and Zachary, and others to stop it by force, conscientious as they all were, had resulted in what? Simply in forcing into many noble minds this most unfortunate conviction, that Science and Religion are enemies; simply in driving away from religion hosts of the best men in all those centuries. The result was wholly bad. No optimism can change that verdict.
On the other hand, what was gained by the warriors of science for religion? Simply, a far more ennobling conception of the world, and a far truer conception of Him who made and who sustains it.
Which is the more consistent with a great, true religion—the cosmography of Cosmas, or that of Isaac Newton? Which presents the nobler foodfor religious thought—the diatribes of Lactantius, or the astronomical discourses of Thomas Chalmers?
The next great battle was fought on a question relating to theposition of the earth among the heavenly bodies. On one side, the great body of conscientious religious men planted themselves firmly on the geocentric doctrine—the doctrine that the earth is the centre, and that the sun and planets revolve about it. The doctrine was old, and of the highest respectability.[18]The very name, Ptolemaic theory, carried weight. It had been elaborated until it accounted well for the phenomena. Exact textual interpreters of Scripture cherished it, for it agreed with the letter of the sacred text.[19]
But, most important of all, it was stamped with the seal of St. Thomas Aquinas. The sainted theologian—the glory of the Mediæval Church, the "angelic doctor"—he to whom it was believed animage of the Crucified had spoken words praising his writings—had shown in his treatise on the Heaven and Earth, by philosophy, theology, and revelation, that the position of the earth must be in the centre.[20]
Still the germs of the heliocentric theory[21]had been planted long before, and well planted; it had seemed ready even to bloom forth in the fifth century, from the mind of Martianus Capella, and in the fifteenth from the mind of Cardinal de Cusa; but it could not be forgotten that St. Thomas had elaborated the opposite view; the chill of dogmatism was still over the earth, and up to the beginning of the sixteenth century there had come to this great truth neither bloom nor fruitage.[22]
Quietly, however, the soil was receiving enrichment, and the air warmth. The processes of mathematics were constantly improved, the heavenly bodies were steadily though silently observed; and at length appeared, afar off from the centres of thought, on the borders of Poland, a plain, simple-minded scholar, who first fairly uttered to the world the truth, now so commonplace, then so astounding, that the sun and planets do not revolve about the earth, but that the earth and planets revolve about the sun, and that man was Nicholas Kopernik.[23]
Kopernik had been a professor at Rome, but,as this truth grew within him, he seemed to feel that at Rome he was no longer safe.[24]
To publish this thought was dangerous indeed, and for more than thirty years it lay slumbering in the minds of Kopernik and the friends to whom he had privately intrusted it.
At last he prepares his great work on theRevolution of the Heavenly Bodies, and dedicates it to the pope himself. He next seeks a place of publication. He dares not send it to Rome, for there are the rulers of the older Church ready to seize it. He dares not send it to Wittenberg, for there are the leaders of Protestantism no less hostile. It is therefore intrusted to Osiander, of Nuremberg.[25]
But, at the last moment, Osiander's courage fails him. He dares not launch the new thought boldly. He writes a groveling preface; endeavors to excuse Kopernik for his novel idea. He inserts the apologetic lie that Kopernik propounds the doctrine of the movement of the earth, not as afact, but as anhypothesis; he declares that it is lawful for an astronomer to indulge hisimagination, and that this is what Kopernik has done.
Thus was the greatest and most ennobling, perhaps, of scientific truths—a truth not less ennoblingto religion than to science—forced, in coming into the world, to sneak and crawl.[26]
On the 24th of May, 1543, the newly-printed book first arrived at the house of Kopernik. It was put into his hands; but he was on his death-bed. A few hours later he was beyond the reach of those mistaken, conscientious men, whose consciences would have blotted his reputation, and perhaps have destroyed his life.
Yet not wholly beyond their reach. Even death could not be trusted to shield him. There seems to have been fear of vengeance upon his corpse, for on his tombstone was placed no record of his life-long labors, no mention of his greatdiscovery. There were graven upon it affecting words, which may be thus simply translated: "I ask not the grace accorded to Paul, not that given to Peter; give me only the favor which thou didst show to the thief on the cross." Not till thirty years after did a friend dare write on his tombstone a memorial of his discovery.[27]
The book was taken in hand by the proper authorities. In due time it was solemnly condemned; to read it was to risk damnation; and the world accepted the decree.[28]The earnest theologiansof the period immediately wheeled their batteries of sacred learning to support the Church in its effort to beat back the terrible doctrine that the earth revolves about the sun. Among the most vigorous of them in Northern Europe was Fromundus. From the shadow of the Cathedral of Antwerp he sent forth his famous treatise, theAnti-Aristarchus, full of the strongest arguments against the new theory. His very title-page was a contemptuous insult to the memory of Kopernik, since it paraded the assumption that the new truth was only an old and exploded theory of Aristarchus. He declares that "sacred Scripture fights against the Copernicans." To prove that the sun revolves about the earth, he cites the passage in the Psalms which speaks of the sun "which cometh forth as a bridegroom out of his chamber." To prove that the earth stands still, he quotes the passage from Ecclesiastes, "the earth standeth fast forever." To show the utter futility of the Copernican ideas, he indulges in scientific reasoning as he understands it—declaring that, if the hated theory were true, "the wind would constantly blow from the east; we should with great difficulty hear sounds against such a wind;" that "buildings, and the earth itself,would fly off with such a rapid motion;" and, greatest weapon of all, he works up, by the use of Aristotle and Thomas Aquinas, a demonstration from theology and science combined, that the earth must stand in the centre, and that the sun must revolve about it.[29]
Doubtless many will at once exclaim against the Roman Catholic Church for this. Justice compels me to say that the founders of Protestantism were no less zealous against the new scientific doctrine. Said Martin Luther: "People gave ear to an upstart astrologer, who strove to show that the earth revolves, not the heavens or the firmament, the sun and the moon. Whoever wishes to appear clever must devise some new system, which of all systems is, of course, the very best. This fool wishes to reverse the entire science of astronomy. But Sacred Scripture tells us that Joshua commanded the sun to stand still, and not the earth."
Melanchthon, mild as he was, was not behind Luther in condemning Kopernik. In his treatise,Initia Doctrinæ Physicæ, he says: "The eyes arewitnesses that the heavens revolve in the space of twenty-four hours. But certain men, either from the love of novelty, or to make a display of ingenuity, have concluded that the earth moves; and they maintain that neither the eighth sphere nor the sun revolves.... Now, it is a want of honesty and decency to assert such notions publicly, and the example is pernicious. It is the part of a good mind to accept the truth as revealed by God, and to acquiesce in it." Melanchthon then cites passages from the Psalms and from Ecclesiastes which he declares assert positively and clearly that the earth stands fast, and that the sun moves around it, and adds eight other proofs of his proposition that "the earth can be nowhere, if not in the centre of the universe."[30]
And Protestant people were not a whit behind Catholic in following out these teachings. The people of Elbing made themselves merry over a farce in which Kopernik was the main object of ridicule. The people of Nuremberg, a great Protestantcentre, caused a medal to be struck, with inscriptions ridiculing the philosopher and his theory.[31]
Then was tried, also, one piece of strategy very common formerly in battles between theologians themselves. It consists in loud shoutings that the doctrine attacked is outworn, and already refuted—that various distinguished gentlemen have proved it false—that it is not a living truth, but a detected lie—that, if the world listens to it, that is simply because the world is ignorant. This strategy was brought to bear on Kopernik. It was shown that his doctrine was simply a revival of the Pythagorean notion, which had been thoroughly exploded. Fromundus, as we have seen in his title-page and throughout his book, delights in referring to the doctrine of the revolution of the planets around the sun, as "that Pythagorean notion." This mode of warfare was imitated by the lesser opponents, and produced, for some time, considerable effect.[32]
But the new truth could neither be laughed down nor forced down. Many minds had received it; only one tongue dared utter it. This new warrior was that strange mortal, Giordano Bruno.He was hunted from land to land, until, at last, he turns on his pursuers with fearful invectives. For this he is imprisoned six years, then burned alive and his ashes scattered to the winds. Still the new truth lived on; it could not be killed. Within ten years after the martyrdom of Bruno,[33]after a world of troubles and persecutions, the truth of the doctrine of Kopernik was established by the telescope of Galileo.[34]
Herein was fulfilled one of the most touching of prophecies. Years before, the enemies of Kopernik had said to him, "If your doctrines were true, Venus would show phases like the moon." Kopernik answered: "You are right; I know not what to say; but God is good, and will in time find an answer to this objection."[35]The God-givenanswer came when the rude telescope of Galileo showed the phases of Venus.
On this new champion, Galileo, the war was long and bitter. The supporters of what was called "sound learning" declared his discoveries deceptions, and his announcements blasphemy. Semi-scientific professors, endeavoring to curry favor with the Church, attacked him with sham science; earnest preachers attacked him with perverted Scripture![36]
I shall present this warfare at some length, because, so far as I can find, no careful outline of it has been given in our language, since the whole history was placed in a new light by the revelation of the trial documents in the Vatican Library, published for the first time by M. de l'Epinois in 1867.
The first important attack on Galileo began when he announced that his telescope had revealedthe moons of the planet Jupiter; the enemy saw that this strengthened the Copernican theory, and gave battle immediately.
The whole theory was denounced as impossible and impious. Professors, bred in the mixed science favored by the Church,[37]argued that the Bible clearly showed, by all applicable types, that there could be only seven planets; that this was proved by the seven golden candlesticks of the Apocalypse, by the seven-branched candlestick of the Tabernacle, and by the seven churches of Asia:[38]theologians showed the destructive consequences which must logically result to fundamental Christian truths: bishops and priests uttered impressive warnings to their flocks; and multitudes of the faithful besought the Inquisition to protect the fold by dealing speedily and sharply with the heretic.
In vain did Galileo try to save the great truths he had discovered, by his letters to the Benedictine Castelli and the Grand-duchess Christine, in which he argued that literal Biblical interpretation should not be applied to science; it was declared that by making such an argument his heresy was onlyrendered more detestable; that he was "worse than Luther or Calvin."
In vain did he try to prove the existence of satellites by showing them to the doubters through his telescope. They either declared it impious to look, or, if they did see them, denounced them as illusions from the devil. Good Father Clavius declared that to "see satellites of Jupiter, men had to make an instrument which would create them."[39]
The war on the Copernican theory, which up to that time had been carried on quietly, now flamed forth. It was declared that the doctrine was proved false by the standing still of the sun for Joshua; by the declarations that "the foundations of the earth are fixed so firm that they cannot be moved," and that the sun "runneth about from one end of heaven to the other."[40]
The Dominican father, Caccini, preached a sermon from the text, "Ye men of Galilee, why stand ye gazing up into heaven?" and this wretched pun was the first of a series of sharper weapons; for before Caccini finishes, he insists that "geometry is of the devil," and that "mathematiciansshould be banished as the authors of all heresies;" and, for this, the Church authorities gave Caccini promotion.[41]
Father Lorini proved that the doctrine was not only "heretical," but "atheistic," and besought the Inquisition to intervene. The Bishop of Fiesole screamed in rage against the Copernican system, and proposed to denounce Galileo to the grand-duke. The Archbishop of Pisa secretly sought to entrap Galileo and deliver him to the Inquisition at Rome. The Archbishop of Florence solemnly condemned the doctrines of Kopernik and Galileo as unscriptural.
But by far the most terrible champion who appeared against him was Bellarmin, one of the greatest of theologians, and one of the poorest of scientists. He was earnest, sincere, learned, but made the fearful mistake for the world of applying to science, direct, literal interpretation of Scripture.[42]
The weapons which men of Bellarmin's stamp used were theological. They held up before the world the dreadful consequences which must resultto Christian theology were the doctrine to prevail that the heavenly bodies revolve about the sun, and not about the earth. Their most tremendous theologic engine against Galileo was the idea that his pretended discovery "vitiated the whole Christian plan of salvation." Father Lecazre declared that it "cast suspicion on the doctrine of the Incarnation." Others declared that it "upset the whole basis of theology; that, if the earth is a planet, and one among several planets, it cannot be that any such great things have been done especially for it, as the Christian doctrine teaches. If there are other planets, since God makes nothing in vain, they must be inhabited; but how can these inhabitants be descended from Adam? How can they trace back their origin to Noah's ark? How can they have been redeemed by the Saviour?"[43]
Nor was this argument confined to the theologians of the Roman Church; Melanchthon, Protestant as he was, had already used it in his attacks upon the ideas of Kopernik and his school.[44]
In addition to this prodigious engine of war, there was kept up a terrific fire of smaller artillery in the shape of texts and scriptural extracts.
But the little telescope of Galileo still sweptthe heavens, and the next revelation announced was the system of mountains and valleys in the moon. This was a signal for another attack. It was declared that this, coupled with the statement that the moon shines by light reflected from the sun, was a contradiction of the statement in Genesis that the moon is a "great light" like the sun. To make the matter worse, a painter, placing the moon in a religious picture in its usual position beneath the feet of the Blessed Virgin, outlined on its surface mountains and valleys; this was denounced as a sacrilege logically resulting from the astronomer's heresy.
The next struggle was aroused when the hated telescope revealed spots upon the sun, and their motion, which indicated the sun's rotation. Monsignor Elci, head of the University of Pisa, forbade the Professor of Astronomy, Castelli, to mention these spots. Father Busaeus, at the University of Innspruck, forbade the astronomer Scheiner to allow the new discovery to be known there. At the College of Douay and the University of Louvain it was expressly placed under the ban, and this became the general rule among the Catholic universities and colleges of Europe. The Spanish universities were specially intolerant of this and similar ideas,[45]and up to a recent period they werestrictly forbidden in the most important university of all—that of Salamanca. In 1820 the Abbé Settele, professor at the College of Rome, having announced a work on Optics and Astronomy, the master of the sacred palace, under the authority of the old decrees against the teachings of Kopernik and Galileo, forbade the publication, and it was not until 1822 that Pope Pius VII. sanctioned a decision of the Inquisition permitting such teachings.[46]
Such are the consequences of placing the instruction of men's minds in the hands of those mainly absorbed in the work of saving men's souls.[47]Nothing could be more in accordance with the idea recently put forth by the Bishop of Montpellier, that the Church is alone fully empowered to promulgate scientific truth or direct university instruction; but science gained the victory here also. News came of observations of the solar spots, not only from Galileo in Italy, but from Fabricius in Holland. Father Scheiner then endeavors to make the usual treaty; he promulgates a pseudo-scientific theory—a statement based on a "religious science"—which only provokes derision.
But the war grew more and more bitter, andthe principal weapons in it are worth examining. They are very easily examined; you may pick them up on any of the battle-fields of science; but on that field they were used with more effect than on almost any other. These weapons are two epithets: "Infidel" and "Atheist."
The battle-fields of science are thickly strewn with these. They have been used against almost every man who has ever done anything new for his fellow-men. The list of those who have been denounced as infidel and atheist includes almost all great men of science—general scholars, inventors, philanthropists. The deepest Christian life, the most noble Christian character, have not availed to shield combatants. Christians like Isaac Newton and Pascal and John Locke and John Milton, and even Howard and Fénelon, have had these weapons hurled against them. Of all proofs of the existence of a God, those of Descartes have been wrought most thoroughly into the minds of modern men; and yet the Protestant theologians of Holland sought to bring him to torture and to death by the charge of atheism, and the Roman Catholic theologians of France prevented the rendering of any due honors to him at his burial.[48]
These epithets can hardly be classed with civilized weapons. They are burning arrows. They set fire to great masses of popular prejudices; smoke rises to obscure the real questions; fire bursts forth at times to destroy the attacked party. They are poisoned. They go to the hearts of loving women, they alienate dear children; they injure the man after life is ended, for they leave poisoned wounds in the hearts of those who loved him best—fears for his eternal happiness—dread of the Divine displeasure. Of course, in these days, these weapons, though often effective in disturbing good men and in scaring good women, are somewhat blunted. Indeed, they not unfrequently injure assailants more than assailed. So it was not in the days of Galileo; they were then in all their sharpness and venom.
Yet far more vile than the use even of these weapons—vile indeed beyond belief—was the attack by the Archbishop of Pisa.
It is a remark made by one of the most moderate and judicially fair of modern philosophic historians, that, of all organizations this world has known, the Roman Church has caused most undeserved woe and shed most innocent blood; but, in the whole terrible succession of Torquemadas and Arbues and Granvilles, the vilest enemy of the human race is probably this same Archbishop of Pisa.
This man, whose cathedral is more truly consecrated by the remembrance of Galileo's observation of the lamp swinging before its altar, than by all the church services of a thousand years, began a siege against the great philosopher.
Galileo, after his discoveries had been denounced as contrary to Scripture, had been induced to write to the Duchess Christine and to his friend Castelli two letters, to show that his discoveries might be reconciled to Scripture. The archbishop saw his opportunity: he determined to get hold of these letters and exhibit them as proofs that Galileo had uttered heretical views of theology and the Scriptures, and thus to bring the astronomer hopelessly into the clutch of the Inquisition. The archbishop begs Castelli, therefore, to let him see the original letter in the handwriting of Galileo. Castelli declines; the archbishop then, while, as is now revealed, writing constantly and bitterly to the inquisitors against Galileo, professes to Castelli the greatest admiration of Galileo's genius, and a sincere desire to know more of his discoveries. Castelli is seduced by this; but Galileo sturdily forbids sending the letter, and the archbishop is obliged to resort to open attack.
The whole struggle to crush Galileo and to save him would be amusing were it not so fraught with evil. There were intrigues and counter-intrigues, plots and counter-plots, lying and spying,and in the thickest of this seething, squabbling, screaming mass, priests, bishops, archbishops, cardinals, and even the future Pope Urban VIII. himself. It is most suggestive to see in this crisis of the Church, on the eve of the greatest errors in church policy the world has known, in all the efforts and deliberations of these consecrated leaders of the Church, at the tomb of the Prince of the Apostles, no more sign of the guidance or presence of the Holy Spirit than in a caucus of New York politicians.
But the opposing powers were too strong. In 1615 Galileo is summoned by the Inquisition to Rome, and the mine, which had been so long preparing, was sprung. Pope Paul V. and the cardinal inquisitors order eleven theologians of the Inquisition to examine these two propositions which had been extracted from Galileo's letters on the solar spots:First, that the sun does not move about the earth;secondly, that the earth does move about the sun. The eleven theologians solemnly considered these points, and in about a month rendered a solemn decision that "the first proposition,that the sun is the centre, and does not revolve about the earth, is foolish, absurd, false in theology, and heretical, because expressly contrary to Holy Scripture; and that the second proposition, that the earth is not the centre, but revolves about the sun, is absurd, false in philosophy, and,from a theological point of view, at least opposed to the true faith."[49]
The pope himself, Paul V., now intervenes; he orders that Galileo be brought before the Inquisition. Then the great man of science in that age is brought face to face with the greatest theologian: Galileo is confronted by Cardinal Bellarmin. Bellarmin shows Galileo the error of his opinion, and orders him to renounce it. De Lauda, fortified by a letter from the pope, ordering the astronomer to be placed in the dungeon of the Inquisition should he refuse to yield, commands him to "abandon entirely the opinion that the sun is the centre of the universe, and that the earth moves, and to abstain from sustaining, teaching, or defending that opinion in any manner whatever, orally or by writing."[50]
Galileo bowed to this order, was allowed to retire, and the whole proceeding was kept secret.
About ten days later, on March 5, 1616, the Congregation of the Index, moved thereto, as we have seen, and as the letters and documents now brought to light show, by Pope Paul V., solemnly rendered their decree: that the doctrine of the double movement of the earth about its axis and about the sun isfalse and entirely contraryto Holy Scripture; that this opinion must neither be taught nor defended. The same decree condemned the writings of Kopernik, andall writings which affirm the motion of the earth. The great work of Kopernik was interdicted until corrected in accordance with the views of the Inquisition; and the works of Galileo and Kepler, though not mentioned by name, were included among those implicitly condemned as "affirming the motion of the earth."
The condemnations were inscribed upon theIndex, and to the Index was prefixed the usual papal bull giving its monitions the papal sanction. To teach or even read the works denounced or passages condemned, was to risk persecution in this world and damnation in the next. Human science had apparently lost the great decisive battle.
For some time Galileo remained at Rome perfectly submissive.[51]Pope Paul V. petted him, and all seemed happy in the ending of the long war.
But, returning to Florence, something of his old scientific ardor stirred within him; and at last Cardinal Barberini, who had seemed liberal and friendly, having been made pope under the nameof Urban VIII., Galileo conceived new hopes, and again in a published work alluded favorably to the Copernican system. New troubles ensued. Galileo was induced to visit Rome again, and Pope Urban tried to cajole him into silence, and personally took the trouble to try to show the astronomer his errors by argument. Other opponents were less considerate. Works appeared attacking his ideas—works all the more unmanly, since their authors knew how Galileo was restrained by force from defending himself; and, as if to accumulate proofs of the fitness of the Church to take charge of advanced instruction, his salary as professor at the University of Pisa was taken from him. Sapping and mining began. Just as the Archbishop of Pisa some years before had tried to betray Galileo with honeyed words to the Inquisition, so now Father Grassi tried it; and after various attempts to draw him out by flattery, suddenly denounced his scientific ideas as "leading to a denial of the real presence in the Eucharist."
And here science again loses ground. Galileo had announced his intention of writing upon the theory of the tides, but he retreated, and thus was lost a great treatise to the world.
For the final assault, the park of heavy artillery was at last wheeled into place. You see it on all the scientific battle-fields. It consists of generaldenunciation; and Father Melchior Inchofer, of the Jesuits, brought his artillery to bear well on Galileo with this declaration: that the opinion of the earth's motion is, of all heresies, the most abominable, the most pernicious, the most scandalous; that the immobility of the earth is thrice sacred; that argument against the immortality of the soul, the Creator, the incarnation, etc., should be tolerated sooner than an argument to prove that the earth moves.[52]
But this state of things could not be endured forever. Urged beyond forbearance, Galileo prepares a careful treatise in the form of a dialogue, exhibiting the arguments for and against the Copernican and Ptolemaic systems. He then offers to submit to any conditions the Church tribunals may impose, if they will but allow it to be printed. At last they consent, imposing the most humiliating condition of all, which was a preface written by Father Ricciardi and signed by Galileo, in which the whole work was virtually exhibited as a play of the imagination, and not at all as opposed to the truth laid down in 1616 by the Inquisition.
The new work met with prodigious success; it put new weapons into the hands of the supporters of the Copernican theory. The preface only embittered the contest; it was laughed at from oneend of Europe to the other as ironical. This aroused the enemy. The Jesuits, Dominicans, and the great majority of the clergy, returned to the attack more violent than ever; and Pope Urban VIII., his personal pride being touched, after some halting joined the clerical forces.
The first important piece of strategy was to forbid the sale of the work; but the first edition had already been exhausted and spread throughout Europe. Urban now became angry, and both Galileo and his works were placed in the hands of the Inquisition. In vain did the good Benedictine Castelli urge that Galileo was entirely respectful to the Church; in vain did he say that "nothing that could be done could now hinder the earth from revolving." He was dismissed, and Galileo was forced to appear in the presence of the dread tribunal without defender or adviser. There, as was so long concealed but as is now fully revealed, he was menaced with torture by express order of Pope Urban, and, as is now thoroughly established by documentary evidence, forced to abjure under threats, and subjected to imprisonment by command of Urban, the Inquisition deferring in the most servile manner to the papal authority.
The rest of the story the world knows by heart; none of the recent attempts have succeeded in mystifying it. The whole world will remember forever how Galileo was subjected certainly toindignity and imprisonment equivalent to physical torture;[53]how he was at last forced to pronounce publicly, and on his knees, his recantation as follows: "I, Galileo, being in my seventieth year, being a prisoner and on my knees, and before your eminences, having before my eyes the Holy Gospel, which I touch with my hands, abjure, curse, and detest the error and the heresy of the movement of the earth."
He was vanquished indeed, for he had been forced, in the face of all coming ages, to perjure himself; and, to complete his dishonor, he was obliged to swear to denounce to the Inquisition any other man of science whom he should discover to be supporting heresy—the "heresy of the movement of the earth."
Nor was this all. To the end of his life, nay, after his life was ended, this bitter persecution was continued, on the supposition that the great truths he revealed were hurtful to religion. After a brief stay in the dungeons of the Inquisition, he was kept in exile from family, friends, all his noble employments, and held rigidly to his promise not even to speak of his theory. When,in the midst of intense bodily sufferings from disease and mental sufferings from calamities in his family, he besought some little liberty, he was met with threats of a recommittal to his dungeon. When, at last, a special commissioner had reported to the ecclesiastical authorities that Galileo had become blind and wasted away with disease and sorrow, he was allowed but little more liberty, and that little tempered by the close surveillance of the ecclesiastical authorities. He was forced to bear contemptible attacks on himself and on his works in silence; he lived to see his ideas carefully weeded out from all the church colleges and universities in Europe; and when, in a scientific work, he happened to be spoken of as "renowned," the Inquisition ordered the substitution of the word "notorious."[54]
Nor did the persecution cease with his death. Galileo had begged to be buried in his family tomb in Santa Croce; the request was denied: his friends wished to erect a monument over him; this, too, was refused. Pope Urban said to the embassador Niccolini that "it would be an evil example for the world if such honors were rendered to a man who had been brought before the Roman Inquisition for an opinion so false and erroneous, who had communicated it to manyothers, and who had given so great a scandal to Christendom."[55]
In accordance, therefore, with the wish of the pope and the orders of the Inquisition, Galileo was buried ignobly, apart from his family, without fitting ceremony, without monument, without epitaph. Not until forty years after did Pierozzi dare to write his epitaph. Not until a hundred years after did Nelli dare transfer his remains to Santa Croce and erect above them a suitable monument. Even then the old conscientious hostility burst out: the Inquisition was besought to prevent such honors to "a man condemned for notorious errors;" and that tribunal refused to allow any epitaph to be placed above him which had not first been submitted to its censorship. Nor has that old conscientious consistency in hatred yet fully relented; hardly a generation since has not seen some Marini, or De Bonald, or Rallaye, or De Gabriac, suppressing evidence, or torturing expressions, or inventing theories, to blacken the memory of Galileo and save the reputation of the Church.[56]
The action of the Church authorities corresponded well to the spirit thus exhibited; not until 1757, over one hundred years after his condemnation, was it removed, and then secretly; not until 1835, over two hundred years after his condemnation, was the record of it expunged from theIndex.
But this is by no means the only important part of this history. Hardly less important, for one who wishes to understand the character of the warfare of science, is it to go back over those two hundred years between that fearful crime and its acknowledgment, and study the great retreat of the army of the Church after its disastrous victory over Galileo.
Having gained this victory, the conscientious believers in the Bible as a compendium of history and text-book of science exulted greatly. Loud was the rejoicing that the "heresy," the "infidelity," the "atheism," involved in believing that the earth revolves about its axis and moves around the sun, had been crushed by the great tribunal of the Church, acting in strict obedience to the expressed will of one pope and the written order of another.
But soon clear-sighted men saw that this victory was a disaster. From all sides came proofs that Kopernik and Galileo were right; and although Pope Urban and the Inquisition held Galileo instrict seclusion, not allowing him even tospeakregarding the double motion of the earth; and although the condemnation of "all books which affirm the motion of the earth" was kept on the Index; and although the colleges and universities under Church control were compelled to teach the opposite doctrine, it was seen that the position gained by the victory over Galileo could not be maintained for ever. So began the great retreat—the retreat of the army of Church apologists through two centuries of sophistry, trickery, and falsehood.
The first important move in the retreat was a falling back upon the statement that Galileo was condemned, not because he affirmed the motion of the earth, but because he supported it from Scripture. For a considerable time this falsehood served its purpose; even a hundred and fifty years after Galileo's condemnation it was renewed by the Protestant Mallet du Pan,[57]in his wish to gain favor from the older Church; but the slightest critical examination of the original documents, recently revealed, show this position utterly untenable. The letters of Galileo to Castelli and the Grand-duchess Christine, in which he spoke of the Copernican theory as reconcilable with Scripture, were not published until after the condemnation; and although the Archbishop of Pisa hadendeavored to use them against him, they were but casually mentioned in 1616, and entirely left out of view in 1633. What was condemned in 1616 as "absurd, false in theology, and heretical, because absolutely contrary to Holy Scripture," was the proposition that "the sun is the centre about which the earth revolves;" and what was condemned as "absurd, false in philosophy, and, from a theologic point of view at least, opposed to the true faith," was the proposition that "the earth is not the centre of the universe and immovable, but has a diurnal motion."[58]
What Galileo was made, by express order of Pope Urban and by the action of the Inquisition under threat of torture, to abjure, was "the error and heresy of the movement of the earth."[59]
What theIndex, prefaced by papal bulls binding its contents upon the consciences of the faithful, for two hundred years steadily condemned, were "all books which affirm the motion of the earth."
Not one of these condemnations was directed against Galileo's private letters to Castelli and Christine affirming the possibility of reconciling his ideas to Scripture.
Having been dislodged from this point, theChurch apologists sought cover under the statement that "Galileo was condemned not for heresy, but for contumacy," and for "wanting in respect for the pope."[60]
As to the first point, the very language of the various sentences shows the falsehood of the assertion; they speak of "heresy," and never of "contumacy." As to the last point, the display of the original documents settled that forever. It was proved by them that from first to last he had been toward the pope most patient and submissive. He had indeed expressed his anger at times against his traducers; but to hold this the cause of the judgment against him, is to degrade the whole proceeding, and to convict the pope, Bellarmin, the theologians, and the Inquisition, of direct falsehood, since they assigned entirely different reasons for their conduct. From this, therefore, the apologists hastily retreated.
The next rally was made about the statement that the persecution of Galileo was the result of a quarrel between Aristotelian professors on one side and professors favoring the experimental method on the other, and that at first Pope Urban favoredGalileo. But this position was attacked and carried by a very simple statement. If the Divine guidance of the Church is such a sham that it can be dragged into a professional squabble, and the pope made the tool of a faction in bringing about a most disastrous condemnation of a proven truth, how does the Church differ from any human organization sunk into decrepitude, managed by simpletons and controlled by schemers? If the argument be true, the condition of the Church is worse than its enemies have declared it. Amid the jeers of an unfeeling world the apologists sought new shelter.
The next point at which a stand was made was the assertion that the condemnation of Galileo was "provisory;" but this proved a more treacherous shelter than the other. When doctrines have been solemnly declared, as those of Galileo were solemnly declared, "contrary to the sacred Scriptures," "opposed to the true faith," and "false and absurd in theology and philosophy," to say that such declarations are "provisory,"[61]is to say that the truth held by the Church is not immutable; from this, then, the apologists retreated.
While this retreat was going on, there was a constant discharge of small-arms in the shape of innuendoes, hints, and small sophistries, by smallwriters; every effort was made to blacken Galileo's private character; the irregularities of his early life were dragged forth, and stress was laid on breaches of etiquette; but this succeeded so poorly, that in 1850 it was thought necessary by the Roman court to cover their retreat by some more careful strategy.
The original documents of the trial of Galileo had, during the storms of the early part of the century, been transferred to Paris; but after several years, in 1846, they were returned to Rome by the French government, on the express promise by the papal authorities that the decisions should be published. After various delays, on various pretexts, in 1850 the long-expected publication appeared. The ecclesiastic charged with presenting them to the world was Monsignor Marini. This ecclesiastic was of a kind which has too often afflicted the weary earth—fox-like in cunning, cat-like in treachery. Despite the solemn promise of the papal court, the wily Marini became the instrument of the Roman authority in evading the promise; by suppressing a document here, and interpolating a statement there, he managed to give plausible standing-ground for nearly every important sophistry ever broached to save the reputation of the Church and destroy the reputation of Galileo. He it was who supported the idea that "Galileo was condemned not for heresy,but for contumacy," and various other assertions as groundless.
The first effect of Monsignor Marini's book seemed favorable in covering the retreat of the Church; aided by him, such vigorous writers as Ward were able to throw up temporary intrenchments between the Church and the indignation of the world.
But some time later came an investigator very different from wily Monsignor Marini. This man was a Frenchman, M. de l'Epinois. Like Marini, de l'Epinois was devoted to the Church, but, unlike Marini, he could not lie. Having obtained access, in 1867, to the Galileo documents at the Vatican, he published fully all those of importance, without suppression or piously-fraudulent manipulation. This made all the intrenchments based upon Marini's statements untenable. Another retreat had to be made.
And now was made the most desperate effort of all. The apologistic army, reviving an idea which popes and Church had spurned, declared that the pope,as pope, had never condemned the doctrines of Kopernik and Galileo; that he had condemned them as a man simply; that therefore the Church had never been committed to them; that they were condemned by the cardinals of the Inquisition and Index, and that the pope had evidently been restrained from signing their condemnationby Providence.[62]Nothing could show the desperation of the retreating party better than jugglery like this. The facts are, that from Pope Urban downward, among the Church authorities of the seventeenth century, the decision was spoken of as made by the pope and the Church. Urban VIII. spoke of that of 1616 as made by Pope Paul V. and the Church, and of that of 1633 as made by himself and the Church.[63]
When Gassendi attempted to raise the point that the decision was not sanctioned by the Church as such, a great theological authority, Father Lecazre, rector of the College of Dijon, publicly contradicted him, and declared that it "was not certain cardinals, but the supreme authority of the Church," that had condemned Galileo; and to this statement the pope and the Church gave consent, either openly or by silence.[64]The suspected thinkers, like Descartes and others, who attempted to raise the same point, were treated with contempt. Father Castelli, who had devoted himself to Galileo, and knew to his cost just what the condemnation meant and who made it, takes it for granted, in his letter to the papal authorities, that it was made by the Church. Cardinal Querenghiin his letters, the embassador Guicciardini in his dispatches, the historian Viviani in his biography of Galileo—all writing under Church inspection at the time—take the view that the Church condemned Galileo. The Inquisition itself, backed by the greatest theologian of the time, Bellarmin, took the same view;[65]and if this were not enough, we have the Roman Index, containing the condemnation for nearly two hundred years, prefaced by a solemn bull of the reigning pope, binding the condemnation on the consciences of the whole Church, and reiterating year after year the condemnation of "all books which affirm the motion of the earth" as damnable.[66]To attempt to face all this, added to the fact that the Inquisition condemned Galileo, and required his abjuration of "the heresy of the movement of the earth" by written order of the pope, was soon seen to be impossible.
