The Freedom of Science

Obedience of Faith and Injury to Science

While all this is true, yet one may not share this conviction, nor rise to the certainty that there is a supernatural world whence the Son of God descended to teach man and to found an infallible Church. Still, to be fair, he must admit that no real danger to freedom of research and progress of science results from submission to faith, as shown above.

In the first place it must be admitted that the assertion is still unproved, that a positive result of research has ever come in hopeless conflict with a dogma of faith; hence that science has been prevented from accepting this result. No such case can be found. The condemnation of the Copernican view of the world will be considered presently; we pass over the fact that at the time of its condemnation it was not a positive result of science: the main point is that the condemnation was not an irrevocable dogma of faith, but only the decision of a Congregation, which was withdrawn as soon as the truth was clearly demonstrated. Besides, science has suffered no injury from that decision.

In general, where there is real contradiction between science and faith, the matters in question are invariably hypotheses. Is it more than an hypothesis, and a very doubtful hypothesis at that, that the world and God are identical, that there is an eternal, uncreated course of the world, that miracles are impossible? That what is said about the natural origin of Christianity, the origin of the Jewish religion from Babylonian myths, the origin of all religions from fear, fancy, or deception, is it anything more than hypothetical? The false systems of knowledge, subjectivism, and agnosticism – are they more than hypotheses? Ask their originators and champions; they will admit it themselves; and if they will not admit it, others will tell them that their propositions are not only hypotheses, but often quite untenable. There is hardly a single hypothesis which has not its vehement opponents. That the serious conflict between dogma and science is waged only in this field could be proved by abundant examples. Besides, is it not the philosophical axiom of modern freedom of thought, that in the sphere of philosophy and religion there is no certain knowledge, but only supposition?

Can hypotheses claim to rank as assured results of research which should be universally accepted? Why should it not be allowed to contradict them, to oppose them with other suppositions? Is it not in the interest of science that this be done, that they be subjected to sharp criticism, lest they gradually be given out for positive results? Is it not a shameful trifling with the truth, when a Haeckel deceives wide circles by pretending that most frivolous hypotheses are established results of science? Is it not misleading when modern science treats the rejection of a supernatural order as an established principle?

And how often the hypotheses of profane sciences change! “Laymen are astonished,” says H. Poincaré, “that so many scientific theories are perishable. They see them thrive for a few years, to be abandoned one after the other; they see wrecks heaped upon wrecks; they foresee that theories now fashionable will after a short while be forgotten, and they conclude that these theories are absolute fallacy. They call it the bankruptcy of science” (Wissenschaft u. Hypothese, German by F. Lindemann, 2d ed., 1906, 161). The conclusion is certainly unjustified, but the fact itself remains. Is it then a loss to science when faith opposes in the field of religion these variations of opinion with fixed dogmas?

Or are these perhaps of less worth, or less certain than their contraries? Is the dogma of the existence of God of less value than atheism? Is the conviction of the existence of a world of spirits less substantial than the philosophy of materialistic monism? Is the doctrine of the origin of the human soul from the creating hand of God found inferior to the notion that the soul has developed from the lower stages of animal life? Should the holy teaching of Christianity, doctrines believed by the best periods in the world's history, believed in and professed by minds like those of an Augustine, a Thomas, and a Leibnitz; doctrines that since their appearance on earth have always attracted the noble and good, and repelled chiefly the base and immoral; doctrines that still wait for their first unobjectionable refutation – should such doctrines be less sure than the innumerable, ever-changing suggestions of unregulated thought, apparently directed by an aversion to everything supernatural?

Erravimus

Yet another fact may be pointed out. It is an undeniable fact that science, after straying for some time, is not unfrequently compelled to return to what is taught by faith and the Church, thus confirming the truth of the faith. Frequently the new theory has come on like a tornado, sweeping all minds before it. But the tempest was soon spent, the minds recovered their balance and the hasty misjudgment was recognized.

Not long ago, when materialism revelled in its orgies, especially in Germany, when Vogt, Buechner, and Moleschott were writing their books, and science with Du Bois-Reymond was hunting Laplace's theory in the evolution of the world, the Syllabus, undaunted, put its anathema upon the (58.) proposition: “No other forces are acknowledged but those of matter.” The summer-night's dream came to an end, and people rubbed their eyes and saw the reality they had lost a while. The materialism of the 60's and 70's has been discarded by the scientific world, and finds a shelter only in the circles of unschooled infidelity. J. Reinke, in the name of biology, bears testimony in the words: “In my opinion materialism has been disposed of in biology; if, nevertheless, a number of biologists still stand by its colours, this tenacity may be explained psychologically; for, in the apt words of Du Bois-Reymond, in the domain of ideas a man does not willingly and easily forsake the highway of thought which his entire mental training has opened up” (Einleitung in die theoretische Biologie, 1901, 52).

A few decades ago a number of scientists declared it impossible that the different races could have descended from one pair of ancestors, as taught by faith: the difference between the various families being too great and radical, it was said; the difference being rather of species than of race. Moreover, there was announced the discovery of people without religion, without notions of morality and family life; of tribes incapable of civilization and culture; it was asserted in the early days of Darwin enthusiasm that there had been discovered a race of men that clearly belonged to the species ape. Assertions of this kind have gradually ceased. Now the different human races are considered to belong to the same species, and their common parentage is considered possible from the view-point of the theory of evolution. The anthropologist Ranke expresses his opinion thus: “We find the bodily differences perfectly connected by intermediate forms, graded to a nicety, and the summary of the differences appears to point to but one species… This is the prevalent opinion of all independent research of anatomically schooled anthropologists” (Der Mensch, 2d ed., II, 1894, 261). Ethnology denies the existence of nations or tribes without religion (Ratzel, Voelkerkunde, I, 1885, 31). Peschel says: “The statement that any nation or tribe has ever been found anywhere on earth without notions and suggestions of religion can be denied emphatically”(O. Peschel, Voelkerkunde, 6th ed., 1885, 273). “The more recent ethnology knows of no tribes without morality, nor does history record any” (W. Schneider, Die Naturvoelker, 1886, II, 348).

Until a short time ago it was believed that the derivation of man's life from inferior stages of animal life would not be difficult to prove; but at present, while many still adhere to the theory that man has developed from the brute, the conviction is steadily gaining ground that it cannot be scientifically proved and that it becomes more and more difficult to disprove man's higher origin. Unable to withstand the force of facts, one hypothesis gives place to another: what had to be found could not be found, living or extinct links between the brute and man refused to appear anywhere, and those which people thought they had found, turned out to be unsuitable. Kohlbrugge concludes his criticism of the recent theories of the evolution of the body of man from lower animals with the confession: “The above summary is enough to convince everybody that we do not know anything distinct about the great problem of evolution; we have not yet seen its face. All must be done over again” (Die Morpholog. Abstammung des Menschen, 1908, 88). Virchow said at the anthropological congress of Vienna, 1889: “When we met at Innsbruck twenty years ago Darwinism had just finished its first triumphal march through the world, and my friend Vogt became its ardent champion. We have searched in vain for the missing link connecting man directly with the ape.”

What has become of those anatomic-morphologic links between man and beast, the pithecanthropus erectus, the man dug out at Neandertal, Spy, Schipka, La Naulette, and Krapina, and shown with great confidence to the world? What has become of the prehistoric man, said to belong to the glacial period of Europe, and to have ranked far below the present man? J. Kohlmann writes: “I wish to state that I thoroughly adhere to the theory of evolution, but my own experience has led me to the result that man has not changed his racial characteristics since the glacial period. He appears on the soil of Europe physically complete, and there is no ape-man to be found” (apud Ranke, Ibid. 480). Prof. Branco, director of the Palæontological Institute of Berlin, says: “Palæontology tells us nothing about the missing link. This science knows of no ancestors of man” (at the 5th international Zoological Congress, 1901, Wasmann, Die mod. Biolog. 3, p. 488). And the palæontologist Zittel says: “The missing link between man and ape, though a postulate of the theory of evolution, has not been found”(Ranke, l. c. 504). E. Grosse concludes his studies on evolution with the significant words: “I began this book with the intention of writing a history of the evolution of the family, and I finish it convinced that at present the writing of that history is impossible for me or for anybody else” (Die Formen der Familie, 1896, Vorwort). Ranke is perfectly right in saying that “it behoves the dignity of science to confess that it knows nothing of the origin of man” (Thuermer V, 1902, I. Heft).

A century ago or so, ridicule was heaped in the name of science on the description in the Bible of the last day: “The stars shall fall,” “and the powers of heaven shall be moved,” “the elements shall be melted with heat, and the earth shall be burnt up” (Matt. xxiv. 29 seq.; Luke xxi. 25 seq.; Mark xiii. 24 seq.; 2 Pet. iii. 10). Then the assertion that stones could fall from the skies caused a smile, but now science has come to the general knowledge that this is not only possible, but perhaps really will be the end of all things, if once our earth on its journey through unknown spaces of the universe should collide with a comet or get into a cosmic cloud of large meteors. (Cf. the graphic description in K. Braun, Ueber Kosmogonie, 3d ed., 1905, p. 381 seq.)

An example of another kind: It is not so long since Protestant, liberal Bible-criticism and its history of early Christian literature, in the endeavour to remove everything supernatural from the beginning of Christianity, regarded the New Testament and the oldest Christian documents as unreliable testimony, even forgeries, and for this reason placed the date of their origin as late as possible. But now they have to retrace their steps.

A. Harnack writes: “There was a period – the general public is still living in it – when the New Testament and the oldest Christian literature were thought to be but a tissue of lies and forgeries. This time has passed. For science it was an episode in which much was learned of which much must be forgotten. The result of subsequent research over-reaches in a ‘reactionary’ effect what might be termed the central position of modern criticism. The oldest literature of the Church is in the main and in most details true and reliable, that is, from the literary and historical point of view… I am not afraid to use the word ‘retrogressive’ – for we should call a spade a spade – the criticism of the sources of the earliest Christianity is beyond doubt moving retrogressively towards tradition” (Chronologie der Alt-Christ. Literatur I, 1897, VIII). In a more recent work the same savant writes: “During the years from 30 to 70 all originated in Palestine, or, better, in Jerusalem, what later on was developed. This knowledge is steadily gaining and replacing the former ‘critical’ opinion that the fundamental development had extended over a period of about a hundred years”(Lukas der Arzt, 1906, Vorwort). This retrogression is continued still farther in his later work, “Neue Untersuchungen zur Apostolgesch. u. zur Abfassungszeit der synopt. Evang., 1911,” in which Harnack draws very near to the Catholic view regarding the date of writing of the Acts of the Apostles, as also regarding St. Paul's attitude towards Judaism and Christian-Judaism, and departs from the modern Protestant view (cf. pp. 28-47, 79 seq., 86, 93 seq.). “Protestant authorities on church-history,” he says elsewhere, “no longer take offence at the proposition that the main elements of Catholicism go back to the Apostolic era, and not only peripherically” (Theol. Literar. Zeitung, 1905, 52).

In a speech, much commented on, which he made at his university January 12, 1907, Prof. Harnack, discussing the religious question in Germany, called attention to the fact that there has been quite a marked return to the Catholic standpoint: “From the study of Church history we find that we all have become different from what our fathers were, whether we may like it or not. Study has shown that we are separated from our fathers by a long course of development; that we do not understand their ideas and words at all, much less do we use them in the sense they used them.” He then draws out the comparison more particularly: “Flacius and the older Protestants denied that Peter had ever been in Rome at all. Now we know that his having been there is a fact well evidenced in history.” The motto of the older Protestants was that the Scriptures are the sole source of revelation. “But now, and for a long time past, Protestant savants have realized that the Scriptures could not be separated from tradition, and that the collecting of the New Testament Scriptures was a part of tradition.” “Protestants of the sixteenth century taught justification by faith alone, without works. In the absence of confessional controversy, no evangelical Christian would now find fault with the teaching which declares only such faith to be of any worth which shows itself by the love of God and of the neighbour” (Protestantismus u. Katholizismus in Deutschland, Preussisch. Jahrbücher 127. Bd., 1907, 301 seq.).

Many similar instances of science confessing Erravimus in regard to the Christian or Catholic position could be cited. They are an admonition to be modest, not to overrate the value of a scientific proposition, and not, with supreme confidence and infallibility, to brand it as an offence against the human intellect to let one's self be guided by the principles of faith.

Moreover, it has often happened that science emphatically and sneeringly rejected propositions, and called them false and absurd, which to-day are considered elementary.

Newton, in 1687, had correctly explained the revolution of the moon around the earth, and of the planets around the sun, as the co-operation of gravitation and inertia, and thence concluded also the elliptic form of the orbits of planets previously discovered by Kepler. Leibnitz rejected this theory, Huygens called it absurd, and the Academy of Paris as late as 1730 still favoured the theory of revolution of Descartes; it was only about the year 1740 that it was generally accepted. Huygens, himself, had formed in 1690 his theory about light-waves. For a long time it was misunderstood. Only in 1800, or somewhat later, it received its merited acknowledgment, but noted physicists like Biot and Brewster rejected it still for some time and held to the theory of emission. “Even in the intellectual world the law of inertia holds good” (Rosenberger, Gesch. der Physik, III, 1887, 139).
