5. Still more rousing, finally, was the effect of the science of zoology, as placed upon a broad scientific foundation by Charles Darwin. Here again steps had been taken in previous generations on the right path, without any general movement on the part of scientific and educated men. Darwin’s own grandfather, Erasmus Darwin, had in his Zoonomia (1794) anticipated many of the positions of the French Lamarck, who in 1801 began developing the views he fully elaborated in 1815, as to the descendance of all existing species from earlier forms.[245] As early as 1795 Geoffroy Saint-Hilaire had begun to suspect that all species are variants on a primordial form of life; and at the same time (1794–95) Goethe in Germany had reached similar convictions.[246] That views thus reached almost simultaneously in Germany, England, and France, at the time of the French Revolution, should have to wait for two generations before even meeting the full stress of battle, must be put down as one of the results of the general reaction. Saint-Hilaire, publishing his views in 1828, was officially overborne by the Cuvier school in France. In England, indeed, so late as 1855, we find Sir David Brewster denouncing the Nebular Hypothesis: “that dull and dangerous heresy of the age.... An omnipotent arm was required to give the planets their position and motion in space, and a presiding intelligence to assign to them the different functions they had to perform.”[247] And Murchison the geologist was no less emphatic against Darwinism, which he rejected till his dying day (1871).

6. Other anticipations of Darwin’s doctrine in England and elsewhere came practically to nothing,[248] as regarded the general opinion, until Robert Chambers in 1844 published anonymously his Vestiges of the Natural History of Creation, a work which found a wide audience, incurring bitter hostility not only from the clergy but from some specialists who, like Huxley, were later to take the evolutionist view on Darwin’s persuasion. Chambers it was that brought the issue within general knowledge; and he improved his position in successive editions. A hostile clerical reader, Whewell, admitted of him, in a letter to a less hostile member of his profession, that, “as to the degree of resemblance between the author and the French physiological atheists, he uses reverent phrases: theirs would not be tolerated in England”; adding: “You would be surprised to hear the contempt and abhorrence with which Owen and Sedgwick speak of the Vestiges.”[249] Hugh Miller, himself accused of “infidelity” for his measure of inductive candour, held a similar tone towards men of greater intellectual rectitude, calling the liberalizing religionists of his day “vermin” and “reptiles,”[250] and classifying as “degraded and lost”[251] all who should accept the new doctrine of evolution, which, as put by Chambers, was then coming forward to evict his own delusions from the field of science. The young Max Müller, with the certitude born of an entire ignorance of physical science, declared in 1856 that the doctrine of a human evolution from lower types “can never be maintained again,” and pronounced it an “unhallowed imputation.”[252]

7. “Contempt and abhorrence” had in fact at all times constituted the common Christian temper towards every form of critical dissent from the body of received opinion; and only since the contempt, doubled with criticism, began to be in a large degree retorted on the bigots by instructed men has a better spirit prevailed. Such a reaction was greatly promoted by the establishment of the Darwinian theory. It was after the above-noted preparation, popular and academic, and after the theory of transmutation of species had been definitely pronounced erroneous by the omniscient Whewell,[253] that Darwin produced (1859) his irresistible arsenal of arguments and facts, the Origin of Species, expounding systematically the principle of Natural Selection, suggested to him by the economic philosophy of Malthus, and independently and contemporaneously arrived at by Dr. Alfred Russel Wallace. The outcry was enormous; and the Church, as always, arrayed itself violently against the new truth. Bishop Wilberforce pointed out in the Quarterly Review that “the principle of natural selection is absolutely incompatible with the word of God,”[254] which was perfectly true; and at a famous meeting of the British Association in 1860 he so travestied the doctrine as to goad Huxley into a fierce declaration that he would rather be a descendant of an ape than of a man who (like the Bishop) plunged into questions with which he had no real acquaintance, only to obscure them and distract his hearers by appeals to religious prejudice.[255] The mass of the clergy kept up the warfare of ignorance; but the battle was practically won within twenty years. In France, Germany, and the United States leading theologians had made the same suicidal declarations, entitling all men to say that, if evolution proved to be true, Christianity was false. Professor Luthardt, of Leipzig, took up the same position as Bishop Wilberforce, declaring that “the whole superstructure of personal religion is built upon the doctrine of creation”;[256] leading American theologians pronounced the new doctrine atheistic; and everywhere gross vituperation eked out the theological argument.[257]

8. Thus the idea of a specific creation of all forms of life by an originating deity—the conception which virtually united the deists and Christians of the eighteenth century against the atheists—was at length scientifically exploded. The principle of personal divine rule or providential intervention had now been philosophically excluded successively (1) from astronomy by the system of Newton; (2) from the science of earth-formation by the system of Laplace and the new geology; (3) from the science of living organisms by the new zoology. It only needed that the deistic conception should be further excluded from the human sciences—from anthropology, from the philosophy of history, and from ethics—to complete, at least in outline, the rationalization of modern thought. Not that the process was complete in detail even as regarded zoology. Despite the plain implications of the Origin of Species, the doctrine of the Descent of Man (1871) came on many as a shocking surprise and evoked a new fury of protest. The lacunæ in Darwin, further, had to be supplemented; and much speculative power has been spent on the task by Haeckel, without thus far establishing complete agreement. But the desperate stand so long made on the score of the “missing link” seems to have been finally discredited in 1894; and the Judæo-Christian doctrine of special creation and providential design appears, even in the imperfectly educated society of our day, to be already a lost cause.

As we have seen, however, it was not merely the clerical class that resisted the new truth: the men of science themselves were often disgracefully hostile; and that “class” continued to give a sufficiency of support to clericalism. If the study of the physical sciences be no guarantee for recognition of new truth in those sciences, still less is it a sure preparation for right judgment in matters of sociology, or, indeed, for a courageous attitude towards conventions. Spencer in his earlier works used the language of deism[258] at a time when Comte had discarded it. It takes a rare combination of intellectual power, moral courage, and official freedom to permit of such a directly rationalistic propaganda as was carried on by Professor Clifford, or even such as has been accomplished by President Andrew White in America under the comparatively popular profession of deism. It was only in his leisured latter years that Huxley carried on a general conflict with orthodoxy. In middle age he frequently covered himself by attacks on professed freethinkers; and he did more than any other man of his time in England to conserve the Bible as a school manual by his politic panegyric of it in that aspect at a time when bolder rationalists were striving to get it excluded from the State schools.[259] Other men of science have furnished an abundance of support to orthodoxy by more or less vaguely religious pronouncements on the problem of the universe; so that Catholic and other obscurantist agencies are able to cite from them many quasi-scientific phrases[260]—taking care not to ask what bearing their language has on the dogmas of the Churches. Physicists who attempt to be more precise are rarely found to be orthodox; and the moral and social science of such writers is too often a species of charlatanism. But the whole tendency of natural science, which as such is necessarily alien to supernaturalism, makes for a rejection of the religious tradition; and the real leaders of science are found more and more openly alienated from the creed of faith. We know that Darwin, though the son and grandson of freethinkers, was brought up in ordinary orthodoxy by his mother, and “gave up common religious belief almost independently from his own reflections.”[261] All over the world that has since been an increasingly common experience among scientific men.

Section 5.—The Sociological Sciences

1. A rationalistic treatment of human history had been explicit or implicit in the whole literature of Deism; and had been attempted with various degrees of success by Bodin, Vico, Montesquieu, Mandeville, Hume, Smith, Voltaire, Volney, and Condorcet, as well as by lesser men.[262] So clear had been the classic lead to naturalistic views of social growth in the Politics of Aristotle, and so strong the influence of the new naturalistic spirit, that it is seen even in the work of Goguet (1769), who sets out as biblically as Bossuet; while in Germany Herder and Kant framed really luminous generalizations; and a whole group of sociological writers rose up in the Scotland of the middle and latter parts of the century.[263] Here again there was reaction; but in France the orthodox Guizot did much to promote broader views than his own; Eusèbe Salverte in his essay De la Civilisation (1813) made a highly intelligent effort towards a general view; and Charles Comte in his Traité de Législation (1826) made a marked scientific advance on the suggestive work of Herder. As we have seen, the eclectic Jouffroy put human affairs in the sphere of natural law equally with cosmic phenomena. At length, in the great work of Auguste Comte, scientific method was applied so effectively and concretely to the general problem that, despite his serious fallacies, social science again took rank as a solid study.

2. In England the anti-revolution reaction was visible in this as in other fields of thought. Hume and Gibbon had set the example of a strictly naturalistic treatment of history; and the clerical Robertson was faithful to their method; but Hallam makes a stand for supernaturalism even in applying a generally scientific critical standard. The majority of historical events he is content to let pass as natural, even as the average man sees the hand of the doctor in his escape from rheumatism, but the hand of God in his escape from a railway accident. Discussing the defeat of Barbarossa at Legnano, Hallam pronounces that it is not “material to allege ... that the accidental destruction of Frederic’s army by disease enabled the cities of Lombardy to succeed in their resistance.... Providence reserves to itself various means by which the bonds of the oppressor may be broken; and it is not for human sagacity to anticipate whether the army of a conqueror shall moulder in the unwholesome marshes of Rome or stiffen with frost in a Russian winter.”[264]

But Hallam was nearly the last historian of distinction to vend such nugatory oracles as either a philosophy or a religion of history. Even the oracular Carlyle did not clearly stipulate for “special providences” in his histories, though he leant to that conception; and though Ranke also uses mystifying language, he writes as a Naturalist; while Michelet is openly anti-clerical. Grote was wholly a rationalist; the historic method of his friend and competitor, Bishop Thirlwall, was as non-theological as his; Macaulay, whatever might be his conformities or his bias, wrote in his most secular spirit when exhibiting theological evolution; and George Long indicated his rationalism again and again.[265] It is only in the writings of the most primitively prejudiced of those German historians who eliminate ethics from historiography that the “God” factor is latterly emphasized in ostensibly expert historiography.
