We who have grown up under the dispensation, so to speak, of the doctrine of evolution, now acknowledged to be the guiding principle in every department of knowledge find it hard to enter into the spirit of that mid-century Sturm and Drang period which resulted upon the publication of Darwin's 'Origin of Species.' This book is the landmark of the century, and commemorates at once the triumph of knowledge, and its failure. The triumph of science in the realm of phenomena, its failure to pierce into the ultimate causes of these phenomena. What a hard fight scientific methods of investigating the phenomena of nature and life had had up to that time, in the teeth of opposition from the less instructed religious world, has been summarized for us in the fascinating pages of Andrew D. White's 'Warfare Between Theology and Science.' One by one, Science won the outposts held by prejudice and conservatism. It had to be admitted that the earth was not flat and that it did not float upon an infinite sea supported on the back of a tortoise. It had to be admitted, even, that it did not occupy the chief seat in the synagogue of the firmament, but went rolling about the sun like any common little asteroid. Finally, the great guns of science were trained upon man himself and he was forced to retire from his lofty position of Lord of Creation to the much more humble one of outcome of creation. To a large proportion of mankind it seemed as if, should these things be admitted as truth, the whole fabric of society must fall to pieces and religion become a mockery. Those who felt so fought, as for their life, against the conclusions of science. There was a large minority, however, which, intellectually constrained to accept the conclusions of science, yet differed much in temperament and were by consequence, affected in very different ways by the new truths. There were men like Matthew Arnold who no longer believed in the revelations of the past, yet who clung to the beauty of religious forms, in despair at the thought of the wilderness life would be without them. There were others like George Eliot, who became positivists, and gained comfort only in the thought of a religion of humanity and an immortality of nothing more tangible than human influence. There were those like William Morris who accepted cheerfully this life as being all and who devoted their energies to making it as lovely as possible and working to make it more lovely for the future. There were still others, like Clifford, entirely hopeless, but who like Childe Roland put the slug horn to their lips, and lived brave, noble lives in the certainty of coming annihilation; a divine melancholy seized upon some, such as we see reflected in much of Tennyson's verse.
