We can only glance briefly here at the victorious struggle that the idea of evolution has conducted in the last three decades of the nineteenth century. The violent resistance that Darwinism encountered nearly everywhere in its early years was paralysed towards the end of the first decade. In the years 1866-1874 many works were published in which not only were the foundations of the theory scientifically strengthened, but its general recognition was secured by popular treatment of the subject. I made the first attempt in 1866, in my _General Morphology_, to present connectedly the whole subject of evolution and make it the foundation of a consistent Monistic philosophy; and I then gave a popular summary of my chief conclusions in the ten editions of my _History of Creation_. In my _Evolution of Man_ I made the first attempt to apply the principles of evolution thoroughly and consistently to man, and to draw up a hypothetical list of his animal ancestors. The three volumes of my _Systematic Phylogeny_ (1894-1896) contain a fuller outline of a natural classification of organisms on the basis of their stem-history. There have been important contributions to the science of evolution in all its branches in the Darwinian periodical, _Cosmos_, since 1877; and a number of admirable popular works helped to spread the system. However, the most important and most welcome advance was made by science when, in the last thirty years, the idea of evolution penetrated into every branch of biology, and was recognised as fundamental and indispensable. Thousands of new discoveries and observations in all sections of botany, zoology, protistology, and anthropology, were brought forward as empirical evidence of evolution. This is especially true of the remarkable progress of paleontology, comparative anatomy, and embryology, but it applies also to physiology, chorology (the science of the distribution of living things), and œcology (the description of the habits of animals). How much our horizon was extended by these, and how much the unity of our Monistic system gained, can be seen in any modern manual of biology. If we compare them with those that gave us extracts of natural history forty or fifty years ago, we see at once what an enormous advance has taken place. Even the more remote branches of anthropological science, ethnography, sociology, ethics, and jurisprudence, are entering into closer relations with the theory of evolution, and can no longer escape its influence. In view of all this, it is ridiculous for theological and metaphysical journals to talk, as they do, of the failure of evolution and "the death-bed of Darwinism."
