The appearance of my article in the _Deutsche Rundschau_ seems to have caused much headshaking among my friends in Germany, England, and America. Many letters came to me privately, others were sent directly to the publishers. They came chiefly from two sides. Some were of the opinion that I dealt too lightly with the Horseherd; others protested against what I said about the current theory of evolution. The first objection I have sought to make up for in what follows. The other required no answer, for I had I think, in my previous writings, quite clearly and fully explained my attitude in opposition to so-called Darwinism. Some of my correspondents wished peremptorily to deny me the right of passing judgment upon Darwin’s doctrine, because I am not a naturalist by profession. Here we see an example of the confusion of ideas that results from confusion of language. Darwinism is a high-sounding, but hollow and unreal word, like most of the names that end in ism. What do such words as Puseyism, Jesuitism, Buddhism, and now even Pre-Darwinism and Pre-Lamarckism signify? Everything and nothing, and no one is more on his guard against these generalising _termini technici_ than the _heroes eponymi_ himself. What has not been called Darwinism? That the present has come out of the past, has been called the greatest discovery of the nineteenth century. Darwin himself is not responsible for such things. He wished to show how the present has come out of the past, and he did it in such a manner that even the laity could follow him and sincerely admire him. Now, of course, it cannot be denied that if we understand _Darwinism_ to mean Darwin’s close observations concerning the origin of the higher organisms out of lower as well as the variations of individuals from their specific types, caused by external conditions, it would as ill become me to pass either a favourable or unfavourable judgment as it would Darwin to estimate my edition of the Rig-Veda, or a follower of Darwin to criticise my root theory in philology, without knowing the ABC of the science of language. If, however, we speak of Darwinism in the domain of universal philosophical problems, such as, for instance, the creation or development of the world, then we poor philosophers also have no doubt a right to join in the conversation. And if, without appearing too presuming, we now and then dare to differ from Kant, or from Plato or Aristotle, is it mere insolence, or perhaps treason, to differ from Darwin on certain points? This was not the tone assumed by Darwin, giant as he was, even when he spoke to so insignificant a person as myself. I have on a previous occasion published a short letter addressed to me by Darwin (_Auld Lang Syne_, p. 178). Here follows another, which I may no doubt also publish without being indiscreet. * * * * * “ Down, Beckenham, Kent, July 3, 1873.
