Darwin--greatest of scientists--so great that our time will probably be known as "Darwin's Century"--had not the slightest confidence in any possible phase of the so-called supernatural. This great man left the creed of Christendom without a foundation. He brought as witnesses against the inspiration of the Scriptures such a multitude of facts, such an overwhelming amount of testimony, that it seems impossible to me that any unprejudiced man can, after hearing the testimony, remain a believer in evangelical religion. He accomplished more than all the schools, colleges, and universities that Christianity has founded. He revolutionized the philosophy of the civilized world. The writers who have done most for science have been the most bitterly opposed by the church. There is hardly a valuable book in the libraries of the world that cannot be found on the "Index Expurgatorius." Kant and Fichte and Spinoza were far above and beyond the orthodox-world. Voltaire did more for freedom than any other man, and yet the church denounced him with a fury amounting to insanity--called him an atheist, although he believed not only in God, but in special providence. He was opposed to the church--that is to say, opposed to slavery, and for that reason he was despised. And what shall I say of D'Holbach, of Hume, of Buckle, of Draper, of Haeckel, of Büchner, of Tyndall and Huxley, of Auguste Comte, and hundreds and thousands of others who have filled the scientific world with light and the heart of man with love and kindness? It may be well enough, in regard to art, to say that Christianity is indebted to Greece and Rome for its highest conceptions, and it may be well to add that for many centuries Christianity did the best it could to destroy the priceless marbles of Greece and Rome. A few were buried, and in that way were saved from Christian fury. The same is true of the literature of the classic world. A few fragments were rescued, and these became the seeds of modern literature. A few statues were preserved, and they are to-day models for all the world. Of course it will be admitted that there is much art in Christian lands, because, in spite of the creeds, Christians, so-called, have turned their attention to this world. They have beautified their homes, they have endeavored to clothe themselves in purple and fine linen. They have been forced from banquets or from luxury by the difficulty of camels going through the eyes of needles or the impossibility of carrying water to the rich man. They have cultivated this world, and the arts have lived. Did they obey the precepts that they find in their sacred writings there would be no art, they would "take no thought for the morrow," they would "consider the lilies of the field."
