This century will be called Darwin's century. He was one of the greatest men who ever touched this globe. He has explained more of the phenomena of life than all of the religious teachers. Write the name of Charles Darwin on the one hand and the name of every theologian who ever lived on the other, and from that name has come more light to the world than from all of those. His doctrine of evolution, his doctrine of the survival of the fittest, his doctrine of the origin of species, has removed in every thinking mind the last vestige of orthodox Christianity. He has not only stated, but he has demonstrated, that the inspired writer knew nothing of this world, nothing of the origin of man, nothing of geology, nothing of astronomy, nothing of nature; that the Bible is a book written by ignorance--at the instigation of fear. Think of the men who replied to him. Only a few years ago there was no person too ignorant to successfully answer Charles Darwin, and the more ignorant he was the more cheerfully he undertook the task. He was held up to the ridicule, the scorn and contempt of the Christian world, and yet when he died, England was proud to put his dust with that of her noblest and her grandest. Charles Darwin conquered the intellectual world, and his doctrines are now accepted facts. His light has broken in on some of the clergy, and the greatest man who to-day occupies the pulpit of one of the orthodox churches, Henry Ward Beecher, is a believer in the theories of Charles Darwin--a man of more genius than all the clergy of that entire church put together. ...The church teaches that man was created perfect, and that for six thousand years he has degenerated. Darwin demonstrated the falsity of this dogma. He shows that man has for thousands of ages steadily advanced; that the Garden of Eden is an ignorant myth; that the doctrine of original sin has no foundation in fact; that the atonement is an absurdity; that the serpent did not tempt, and that man did not 'fall.' Charles Darwin destroyed the foundation of orthodox Christianity. There is nothing left but faith in what we know could not and did not happen. Religion and science are enemies. One is a superstition; the other is a fact. One rests upon the false, the other upon the true. One is the result of fear and faith, the other of investigation and reason.
