" Our civilization is not Christian. It does not come from the skies. It is not a result of "inspiration." It is the child of invention, of discovery, of applied knowledge -- that is to say, of science. When man becomes great and grand enough to admit that all have equal rights; when thought is untrammeled; when worship shall consist in doing useful things; when religion means the discharge of obligations to our fellow-men, then, and not until then, will the world be civilized. "

― Robert G. Ingersoll
