“I regard the universe as the one fact, as the one existence -- that is, as the absolute thing. I am a part of this. I do not say that there is no God; I simply say that I do not believe there is. There may be millions of them. Neither do I say that man is not immortal. Upon that point I admit that I do not know, and the declarations of all the priests in the world upon that subject give me no light, and do not even tend to add to my information on the subject, because I know that they know that they do not know.”
