It seems to me impossible for a civilized man to love or worship, or respect the God of the Old Testament. A really civilized man, a really civilized woman, must hold such a God in abhorrence and contempt... In the New Testament, death is not the end, but the beginning of punishment that has no end. In the New Testament the malice of God is infinite and the hunger of his revenge eternal... This frightful dogma, this infinite lie, made me the implacable enemy of Christianity. The truth is that this belief in eternal pain has been the real persecutor.

Where is the soul? . . . I refuse to believe anything of that kind without proof. The idea that, as soon as a man's breath leaves his body, the soul flops out like a chicken's head and flies off into space to find a lodgment where there [are] harps and haloes. Too much for me.

The Old Testament filled this world with tyranny and injustice, and the New gives us a future filled with pain for nearly all of the sons of men. The Old Testament describes the hell of the past, and the New the hell of the future.

The savage prays to a stone that he calls a god, while the Christian prays to a god he calls a spirit, and the prayers of both are equally useful.

The man who does not do his own thinking is a slave, and is a traitor to himself and to his fellow-men.

The greatest test of courage on earth is to bear defeat without losing heart.

You cannot be so poor that you cannot help somebody.
