Nothing could add to the horror of hell, except the presence of its creator, God.

We do not need the forgiveness of God, but of each other and of ourselves.

The first step is for man to cease to be the slave of man. The second, is to cease to be the slave of the monsters of his own creation, the ghosts and phantoms of the air.

If the account given in Genesis is really true, ought we not, after all, to thank this serpent? He was the first schoolmaster, the first advocate of learning, the first enemy of ignorance, the first to whisper in human ears the sacred word liberty, the creator of ambition, the author of modesty, of inquiry, of doubt, of investigation, of progress and of civilization.

Religion has not civilized man, man has civilized religion.
