The idea of God is the sole wrong for which I cannot forgive mankind.

Chimerical and empty being, your name alone has caused more blood to flow on the face of the earth than any political war ever will. Return to the nothingness from which the mad hope and ridiculous fright of men dared call you forth to their misfortune. You only appeared as a torment for the human race. What crimes would have been spared the world, if they had choked the first imbecile who thought of speaking of you.

Is it not of the imagination that the sharpest pleasures arise?

Any punishment that does not correct, that can merely rouse rebellion in whoever has to endure it, is a piece of gratuitous infamy which makes those who impose it more guilty in the eyes of humanity, good sense and reason, nay a hundred times more guilty than the victim on whom the punishment is inflicted.

Certain souls may seem harsh to others, but it is just a way, beknownst only to them, of caring and feeling more deeply.

The mirror sees the man as beautiful, the mirror loves the man; another mirror sees the man as frightful and hates him; and it is always the same being who produces the impressions.

Cruelty, very far from being a vice, is the first sentiment Nature injects in us all. The infant breaks his toy, bites his nurse's breast, strangles his canary long before he is able to reason; cruelty is stamped in animals, in whom, as I think I have said, Nature's laws are more emphatically to be read than in ourselves; cruelty exists amongst savages, so much nearer to Nature than civilized men are; absurd then to maintain cruelty is a consequence of depravity. . . . Cruelty is simply the energy in a man civilization has not yet altogether corrupted: therefore it is a virtue, not a vice.
