Speak of a wolf and you see his tail!

He who desires to see the living God face-to-face should not seek him in the empty, firmament of his mind, but in human love.

A man who lies to himself, and believes his own lies, becomes unable to recognize truth, either in himself or in anyone else, and he ends up losing respect for himself and for others.

You cannot imagine what sorrow and anger seize one's whole soul when a great idea, which one has long and piously revered, is picked up by some bunglers and dragged into the street, to more fools like themselves, and one suddenly meets it in the flea market, unrecognizable, dirty, askew, absurdly presented, without proportion, without harmony, a toy for stupid children.
