"It is the duty of the human understanding to understand that there are things which it cannot understand, and what those things are. Human understanding has vulgarly occupied itself with nothing but understanding, but if it would only take the trouble to understand itself at the same time it would simply have to posit the paradox."

"There is only one thing that arouses animals more than pleasure, and that is pain. Under torture you are as if under the dominion of those grasses that produce visions. Everything you have heard told, everything you have read returns to your mind, as if you were being transported, not toward heaven, but toward hell. Under torture you say not only what the inquisitor wants, but also what you imagine might please him, because a bond (this, truly, diabolical) is established between you and him."
