Who said “The healthy man does not torture others -- generally it is the tortured who turn into…”?

“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.”

“Torment, for some men, is a need, an appetite, and an accomplishment.”

“I've already told you: the only way to a woman's heart is along the path of torment. I know none other as sure.”

“Man torturing man is a fiend beyond description. You turn a corner in the dark and there he is. You congeal into a bundle of inanimate fear. You become the very soul of anesthesia. But there is no escaping him. It is your turn now...”

“The universe appears to me like an immense, inexorable torture-garden. Passions, greed, hatred, and lies; law, social institutions, justice, love, glory, heroism, and religion: these are its monstrous flowers and its hideous instruments of eternal human suffering.”

“There is no coming to consciousness without pain.”

“Man needs difficulties; they are necessary for health.”

“Our blight is ideologies -- they are the long-expected Antichrist!”

“If one does not understand a person, one tends to regard him as a fool.”

“Everything that irritates us about others can lead us to an understanding of ourselves.”

“There can be no transforming of darkness into light and of apathy into movement without emotion.”
