Marquis de Sade — "Crime is the soul of mankind."

"Sex should be a perfect balance of pain and pleasure. Without that symmetry, sex becomes a routine rather than an indulgence."

"I have always been convinced that the universe is a place of perpetual motion, and that this motion is always tending towards destruction."

"I prefer the madness of passion to the wisdom of indifference."

"And if I were a naughty little boy, the idea is to spank me into good behavior?"
