The primary and most beautiful of Nature's qualities is motion, which agitates her at all times, but this motion is simply a perpetual consequence of crimes, she conserves it by means of crimes only.
Marquis de SadeHumane sentiments are baseless, mad, and improper; they are incredibly feeble; never do they withstand the gainsaying passions, never do they resist bare necessity.
Marquis de SadeNever lose sight of the fact that all human felicity lies in man's imagination, and that he cannot think to attain it unless he heeds all his caprices. The most fortunate of persons is he who has the most means to satisfy his vagaries.
Marquis de SadeCruelty, 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.
