Humane 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 SadeIf the objects who serve us feel ecstacy, they are much more often concerned with themselves than with us, and our own enjoyment is consequently impaired. The idea of seeing another person experience the same pleasure reduces one to a kind of equality which spoils the unutterable charms that come from despotism.
Marquis de Sade
