Severian's Wisdom, Part I: Not By Sex Alone

"Women believe - or at least often pretend to believe - that all our tenderness for them springs from desire; that we love them when we have not for a time enjoyed them, and dismiss them when we are sated, or to express it more precisely, exhausted. There is no truth in this idea, though it may be made to appear true. When we are rigid with desire, we are apt to pretend a great tenderness in the hope of satisfying that desire; but at no other time are we in fact so liable to treat women brutally, and so unlikely to feel any deep emotion but one."

-from Gene Wolfe's epic New Sun series, book two, "The Claw of the Conciliator"
