“There is something in natural affection which will lead it on to eternal love more easily than natural appetite could be led on. But there's also something in it which makes it easier to stop at the natural level and mistake it for the heavenly. Brass is mistaken for gold more easily than clay is. And if it finally refuses conversion its corruption will be worse than the corruption of what ye call the lower passions. It is a stronger angel, and therefor, when it falls, a fiercer devil.”

“And dying is more natural than living, because what could be more unnatural than that panicstricken thing leaping and falling like a last flame beneath the ribs?”

“It is no more natural and no less conventional to shout in anger or to kiss in love than to call a table 'a table'. Feelings and passional conduct are invented like words. Even those which like paternity seem to be part and parcel of the human make-up are in reality institutions. It is impossible to superimpose on man a lower layer of behavior which one chooses to call 'natural' followed by a manufactured cultural or spiritual world. Everything is both manufactured and natural in man as it were in the sense that there is not a word, not a form of behavior which does not owe something to purely biological being and which at the same time does not elude the simplicity of animal life and cause forms of vital behavior to deviate from their pre-ordained direction through a sort of leakage and through a genius for ambiguity which might serve to define man.”

“All the devils in hell and tempters on earth could do us no injury if there were no corruption in our own natures.”

“The power of evil was nothing more than a tangible thing, something that given the strength of will, could be broken as easily as glass.”

“Erotic acts are instinctive; they fulfill a role in nature. The idea is familiar, but it is one that contains a paradox: there is nothing more natural than sexual desire; there is nothing less natural than the forms in which it is made manifest and satisfied.”
