Yet except when it is so elementary or fundamental as to be part of Nature, it is but a guide, and a guide that is only a child, so young, so capricious, that in every age its wayward hand has sought to pull Nature in a different direction.

Even only in order to guide we must first see and know.
We realise that never more than when we observe the distinction which conventional sex-morals so often makes between men and women.

Failing to find in women exactly the same kind of sexual emotions, as they find in themselves, men have concluded that there are none there at all.

So man has regarded himself as the sexual animal, and woman as either the passive object of his adoring love or the helpless victim of his degrading lust, in either case as a being who, unlike man, possessed an innocent "purity" by nature, without any need for the trouble of acquiring it.

Of woman as a real human being, with sexual needs and sexual responsibilities, morality has often known nothing.
