Unnatural distinctions are naturally slippery

Don't put yourself down when you find you have mistaken lust for love. You may have had both for a moment because evolution has short circuited the two together.

Lust barely suffices for the increase of our numbers and by itself increases our strife by the long tail of its unfunded consequences. Love suffices for the increase of our civilization. How lucky are they that hold the mixture, ever new, between them.
