“Men can imagine their own deaths, they can see them coming, and the mere though of impending death acts like an aphrodisiac. A dog or rabbit doesn't behave like that. Take birds -- in a lean season they cut down on the eggs, or they won't mate at all. They put their energy into staying alive themselves until times get better. But human beings hope they can stick their souls into someone else, some new version of themselves, and live on forever. As a species were doomed by hope, then?You could call it hope.

“Jimmy, look at it realistically. You can't couple a minimum access to food with an expanding population indefinitely. Homo sapiens doesn't seem to be able to cut himself off at the supply end. He's one of the few species that doesn't limit reproduction in the face of dwindling resources.

“The idealist hopes. The romantic sees doom. The postmodernist sees doom and hopes.”
