“What art should be about,' they will say, 'is revealing exquisite and resonant truths about the human condition.' Well, to be honest - no, it shouldn’t. I mean, it can occasionally, if it wants to; but really, how many penetrating insights to human nature do you need in one lifetime? Two? Three? Once you’ve realised that no one else has a clue what they’re doing, either, and that love can be totally pointless, any further insights into human nature just start getting depressing really.”

“But as the years went on, I realised that what I really want to be, all told, is a human. Just a productive, honest, courteously treated human.”

“The only thing that one really knows about human nature is that it changes. Change is the one quality we can predicate of it.”

“The task of evolutionary psychology is not to weigh in on human nature, a task better left to others. It is to add the satisfying kind of insight that only science can provide: to connect what we know about human nature with the rest of our knowledge of how the world works, and to explain the largest number of facts with the smallest number of assumptions.”

“I thought that it was strange to assume that it was abnormal for anyone to be forever asking questions about the nature of the universe, about what the human condition really was, my condition, what I was doing here, if there was really something to do. It seemed to me, on the contrary, that it was abnormal for people NOT to think about it, for them to allow themselves to live, as it were, unconsciously. Perhaps it's because everyone, all the others, are convinced in some unformulated, irrational way that one day everything will be made clear. Perhaps there will be a morning of grace for humanity. Perhaps there will be a morning of grace for me.”

“What of men? I can't think of anything more banal. I have no doubt — no doubt whatsoever — that once it has obtained the means to do so, the species will wipe itself off the face of the earth. There is no mystery to it; it is our nature. Oh, one might delve into the particulars, but really, what can we say about the species that invented murder? What can we say?”
