It's a basic fact about being human that sometimes the self seems to just melt away.

In accounts of men in battle, there is an incredible adrenaline rush from group-versus-group conflict. The fervor and passion of partisans is clearly rewarding; and if it's rewarding, it involves dopamine; and if it involves dopamine, then it is potentially addictive.

I think the greatest truths, the ones that you find in every culture that has any sort of history of reflection of writing, the greatest truth is that there's nothing good or bad, but thinking makes it so. That's the way Shakespeare put it. But you get basically the same idea from Buddha, from the Bhagavad Gita in India, and from the Stoics in ancient Greece and Rome.

I think moral philosophy is speculation on how we ought to live together done by people who have very little clue how people work. So I think most moral philosophy is disconnected from the species that we happen to be. In fact, they like it that way. Many moral philosophers insist that morality grows out of our rationality, that it applies to any rational being anywhere in the universe, and that it is not based on contingent or coincidental facts about our evolution.

While the political right may moralize sex, the political left is doing it with food. Food is becoming extremely moralized nowadays, and a lot of it is ideas about purity, about what you're willing to touch, or put into your body.

Almost everything we do is automatic, yet we're not aware of that. We feel like there's a circle of light. We're like the drunk who lost his keys and is looking under the streetlight, and the cop says, "Where'd you lose your keys?" You say, "Back in the alley, but the light's so much better over here." The divided self refers to the fact that we are basically animals with animal brains. These animal brains run our lives. They're very good at it.

Congress is full of good, decent, smart people who have devoted their lives to public service.
