I think the greatest work in social psychology from the 1950s and '60s is enormously important. I wish every high school kid could take a course in social psychology. I think we're making enormous strides in understanding the brain. These aren't yet giving us great insights, but I feel like we're on the verge of it. In five or ten years this basically searching the brain is really going to change things.

I think of myself as a social scientist. In order to get hired and to get promoted, we're forced to declare a disciplinary and sub-disciplinary specialty, so I am a psychologist and I am a social psychologist within that. But I think the exciting thing is to think about the social sciences in general and the nature of society. It's one of the hardest things to think about, because our brains aren't designed to think about these emergent entities. We're not good at it.

Sports is to war as pornography is to sex. We get to exercise some ancient, ancient drives.

To understand most important ideas in psychology, you need to understand how the mind is divided into parts that sometimes conflict. We assume that there is one person in each body, but in some ways we are each more like a committee whose members have been thrown together to do a job, but who often find themselves working at cross purposes.

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.

Love and work are to people what water and sunshine are to plants.

America is very much about individual happiness, the right to expression, self-determination. In America you do need to point to harm befalls victims before you can limit someone else's rights.
