Sacredness binds people together, and then blinds them to the arbitrariness of the practice.

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.

We scientists have way too much a tendency to simplify problems. I guess it actually comes to us naturally. Take the simplest unit, separate out all the confusing, external factors. Study it. Make sure you understand it. And in psychology that means the person studying the individual. But if you want to study our social nature, if you want to study processes that will lead to war and peace, you don't learn all that much by looking at the single individual. A lot of the important things are emergent facts about us, things that you can only see when you get a lot of us interacting.

We can tolerate great diversity in our aesthetic beliefs, but we can't tolerate much diversity in our moral beliefs.

Scandal is great entertainment because it allows people to feel contempt, a moral emotion that gives feelings of moral superiority while asking nothing in return. With contempt you don't need to right the wrong (as with anger) or flee the scene (as with fear or disgust). And the best of all, contempt is made to share. Stories about the moral failings of others are among the most common kinds of gossip, they are a stable of talk radio, and they offer a ready way for people to show that they share a common moral orientation.

The world doesn't usually affect us directly. It's what we do with it. It's the filters that we put on it. That's the foundation of certainly most pop-psychology, and of a lot of psychotherapy, cognitive therapy. So that, I think, is the greatest truth.

Conservatives tend to see the world more in terms of good-versus-evil and, for some of them, the nightmare is a disarmed citizenry that can be preyed upon by criminals. They know that having a gun in the house would increase the risk of an accident for a member of their family, but they're willing to take that risk.
