The president is the high priest of what sociologist Robert Bellah calls the 'American civil religion.' The president must invoke the name of God (though not Jesus), glorify America's heroes and history,quote its sacred texts (the Declaration of Independence and the Constitution), and perform the transubstantiation of pluribus unum.

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

Understanding the simple fact that morality differs around the world, and even within societies, is the first step toward understanding your righteous mind.

In college, I was dead set on being a philosophy major, because I wanted to figure out the meaning of life. Four years later I realized philosophy had really nothing to say about the meaning of life, and psychology and literature are really where it's at.

If you grow up in a WEIRD society, you become so well educated in the ethic of autonomy that you can detect oppression and inequality even where the apparent victims see nothing wrong.

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.

But the most important lesson I have learned in my twenty years or research on morality is that nearly all people are morally motivated. Selfishness is a powerful force, particularly in the decisions of individuals, but whenever groups of people come together to make a sustained effort to change the world, you can bet that they are pursuing a vision of virtue, justice, or sacredness.
