Happiness requires changing yourself and changing your world. It requires pursuing your own goals and fitting in with others. Different people at different times in their lives will benefit from drawing more heavily on one approach or the other.

Societies that exclude the exoskeleton of religion should reflect carefully to what will happen to them over several generations. We don’t really know, because the first atheistic societies have only emerged in Europe in the last few decades. They are the least efficient societies ever known at turning resources (of which they have a lot) into offspring (of which they have few).

I think that we Americans, in particular, tend to think too directly about problems. If there's a problem we want to basically go in with a screwdriver or else drop bombs on it. A better way to solve problems is to think indirectly and try to change the environment. So I think you can gain much better self-control not so much by working on yourself as by looking at the situations you're in and the people you hang around, and changing your environment.

Religion and science, for example, are often though to be opponents, but as I have shown, the insights of ancient religions and of modern science are both needed to reach a full understanding of human nature and the conditions of human satisfaction. The ancients may have known little about biology, chemistry, physics, but many were good psychologists.

Trying to run Congress without human relationships is like trying to run a car without motor oil. Should we be surprised when the whole thing freezes up?

I think sociologists are among the best at thinking about emergence, of thinking about the ways that the society is more than the sum of the individuals. And I've found that much of the wisest writing on human social nature comes from sociology and anthropology, not from my own field of social psychology.

I think that we are passionate creatures who really live our fullest life when we are deeply engaged, when we feel successes, and exult in them, when we feel losses and tragedies and are hurt by them. So I came to the conclusion that Eastern ideas of withdrawal may not be right for modern Westerners. If you read the ancient texts, they're pretty severe. I mean, they really are not the sort of thing that you would think compatible with really throwing yourself into life and being a part of it.
