Happiness is not the shallow state of feeling pleased and chipper all the time. Happiness is the state of a human being that has achieved cross-level coherence within herself, and between herself and the people, challenges, and institutions around her. Happiness comes from between.

I believe that an evolutionary approach specifying the foundation of our moral sense can allow us to appreciate Hindu and Muslim cultures where women are veiled and seem to us to lead restricted lives.

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 Republicans need to take income inequality more seriously. Not because I favor equality of outcomes. I do not. I think the Right is correct to stress merit and earned rewards, not handouts and forced equality. But I think what Republicans are blind to is that power corrupts.

In real life, however, you don't react to what someone did; you react only to what you think she did, and the gap between action and perception is bridged by the art of impression management.

The final moment of success is often no more thrilling than taking off a heavy backpack at the end of a long hike. If you went on the hike only to feel that pleasure, you are a fool. Yet people sometimes do just this. They work hard at a task and expect some special euphoria at the end. But when they achieve success and find only moderate and short-lived pleasure, they ask is that all there is? They devalue their accomplishments as a striving after wind. We can call this the progress principle: Pleasure comes more from making progress toward goals than from achieving them.

People are wrong when they say that everything should be more diverse, even, say, rock bands. It's an error, an overgeneralization.
