It’s tempting to imagine that self-knowledge is easy to come by. All you have to do is introspect. The idea is that the mind is kind of like a clear glass fishbowl. If you want to know what’s going on, all you’ve got to do is take a look. But there are problems with this idea.

Most people seem think that knowing themselves is a good idea, or at least say that that’s what they think. “Know thyself,” is uttered reverently—as though it’s self-evidently a wonderful goal.
