Understanding our own minds

Freud was wrong about most things, but one thing he was dead on about was that we have at best limited access to our own minds. Here is an excellent quote from Daniel Dennet's Freedom Evolves:

For Descartes, the mind was perfectly transparent to itself, with nothing happening out of view, and it has taken more than a century of psychological theorizing and experimentation to erode this ideal of perfect introspectability, which we can now see gets the situation almost backward. Consciousness of the springs of action is the exception, not the rule, and it requires some rather remarkable circumstances to have evolved at all.
