It seems to be the special peculiarity of human beings that they reflect: they think about thinking and know that they know. This, like other feedback systems, may lead to vicious circles and confusions if improperly managed, but self-awareness makes human experience resonant. It imparts that simultaneous "echo" to all that we think and feel as the box of a violin reverberates with the sound of the strings. It gives depth and volume to what would otherwise be shallow and flat.

Alan WattsA person who thinks all the time has nothing to think about except thoughts. So he loses touch with Reality, and lives in a world of illusion.
Alan WattsYou find out that the universe is a system that creeps up on itself and says 'Boo' and then laughs at itself for jumping.
