Your Brain, Your Mind, and Who You Are

You find yourself humming a tune. Or an old friend from the distant past pops into your head. These are some of the countless unbidden thoughts that come from the deep hidden parts of your brain. In fact, decisions you think you’re consciously making have already been made down in that secret place. How the brain works has ethical implications including: How free is free will? How guilty are the guilty? What makes us helpless in dealing with our problems? And, ultimately, it makes clear something we already know—that we can’t get through life without occasional “outside” help.
