More than half of our neighbors believe that the entire cosmos was created six thousand years ago. This is, incidentally, about a thousand years afte… - Sam Harris

Without free will, sinners and criminals would be nothing more than poorly calibrated clockwork,

A belief is a lever that, once pulled, moves almost everything in a person’s life. Are you a scientist? A liberal? A racist? These are merely species of belief in action. Your beliefs define your vision of the world; they dictate your behavior; they determine your emotional responses to other human beings. If you doubt this, consider how your experience would suddenly change if you came to believe one of the following propositions:

1. You have only two weeks to live.
2. You've just won the lottery prize of one hundred million dollars.
3. Aliens have implanted a receiver in your skull and are manipulating your thoughts.

These are mere words- until you believe them. once believed, they become part of the very apparatus of your mind, determining your desires, fears, expectations, and subsequent behavior.

There is a distinction between voluntary and involuntary actions, of course, but it does nothing to support the common idea of free will (nor does it depend upon it). A voluntary action is accompanied by the felt intention to carry it out, whereas an involuntary action isn’t. Needless to say, this difference is reflected at the level of the brain. And what a person consciously intends to do says a lot about him. It makes sense to treat a man who enjoys murdering children differently from one who accidentally hit and killed a child with his car — because the conscious intentions of the former give us a lot of information about how he is likely to behave in the future. But where intentions themselves come from, and what determines their character in every instance, remains perfectly mysterious in subjective terms. Our sense of free will results from a failure to appreciate this: We do not know what we intend to do until the intention itself arises. To understand this is to realize that we are not the authors of our thoughts and actions in the way that people generally suppose.
