I'm reading Conciousness Explained, by Daniel Dennet right now. It's pretty interesting and it deals with this topic of free will. This book makes my brain hurt, but it's cool how many experiments have been performed on how the brain works and the questions these raise. I, too, think that free will is an illusion of the brain, just as after you stop spinning you have the illusion that the room is still spinning even though you are stationary, or the illusion that two lights that blink in succession actually look like one light moving from one spot to the other, and can even change color in between in a sort of precognitive way. Really interesting stuff!
