A pretty informative and short book.
Here are some text that I highlighted in the book:
The experimenters found two brain regions that contained information about which button subjects would press a full 7 to 10 seconds before the decision was consciously made. More recently, direct recordings from the cortex showed that the activity of merely 256 neurons was sufficient to predict with 80 percent accuracy a person’s decision to move 700 milliseconds before he became aware of it. These findings are difficult to reconcile with the sense that we are the conscious authors of our actions. One fact now seems indisputable: Some moments before you are aware of what you will do next—a time in which you subjectively appear to have complete freedom to behave however you please—your brain has already determined what you will do. You then become conscious of this “decision” and believe that you are in the process of making it.
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.
Speaking from personal experience, I think that losing the sense of free will has only improved my ethics—by increasing my feelings of compassion and forgiveness, and diminishing my sense of entitlement to the fruits of my own good luck.
