The physiologist Benjamin Libet famously demonstrated that activity in the
brain's motor regions can be detected some 300 milliseconds before a person
feels that he has decided to move. Another lab recently used fMRI data to
show that some conscious decisions can be predicted up to 10 seconds
before they enter awareness (long before the preparatory motor activity
detected by Libet). Clearly, findings of this kind are difficult to
reconcile with the sense that one is the conscious source of one's actions.
The question of free will is no mere curio of philosophy seminars. A belief
in free will underwrites both the religious notion of sin and our
enduring commitment to retributive justice. The Supreme Court has called
free will a universal and persistent foundation for our system of law.
Any scientific developments that threatened our notion of free will would
seem to put the ethics of punishing people for their bad behaviour in
question.In Free Will Harris debates these ideas and asks whether or not,
given what brain science is telling us, we actually have free will?
