Free Will

You could say that free will is an illusion anyway. If there really is a
complete theory of physics that governs everything, it presumably also
determines your actions. But it does so in a way that is impossible to calculate
for an organism that is as complicated as a human being, and it involves a
certain randomness due to quantum mechanical effects. So one way to look at it
is that we say humans have free will because we can’t predict what he will do
because it will be part of recorded history.
