That is why some people have brains that lie to them less then others, while others have brains that lie more. You will find different degrees of bias and delusion in the people you encounter.
What if atoms are not defined by deterministic rules? What if it's defined by probabilistic rules? Then are our brains bounded by the same probabilistic rules?
It seems that given that all brains are made of the same stuff as the universe, the question of free will is more of a physics question. What is the universe made of? And does this fundamental unit allow for free will?
