Overview of Free Will

In the terminology of philosophy, Causal Determinism is the doctrine that every event is brought about necessarily and unavoidably by causes in the past.

If true, it means that a sufficently infomed intelligence cannot be wrong about the future. Some, compatibilists, believe the questions of determinism is unimportant because people can still have free will even if the future is fixed. They are wrong

Since compatibilism is false (equivalently, incompatibilism is true), determinism and free will cannot both exist. Evidence that determinism is wrong comes from Quantum Mechanics. Does that mean free will is true ?

Some say not, because QM implies randomness, and if you behave at random, you are no more free than if you were following a pre-programmed course. However, randomness is not and cannot be a empirical fact and the empirical falsehood of determinism does not impy randomness of a kind inimical to free will.

Indeed, it is possible costruct a naturalistic theory in which free will is implemented by indeterminism in a way which is not inimical to the level of rationality we actually have.
