Since when was "physical" a synonym for "deterministic"
Name one non-deterministic macroscopic process that affects objects on the scale of neurons.
Any process critically dependent on its starting conditions = chaos.
Any microscopic event triggered by a device capable of measuring quantum levels events, eg a bomb hooked up to a geiger counter.
Typical stochastic devices, such as dice.
The brain doesn't do this, so how is this relevant to free will?
Dice are deterministic. Chaotic behavior != indeterminism.
I assume they are using the "physics is deterministic" assumption when they tell me our thought process is a physical process.
My OP above questions this and I speculate that there is randomness in base physics (quantum or somewhere else, maybe at macro level too when systems cross certain levels of complexity).
Some people seem to think that incompatibilist free will is definitionally the ability to transcend physics, although voluntarists don't usually define it that way. It may be a confusions arising from the fact that if physics is determimistic, an override would be needed to get incompatibilist FW.
