    If physics cannot predict even in theory when the neurons will fire
    then *by definition* the neurons behave contrary to physics.

If the neurons fire based on the participation of a personal identity in response to events in a person's life, then how could physics predict them without predicting a person's entire life?


Good point! Physical systems are completely blind to their history, or so we are told...
