Thought is actively spontaneous thus making the brain's "I" attachment non-algorithmic. So it must be said that if we can predict and calculate a particle or neuron's position and velocity at the same time limitlessly, we would master our own fate. If thought A results in action a, then thought B results in b...etc. This is human causality, which is utterly predictable. Yet if it is possible to consciously change, we can. So this would obviously be free will at its finest.
