@Fil Albuquerque,
Nice to be around someone with an operable intellect Fil!
When I discuss 'predeterminism' I am simply obliging the eternal construct of everything. 'Probabilisticism' is not an avenue that can be defined as conclusive.
Every event is governed by its cause. There is no 'probably' in the equation.
So, on a physical-level, all is determined.
And I don't believe that thoughts are somehow 'non-physical'
