The anti-Totalitarian logic admittedly just goes into overdrive, but, how can you trust a Determinist? When the question goes unanswered, why ascribe to such a position? It seems like a trustworthy person could only have come to such conclusions through some sort of pessimism unless they invoke the divine. The qualified arguments are the only ones that are really occuring. Everything else is just speculation. A person would, perhaps, be best off without any preconceptions whatsoever, but, how is that possible? No person's experience of the world is devoid of the concept of freedom. I do admit that I do assume too much in regards to the Determinist standpoint, but, I do think that a person does have a reason to skeptical of it.

Delimiting potentialities does not disqualify free potential itself.

I do think what can be known of free will at this given point in time is that it is self-evident. You do experience the world as if you do have "free will". Without any evidence to the contrary, I see no reason not to act accordingly. The concept concerns a basic aspect of Being. It is relevant to a lot of discussions and not a mere particularity.

Like I said, I was being a bit too harsh. I just think that the consensus amongst Mind-Body philosophers is a bit off. This is probably just resultant of a lack of introspection.
