I took this Modus Tollens because it more-or-less holds the entire concept of 'sensations', like:1) If our decisions are physically derived (A), then "free will" is an illusion. (B)
2) Free will isn't an illusion, but really does exist. (~B)
3) Therefore we aren't entirely physically derived. (~A)
I can agree with that logical reasoning, but the indistintness/lack-of-clarity to me is whether the immaterial sensations are basically material sensations in itself.1) If our decisions are physically derived (A), then "immaterial sensations" are an illusion. (B)
2) Immaterial sensations aren't illusions, but really do exist. (~B)
3) Therefore we aren't entirely physically derived. (~A)
Consider:
1) If a material universe is all there is, 'immaterial sensations' cannot exist.
2) We do however experience 'immaterial sensations'.
3) Therefore immaterial sensations are in fact material sensations.
