But how can I possibly have the ability to assert if I do not have the freedom to assert?
Seriously? I could write a computer program that just asserts like you do.
An assertion must have a root cause, but in the physically determined secular world there can be no root cause, just endless chains of unavoidable reactions under the control of nature.
So the logic for my position is simply that any assertion I make of my own free will must be determined by something which is not under the unavoidable deterministic control of nature, but under the spiritually determined control of my conscious awareness...
So (here we go again) how does "conscious awareness" arrive at its decisions? Bearing in mind (as as been discussed at length before) that 'not deterministic'
means random and not random
means deterministic and hence all events (including conscious choices) must be the result of some combination of the two.
Also bearing in mind that the above is a logical statement that has nothing whatsoever to do with whether choices and consciousness are physical/material or not.
It's been some time, have you thought of an answer yet (other than "I don't know, it must be logic defying magic")?
