The point being that it is the unchosen state and condition of the brain in any given instance of decision making that determines the thoughts and actions that are taken in that instance.
And we have shown again and again how: the brain does have the power to choose its own future state. I spent some good amount of time even describing that whole process and even demonstrating for you how you can make a system for which you can
trivially observe the process of it choosing its own future operational text from a list of operational text based on its own current operational text.
This directly disproves your claim, and in fact validates through the trivial clear observation of the principle.
As pointed out by Copernicus in the other thread, this means the paradox in which we clearly observe the outcome, in the midst of your belief that this outcome must be impossible, means that some aspect of your use of language MUST be in error.
We have heavily discussed what that error is and why: it's a modal fallacy, caused by your belief in "the set of all sets", which you call "necessitation", identified clearly by some quality of "omniscience" and creation which you use to improperly justify this injection of nonsense.
That is not actually responsive to DBT. Well, it is not actually responsive to my interpretation/understanding of what DBT is trying to say. I am under the impression that DBT sees this discussion as regarding whether a something referred to as
free will is compatible with an other something referred to as
determinism with the term
compatibilism in this discussion being understood as the holding that determinism is compatible with free will (and/or vice versa).
DBT and the self-described compatibilists both refer to
determinism; so, the first question is whether DBT and the self-described compatibilists understand
determinism identically.
DBT appears to regard determinism in strictly reductive physicalist terms with that physicalism maintaining that there is no occasion in which there is human control over what occurs physically, and, since all that occurs is physical, there is no frank human control. DBT does not deny that there are humans and human acts; DBT does not deny that humans feel/think they have some control; he simply asserts that there is physical activity occurring entirely in accord with a regularity sufficient for there to be the sufficient descriptions provided by or referred to as
physics.
DBT has a tendency to express his thinking in terms of physics as controlling, and that is how his expression comes to be in terms of
must rather than
will; however, as the previous paragraph makes apparent, the reductive physicalist account to which DBT seems to hold has no need of there being - has no need of reference to - any sort of control whatsoever: not human and not even physical.
This means that for DBT,
determinism is the belief that the physical is sufficiently consistently regular such that all which occurs is fixed, settled, determined to be as it occurs whether it has occurred or will occur, whether it has already become or been actual or whether it is yet to be actual.
I think that what DBT wants to know is whether the self-described compatibilists in this discussion have the same understanding about determinism as that presented in the previous paragraph.
If yes, there then follows the matter of free will, but, if the compatibilists do not have the same understanding about determinism which DBT seems to have, then the matter of free will and whether it is compatible with determinism is not really at issue. The issue would simply be: what is determinism?
It does no good to say "we have shown again and again". If DBT is (thought to be) intentionally recalcitrant, then stop showing and stop saying he has been shown. If what has supposedly been "shown again and again" makes no sense to DBT, then a new and different manner of expression can be tried in place of that manner of expression which has been used "again and again".
For reasons which should be obvious, it does no good to describe determinism as deterministic or in terms of deterministic systems. Maybe DBT cannot free himself from thinking in terms of control, and maybe DBT or someone else would want to modify the description of determinism as the belief that there is only physical activity occurring entirely in accord with a regularity sufficient for there to be the sufficient descriptions provided by or referred to as
physics with the physical being sufficiently consistently regular such that all which occurs is fixed, settled, determined to be as it occurs whether it has occurred or will occur, whether it has already become or been actual or whether it is yet to be actual.
Then again, maybe I have misunderstood DBT's contention.
