It is nice to see someone else stepping in here. I am a bit exhausted!
Yes, I've seen this type of argument before. I think that
Monty Python did a skit on it involving King Arthur and his nemesis, the Black Knight.
Compatibilists fail to make a case for compatibility, yet they argue regardless.
That is indeed tiring. It feels much the same as arguing with theists.
Again;
Bruce Silverstein, B.A. Philosophy
''Compatibilism is a position that seeks to harmonize Determinism (or Causal Determinism) and Free Will, and posits that they can coexist— typically (i) by watering down the pure form of Free Will to include the illusion of choice that exists prior to the inexorable occurrence of determined activity that is not and cannot be known until after it occurs, or (ii) by watering down Causal Determinism to exclude human cognition from the inexorable path of causation forged through the universe long before human beings came into existence — or by watering down both concepts. Notably, Compatibilism simply stakes out a position respecting the relationship between Determinism and Free Will, and does not take a position as to whether Determinism is true or Free Will exists — or neither. Rather, Compatibilism simply posits that the two concepts can coexist (to the extent that either or both exist).
As explained below, based on my understanding of Determinism and Free Will, I believe that Compatiblism is not supported by sound logic, and results from an emotional resistance to accepting the absence of Free Will. Then, again, if Determinism is true, people who believe in Compatibilism are compelled to have that belief, and are incapable of having any other belief.
''As I understand it, Determinism posits that all activity in the universe is both (i) the effect of [all] antecedent activity, and (ii) the only activity that can occur given the antecedent activity. That is what is meant by saying that everything is “determined” — it is the inexorable consequence of activity that preceded it. If Determinism is true, everything that has ever occurred, is occurring, and will occur since the universe came into existence (however that might have occurred) can only occur exactly as it has occurred, is occurring, or will occur, and cannot possibly occur in any different manner. This mandated activity necessarily includes all human action, including all human cognition.
As I understand the notion of Free Will, it posits that a human being, when presented with more than one course of action, has the freedom or agency to choose between or among the alternatives, and that the state of affairs that exists in the universe immediately prior to the putative exercise of that freedom of choice does not eliminate all but one option and compel the selection of only one of the available options.
Based on the foregoing, if Determinism is true, human beings lack the ability to think in a manner that is not 100% caused by prior activity that is outside of their control, and thereby lack Free Will. By the same token, if human beings have Free-Will, they are capable of thinking in a manner that is not 100% caused by prior activity that is outside of their control, which rules out Determinism. Based on the foregoing, Determinism and Free Will are irreconcilably incompatible unless (i) Determinism is defined to exclude human cognition from the inexorable path of causation forged through the universe long before human beings came into existence, and/or (ii) Free Will is defined to be include the illusion of human cognition that is a part of the path of Determinism. As I see it, however, watering down either or both definitions does justice to neither concept, and is a cowardly approach to dealing forthrightly with the full implications of either concept being true.''
