Well yes. Your freewill, my freewill... If determinism really breaks when intentional agents are involved, then I think we need to analyze whether that is plausible.
That is where this all started. I think I showed billions of exception to determinism and then the trolley went off the rails and I could not get it back on track by any means possible.
This goes far beyond moral responsability.
The only reason moral responsibility came up is because the context of the encyclopedia article was from that point of view which caused me even more confusion because your newly defined compatibilists believe free will is determined and yet we are morally accountable. In fact compatabalism as you define it may be the most self contradictory position I have ever heard of. It doubles back on it's self so many times I lose track. Do me a big favor and whatever we discuss lets keep compatabalism out of it. The position is so incoherent it is if I stare into it's eyes too long I will lose my sanity.
A defeater of determinism, by leaving open the future, has significant physical consequences, since determinism-breaking free will would be able to cause the motion of objects and bodies in a way that is not deducible, not even in principle, by prior physical conditions.
Will does not have a physical property. Will is a strange thing and I think it would be easier to explain what it is not. The result of will would not be a break with physical laws, once will is transformed into an action the action would be confined to natural law. IOW initial conditions cannot explain why I chose to throw a curve ball instead of fast ball. However once that decision was actualized it was bound by the laws of physics. Natural law can explain why the ball curved not why I decided the throw a curving ball. That is if I understand what you were trying to say.
If you think of causes having two aspect, mechanism and agency it is easier to see. Physics is a description not a prescription, will would be more of a prescription or agency and physics more of a mechanism.
So, you seem to claim that your decisions, or will, is such that no further explanation can be given for it. Is that equivalent to saying that your will is such that no further CAUSE can be given for it? If not, and only if not, what is the cause of your will?
I do not mean to say no further explanation exists, my prior statement claim the exact opposite, my claim is that no one or at least I am not able to adequately describe it. Now this is true in some ways for every one. I do not need to be able to explain how combustion works to believe it explains how we went to the moon, no one knows how gravity works yet everyone believes it cause masses to attract.
Let me cut this short so I can ask you something. I saw a documentary on relativity, specifically your curved space idea. To summarize Einstein predicted that if space was curved light would bend while passing large masses like the sun. To prove it is an interesting story but to cut it short he saw light bend around the sun during an eclipse. However would not the Newtonian idea of gravity attracting objects produce the exact same evidence? IOW whether I pushed the bar or pulled it in order to bend it the end result would be the same, so how do I find a bent bar and claim it is proof it was pushed not pulled?
BTW your entire post seems to be able to be summed up by saying if freewill exists it is meaningful. I agree but don't see anything to analyze. I believe free-will exists (and it is actually free) and I believe it's existence makes a coherent and consistent model of reality and validates our general human intuitions like moral responsibility. To deny it is to dismiss that thing that harmonizes the sum total of human experience and intuition.
