To a very close approximation, a planet interacts only with the Sun. A two body system is entirely predictable.I have yet to read an articulation of what Free Will means in a universe that is entirely deterministic in the sense that human cognition is as controlled by antecedent forces as is the orbit of celestial objects.
A human is a hugely complex system with many internal interactions. Predictability breaks down when you have three or more bodies in your system.
A complex system can exhibit a "will of its own", doing things that an observer could never have anticipated. The (pointless but interminable) argument seems to be whether "will of its own" can ever be a factual claim about the complex system, or is always just a metaphor for a lack of knowledge on the part of the observer.
The combatibilist position is that it can be both. The incompatibilist position seems to be 'but God is all knowing, so from God's perspective, nothing has a "will of its own", God can always anticipate its next move'.
As an atheist, I am massively unconvinced by the practice of replacing God with a hypothetical philosophical God-zombie who can view the universe from an omnicognisant external perspective, and/or calculate the motions and interactions of every quantum of mass/energy faster than those interactions can occur.
Free will means that the complex system I call I, contains within it (and indeed, simply is) the only possible system that can predict its own future state; And it can only do so by stepping forward to that future.
I am completely unpredictable, and I am bounded by my skin, outside of which is a far more predictable universe, studded with other self-contained instances of unpredictability (some of whom I consider my friends). The short term decision making process is, to a very close approximation, based entirely on what happens within me; I have "a will of my own". Not even I can predict with perfect confidence what I will do next.
In the absence of a God, free will is entirely compatible with the physically deterministic nature of the universe.
The objections of the incompatibilists are religious in nature, even when they strip down their God to a mere p-zombie who does nothing but know the future.
If I agreed with your explanation of Determinism as used in Incompatibilism, I may well agree with much of the balance of your post. I disagree, however, that you have described Determinism -- at least as I understand it.
Predictability (even theoretically) is not an aspect of Determinism. Indeed, perfect predictability is as impossible in Determinism as it is in Indeterminism.
Nor is Determinism correlate with an omniscient God. That is an argument some folks have developed to explain a religious equivalency to Determinism that misunderstands and distorts Derterminism. Thus, I reject the following statement and suspect that there is no person who properly understands Determinism who would agree with the statement:
The incompatibilist position seems to be 'but God is all knowing, so from God's perspective, nothing has a "will of its own", God can always anticipate its next move'.
You net state:
As an atheist, I am massively unconvinced by the practice of replacing God with a hypothetical philosophical God-zombie who can view the universe from an omnicognisant external perspective, and/or calculate the motions and interactions of every quantum of mass/energy faster than those interactions can occur.
I, too, am an atheist, and I also would be "unconvinced by the practice of replacing God with a hypothetical philosophical God-zombie who can view the universe from an omnicognisant external perspective, and/or calculate the motions and interactions of every quantum of mass/energy faster than those interactions can." There was a time in the history of the Determinism debate that LaPlace posited such a God-zombie-like entity, which he called a "demon," but LaPlace's predictability hypothesis is not a part of mainstream or even classical Determinism except for a period of time in which LaPlace's demon was in vogue. I would be pleased to explain further why Determinism does not posit predictability, much less perfect or certain predictability, and that acceptance of the Determinism paradigm actually precludes such predictability -- even by LaPlace's foolish demon.
I similarly reject the following statement:
In the absence of a God, free will is entirely compatible with the physically deterministic nature of the universe.
Specifically, I reject that the predicate "n the absence of God" has anything to do with the issue. Indeed, as bet I understand the debate, the theoretical / hypothetical existence of God is not incompatible with the existence of Free Will. It is not a non-existent God that makes Determinism incompatible with Free Will. Rather, it is the definition of Determinism -- which, again, has nothing to do with predictability (even theoretically).
Plainly, I also reject the final statement:
The objections of the incompatibilists are religious in nature, even when they strip down their God to a mere p-zombie who does nothing but know the future.
Again, there not only is no omniscient God in Determinism, there is no p-zombie, there is no demon, and there is no predictability.
What there is in Determinism, if Determinism were true (and I am not advocating that it is), is simply the fact that all activity, including human cognition, is the inexorable and fixed effect of antecedent causes. Of course, the universe is an incredibly complex system, comprised or near-infinite smaller complex systems, which include human beings. Nobody is suggesting otherwise. Indeed, it is that incredible complexity that precludes predictability -- especially from within the system, which is the point of Godel's Incompleteness Theorem, among other things.
So, I return to my original statement that began the post to which I am replying -- namely:
I have yet to read an articulation of what Free Will means in a universe that is entirely deterministic in the sense that human cognition is as controlled by antecedent forces as is the orbit of celestial objects.
While criticizing the notion that "human cognition is as controlled by antecedent forces as is the orbit of celestial objects," the post to which I am replying does not offer an explanation of what Free Will would mean in a hypothetical universe in which it is the case that "human cognition is as controlled by antecedent forces as is the orbit of celestial objects." Yet another post that avoids the question by criticizing and rejecting Determinism without offering any defense of Free Will if Determinism is accepted (arguendo) as true.
Post-script: I have no idea where the italics came from. I have tried multiple times to get rid of them, but the website insists upon keeping them -- as if it were determined to be that way.
