The distinction made between compatibilism and limited potential free will strikes me as too vague to be one with a difference. By that I mean that compatibilism can be defined in such a way as to include whatever it is that the PLFW proponents are attempting to say. It is just the position that free will is fully definable within a deterministic system, because having choices to make and then selecting one of them in ignorance of the full consequences is a process determined by limited knowledge of the future. In hindsight, other choices could always have been selected, once events reveal those consequences, but the scope of determinism in these debates always includes hindsight. So the act of making a choice is always viewed from that perspective. If one believes in libertarian free will, then one only does so by forgetting the omniscience granted to those who have the advantage of viewing the future as if it were hindsight. The illusion of free will in that sense simply considers that hindsight would have been different if a different choice had been made with the advantage of foresight, an advantage that one never has when deciding to take an action.
You define Compatibilism too broadly. Compatibilism is one of the most misunderstood philosophies concerning Free Will.
"Soft determinism (or
compatibilism) is the position or view that causal determinism is true, but we still act as free, morally responsible agents when, in the absence of external constraints, our actions are caused by our desires.
Compatibilism does not maintain that humans are free. Compatibilism does not hold that humans have free will.
Compatibilism holds that:
1) the thesis of determinism is true, and that accordingly all human behavior, voluntary or involuntary, like the behavior of all other things, arises from antecedent conditions, given which no other behavior is possible: all human behavior is caused and determined
2)voluntary behavior is nonetheless free to the extent that it is not externally constrained or impeded
3) the causes of voluntary behavior are certain states, events, or conditions within the agent: acts of will or volitions, choices, decisions, desires etc...
Compatibilism is NOT a position that combines the libertarian and determinist positions.
Compatibilism is NOT a compromise of the two other positions.
Compatibilism is NOT a position that holds that humans are "a little bit" free.
Compatibilism is NOT a position that holds that humans have "limited free will".
Compatibilism is NOT a position that holds that humans have some free will.
Compatibilism is determinism with a slight modification for the sake of appearances and for our language use. It is a position taken because of the perceived need to have some idea of accountability or responsibility for human behavior."
It is late, but tomorrow I will go into more detail, but the concept of Potential Limited Free Will is not remotely a form of Compatibilism.
Though I do not equate Compatibilism with 'Soft Determinism.'
