Since the internal organization and workings of a human agent would be part of its identity, I've never quite understood how such can be contended, to begin with, to forfeit the agent being the source of its own intentions and decisions. A biological body is not anarchy -- its very form and functioning are biased constraints which make it distinct from noise and random patterns (the latter being analogous to complete vulgar liberty or lack of governance). Thus "free volition" for an intelligent organism [in response to _x_ situation or whatever] should be expected to be limited to the options available within the nature of its identity or what falls out of its specific character (what makes a body-type what it is, what makes a human what it is, what makes a particular acquired / developed personality what it is). To literally be totally free in terms of purpose, choice, and power would mean either being the author of a dream / virtual reality (god) or to be without organization. The latter is self-conflicting since it means eliminating the very sources for generating purpose, choice, and guided / resolute action. Ultimately, the debates about "free will" continue no matter what because of the maintained ambiguity surrounding what FW means. There's no consensus authority for satisfying all party goers as to what its account / significance can and cannot encompass in settled fashion. "Which suit, dress, or costume should I wear to the event tonight?" .... "All of them!"
