Lightly seared on the reality grill.
Consider the definition of determinism; this one from the Encyclopedia Britannica:
Determinism,
in philosophy, theory that all events, including moral choices, are completely determined by previously existing causes.
If one believes that all events, including moral choices, are completely determined by previously existing, how does free will fit into the equation?
The point is that something has to do the choosing and it has to make one choice rather than another for some reasons. Those reasons must be to do with the actual person (personality, experience, and so on), the person's current state of mind, and the circumstances of the choice. All those conditions are, in turn, due to reasons.
If all the reasons for a choice do not fully determine the outcome (determinism), then some aspect of the choice must not be due to the reasons that led to it, that is, for no reason - which means random. I don't see how randomness helps with freedom (although some have argued it does).
We are the people our nature, nurture, and experience has made us, and it makes no sense to be free from being oneself.
However, my question would be, if that's true, then what is behind the reason one chose A over B?
Indeed.
