 : These questions are somewhat linked, but I agree with the reverter that the problem of free will is more cleanly presented without discussing the mind-body problem. In the added section, the proposition ""This dualism allows humans free will, because associated brain activity only is correlated with human action, and is not its cause"" is stated in Wikipedia's voice, but this is just one POV. For example, Simon Blackburn argues (very convincingly) in Think that the dilemma of determinism also applies to non-physical cuasation, so I'm fairly certain many philosophers would disagree that monism/dualism is at all relevant to the free will debate.
