The objective probability of every physical event is fixed by prior physical events and laws alone. (This thesis is sometimes expressed in terms of explanation: In tracing the causal history of any physical event, one need not advert to any non-physical events or laws. To the extent that there is any explanation available for a physical event, there is a complete explanation available couched entirely in physical vocabulary. We prefer the probability formulation, as it should be acceptable to any physicalist, (...) though some reject the explanation formulation.) (3) Causal Exclusion. (shrink)

One familiar affirmative answer to this question holds that these facts suffice to entail that Descartes' picture of the human mind must be mistaken. On Descartes' view, our mind or soul (the only essential part of ourselves) has no spatial location. Yet it directly interacts with but one physical object, the brain of that body with which it is, 'as it were, intermingled,' so as to 'form one unit.' The radical disparity posited between a nonspatial mind, whose intentional and conscious (...) properties are had by no physical object, and a spatial body, all of whose properties are had by no mind, has prompted some to conclude that, pace Descartes, causal interaction between the two is impossible. Jaegwon Kim has recently given a new twist to this old line of thought.(1) In the present essay, I will use Kim's argument as a springboard for motivating my own favored picture of the metaphysics of mind and body and then discussing how an often vilified account of freedom of the will may be realized within it.

The following framework of theses, roughly hewn, shapes contemporary discussion of the problem of mental causation: (1) Non-Identity of the Mental and the Physical Mental properties and states cannot be identified with specific physical properties and states. (2) Causal Closure (Completeness) of the Physical The objective probability of every physical event is fixed by prior physical events and laws alone. (This thesis is sometimes expressed in terms of explanation: In tracing the causal history of any physical event, one need not (...) advert to any non-physical events or laws. To the extent that there is any explanation available for a physical event, there is a complete explanation available couched entirely in physical vocabulary. We prefer the probability formulation, as it should be acceptable to any physicalist, though some reject the explanation formulation.) (3) Causal Exclusion There is at most one complete and wholly independent explanation for any given event or sequence of events. (shrink)

It’s been agreed for decades that not only does Determinism pose a big problem for our choosing from available alternatives, but its denial seems to pose a bit of a problem, too. It’s argued here that only Determinism, and not its denial, means no real choice for us.But, what explains the appeal of the thought that, where things aren’t fully determined, to that extent they’re just a matter of chance? It's the dominance of metaphysical suppositions that, together, comprise Scientiphicalism: Wholly (...) composed of such mindless physical parts as electrons, you are a being whose powers are all physical powers, physically deriving from the powers of your parts and their physical arrangements. Scientiphicalisrn conflicts with your having real choice.Some fairly conservative alternatives to Scientiphicalism may allow for choice. Two are briefly discussed: On the further-fetched, you are a Cartesian mental being, a nonphysical being in powerful interaction with physical things. On the more conservative approach, you are wholly composed of physical parts, but some of your powers are radically emergent, including your power to choose.Finally, it’s argued that, if you choose, you must be, to some extent, exempt from natural laws.
