This provocative book refurbishes the traditional account of freedom of will as reasons-guided "agent" causation, situating its account within a general metaphysics. O'Connor's discussion of the general concept of causation and of ontological reductionism v. emergence will specially interest metaphysicians and philosophers of mind.

This is the text of The Lindley Lecture for 1964, given by Roderick M. Chisholm (1916-1999), an American philosopher.

What is a self? I will try to answer this question by developing an analogy with something much simpler, something which is nowhere near as puzzling as a self, but has some properties in common with selves. What I have in mind is the center of gravity of an object. This is a well-behaved concept in Newtonian physics. But a center of gravity is not an atom or a subatomic particle or any other physical item in the world. It has (...) no mass; it has no color; it has no physical properties at all, except for spatio-temporal location. It is a fine example of what Hans Reichenbach would call an abstractum. It is a purely abstract object. It is, if you like , a theorist's fiction. It is not one of the real things in the universe in addition to the atoms. But it is a fiction that has nicely defined, well delineated and well behaved role within physics. (shrink)

Norman Malcolm's recent argument against the conceivability of mechanism rests on the claim that purposive explanations of behavior – that is, explanations of behavior in terms of desires or intentions – are incompatible with neurophysiological explanations of behavior. I admit that intentions or desires can be causes of behavior only if they are necessary for behavior, and, generally, that events can be causes only if they are necessary for their effects (except in cases of over-determination). What I wish to deny (...) is the contention that if neurophysiological states are sufficient for behavior, then desires or intentions are not necessary for behavior. This latter contention seems to me the crux of Malcolm's argument for the incompatibility of mechanism and purpose; if this contention can be shown to be un acceptable, Malcolm's conclusion that mechanism and purpose are incompatible will remain without support.
