It is commonly thought that the dispositional view of purposiveness is itself incompatible with the programmatic claims of neurophysiologists. In this paper, various versions of four arguments for this incompatibility are examined, and rejected as unsound. Central to the argument is a rough sketch of a "mechanistic" position which seems clearly compatible with a dispositional view of purposiveness.

This paper develops and draws the consequences of an etiological analysis of goal-directedness modeled on one that functions centrally in Charles Taylor's work on action. The author first presents, criticizes, and modifies Taylor's formulation, and then shows his modified formulation accounts easily for much of the fine-structure of teleological concepts and conceptualizations. Throughout, the author is at pains to show that teleological explanations are orthodox from an empiricist's point of view: they require nothing novel methodologically.

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.
