I review a widely accepted argument to the conclusion that the contents of our beliefs, desires and other mental states cannot be causally efficacious in a classical computational model of the mind. I reply that this argument rests essentially on an assumption about the nature of neural structure that we have no good scientific reason to accept. I conclude that computationalism is compatible with wide semantic causal efficacy, and suggest how the computational model might be modified to accommodate this possibility.

I separate two intrinsic/extrinsic distinctions that are often conflated: one between properties (the intrinsic/extrinsic, or I/E, distinction) and one between the ways in which properties are had by individuals (the intrinsically/extrinsically, or I-ly/E-ly, distinction). I propose an analysis of the I-ly/E-ly distinction and its relation to the I/E distinction that explains, inter alia, the puzzle of cross-classification: how it can be, for example, that the property of being square can be classified as an intrinsic property and yet individuals can be (...) square intrinsically or else extrinsically.

Fred Dretske?s (1988) account of the causal role of intentional mental states was widely criticized for missing the target: he explained why a type of intentional state causes the type of bodily motion it does rather than some other type, when what we wanted was an account of how the intentional properties of these states play a causal role in each singular causal relation with a token bodily motion. I argue that the non-reductive metaphysics that Dretske defends for his account (...) of behavior can be extended to the case of intentional states, and that this extension provides a way to show how intentional properties can play the causal role that we wanted explained.
