Causal theories of mental content attempt to explain how thoughts can be about things. They attempt to explain how one can think about, for example, dogs. These theories begin with the idea that there are mental representations and that thoughts are meaningful in virtue of a causal connection between a mental representation and some part of the world that is represented. In other words, the point of departure for these theories is that thoughts of dogs are about dogs because dogs (...) cause the mental representations of dogs. (shrink)

But it’s not the mere fact that the RA theorist needs an account of ‘ruling out’ and ‘relevance’ that has tended to lead people to regard the RA approach with suspicion. In itself, this simply means that the RA theorist has some further work to do; and what theorist doesn’t? No; the principal source of scepticism regarding the ability of the RA theorist to come up with a complete and satisfactory account of knowing stems, rather, from an unhappiness with the (...) specific elaborations of the core RA claim that various theorists have offered; for these elaborations have typically involved some rather controversial claims and/or assumptions, and it is against these claims/assumptions that the bulk of the criticism of the whole RA approach has been directed.

Fred Dretske’s teleofunctional theory of content aims to simultaneously solve two ground-floor philosophical puzzles about mental content: the problem of naturalism and the problem of epiphenomenalism. It is argued here that his theory fails on the latter score. Indeed, the theory insures that content can have no place in the causal explanation of action at all. The argument for this conclusion depends upon only very weak premises about the nature of causal explanation. The difficulties Dretske’s theory encounters indicate the severe (...) challenges involved in arriving at a robust naturalistic understanding of content. (shrink)

What is the relationship between trying, desire, and desiring to try? Is it necessary to desire to do something in order to try to do it? Must Dave desire to quit smoking in order to try to quit? I shall defend the view that desiring to do A is necessary for trying to do A. First, Dave needs motivation to quit smoking and motivation comes in the form of desire. So it seems straightforward that when one tries to do something (...) A, one’s desire to do that thing A is one’s motivation. Second, when Dave throws out a pack of cigarettes, this may or may not be part of an attempt to quit smoking. It may be a political protest against R.J.R. Nabisco. Dave’s throwing out the cigarettes only counts as part of his attempt to quit smoking, if it is done for the right reason, out of the right motivation. Again, the right motivation seems to be the desire to quit smoking. Thus, the desire to do A appears to play important roles in the attempt to do A. At the very least, it helps to motivate, guide, and constitute the attempt as the attempt to do A. It is because Dave wants to quit smoking that his throwing out his cigarettes counts as part of his attempt to quit smoking, not as a political protest. (shrink)
