A venerable view, still very much alive, holds that human action is to be explained at least in part in terms of beliefs and desires. Those who advocate the view expect that the psychological theory which explains human behavior will invoke the concepts of belief and desire in a substantive way. I will call this expectation the belief-desire thesis. Though there would surely be a quibble or a caveat here and there, the thesis would be endorsed by an exceptionally heterogeneous collection of psychologists and philosophers ranging from Freud and Hume, to Thomas Szasz and Richard Brandt. Indeed, a number of philosophers have contended that the thesis, or something like it, is embedded in our ordinary, workaday concept of action. If they are right, and I think they are, then insofar as we use the concept of action we are all committed to the belief-desire thesis. My purpose in this paper is to explore the tension between the belief-desire thesis and a widely held assumption about the nature of explanatory psychological theories, an assumption that serves as a fundamental regulative principle for much of contemporary psychological theorizing. This assumption, which for want of a better term I will call the principle of psychological autonomy, will be the focus of the first of the sections below. In the second section I will elaborate a bit on how the belief-desire thesis is to be interpreted, and try to extract from it a principle that will serve as a premise in the argument to follow. In the third section I will set out an argument to the effect that large numbers of belief-desire explanations of action, indeed perhaps the bulk of such explanations, are incompatible with the principle of autonomy. Finally, in the last section, I will fend off a possible objection to my argument. In the process, I will try to make clear just why the argument works and what price we should have to pay if we were resolved to avoid its consequences.

Eliminativism has been a major focus of discussion in the philosophy of mind for the last two decades. According to eliminativists, beliefs and other intentional states are the posits of a folk theory of mind standardly called "folk psychology". That theory, they claim, is radically false and hence beliefs and other intentional states do not exist. We argue that the expression "folk psychology" is ambiguous in an important way. On the one hand, "folk psychology" is used by many philosophers and cognitive scientists to refer to an internally represented theory of human psychology exploited in the prediction of behavior. On the other hand, "folk psychology" is used to refer to the theory of mind implicit in our everyday talk about mental states. We then argue that sorting out the conceptual and terminological confusion surrounding "folk psychology" has major consequences for the eliminativism debate. In particular, if certain models of cognition turn out to be true, then on some readings of "folk psychology" the arguments for eliminativism collapse.

Fred Dretske began his review of my book, The Fragmentation of Reason, with the warning that it would ‘get the adrenalin pumping’ if you are a fan of episte- mology in the analytic tradition (Dretske 1992). Well, if my book got the adrenalin pumping, this one will make your blood boil. Bishop and Trout (B&T) adopt the label ‘Standard Analytic Epistemology (SAE)’ for ‘a contin- gently clustered class of methods and theses that have dominated English- speaking epistemology for much of the past century’(p. 8), and they make a spirited case for the view that SAE should be abandoned; it’s just not worth doing. According to B&T, ‘the main problem with SAE is methodological: its goals and methods are beyond repair’ (p. 22). For them, the primary goal of an epistemology worth having is prescriptive; it should tell us how to go about the business of reasoning. They are ‘driven by a vision of what epistemology could be —normatively reason guiding and genuinely capable of benefiting the world’ (p. 7). For the most part, they maintain, SAE does not even try to guide..
