Teleological theories of content are thought to suffer from two related difficulties. According to the problem of indeterminacy, biological function is indeterminate in the sense that, in the case of two competing interpretations of the function of an evolved mechanism, there is often no fact of the matter capable of determining which function is the correct one. Therefore, any attempts to construct content out of biological function entail the indeterminacy of content. According to the problem of transparency, statements of biological (...) function are transparent in that a statement of the form 'the function of evolved mechanism M is to represent Fs' can be substituted salva veritate by a statement of the form 'the function of evolved mechanism M is to represent Gs' provided that the statement 'F iff G' is counterfactual supporting. Therefore, any attempt to construct content out of biological function must fail to capture the intensionality of psychological ascriptions. This paper argues that the teleological account is undermined by neither of these problems. Failure to appreciate this point stems from a conflation of two types of proper function - organismic and algorithmic - possessed by an evolved mechanism. These functions underwrite attributions of content to distinct objects. The algorithmic proper function of a mechanism underwrites attributions of content to the mechanism itself, while the organismic proper function of a mechanism underwrites attribution of content to the organism that possesses the mechanism. However the problems of indeterminacy and transparency arise only if the attributions of content attach to the same object. (shrink)

In this paper I assess the explanatory role of internal representations in connectionist models of cognition. Focusing on both the internal‘hidden’units and the connection weights between units, I argue that the standard reasons for viewing these components as representations are inadequate to bestow an explanatorily useful notion of representation. Hence, nothing would be lost from connectionist accounts of cognitive processes if we were to stop viewing the weights and hidden units as internal representations.

Cognitivism in psychology and philosophy is roughly the position that intelligent behavior can (only) be explained by appeal to internal that is, rational thought in a very broad sense. Sections 1 to 5 attempt to explicate in detail the nature of the scientific enterprise that this intuition has inspired. That enterprise is distinctive in at least three ways: It relies on a style of explanation which is different from that of mathematical physics, in such a way that it is not (...) basically concerned with quantitative equational laws; the states and processes with which it deals are in the sense that they are regarded as meaningful or representational; and it is not committed to reductionism, but is open to reduction in a form different from that encountered in other sciences. Spelling these points out makes it clear that the Cognitivist study of the mind can be rigorous and empirical, despite its unprecedented theoretical form. The philosophical explication has another advantage as well: It provides a much needed framework for articulating questions about whether the Cognitivist approach is right or wrong. The last three sections take that advantage of the account, and address several such questions, pro and con. (shrink)
