A central tenet of cognitivism is that knowing how is to be explained in terms of tacitly knowing that a theory is true. By critically examining canonical anti-behaviorist arguments and contemporary appeals to tacit knowledge, I have devised a more explicit characterization in which tacitly known theories must act as justifiers for claims that the tacit knower is capable of explicitly endorsing. In this manner the new account is specifically tied to verbal behavior. In addition, if the analysis is correct (...) then it follows that the scope and nature of cognitivist appeals to tacit knowledge are largely mistaken. (shrink)

Humans grasp discrete infinities within several cognitive domains, such as in language, thought, social cognition and tool-making. It is sometimes suggested that any such generative ability is based on a computational system processing hierarchical and recursive mental representations. One view concerning such generativity has been that each of the mind’s modules defining a cognitive domain implements its own recursive computational system. In this paper recent evidence to the contrary is reviewed and it is proposed that there is only one supramodal (...) computational system with recursion in the human mind. A recursion thesis is defined, according to which the hominin cognitive evolution is constituted by a recent punctuated genetic mutation that installed the general, supramodal capacity for recursion into the human nervous system on top of the existing, evolutionarily older cognitive structures, and it is argued on the basis of empirical evidence and theoretical considerations that the recursion thesis constitutes a plausible research program for cognitive science.

Fodor (1975) proposed that word meanings were atomic, and that meaning relations between words could be captured by inference rules, or 'meaning postulates', linking atomic concepts. In his recent work, however, Fodor has rejected meaning postulates as a way of capturing meaning relations, because he sees no principled way of distinguishing meaning postulates from empirical knowledge. In this paper, I argue that Fodor is wrong to reject meaning postulates.

Grice (1957) drew a distinction between natural(N) and non–natural(NN) meaning, and showed how the latter might be characterised in terms of intentions and the recognition of intentions. Focussing on the role of natural signs and natural behaviours in communication, this paper makes two main points. First, verbal communication often involves a mixture of natural and non–natural meaning and there is a continuum of cases between showing and meaningNN. This suggests that pragmatics is best seen as a theory of intentional verbal (...) communication rather than a theory of meaningNN. Second, some natural behaviours have a signalling function: they are, in effect, natural codes. Such behaviours do not fit easily into Grice's distinction between natural and non–natural meaning, which suggests it is not exhaustive. (shrink)

Cohen (1981) and others have made an interesting argument for the thesis that humans are rational: normative principles of reasoning and actual human reasoning ability cannot diverge because both are determined by the same process involving our intuitions about what constitutes good reasoning as a starting point. Perhaps the most sophisticated version of this argument sees reflective equilibrium as the process that determines both what the norms of reasoning are and what actual cognitive competence is. In this essay, I will (...) evaluate both the general argument that humans are rational and the reflective equilibrium argument for the same thesis. While I find both accounts initially appealing, I will argue that neither successfully establishes that humans are rational. (shrink)

The conception of a modular structure of mind, which postulates that the mind is composed of more or less autonomous subsystems, is widespread in contemporary psychology. Proponents of a modular structure of the mind, such as Marshall (1980; 1984; 1985), Fodor (1983), Gardner (1983), and Shallice (1988), have linked their work to F. J. Gall's theory of organology or of the “functions of the brain”. This paper argues: (1) Gall's organology defends a view of the capacities of the mind that (...) relies on a specific relation between the organism and its organs. The organs of Gall stem from and originate “needs” so that they embody not so much processing capacities, but perception-for-action cycles. (2) Modules and organs arise at different levels of description that cannot be easily matched. (3) It is just this central distinction between organs and modules which explains the inherent relation between organology, comparative biology and differential psychology on the one hand and modularity and cognitive science on the other.
