Most animals have mental states of one sort or another, but few species share our capacity for self-awareness. We are aware of our own mental states via introspection, and we are aware of the mental states of our fellow human beings on the basis of what they do and say. This chapter is not concerned with these traditional forms of mind-reading—forms whose origins predate the beginnings of recorded history—but with the prospects of a rather different and significantly more recent form (...) of ‘mind-reading’: the capacity to reliably ascribe mental states to a creature on the basis of information derived from information about their brain states.

Fodor advocates a view of cognitive processes as computations defined over the language of thought (or Mentalese). Even among those who endorse Mentalese, considerable controversy surrounds its representational format. What semantically relevant structure should scientific psychology attribute to Mentalese symbols? Researchers commonly emphasize logical structure, akin to that displayed by predicate calculus sentences. To counteract this tendency, I discuss computational models of navigation drawn from probabilistic robotics. These models involve computations defined over cognitive maps, which have geometric rather than logical (...) structure. They thereby demonstrate the possibility of rational cognitive processes in an exclusively non-logical representational medium. Furthermore, they offer much promise for the empirical study of animal navigation. (shrink)

The notion of representation has become ubiquitous throughout cognitive psychology, cognitive neuroscience and the cognitive sciences generally. This paper addresses the status of mental representations as entities that have been posited to explain cognition. I do so by examining similarities between mental representations and sense-data in both their characteristics and key arguments offered for each. I hope to show that more caution in the adoption and use of representations in explaining cognition is warranted. Moreover, by paying attention to problematic notions (...) of representations, a less problematic sense of representation might emerge. (shrink)

Fodor and Pylyshyn's critique of connectionism has posed a challenge to connectionists: Adequately explain such nomological regularities as systematicity and productivity without postulating a "language of thought" (LOT). Some connectionists like Smolensky took the challenge very seriously, and attempted to meet it by developing models that were supposed to be non-classical. At the core of these attempts lies the claim that connectionist models can provide a representational system with a combinatorial syntax and processes sensitive to syntactic structure. They are not (...) implementation models because, it is claimed, the way they obtain syntax and structure sensitivity is not "concatenative," hence "radically different" from the way classicists handle them. In this paper, I offer an analysis of what it is to physically satisfy/realize a formal system. In this context, I examine the minimal truth-conditions of LOT Hypothesis. From my analysis it will follow that concatenative realization of formal systems is irrelevant to LOTH since the very notion of LOT is indifferent to such an implementation level issue as concatenation. I will conclude that to the extent to which they can explain the law-like cognitive regularities, a certain class of connectionist models proposed as radical alternatives to the classical LOT paradigm will in fact turn out to be LOT models, even though new and potentially very exciting ones.

One would have thought that Fodor's justly famous computational views about the mind and his covariation approaches to content owed a lot to the twentieth century that he now reviles. On the other hand, a number of lines he pursues in the target article make one wonder whether he hasn’t perhaps changed his mind about those famous views. Specifically, I argue that his own theory of content is open to the very same objections he raises against ‘sorting’ theories, and that (...) the supposed circularity in implicit definitions of logical particles can easily be avoided by the very functional/computational definitions that he fathered decades ago. Fodor's rejection here of sorting and implicit definition does make one worry that he is now opting for what seems the only atomistic alternative that would seem to be left, the first‐person meaning mysticism of the very Cartesian sort he now claims to favor, but from which I would have thought twentieth century role and discrimination views were a welcome relief. Despite all these worries, however, I concede that one could probably do worse than assume for the nonce that meaning is atomic, or, anyway, unanalyzed, and get on with investigating the mind on that basis—but keeping the options open.

There is a salient contrast in how theoretical representations are regarded. Some are regarded as revealing the nature of what they represent, as in familiar cases of theoretical identification in physical chemistry where water is represented as hydrogen hydroxide and gold is represented as the element with atomic number 79. Other theoretical representations are regarded as serving other explanatory aims without being taken individually to reveal the nature of what they represent, as in the representation of gold as a standard (...) for pre-20th century monetary systems in economics or the representation of the meaning of an English sentence as a function from possible worlds to truth values in truth-conditional semantics. Call the first attitude towards a theoretical representation *realist* and the second attitude *instrumentalist*. Philosophical explanation purports to reveal the nature of whatever falls within its purview, so it would appear that a realist attitude towards its representations is a natural default. I offer reasons for skepticism about such default realism that emerge from attending to several case studies of philosophical explanation and drawing a general metaphilosophical moral from the foregoing discussion.

Frege's puzzle is a fundamental challenge for accounts of mental and linguistic representation. This piece surveys a family of recent approaches to the puzzle that posit representational relations. I identify the central commitments of relational approaches and present several arguments for them. I also distinguish two kinds of relationism—semantic relationism and formal relationism—corresponding to two conceptions of representational relations. I briefly discuss the consequences of relational approaches for foundational questions about propositional attitudes, intentional explanation, and compositionality.

According to Peacocke, concepts are individuated by their possession conditions, which are specified in terms of conditions in which certain propositions containing those concepts are believed. In support, Peacocke tries to explain what it is for a thought to have a structure and what it is for a belief to have a propositional content. I show that the possession condition theory cannot answer such fundamental questions. Peacocke’s theory founders because concepts are metaphysically fundamental. They individuate the propositions and thoughts containing (...) them, which in turn individuate the propositional attitudes that are relations to those propositions or thoughts. (shrink)

For all the inadequacies of empiricism that BonJour admirably sets out in his first three chapters, one wonders whether rationalism is any better off. I’m afraid I don’t find BonJour’s account reassuring. It seems to be precisely the one that has led so many to be wary of the a priori in the first place. I want here to reiterate the reasons for that wariness, and sketch what seems to me a more promising approach.

Je soutiens qu’accepter les explications réalistes intentionnelles du comportement cognitif conduit inévitablement à endosser l’hypothèse du langage de la pensée, et que cette position théorique est, par conséquent, largement répandue chez les philosophes de l’esprit. Au cours de la discussion, je propose un exposé succinct et précis de cette hypothèse et j’analyse une série d’exemples représentatifs de l’argumentation pro-LOT. Après avoir examiné deux cas de résistance à ce type de raisonnement, je conclus en montrant que le soutien accordé à la (...) LOT est empiriquement substantiel, en dépit de la flexibilité et du caractère incomplet de cette hypothèse. (shrink)
