I raise some doubts about the plausibility of Stanley and Williamson's view that all knowledge-how is just a species of propositional knowledge. By tackling the question of what is involved in entertaining a proposition, I try to show that Stanley and Williamson's position leads to an uncomfortable dilemma. Depending on how we understand the notion of contemplating a proposition, either intuitively central cases of knowing-how cannot be thus classified or we lose our grip on the very idea of propositional knowledge, which then fails to demarcate any clear class of cases. I conclude with a brief discussion of the nature and role of knowledge-how, and its relation to the important, but less explored, notion of expertise.

Let’s consider the following paradox (Fodor [1989], Jackson and Petit [1988] [1992], Drestke [1988], Block [1991], Lepore and Loewer [1987], Lewis [1986], Segal and Sober [1991]): i) The intentional content of a thought (or any other intentional state) is causally relevant to its behavioural (and other) effects. ii) Intentional content is nothing but the meaning of internal representations. But, iii) Internal processors are only sensitive to the syntactic structures of internal representations, not their meanings. Therefore it seems that if we want to defend the idea -absolutely plausible from an intuitive point of view- that mental / intentional states are causally responsible for behavioural outputs and we want to do it on the physicalist basis of any scientific methodology, we will have to give up the conviction that such intentional states qua intentional, i. e. as having a particular meaning, are the ones causally responsible for our behaviour. The path that takes us to mental epiphenomenalism is clear: 1) the causal powers of any event are completely determined by its physical properties; 2) although intentional properties supervene on physical properties, they can’t be identified with them; 3) intentional properties, as intentional, are not causally responsible for behaviour, because they don’t take part in the causal powers of the states to which they belong, i. e., intentional properties are epiphenomenal. Let’s consider now a different yet parallel position to the one just described. There is an important debate in cognitive science about whether the class of mechanisms to which we belong and which the computational modelling project of cognitive processes refers to is best represented by classical or connectionist approaches (McClelland, Rumelhart et. al [1986], Smolensky [1987] [1988], Fodor and Pylyshyn [1988], Pinker and Prince [1988], Clark [1989], Ramsey, Stich and Rumelhart [1991], Clark and Karmiloff-Smith [forthcoming]).In classical, serial processing models, information is encoded in terms of rules that have a linguistic character. In connectionist or parallel distributed processing (PDP) models, the causal relationships among the units that constitute the system determine how the information is processes by the network, although these units don’t have a direct semantic interpretation. But, for both, classical and connectionist models, all the computations can be explained without any reference to the content of the processed information, i.e., in both cases the properties that seem to be responsible for the system’s behaviour are ultimately physical properties nor intentional ones. This situation mirrors thus, within cognitive science, the philosophical discussion concerning the causal efficacy of semantic properties. Now, if in this debate we opt for the classical paradigm, there is a way of finding a solution to the computational version of the epiphenomenalism paradox. This solution is based mainly on the notion of supervenience or, more precisely, on the notion of mereological supervenience (Kim [1984] [1988])1 . The idea of intentional properties supervening on physical properties makes sense within the classical context because there exists an easily isolable supervenience base comprising the syntactic items in the socalled language of thought. But, what happens if we opt for the connectionist paradigm?. The situation here doesn’t seem to favour the use of the same supervenience strategy. For it has been argued (Ramsey, Stich and Garon [1991]) that beliefs, desires, and other mental states are nor, in the connectionist paradigm, individuable as weight or activation states of the system. This is because information is encoded by the network in distributed and superpositional representations, i.e., there are no straightforwardly isolable vehicles at the physical level that can be identified as the articulated supervenience base on which the semantic properties supervene2 . If this is true, then the connectionist not only loses the battle against epiphenomenalism but more drastically, seems to offer a standing invitation to eliminativism, since talk of beliefs and desires, etc. now seems to be floating free of any acceptable scientific underpinning, i.e., she has lost the necessary theoretical apparatus for supporting the intuitive idea that propositional attitudes -beliefs, desires and any mental states with semantic content- are physically realized. This second line of argumentation doesn’t take us to a paradox but to a dilemma: either we accept eliminativism, if connectionist hypothesis are correct or we defend the causal efficacy of mental states with semantic content by showing that, after all, connectionist networks are not plausible cognitive models (Davies [1991]). From my point of view, however, both lines of argumentation need to be revised. The aim of this paper is to find an account of the causal efficacy of content that avoids the aforementioned epiphenomenalist objections and that doesn’t require the discovery of inner symbols in the computational modelling of such contentful mental states. In short, the aim is to find a meeting point where a philosophical story about content and cause and the connectionist computational model can be brought together (Cfr. Clark [1989]).

Dual factor theories of meaning are fatally flawed in at least two ways. First. their very duality constitutes a problem: the two dimensions of meaning (reference and conceptual role) cannot be treated as totally orthogonal without compromising the intuition that much of our linguistic and non linguistic behavior is based on the cognizer’s interaction with the world. Second, Conceptual Role Semantics is not adequate for explaining a crucial feature of linguistic representation, viz., the special kind of compositionality known as concatenative compositionality. Dual factor theories, I conclude, cannot constitute an acceptable philosophical model of content.

In a recent paper, Paul Coates defends a sophisticated dispositional account which allegedly resolves the sceptical paradox developed by Kripke in his monograph on Wittgenstein's treatment of following a rule (Kripke, 1982). Coates' account appeals to a notion of 'homeostasis', unpacked as a subject's second-order disposition to maintain a consistent pattern of extended first-order dispositions regarding her linguistic behavior. This kind of account, Coates contends, provides a naturalistic model for the normativity of intentional properties and thus resolves Kripke's sceptical paradox. In this paper I argue that Coates' second-order dispositional account cannot solve the sceptic's problems regarding meaning and normativity. My main contention is that in order for second-order dispositions to be able to effectively regulate the coordinated responses constitutive of first-order dispositions, those first order dispositions must be independently identifiable. Yet that's precisely what Kripke's sceptical argument calls into question. I shall also argue, in a more positive fashion, that Coates' own appeal to practical breakdowns may suggest a different —and more effective— response to the sceptic's concern

The paper has a negative and a positive side. The negative side argues that the classical notions of narrow and wide content are not suitable for the purposes of psychological explanation. The positive side shows how to characterize an alternative notion of content that is suitable for those purposes. This account is supported by a way of conceptualizing computation that is constitutively dependent upon properties external to the system and empirical research in developmental psychology. My main contention is that an adequate computational explanation of the behavior involved in cognitive activities should invoke a concept of content that can capture the intimate dynamical relationship between the inner and the outer. The notion of content thus reaches out to include the set of skills, abilities and know-hows that an agent deploys in a constantly variable environment. The assumption underlying my attempt to characterize this ecological notion of content is that cognition is better understood when treated as embedded cognition and that the idea of cognitive significance ought to be cashed out in non-individualistic and pragmatic terms.

In this paper I argue on two fronts. First, I press for the view that judging is a type of mental action, as opposed to those who think that judging is involuntary and hence not an action. Second, I argue that judging is specifically a type of non-voluntary mental action. My account of the non-voluntary nature of the mental act of judging differs, however, from standard non-voluntarist views, according to which ‘non-voluntary’ just means regulated by epistemic reasons. In addition, judging is non-voluntary, I contend, because it is partially constituted by the exercise of a non-reason-governed skill. This skill, which I call ‘critical pop-out’, consists of an unreflective, often unconscious, ability to detect the kind of situations in which the reflective abilities that also partially constitute our acts of judging should be deployed. We are responsible for our judgments, I conclude, because in identifying such reflection-inviting situations, we reveal the kind of epistemic agents we are

I argue that findings in support of Adams and Kveraga’s functional forecast model of emotion expression processing help settle the debate between rich and sparse views of the content of perceptual experience. In particular, I argue that these results in social vision suggest that the distinctive phenomenal character of experiences involving high-level properties such as emotions and social traits is best explained by their being visually experienced as opposed to being brought about by perceptual judgments

Nonconceptualists maintain that there are ways of representing the world that do not reflect the concepts a creature possesses. They claim that the content of these representational states is genuine content because it is subject to correctness conditions, but it is nonconceptual because the creature to which we attribute it need not possess any of the concepts involved in the specification of that content. Appeals to nonconceptual content have seemed especially useful in attempts to capture the representational properties of perceptual experiences, the representational states of pre-linguistic children and non-human animals, the states of subpersonal visual information-processing systems, and the subdoxastic states involved in tacit knowledge of the grammar of a language. Nonconceptual content is also invoked in the explanation of concept possession, concept acquisition, sensorimotor behaviour, and in the analysis of the notion of self-consciousness. The notion of nonconceptual content plays an important role in many discussions about the relationships between perception and thought.

This paper concerns the role of the structural properties of representations in determining the nature of their content. I take as a starting point Fodor's (2007) and Heck's (2007) recent arguments making the iconic structure of perceptual representations essential in establishing their content as content of a different (nonconceptual) kind. I argue that the prima facie state–content error this strategy seems to display is nothing but a case of “state–content error error,” i.e., the mistake of considering that the properties that characterize the type of content certain representations have are indeed independent of their structural properties. I also consider another objection to the general strategy, namely that it falls short of showing that the nonconceptual content of perceptual experiences thus established is the kind of content that figures in true explanations of intentional behavior. I concede this point in respect of Fodor's version of the strategy, while denying that it has any bearing on Heck's approach. The success of this objection in Heck's case ultimately depends, I argue, upon an unjustified commitment to a certain empirically suspect model of perception.

In this paper I attempt to develop a notion of responsibility (semantic responsibility) that is to the notion of belief what epistemic responsibility is to the notion of justification. 'Being semantically responsible' is shown to involve the fulfilment of cognitive duties which allow the agent to engage in the kind of reason-laden discourses which render her beliefs appropriately sensitive to correction. The concept of semantic responsibility suggests that the notion of belief found in contemporary philosophical debates about content implicitly encompasses radically different classes of beliefs. In what follows I make those different types explicit, and sketch some implications for naturalisation projects in semantics and for accounts of the (putative) non-conceptual content of perceptual experiences

On the Origin of Objects is, at heart, an extended search for a non-circular and nonreductive characterization of two key notions: intentionality and computation. Only a non-circular and non-reductive account of these key notions can, Smith believes, provide a secure platform for a proper understanding of the mind. The project has both a negative and a positive aspect. Negatively, Smith rejects views that attempt to identify the key notions with lower-level physical properties, arguing instead for a more abstract and systemic understanding. This negative effort occupies Part I of the book. In Part II, we encounter the positive side of Smith's proposal: an attempt to develop a non-reductive analysis of computation and meaning able to meet the requirements laid out in Part I. One purpose of this critical review is to lay out this project in fairly simple terms. This is necessary since Smith's own treatment and prose sometimes obscures the flow of the argument. I suggest that, properly understood, Smith's proposal bears a clear affinity to ideas emerging from the dynamical systems movement within Cognitive Science, and that this tie-in can help put flesh on several of the more metaphorical characterizations in the book. My main criticism is that the book ultimately fails to provide an account able to meet Smith's own requirements for a truly non-reductive account of intentionality. This is especially the case regarding Smith's commitment to licensing a partition of the world based on no a priori assumptions whatsoever. The exercise is a valuable one, however, since it forces us to look harder at some foundational assumptions and at least hints at a new and refreshing perspective: one in which the key explanatory relations are grounded in facts about human practice and pragmatically established social norms.

One common factor underlying the set of disciplines clustered together under the label of Cognitive Science is a computational model of the mind. Cognitive capacities are to be treated as information-processing operations and to be characterized in computational terms. Computational processes are defined, in turn, in terms of operations on representations. For a few years, one of the most important debates in Cognitive Science has been whether the class of mechanisms to which cognizers belong and to which the computational modelling project of cognitive processes refers is best represented by classical or connectionist approaches. In either a classical or connectionist fashion though, the cognitive scientific style has remained computational all the way through.

The contents of perceptual experience, it has been argued, often include a characteristic “non-conceptual” component (Evans, 1982). Rejecting such views, McDowell (1994) claims that such contents are conceptual in every respect. It will be shown that this debate is compromised by the failure of both sides to mark a further, and crucial, distinction in cognitive space. This is the distinction between what is doubted here as mindful and mindless modes of perceiving: a distinction which cross-classifies the conceptual / non-conceptual divide. The goal of the paper is to show that there can be both mindful personal level perceptual experiences whose content cannot be considered conceptual — pace McDowell (1994)— and that there are mindless personal level perceptual experiences whose content cannot be considered —pace Evans (1982)— nonconceptual. The resulting picture yields a richer four dimensional carving of the space of perceptual experience, and provides a better framework in which to accommodate the many subtleties involved in our sensory confrontations with the world
