Each of the three essays constituting the dissertation's body explores a theoretical approach to conceptual content, as well as to particular kinds of concepts. A concluding chapter defends a distinction between two varieties of intentionality. ;Chapter 1 identifies a distinctive model of intentionality in Locke's discussion of our "ideas of the sorts of substances." Properly understood, his doctrine of the "inadequacy" of substance-ideas reveals that the sort represented by such an idea isn't settled by the idea's descriptive content. The key to his compromise between classificatory conventionalism and essentialism is an injunction to "rectify" each substance-idea, one that reflects a norm governing natural-historical inquiry. Interestingly, Locke regards the resulting picture of the natural kinds represented by substance-ideas as compatible with his descriptivist account of how the extensions of substance-names are fixed. ;Chapter 2 examines Gupta and Belnap's theory of "circular concepts," which likewise appeals to a semantic "revision rule." Besides promising to explain semantic paradox when applied to the concept of truth, their theory significantly liberalizes the framework of truth conditional semantics. I criticize the rationale behind that liberalization by investigating the significance attributed to the revision rule, and propose invoking pragmatic ideas to do justice to some of the theory's motivating intuitions. ;Chapter 3 first argues that Brandom's appeal to normatively characterized linguistic practice subserves two approaches to content: one expressivist and the other reductionist. The criterion of adequacy motivating his "inferentialist" reduction of contentfulness, I then argue, is one he should dismiss in view of his deflationism about truth. Moreover, Brandom fails to vindicate the priority of attributions of inferential norms over attributions of propositional content. This criticism doesn't affect the expressivist elucidation of intentional concepts resulting from Brandom's normative-pragmatic description of assertional practice. ;My conclusion draws on this elucidation to defend a distinction prefigured in my construal of Locke as divorcing the aboutness of substance-ideas from assessments of truth. I argue that we should distinguish between a "representational" kind of intentionality whose attribution subserves explanations of successful inductive and explanatory practices, and a "semantic" kind whose attribution makes explicit normative features of the essentially communicative practice of assertion.

The revisionary approach to semantic paradox is commonly thought to have a somewhat uncomfortable corollary, viz. that, on pain of triviality, we cannot affirm that all valid arguments preserve truth (Beall2007, Beall2009, Field2008, Field2009). We show that the standard arguments for this conclusion all break down once (i) the structural rule of contraction is restricted and (ii) how the premises can be aggregated---so that they can be said to jointly entail a given conclusion---is appropriately understood. In addition, we briefly rehearse some reasons for restricting structural contraction.

This paper examines two explanations Sellars gives, at successive stages of his career, of how semantic vocabulary lets us relate linguistic expressions to extra-linguistic reality. Despite their differences, both explanations reveal a distinctive pragmatist approach. According to Sellars, we do not use semantic vocabulary to describe language-world relations. Rather, our taking language to relate to the world is implicit in the moves licensed by our semantic assertions. I argue that Sellars's discussions of the function of semantic vocabulary point to an overlooked position regarding the relation between the concepts of meaning and truth. According to him, the function of meaning ascriptions cannot be explained independently of the function of truth ascriptions. That is because the function of meaning ascriptions essentially involves licensing claims about the world when combined with truth ascriptions. If he is right, this poses a challenge to deflationary accounts of the function of truth talk.

Deflationists about truth seek to undermine debates about the nature of truth by arguing that the truth predicate is merely a device that allows us to express a certain kind of generality. I argue that a parallel approach is available in the case of logical consequence. Just as deflationism about truth offers an alternative to accounts of truth's nature in terms of correspondence or justification, deflationism about consequence promises an alternative to model-theoretic or proof-theoretic accounts of consequence's nature. I then argue, against considerations put forward by Field and Beall, that Curry's paradox no more rules out deflationism about consequence than the liar paradox rules out deflationism about truth.

This paper examines the pressures leading two very different Early Modern philosophers, Descartes and Locke, to invoke two ways in which thought is directed at objects. According to both philosophers, I argue, the same idea can simultaneously count as “of” two different objects—in two different senses of the phrase ‘idea of’. One kind of intentional directedness is invoked in answering the question What is it to think that thus-and-so? The other kind is invoked in answering the question What accounts for the success of our proper methods of inquiry? For Descartes as well as Locke, the two kinds of “ofness” come apart as a result of strong rationalist commitments. However, I will suggest that even if we reject such commitments, we go wrong if we assume that a single kind of intentional directedness suffices to address both questions.
