In this paper, I investigate the prospects for using the distinction between rejection and denial to resolve Saul Kripke’s puzzle about belief. One puzzle Kripke presents in A Puzzle About Belief poses what would have seemed a fairly straightforward question about the beliefs of the bilingual Pierre, who is disposed to sincerely and reflectively assent to the French sentence Londres est jolie, but not to the English sentence London is pretty, both of which he understands perfectly well. The question to be answered is whether Pierre believes that London is pretty, and Kripke argues, of each answer, that it is unacceptable. On my proposal, either answer to the question is to be rejected, but neither answer is to be denied, using the resource of partially-defined predicates. After demonstrating how this serves as a solution to the puzzle, I illustrate some philosophical motivations—independent of Kripke’s puzzle —for adopting a view on which belief is a partially defined predicate. I conclude that there are decent prospects for the proposed response to Kripke’s puzzle

David Hume fancied himself the Newton of the mind, aiming to reinvent the study of human mental life in the same way that Newton had revolutionized physics. And it was his view that the novel account of belief he proposed in his Treatise of Human Nature was one of that work’s central philosophical contributions. From the earliest responses to the Treatise forward, however, there was deep pessimism about the prospects for his account. It is easy to understand the source of this pessimism: The constraints he employed in theorizing stem from his Newtonian ambitions. Constraints such as his copy principle and his decision to rely only on variations in “force and vivacity” for differentiating types of mental states severely limit his available explanatory resources. However, it is one thing to regard an account as untenable, and quite another to understand where it fails. In this paper, I focus on one long-standing objection to Hume’s account — the objection that Hume cannot offer an account of negative belief or denial — as presented by Hume’s contemporary Thomas Reid, as well as more recently by Barry Stroud, and defend Hume from this objection. I argue that Hume both should and does endorse an account of negative belief based in relations of contrariety between contents, rather than between mental activities, and survey the different options available to Hume for spelling out an account of contrary contents

Smith proposes an account of how languages developed. He did so not as historian, but as a philosopher with a special concern about how a nominalist could account for general terms. Names for individuals are taken as fairly unproblematic – say ‘Thames’ and ‘Avon’ for each of the respective rivers. But whence the word ‘river,’ applicable to more than one, if all that exist are particular objects? Smith’s view is not the usual one, according to which people deploy a powerful ability to abstract mentally, and subsequently affix a label to a general concept. He resisted this because he granted that such robust mental processes themselves presuppose the use of words. Rather, what holds the class together is the word itself, a “single appellation.”

There is a tension between John Locke’s awareness of the fundamental importance of a shared public language and the manner in which his theorizing appears limited to offering a psychologistic account of the idiolects of individual speakers. I argue that a correct understanding of Locke’s central notion of signification can resolve this tension. I start by examining a long standing objection to Locke’s view, according to which his theory of meaning systematically gets the subject matter of our discourse wrong, by making our ideas the meanings of our words. By examining Locke’s definition of “truth”, I show that Lockean signification is an expression relation, rather than a descriptive or referential relation. Consequently, the sense in which our words signify our ideas is roughly that our utterances advertise our otherwise undisclosed mental lives to each other. While this resolves one aspect of the public/private tension, I close with a brief discussion of the remaining tension, and the role for normative constraints on signification to play in generating a genuinely shared public language.

Thomas Reid's philosophy of mind, epistemology, and philosophy of language all rely on his account of signs and signification. On Reid's view, some entities play a role of indicating other entities to our minds. In some cases, our sensitivity to this indication is learned through experience, whereas in others, the sensitivity is built in to our natural constitutions. Unlike representation, which was presumed to depend on resemblances and necessary connections, signification is the sort of relationship that can occur without any intrinsic ties between the sign and the thing signified. Of particular interest is the priority Reid gives to natural signs. Reid deploys his robust account of natural signs in a way that allows him to sidestep some skeptical worries common in the early modern period, as well as in grounding “artificial” human languages like English or Cantonese on a more basic human capacity for communication, that is, itself, the result of our sensitivity to natural signs of other people's minds.

In his Essays on the Intellectual Powers of Man, Thomas Reid offers a barrage of objections to the view, held by David Hume, that conceivability implies possibility. In this paper, I present Reid's first two objections to the ‘maxim of conceivability’ and defend Hume from them. The first objection concerns our ability to understand impossible claims, while the second concerns thoughts about impossible claims (such as, for instance, the thought that they are impossible). Reid's objections have special force against Hume because of his commitment to analyse all operations of the understanding in terms of conception. I argue that these objections fail, on the grounds that they presuppose substantive views about language which we are not warranted in attributing to Hume. Ultimately, Reid's objections help us draw out a set of intertwined issues about the language-mind relationship in Hume

Thomas Reid is notorious for rejecting the orthodox theory of conception (OTC), according to which conceiving of an object involves a mental relationship to an idea of that object. In this paper, I examine the question of what this rejection amounts to, when we limit our attention to bare conception (rather than the more widely discussed case of perception). I present some of the purported advantages of OTC, and assess whether they provide a genuine basis for preferring OTC to a Reidian alternative. I argue that Reid’s approach is no worse off than OTC at explaining intentionality of our conceptions, and suggest that OTC diverges less from Reid’s view than it would at first seem.

Philosophers have routinely taken a pessimistic view of the account of cognition offered by David Hume in his Treatise of Human Nature, claiming that Hume's limited explanatory resources cannot capture the rich complexity of our thought, judgment, and reasoning. I provide a qualified defense of Hume's attempt to analyze a cognitive activity in terms of objectual conception, ie conceiving or imagining an object. I defend Hume from objections offered by his contemporary Thomas Reid (and echoed by various recent Hume scholars), presenting an interpretation of the account that resolves these worries.

Philosophers have accused locke of holding a view about propositions that simply conflates the formation of a propositional thought with the judgment that a proposition is true, and charged that this has obviously absurd consequences.1 Worse, this account appears not to be unique to Locke: it bears a striking resemblance to one found in both the Port-Royal Logic (the Logic, for short) and the Port-Royal Grammar. In the Logic, this account forms part of the backbone of the traditional logic expounded in the text. As a result, the account’s alleged faults seem to seriously threaten the coherence and value of the whole approach to logic. And to the extent that Locke’s core philosophical commitments, in particular his ..
