This book revives the study of conventional implicatures in natural language semantics. H. Paul Grice first defined the concept. Since then his definition has seen much use and many redefinitions, but it has never enjoyed a stable place in linguistic theory. Christopher Potts returns to the original and uses it as a key into two presently under-studied areas of natural language: supplements and expressives. The account of both depends on a theory in which sentence meanings can be multidimensional. The theory (...) is logically and intuitively compositional, and it minimally extends a familiar kind of intensional logic, thereby providing an adaptable, highly useful tool for semantic analysis. The result is a linguistic theory that is accessible not only to linguists of all stripes, but also philosophers of language, logicians, and computer scientists who have linguistic applications in mind.

A dissertation in the tradition of logical positivism includes a discussion of the functions and methods of philosophy and a critique of ethics and theology.

The phenomenon of disagreement has recently been brought into focus by the debate between contextualists and relativist invariantists about epistemic expressions such as ‘might’, ‘probably’, indicative conditionals, and the deontic ‘ought’. Against the orthodox contextualist view, it has been argued that an invariantist account can better explain apparent disagreements across contexts by appeal to the incompatibility of the propositions expressed in those contexts. This paper introduces an important and underappreciated phenomenon associated with epistemic expressions — a phenomenon that we call (...) reversibility. We argue that the invariantist account of disagreement is incompatible with reversibility, and we go on to show that reversible sentences cast doubt on the putative data about disagreement, even without assuming invariantism. Our argument therefore undermines much of the motivation for invariantism, and provides a new source for constraints on the proper explanation of purported data about disagreement. (shrink)

Moral realism and antirealist-expressivism are of course incompatible positions. They disagree fundamentally about the nature of moral states of mind, the existence of moral states of affairs and properties, and the nature and role of moral discourse. The central realist view is that a person who has or expresses a moral thought is thereby in, or thereby expresses, a cognitive state of mind; she has or expresses a belief that represents a moral state of affairs in a way that might (...) be accurate or inaccurate. The view of antirealist-expressivism is that such a person is in, or expresses, a conative state of mind, one that consists in a certain kind of attitude or motivational stance toward something, such as an action or a person. Realism holds that moral thoughts have truth conditions and that in some cases these truth conditions are satisfied so that our moral thoughts are true. Antirealist-expressivism holds, to a first approximation, that the distinctive moral content of a moral thought does not have truth conditions. (shrink)

Provides a comprehensive introduction to the major philosophical theories attempting to explain the workings of language.

Epistemic modal operators give rise to something very like, but also very unlike, Moore's paradox. I set out the puzzling phenomena, explain why a standard relational semantics for these operators cannot handle them, and recommend an alternative semantics. A pragmatics appropriate to the semantics is developed and interactions between the semantics, the pragmatics, and the definition of consequence are investigated. The semantics is then extended to probability operators. Some problems and prospects for probabilistic representations of content and context are explored.

In chapter five of Wise Choices, Apt Feelings Allan Gibbard develops what he calls a ‘normative logic’ intended to solve some problems that face an expressivist theory of norms like his. The first is “the problem of embedding: The analysis applies to simple contexts, in which it is simply asserted or denied that such-and-such is rational. It says nothing about more complex normative assertions.”1 That is the problem with which I will be concerned. Though he doesn’t list it as one (...) of the problems to be solved, Gibbard’s devices also explain what it means to say that a certain normative argument is ‘valid’, that one normative statement follows from some others. Both of these questions arise because of the ways we ordinarily think and speak, ways which on a simplistic version of expressivism appear not to make any sense. An expressivist committed to making sense of the way we ordinarily think and speak in normative language owes some account of embeddings and of logic. Gibbard’s device seems to me the clearest and most systematic of any expressivist attempt to meet these challenges. (shrink)

Even if non-cognitivists about some subject-matter can meet Geach’s challenge to explain how there can be valid implications involving sentences which express non-cognitive attitudes, they face a further problem. I argue that a non-cognitivist cannot explain how, given a valid argument whose conclusion expresses a belief and at least one of whose premises expresses a non-cognitive attitude, it could be reasonable to infer the conclusion from the premises.

Geach's problem, the problem of accounting for the fact that judgements expressed using moral terms function logically like other judgements, stands in the way of most noncognitive analyses of moral judgements. The non-cognitivist must offer a plausible interpretation of such terms when they appear in conditionals that also explains their logical interaction with straightforward moral assertions. Blackburn and Gibbard have offered a series of accounts each of which interprets such conditionals as expressing higher order commitments. Each then invokes norms for (...) the coherent acceptance of attitudes to explain why we hold certain combinations inconsistent. Against these accounts the paper presses two related objections: (1) The norms needed to do the explanatory work cannot be strong enough to do that work without also ruling clearly consistent attitudes inconsistent. And (2), the norms of rational attitude acceptance do not neatly track the distinction between consistent and inconsistent attitudes. (shrink)

: In recent literature supporting a hybrid view between metaethical cognitivism and noncognitivist expressivism, much has been made of an analogy between moral terms and pejoratives. The analogy is based on the plausible idea that pejorative slurs are used to express both a descriptive belief and a negative attitude. The analogy looks promising insofar as it encourages the kinds of features we should want from a hybrid expressivist view for moral language. But the analogy between moral terms and pejorative slurs (...) is also problematic. In this paper, I argue for two main ways in which we should distinguish between two different types of pejorative terms: slurs, on the one hand, and what I call general pejorative terms, on the other. I examine the problems with the analogy between slurs and moral terms and conclude that general pejorative terms like ‘jerk’ are a better candidate on which to model the potential dual-use behavior of moral terms. So if hybrid theorists are looking for a dual-use model for moral language, they should be careful to base their analogies on general pejoratives, rather than slurs. (shrink)

Non-cognitivism might seem to offer a plausible account of evaluative judgments, at least on the assumption that there is a satisfactory solution to the Frege-Geach problem. However, Cian Dorr has argued that non-cognitivism remains implausible even assuming that the Frege-Geach problem can be solved, on the grounds that non-cognitivism still has to classify some paradigmatically rational inferences as irrational. Dorr's argument is ingenious and at first glance seems decisive. However, in this paper I will show that Dorr's argument equivocates between (...) two different notions of evidence, and that once this equivocation is noted there is no reason to doubt that non-cognitivism is consistent with the rationality of such inferences, at least if it is assumed that the Frege-Geach problem can be solved. In particular, I will show that non-cognitivists can endorse the same explanation of the rationality of such inferences that cognitivists should endorse, and that there is thus no need for non-cognitivists to offer any sort of idiosyncratic account of the epistemology of such cases, in contrast to what other commentators on Dorr's argument have thought.

It has recently been argued by Cian Dorr that if noncognitivism is true, inferences to factual conclusions from premises at least one of which is moral must be condemned as irrational. For, given a noncognitivist understanding of what it is to accept such premises, such reasoning would be wishful thinking: irrationally revising our views about the world to make them cohere with our desires and feelings. This he takes to be a reductio of noncognitivism. I argue that no compelling case (...) to this effect has been made out. I show how, in many cases, non-cognitivists can make excellent sense of the rational legitimacy of such arguments. In cases where they plausibly cannot do so, moreover, this legitimacy is highly doubtful for independently plausible reasons and should be doubted even by cognitivists. (shrink)
