I. Vague Properties and the Problem of Vagueness The philosophical problem of vagueness is to say what vagueness is in a way that helps to resolve the sorites paradox. Saying what vagueness is requires saying what kinds of things can be vague and in what the vagueness of each kind consists. Philosophers dispute whether things of this, that, or the other kind can be vague, but no one disputes that there are vague linguistic expressions. Among vague expressions, predicates hold a (...) special place in the problem of vagueness, for it’s their vagueness that is soritesgenerating. That puts the vagueness of predicates at the hub of the problem of vagueness, and there can be little doubt that we’ll be a short step from home if we can account for it. Any account of vagueness will of course require commitment to theses that are themselves foci of philosophical debate, but one can’t expect to get anywhere without taking on some as working hypotheses and then striving to say something that will be plausible if those hypotheses are plausible. One of the working hypotheses of this paper is that propositional attitudes and propositional speech acts are relations to propositions of some stripe or other, in the generic sense in which a proposition is an abstract, mind- and language-independent entity that has a truth condition, and has that truth condition both essentially and absolutely (i.e. without relativization to anything).1 The existence of propositions requires the existence of properties, in the generic sense in which a property is an abstract, mind- and language-independent entity that has an instantiation condition, and has that instantiation condition both essentially and absolutely. For present purposes it will be harmless to pretend that the propositions we believe and assert are Russellian propositions—structured entities whose basic constituents are the objects and properties our beliefs and speech acts are about. When a propositionalist speaks in loosey-goosey mode, she is apt to say that a sentence token is true just in case the proposition expressed in its utterance is true.. (shrink)
S produces the sounds “It’s snowing” in the presence of A, and A instantaneously comes to know that it’s snowing. S has communicated to, or told, A that it’s snowing, and, as a result of S’s speech act, A came to know that it was snowing. Philosophical interest in communication turns on four inter-related questions. The first is about the logical structure of communication, or, more specifically, about whether communication is a relation that holds among three things just in case (...) the first communicated the second to the third. The second is about the explication, or analysis, of communication. The third is about the role of communication in the explication of linguistic meaning. And the fourth is about how knowledge is acquired by communication. The questions are interrelated in that answers to any one question may constrain answers to one or more of the others. (shrink)
A single argument template—the EPH template—can be used to generate versions of the best known and most challenging skeptical problems. In his brilliantly groundbreaking book Knowledge and Its Limits, Timothy Williamson presents a theory of knowledge and evidence which he clearly intends to provide a response to skepticism in its most important forms. After laying out EPH skepticism and reviewing possible ways of responding to it, I show how elements of Williamson’s theory motivate a hitherto unexplored way of responding to (...) EPH-generated skeptical arguments. Then I offer reasons to doubt the correctness of Williamson’s response. (shrink)
SI is a paradox because it presents four appearances that cannot all be veridical: first, it appears to be valid—after all, it’s both classically and intuitionistically valid; second, its sorites premiss, (2), seems merely to state the obvious fact that in the sorites march from 2¢ to 5,000,000,000¢ there is no precise point that marks the cutoff between not being rich and being rich; third, premiss (1), which asserts that a person with only 2¢ isn’t rich, is surely true; and (...) fourth, the conclusion (3), which asserts that a person with 5,000,000,000¢—i.e. $50 million—isn’t rich, is surely false.

A central claim of Paul Horwich’s 1998 book Meaning was that meaning properties reduce to acceptance properties, where a meaning property is a property of the form e means m for x, e being “a word or phrase—whether it be spoken, written, signed, or merely thought (i.e. an item of ‘mentalese’)” (44); an acceptance property for an expression e relative to a person x is a relation of the form x is disposed to accept an e-containing sentence of (...) kind … in circumstances of kind ….

There are two things we must know in order to know what vagueness is. We must know what kinds of things can be vague. Evidently, predicate and sentence types can be vague, but what about tokens of those types? What about statements and other speech acts? What about abstract entities such as properties and propositions? And what about names and the boundaries of physical objects? Then, of course, for each kind of thing that can be vague, we must know in (...) what vagueness for that kind consists. Needless to say, that there are these two questions doesn’t mean that we should try to answer the first before trying to answer the second. (shrink)
David’s epistemic understanding of two-dimensional semantics has these two features. First, although he considers at least two construals of epistemically possible worlds, on one of them they are centered metaphysically possible worlds. Second, David intends epistemic two-dimensional semantics to yield a theory of propositional-attitude content, as well as having application to the semantics of natural language expressions. These two features come together in David’s “The Components of Content,” where he deploys the apparatus of epistemic two-dimensional semantics to provide an account (...) of propositional-attitude content, and where, for reasons of simplicity and familiarity, epistemically possible worlds are taken to be centered metaphysically possible worlds. My talk is about this account of content. (shrink)
To a first approximation, _propositional content_ is whatever _that-clauses_ contribute to what is ascribed in utterances of sentences such as Ralph believes _that Tony Curtis is alive_. Ralph said _that Tony Curtis is alive_. Ralph hopes _that Tony Curtis is alive_. Ralph desires _that Tony Curtis is alive_.
If we think in a lingua mentis, questions about relations between linguistic meaning and propositional-attitude content become questions about relations between meaning in a public language (p-meaning) and meaning in a language of thought (t-meaning). Whether or not the neo-Gricean is correct that p-meaning can be defined in terms of t-meaning and then t-meaning defined in terms of the causal-functional roles of mentalese expressions, it's apt to seem obvious that separate accounts are needed of p-meaning and t-meaning, since p-meaning, unlike (...) t-meaning, must be understood at least partly in terms of communication. Paul Horwich, however, claims that his ‘use theory of meaning’ provides a uniform account of all meaning in terms of ‘acceptance properties’ that, surprisingly, implicate nothing about use in communication. But it turns out that the details of his theory belie his claim about it. (shrink)
In his important book Knowledge and Practical Interests, Jason Stanley advances a proposal about knowledge and the semantics of knowledge ascriptions which he calls interest-relative invariantism. A theory of knowledge ascriptions of the form ‘A knows that S’ is invariantist.
Although there is a vast literature on whether propositional attitudes are relations to propositions, a crucial question that ought to lie at the heart of this debate is not often enough seriously addressed. This is the question of the contribution propositions make to the ways in which we benefit from having our propositional-attitude concepts, if those concepts are concepts of relations to propositions. Unless propositions can be shown to confer a benefit that no non-propositions could provide, we should probably doubt (...) whether propositional attitudes really are relations to propositions. I believe that propositional attitudes are relations to propositions and that the role played by them in our conceptual economy cannot be played by things of any other kind, and in this paper I try to say why. This paper, in other words, offers my answer to the question posed by my title. (shrink)
(1) The propositions we believe and say are _Russellian_ _propositions_: structured propositions whose basic components are the objects and properties our thoughts and speech acts are about. (2) Many singular terms.
The proper statement and assessment of Russell's theory depends on one's semantic presuppositions. A semantic framework is provided, and Russell's theory formulated in terms of it. Referential uses of descriptions raise familiar problems for the theory, to which there are, at the most general level of abstraction, two possible Russellian responses. Both are considered, and both found wanting. The paper ends with a brief consideration of what the correct positive theory of definite descriptions might be, if it is not the (...) Russellian theory.

Stephen Schiffer presents a groundbreaking account of meaning and belief, and shows how it can illuminate a range of crucial problems regarding language, mind, knowledge, and ontology. He introduces the new doctrine of 'pleonastic propositions' to explain what the things we mean and believe are. He discusses the relation between semantic and psychological facts, on the one hand, and physical facts, on the other; vagueness and indeterminacy; moral truth; conditionals; and the role of propositional content in information acquisition and explanation. (...) This radical new treatment of meaning will command the attention of everyone who works on fundamental questions about language, and will attract much interest from other areas of philosophy.

Fregeans hold that propositional attitudes are relations to structured propositions whose basic constituents are concepts, or modes of presentation, of the objects and properties our beliefs are about. It is widely thought that there are compelling objections to the Fregean theory of mental and linguistic content. However, as I try to show, these objections are met by the version of Frege’s theory which I call Pleonastic Fregeanism.

What is it for marks or sounds to have meaning, and what is it for someone to mean something in producing them? Answering these and related questions, Schiffer explores communication, speech acts, convention, and the meaning of linguistic items in this reissue of a seminal work on the foundations of meaning. A new introduction takes account of recent developments and places his theory in a broader context.
