A lot of us have given up on the idea that there will be a naturalistic account of the relation of semantic reference and so have resolved to formulate our theories of semantics and communication without appeal to semantic reference. Still, there is a resilient intuition to the effect that I know the extensions of the terms of my language. This paper explicates that intuition without yielding to it. The key idea is to give a “skeptical” account of what it is to “know the meaning” of a word, by which I mean an account of the status that is granted to a person in saying that he or she “knows the meaning” of a word.

In order to capture our intuitions about the logical consistency of sentences and the logical validity of arguments, a semantics for a natural language has to allow for the fact that different occurrences of a single bare demonstrative, such as “this”, may refer to different objects. But it is not obvious how to formulate a semantic theory in order to achieve this result. This paper first criticizes several proposals: that we should formulate our semantics as a semantics for tokens, not expressions, Kaplan’s idea that syntax associates a demonstration with each occurrence of a demonstrative, Braun’s idea that a context may specify shifts in context across the evaluation of the expressions in a sentence; and Predelli’s idea that we should countenance different classes of contexts. Finally, a solution is proposed that allows that a natural language persists across the addition of basic lexical items but defines logical properties in terms of language stages. A surprising result is that we do not need to think of demonstratives as taking different referents in different situations

Semantics deals with the literal meaning of sentences. Pragmatics deals with what speakers mean by their utterances of sentences over and above what those sentences literally mean. However, it is not always clear where to draw the line. Natural languages contain many expressions that may be thought of both as contributing to literal meaning and as devices by which speakers signal what they mean. After characterizing the aims of semantics and pragmatics, this chapter will set out the issues concerning such devices and will propose a way of dividing the labor between semantics and pragmatics. To semantics belongs the job of defining the conditions under which a sentence is true relative to a context. To pragmatics belongs the job of explicating the conditions under which a given context pertains to a given conversation.

Kripke's puzzle about rule-following is a form of the traditional problem of the nature of linguistic meaning. A skeptical solution explains not what meaning is but the role that talk of meaning plays in the linguistic community. Contrary to what some have claimed, the skeptical approach is not self-refuting. However, Kripke's own skeptical solution is inadequate. He has not adequately explained the conditions under which we are justified in attributing meanings or the utility of the practice of attributing meanings. An alternative skeptical solution may be founded on a nonepistemic conception of assertibility. Roughly, a sentence is assertible if it facilitates cooperation. The function of meaning-talk is to resolve certain sorts of conflicts in assertion. Attributions of meaning to persons outside the community may be a proper expression of a practice whose reason for being lies entirely within the community. -/- .

In recent years, many philosophers have supposed that perceptual representations have propositional content. A prominent rationale for this supposition is the assumption that perceptions may justify beliefs, but this rationale can be doubted. This rationale may be doubted on the grounds that there do not seem to be any viable characterizations of the belief-justifying propositional contents of perceptions. An alternative is to model perceptual representations as marks in a perceptual similarity space. A mapping can be defined between points in perceptual similarity space and points in an objective quality space. The correctness of perceptual representation can then be defined as a kind of accuracy of mapping rather than as the truth of a proposition. The phenomenon of seeing-as can be accounted for as a matter of the location of marks in perceptual similarity space relative to other marks in perceptual similarity space. Perceptual representations, on this account, will not justify beliefs, but they may nonetheless guide judgment.
