1. Nathan Salmon paper is entitled with a question: are general terms rigid? He asks this question in way of engaging the issue of the extension of the notion of rigidity beyond the domain of singular terms. While singular terms has been the province of most of the discussion of this rigidity since Naming and Necessity, it is well known that Kripke saw the notion extending to at least certain general terms such as terms for natural kinds. Scott Soames has recently weighed in on this issue in the latter chapters of his book Beyond Rigidity. His conclusion is that although there are significant overlaps in the properties of singular and general terms, there is no direct extension of rigidity to the general terms, and that rigid designation is properly applied only to singular terms. Salmon disagrees. His view, based in part of views dating back to his book Reference and Essence, is that there is an extension to be had, one which allows the application of the standard Kripkean characterization of rigidity to be applied to both sorts of terms. Central to his thesis is a claim about the status of certain definite descriptions. In these remarks, I will try to outline the issues to which NS is reacting, and the proposal he posits in response. I will then consider in a more critical light his claim about definite descriptions, bringing to bear considerations of their grammar.

How many senses can a given name have, with its reference held fixed? One, more than one? One answer that most would agree to is that sense is unique for each utterance of a name, that is, that a name can have no more than one sense on any given occasion. But is sense unique in any stronger sense than this? The answer that is typically attributed to Frege is that there is not, that, as Tyler Burge puts it, 1 Frege “treats proper names as having different senses while applying to the same person.” There are a number of possibilities for the locus of this multiplicity of sense; the following remark by Ruth Marcus indicates the possibilities: “the sense of a term is whatever is grasped or understood by a speaker on a particular occasion of use and may vary from occasion to occasion as well as from speaker to speaker.”2 Of the views canvassed by Marcus, we can draw out a more conservative one, and one more extreme. On the more conservative view, Frege is holding that sense may vary from speaker to speaker; on the more extreme view, Frege holds not only this, but that sense may vary from context to context. Endorsements of the two views are not hard to find. For example, typical sorts of endorsement of the conservative view are found in Harold Noonan’s remark that “different senses [are] associated with the name ‘Aris-.

Syntax, in its most general sense, is the study of the structure of sentences in natural language. In this course, we will approach syntax from the perspective of generative transformational grammar, as pioneered through the work of Noam Chomsky, and developed over the past four decades. Our goals are three-fold. First, to understand the nature of language as viewed from the structural perspective, and to understand the sort of insight about language this perspective affords. Second, to understand the nature and application of certain empirical methods to theoretical hypotheses within linguistics. And third, to understand certain general principles or laws of language which can be elucidated from the structural perspective by the empirical methods. The material in the course primarily will be drawn from English, but occasional reference will be made to other languages (although no prior knowledge is presupposed).

The topic of this seminar will be the notion of language as it is employed in the philosophy of language. The seminar will be divided into two parts, of somewhat unequal length. The first part will be devoted to the change in the conception of language that marked the transition from structural linguistics to generative linguistics (the so-called "Chomskian revolution"). We will approach this not only as a chapter in the philosophy of language, but also as an important chapter in the philosophy of science, in large part because much of the discussion centers around to what extent, and how, the study of language can be understood as a scientific inquiry, continuous with the other natural sciences. From this discussion, which will be devoted to reading some of the classic literature from the mid-50's to the mid-70's (largely by Chomsky), an articulation of the subject matter of the study of language will emerge, and in particular this will involve an articulation of the relation of syntax, semantics and pragmatics. This will lead us to explore, in the second part of the seminar, the most influential work, that of Grice, especially in "Logic and Conversation" devoted to articulating this distinction.

It is a characteristically Fregean thesis that the sense expressed by an expression is the linguistic meaning of that expression. Sense can play this role for Frege since it meets fundamental desiderata for meaning, that it be universal and invariantly expressed and objectively the same for everyone who knows the language. It has been argued,1 however, that, as a general thesis about natural languages, the identi cation of sense and meaning cannot be sustained since it is in con ict with another characteristically Fregean thesis, that sense uniquely determines reference. The argument is quite simple and can be outlined as follows. Assume the two theses we have just stated.

Are Fregean thoughts compositionally complex and composed of senses? We argue that, in Begriffsschrift, Frege took 'conceptual contents' to be unstructured, but that he quickly moved away from this position, holding just two years later that conceptual contents divide of themselves into 'function' and 'argument'. This second position is shown to be unstable, however, by Frege's famous substitution puzzle. For Frege, the crucial question the puzzle raises is why "The Morning Star is a planet" and "The Evening Star is a planet" have different contents, but his second position predicts that they should have the same content. Frege's response to this antinomy is of course to distinguish sense from reference, but what has not previously been noticed is that this response also requires thoughts to be compositionally complex, composed of senses. That, however, raises the question just how thoughts are composed from senses. We reconstruct a Fregean answer, one that turns on an insistence that this question must be understood as semantic rather than metaphysical. It is not a question about the intrinsic nature of residents of the third realm but a question about how thoughts are expressed by sentences.
