In this paper, we defend a traditional approach to semantics, that holds that the outputs of compositional semantics are propositional, i.e. truth conditions. Though traditional, this view has been challenged on a number of fronts over the years. Since classic work of Lewis, arguments have been offered which purport to show that semantic composition requires values that are relativized, e.g. to times, or other parameters that render them no longer propositional. Focusing in recent variants of these arguments involving quantification and binding, we argue that a correct understanding of how composition works gives no reason to relativize semantic values, and that propositional semantic values are in fact the preferred option. We take our argument to be mainly empirical, but along the way, we defend some more general theses. Simple propositional semantic values are viable in composition, we maintain, because composition is itself a complex phenomenon, involving multiple modes of composition. Furthermore, some composition principles make adjustments to the meanings of constituents in the course of composition. These adjustments are by triggered syntactic environments. We argue such small contributions of meaning from syntactic structure are acceptable.

Adult rat hypothalamo-pituitary axis and choroid plexus are rich in basic fibroblast growth factor which likely has a role in fluid homeostasis. Towards this end, we characterized the distribution and modulation of FGF2 in the human and rat central nervous system. To ascertain a functional link between arginine vasopressin and FGF2, a rat model of chronic dehydration was used to test the hypothesis that FGF2 expression, like that of AVP, is altered by perturbed fluid balance.Immunohistochemistry and confocal microscopy were used to examine the distribution of FGF2 and AVP neuropeptides in the normal human brain. In order to assess effects of chronic dehydration, Sprague-Dawley rats were water deprived for 3 days. AVP neuropeptide expression and changes in FGF2 distribution in the brain, neural lobe of the pituitary and kidney were assessed by immunohistochemistry, and western blotting.In human hypothalamus, FGF2 and AVP were co-localized in the cytoplasm of supraoptic and paraventricular magnocellular neurons and axonal processes. Immunoreactive FGF2 was associated with small granular structures distributed throughout neuronal cytoplasm. Neurohypophysial FGF2 immunostaining was found in axonal processes, pituicytes and Herring bodies. Following chronic dehydration in rats, there was substantially-enhanced FGF2 staining in basement membranes underlying blood vessels, pituicytes and other glia. This accompanied remodeling of extracellular matrix. Western blot data revealed that dehydration increased expression of the hypothalamic FGF2 isoforms of ca. 18, 23 and 24 kDa. In lateral ventricle choroid plexus of dehydrated rats, FGF2 expression was augmented in the epithelium but reduced interstitially.Dehydration altered FGF2 expression patterns in AVP-containing magnocellular neurons and neurohypophysis, as well as in choroid plexus epithelium. This supports the involvement of centrally-synthesized FGF2, putatively coupled to that of AVP, in homeostatic mechanisms that regulate fluid balance.

Belief in propositions has had a long and distinguished history in analytic philosophy. Three of the founding fathers of analytic philosophy, Gottlob Frege, Bertrand Russell, and G. E. Moore, believed in propositions. Many philosophers since then have shared this belief; and the belief is widely, though certainly not universally, accepted among philosophers today. Among contemporary philosophers who believe in propositions, many, and perhaps even most, take them to be structured entities with individuals, properties, and relations as constituents. For example, the proposition that Glenn loves Tracy has Glenn, the loving relation, and Tracy as constituents. What is it, then, that binds these constituents together and imposes structure on them? And if the proposition that Glenn loves Tracy is distinct from the proposition that Tracy loves Glenn yet both have the same constituents, what is about the way these constituents are structured or bound together that makes them two different propositions? In The Nature and Structure of Content, Jeffrey C. King formulates a detailed account of the metaphysical nature of propositions, and provides fresh answers to the above questions. In addition to explaining what it is that binds together the constituents of structured propositions and imposes structure on them, King deals with some of the standard objections to accounts of propositions: he shows that there is no mystery about what propositions are; that given certain minimal assumptions, it follows that they exist; and that on his approach, we can see how and why propositions manage to have truth conditions and represent the world as being a certain way. The Nature and Structure of Content also contains a detailed account of the nature of tense and modality, and provides a solution to the paradox of analysis. Scholars and students working in the philosophy of mind and language will find this book rewarding reading.

It is generally believed that natural languages have lots of contextually sensitive expressions. In addition to familiar examples like ‘I’, ‘here’, ‘today’, ‘he’, ‘that’ and so on that everyone takes to be contextually sensitive, examples of expressions that many would take to be contextually sensitive include tense, modals, gradable adjectives, relational terms (‘local’; ‘enemy’), possessives (‘Annie’s book’) and quantifi ers (via quantifier domains). With the exception of contextually sensitive expressions discussed by Kaplan [1977], there has not been a lot of discussion as to the mechanism whereby contextually sensitive expressions get their values in context, aside from vague references to speakers’ intentions. In a recent paper, I proposed a candidate for being this mechanism and defended the claim that it is such. Because, as I suggested, these issues have been most extensively discussed in the case of demonstratives, I focused on these expressions by way of contrasting the mechanism I proposed with others in the literature. In the present work, I simply state what I claim is the mechanism by means of which demonstratives secure semantic values in contexts without defending the claim that it is so. I then consider some claims made by Kent Bach, and arguments for those claims, which would undermine the account I propose of how demonstratives secure semantic values in context.

In The Principles of Mathematics, Bertrand Russell famously puzzled over something he called the unity of the proposition. Echoing Russell, many philosophers have talked over the years about the question or problem of the unity of the proposition. In fact, I believe that there are a number of quite distinct though related questions all of which can plausibly be taken to be questions regarding the unity of propositions. I state three such questions and show how the theory of propositions defended in my recent book The Nature and Structure of Content answers them.

At least since Russell’s influential discussion in The Principles of Mathematics, many philosophers have held there is a problem that they call the problem of the unity of the proposition. In a recent paper, I argued that there is no single problem that alone deserves the epithet the problem of the unity of the proposition. I there distinguished three problems or questions, each of which had some right to be called a problem regarding the unity of the proposition; and I showed how the account of propositions formulated in my book The Nature and Structure of Content [2007 Oxford University Press] solves each of these problems. In the present paper, I take up two of these problems/questions yet again. For I want to consider other accounts of propositions and compare their solutions to these problems, or lack thereof, to mine. I argue that my account provides the best solutions to the unity problems.

Like many, though of course not all, philosophers, I believe in propositions. I take propositions to be structured, sentence-like entities whose structures are identical to the syntactic structures of the sentences that express them; and I have defended a particular version of such a view of propositions elsewhere. In the present work, I shall assume that the structures of propositions are at least very similar to the structures of the sentences that express them. Further, I shall assume that ordinary names are devices of direct reference and contribute only their bearers to propositions, that n-place predicates contribute n-place properties or relations to propositions, and that verbs of propositional attitude contribute to propositions two-place relations between individuals and propositions. The broad outline of a framework that includes these assumptions is one that I think many, though again not all, philosophers of language find congenial. I am concerned here to investigate and explain, from the standpoint of this framework, a puzzling phenomenon. The explanation I give of the phenomenon could be adapted to fit with frameworks somewhat different from the one adopted here. I adopt the present framework in part simply for definiteness.

The dissertation is an attempt to provide a formal semantics for occurrences of anaphoric pronouns and definite descriptions whose quantifier antecedents occur in sentences other than those in which the anaphoric pronouns and descriptions themselves occur, . The predominant view of anaphoric pronouns whose quantifier antecedents occur in the same sentence as they do is that they function as bound variables . Chapter 1 of this dissertation is constituted by a series of arguments against a bound variable treatment of q - terms and the observation that the semantic behavior of q - terms is similar to that of certain singular terms in English arguments. Given the similarity of semantic behavior between the latter and q - terms, it seems plausible to suppose that a theory of the semantic behavior of these singular terms in English arguments would provide a model for the eventual production of a semantic theory of q - terms. In Chapter 2, a formal semantics for these singular terms in arguments is produced. In Chapter 3, a formal semantics for q - terms is produced, on the model of the semantics in Chapter 2. Finally, in Chapter 4 it is shown that the formal semantics of Chapter 3 can be extended to handle pronouns in discourses containing verbs of propositional attitudes such as 'wants', 'dreams' etc. It is also shown that some occurrences of sentences containing q - terms have truth conditions not expressible by any quantified first order sentence. One must use finite partially ordered quantifiers to express the truth conditions of such occurrences of sentences. ;The dissertation contains two appendices: the first is a technical discussion of the formal semantics of Hans Kamp which shows that his theory cannot accomodate the linguistic data mine is designed to handle. The second examines the views of Gareth Evans, Charles Chastain and Keith Donnellan on certain anaphoric pronouns

A central job for propositions is to be the objects of the attitudes. Propositions are the things we doubt, believe and suppose. Some philosophers have thought that propositions are sets of possible worlds. But many have become convinced that such an account individuates propositions too coarsely. This raises the question of how finely propositions should be individuated. An account of how finely propositions should be individuated on which they are individuated very finely is sketched. Objections to the effect that the account individuates propositions too finely are raised and responses to the objections are provided. It is also shown that theories that try to individuate propositions less finely have serious problems.

Though these expressions are often called “names of months”, there is good reason to hold that they are not names at all. Syntactically, these words behave as count nouns. They combine with determiners such as ‘every’, ‘many’, ‘exactly three’ etc. to form restricted quantifiers:3 (1) Every January I go skiing. (2) I spent many Januarys at Squaw Valley. (3) I wasted exactly three Januarys in Bakersfield. Like other count nouns, they can take relative clauses in constructions such as (1)-(3): (1a) Every January that you visited we went skiing. (2a) I spent many Januarys that I will never forget at Squaw Valley. (3a) I wasted three Januarys that seemed interminable in Bakersfield. They also combine with the copula, indefinite article and adjectival modifiers to form predicates in the way that other count nouns do: (4) The first full month I lived in Northern California was a pleasant July. Further, it is generally held that only constituents of the same syntactic category can be conjoined. And as the following example shows, ‘January’ can be conjoined with other count nouns:4 (5) All Januarys and funerals last too long. Thus distributional evidence strongly suggests that ‘January’, ‘February’, etc. are count nouns. Since in general we take count nouns to express properties, we ought to take ‘January’, ‘February’ etc. to express properties as well.5 We shall return to the question of what properties such words express below. For now, we shall stick with syntax
