This paper presents a semantic and pragmatic theory of complex demonstratives. According to this theory, the semantic content of a complex demonstrative, in a context, is simply an object, and the semantic content of a sentence that contains a complex demonstrative, in a context, is a singular proposition. This theory is defended from various objections to direct reference theories of complex demonstratives, including King's objection from quantification into complex demonstratives.

Naturalistically minded philosophers hope to identify a privileged nonsemantic relation that holds between a mental representation m and that which m represents, a relation whose privileged status underwrites the assignment of reference to m. The naturalist can accomplish this task only if she has in hand a nonsemantic criterion for individuating mental representations: it would be question-begging for the naturalist to characterize m, for the purpose of assigning content, as 'the representation with such and such content'. If we individuate mental representations using the tools of dynamical systems theory, we find that a given mental representation, characterized nonsemantically, emerges in the cognitive system as the result of causal interactions between the subject and her environment. At least for the most basic of our mental representations, I argue that the dynamical systems-based approach to individuation increases the plausibility of a theory that assigns reference as a function of the subject's causal history.

Using a version of situation semantics, this article argues that bare and complex demonstratives are interpreted as individual concepts.

Philosophers who accept tropes generally agree that tropes do play a role in the semantics of natural language, namely as the objects of reference of nominalizations of adjectives, such as 'Socrates’ wisdom' or 'the beauty of the landscape'. In fact, a philosophical discussion of the ontology of tropes can hardly do without the use of such nominalizations. In this paper, I will argue that tropes play a further important role in the semantics of natural language, namely in the semantics of bare demonstratives like 'this' and 'that' in what in linguistics is called identificational sentences.

In this paper, I advance a new view of the semantics of indexicals, using a paper by Quentin Smith as my starting point. I make use of Smith’s examples, refined and expanded upon by myself to argue, as Smith does, that the standard view, that indexicals refer to some prominent features of the context according to an invariant rule called the character, does not agree with a wide range of phenomena. I depart from Smith, however, in denying that we need more complex rules, which he does not give, called metacharacters to account for all the deviations, and instead argue for a view of indexicals as just being special cases of demonstratives. I show how demonstratives can be substituted for indexicals to support this view, and I adduce recent work in the semantics of demonstratives to explain how it can work.

Complex demonstratives, expressions of the form 'That F', 'These Fs', etc., have traditionally been taken to be referring terms. Yet they exhibit many of the features of quantified noun phrases. This has led some philosophers to suggest that demonstrative determiners are a special kind of quantifier, which can be paraphrased using a context sensitive definite description. Both these views contain elements of the truth, though each is mistaken. We advance a novel account of the semantic form of complex demonstratives that shows how to reconcile the view that they function like quantified noun phrases with the view that simple demonstratives function as context sensitive referring terms wherever they occur. If we are right, previous accounts of complex demonstratives have misconceived their semantic role; and philosophers relying on the majority view in employing complex demonstratives in analysis have proceeded on a false assumption.

In this paper, I present a new semantics for demonstratives. Now some may think that David Kaplan (1989a,b) has already given a more than satisfactory semantics for demonstratives, and that there is no need for a new one. But I argue below that Kaplan's theory fails to describe the linguistic meanings of 'that' and other true demonstratives. My argument for this conclusion has nothing to do with cognitive value, belief sentences, or other such contentious matters in semantics and the philosophy of mind. Rather, it appeals to the obvious fact that there can be true utterances of certain sentences containing several occurrences of the same demonstrative (for instance, 'That is taller than that'). My argument can be answered by making a fairly modest revision in Kaplan's theory. But I believe that the resulting revised version of Kaplan's theory ignores or distorts various important semantic features of 'that'. Thus I ultimately argue in favor of a more substantial departure from Kaplan's theory. Perhaps the most remarkable feature of the theory I favor is that it ascribes three distinct sorts of meanings to demonstratives.

Demonstrative noun phrases (e.g., that guy , this ) are of interest to philosophers of language and semanticists because they are sensitive to demonstrations or speaker intentions. The interpretation of a demonstrative therefore sheds light on the role of the context in natural language semantics. This survey reviews two types of approaches to demonstratives: Kaplan's direct reference treatment of demonstratives and other indexicals, and recent challenges to Kaplan's approach that focus on less obviously context-sensitive uses of demonstratives. The survey then covers selected research on demonstratives in linguistics. This research offers new empirical puzzles and contrasting theoretical approaches to demonstratives.

Until recently it was standard to think that all demonstratives are directly referential. This assumption has played important roles in work on perception, reference, mental content, and the nature of propositions. But Jeff King claims that demonstratives with a nominal complement (like ‘that dog’) are quantifiers, largely because there are cases in which the semantic value of such a “complex demonstrative” is not simply an object (2001). Although I agree with King that such cases preclude a directly referential, Kaplanian semantics for complex demonstratives, I will argue that without contentious further assumptions they do not vindicate King’s claim that they are quantifiers. This is because familiar pronouns act like King’s examples of complex demonstratives. Indeed, pronouns and complex demonstratives share behavior that even King overlooks. None of this pronoun behavior shows that pronouns are quantifiers, and similarly none of the analogous demonstrative behavior shows that complex demonstratives are quantifiers.
