More remarks on this and that

Lynsey Wolter (U. California, Santa Cruz)

 

This is a talk about the distribution and interpretation of demonstrative descriptions (e.g. that cat, this dog) and definite descriptions (e.g. the bird, the highest mountain in California).

 

Demonstrative and definite descriptions both require that there be a uniquely identifiable referent satisfying the descriptive content. Thus, in (1), a context in which there is no uniquely identifiable cat, neither kind of description is acceptable.

There were three cats in the room. *The/*That/*This cat meowed.

 

But there are also striking differences between definite and demonstrative descriptions. For example, demonstrative descriptions are sensitive to speaker demonstrations, while definite descriptions are not, as illustrated in (2). Definite descriptions, on the other hand, are compatible with content that necessarily denotes a singleton set, while demonstrative descriptions are not, except with a special emotive reading, as shown in (3). Differences such as these have led some researchers to conclude that the referents of demonstrative and definite descriptions are identified in fundamentally different ways.

In this talk, I will propose an analysis in which definite and demonstrative descriptions are not as dissimilar as the contrasts in (2–3) might suggest. I will argue that definite and demonstrative determiners require uniqueness relative to a contextually restricted domain, and that demonstrative determiners place constraints on how domain restriction takes place. The analysis, while implemented in a formal framework, makes room for insights from both formal and functional approaches, resulting in greater empirical coverage than previous approaches have achieved. More broadly, the analysis has implications for the semantics-pragmatics interface, suggesting that the lexical semantics of determiners is tightly interwoven with pragmatic factors.
