Most philosophers recognize that applying the standard semantics for complex demonstratives to non-deictic instances results in truth conditions that are anomalous, at best. This fact has generated little concern, however, since most philosophers treat non-deictic demonstratives as marginal cases, and believe that they should be analyzed using a distinct semantic mechanism. In this paper, I argue that non-deictic demonstratives cannot be written off; they are widespread in English and foreign languages, and must be treated using the same semantic machinery that (...) is applied to deictic instances.

Standard semantic theories predict that non-deictic readings for complex demonstratives should be much more widely available than they in fact are. If such readings are the result of a lexical ambiguity, as Kaplan (1977) and others suggest, we should expect them to be available wherever a definite description can be used. The same prediction follows from ‘hidden argument’ theories like the ones described by King (2001) and Elbourne (2005). Wolter (2006), however, has shown that complex demonstratives admit non-deictic interpretations only (...) when a precise set of structural constrains are met. In this paper, I argue that Wolter’s results, properly understood, upend the philosophical status quo. They fatally undermine the ambiguity theory and demand a fundamental rethinking of the hidden argument approach. (shrink)

Viebahn (2018) has recently argued that several tests for ambiguity, such as the conjunction-reduction test, are not reliable as tests for polysemy, but only as tests for homonymy. I look at the more fine-grained distinction between regular and irregular polysemy and I argue for a more nuanced conclusion: the tests under discussion provide systematic evidence for homonymy and irregular polysemy but need to be used with more care to test for regular polysemy. I put this conclusion at work in the (...) context of the debate over the alleged referential-attributive ambiguity of the definite article. In reply to various criticisms, defenders of the ambiguity view argue that this is a case of polysemy. But opponents object that the dual use of the definite article fails tests for ambiguity. The debate seems to have come to stalemate, unless the relevance of the tests is determined for cases of alleged polysemy. I conclude that the balance of considerations incline towards rejecting the ambiguity thesis. (shrink)

Some expressions of English, like the demonstratives ‘this’ and ‘that’, are referentially promiscuous: distinct free occurrences of them in the same sentence can differ in content relative to the same context. One lesson of referentially promiscuous expressions is that basic logical properties like validity and logical truth obtain or fail to obtain only relative to a context. This approach to logic can be developed in just as rigorous a manner as David Kaplan’s classic logic of demonstratives. The result is a (...) logic that applies to arguments in English containing multiple occurrences of referentially promiscuous expressions. (shrink)
