Stefano Predelli comes to the defense of the traditional "formal" approach to natural-language semantics, arguing that it has been misrepresented not only by its critics, but also by its foremost defenders. In Contexts he offers a fundamental reappraisal, with particular attention to the treatment of indexicality and other forms of contextual dependence which have been the focus of much recent controversy. In the process, he presents original approaches to a number of important semantic issues, including the relationship between validity and indexicality, the limits of token-reflexive systems, the significance of contextualist arguments, and the interpretation of attitude reports. Contexts will make invigorating reading for all philosophers of language and many linguists.

• What’s essential to Newcomb’s problem? 1. You must choose between two particular acts: A1 = you take just the opaque box; A2 = you take both boxes, where the two states of nature are: S 1 = there’s $1M in the opaque box, S2 = there’s $0 in the opaque box.

Specificity has been defined in the linguistic literature according to two different criteria: one corresponding to Quine's opaque and transparent contexts, and the other to criteria closely related to Donellan's referential/attributive distinction. The paper argues that only the former definition is a semantic one since it alone manifests linguistic correlates. The meaning changes involving referential/attributive factors are pragmatic in nature. In the concluding section is is argued that the semantics of specificity is completely independent of the relative scope interpretation of an indefinite noun phrase in relation to other quantified nouns in the sentence. This is demonstrated using sentences which contain an indefinite interacting with both an opaque operator and a second quantifier. It is shown that such sentences can be four ways ambiguous.
