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.
