Perhaps the most radical position is that of Charles Travis, who presents various examples designed to show that the truth of what one says in using a predicate to describe an object is not fixed by the meaning of the predicate, even as a function of specifiable parameters of the occasion of use. See the papers collected in Travis 2008. Responses to the sorts of examples Travis describes vary. One option is to argue that the examples do not involve any variation in truth-value across contexts (see Cappelen & Lepore 2005); another is to argue that, while there is variation in truth-value, it can be understood as a form of indexicality (see Szabo 2001 and Rothschild & Segal 2009). (Sainsbury 2001 argues for a mixture of these two approaches.) A different strategy is to concede that there is variation, but that it is a form of nonindexical context-dependence, which can nevertheless be accommodated within traditional truth conditional semantics (see Predelli 2004, Predelli 2005, MacFarlane 2007, and MacFarlane 2009). |
