Vagueness
Advisory Editor: Timothy Williamson, Edinburgh
The sorites paradox raises the philosophical problem of vagueness in its most intractable form. If the successive removal of grains turns a heap into a non-heap, standard reasoning seems to show that at some point the removal of one grain turned a heap into a non-heap, a conclusion which many dislike. One can label the problem by saying that the vagueness of the distinction between heaps and non-heaps is to blame. Many accounts treat vagueness as a semantic or pragmatic phenomenon; others treat it as epistemic or ontological. The paradox cannot be solved by means of a technical fix; what is needed is a philosophically well-motivated account of the underlying nature of vagueness. Such an account may engage with wider issues about deviance in logic, disquotational and verificationist theories of truth, and the idea that reality itself is indeterminate. Historical discussion, for example of the sorites paradox in antiquity or of the emergence of vagueness as a problem in early analytic philosophy, is also relevant. Contributors will include Stephen Schiffer and Roy Sorensen.
