Abstract

Wittgenstein has been likened to a Pyrrhonian sceptic, one who employs dialectical skills to avoid rather than defend doctrine, but it is his role in exposing and excavating the sands upon which modern scepticisms have been built that is the subject of this new volume of largely original essays. The first three chapters, by Crispin Wright, Akeel Bilgrami and Michael Williams find inspiration in On Certainty for singling out key moves in the initial set-up of external world scepticism; the next four chapters, by James Conant, Denis McManus, Ilham Dilman and Jane Heal involve discussions of external world (Cartesian) scepticism, semantic (Kantian) scepticism, scepticism about language (linguistic idealism) and the factuality of the mental that are either commentaries on, or discussions inspired by, Wittgenstein’s writings. The last five chapters focus on Stanley Cavell’s important and under-appreciated work on other minds scepticism—a form of scepticism that, on Cavell’s reading, is never far from the surface of Philosophical Investigations. Responses to modern scepticisms can be broadly divided into two categories: (1) Problem- Accepting Responses: those that regard the sceptical problem as legitimate and seek an answer that takes the form of an appropriate justification for (what the sceptic characterizes as) our ordinary knowledge or beliefs; and (2) Problem-Rejecting Reponses: those that regard the sceptical ‘problem’ as illegitimate (and so, not requiring an answer) because of hidden and contestable theoretical commitments or because it subtly transgresses conditions of sensemaking. This is a volume devoted entirely to the second of these categories, responses that are directed to, as McManus puts it, “a layer in which our philosophical questions are constituted”(p.
