How to do Philosophy

Why should the philosophical achievement of Ludwig Wittgenstein be taken seriously in the twenty-first century? This text answers this question by elaborating the distinctive therapeutic conception of philosophy defended in Wittgenstein’s later work, typified by Philosophical Investigations. Here, Wittgenstein’s highly contextual, problem-specific and person-specific conception of the philosophical project is clarified with reference to his own writings. In so doing, this text challenges contemporary failures to properly acknowledge all publications from those writings as posthumous, Nachlass (Legacy), or to treat judiciously the material published from that Legacy. Explicitly following Gordon Baker’s last essays (Wittgenstein’s Method: Neglected Aspects, 2004), and drawing on biographical sources as well as scholarly ones, the text addresses Wittgenstein’s published oeuvre. Importantly, this exposition gives weight to the Big Typescript (2005) and Voices of Wittgenstein (2003), as two “projected works” attempting to present Wittgenstein’s philosophical agenda. Further, Wittgenstein’s very last writings are argued here to constitute a single, broadly unified project, rebutting the suggestion of a “third Wittgenstein”. Moreover, the book sketches philosophical discussions conducted in line with Wittgenstein’s own conception of philosophy’s project to continue chains of examples of the kind he used in exposition of it.
