Wittgenstein’s ‘therapeutic’ conception of philosophy: as a challenge to standard understandings of what knowledge must be

I am speaking on #Wittgenstein this coming Wednesday, at the Institute of Education, in London (Bedford Street), at 5.30. Maybe see you there.
 In this talk, I will explore the way in which a Wittgensteinian ‘therapeutic’ (liberatory) vision of philosophy changes radically our understanding of what kind of knowledge, if any, a philosopher has, what kind of ‘expertise’ she has. But this is not even a matter of interest narrowly to philosophers. If affects every discipline which, as Winch would have it, shares or inherits any of philosophy’s character. Examples include education, economics, and ‘social science’ in general.
