Description: Minutes of the Moral Sciences Club meeting in the Gibbs building, King's College, Cambridge in October 1946, when Wittgenstein and Popper famously clashed over the nature of philosophy. Wittgenstein reportedly waved a hot poker at Popper before leaving the meeting in a huff. The minutes are dated October 26, a Saturday (the usual date of meetings), but John Eidinow and David Edmonds write that meetings had been moved to Fridays, or this one had, to avoid clashing with the weekly meeting of the Cambridge Apostles, which Wittgenstein also attended.
