John Wisdom’s lectures were never published and though his papers are held at Trinity College Library, Cambridge (Wisdom/WSDM), the archive is, for the most part, a series of fragments. While there are some incomplete manuscripts, nothing resembling the Gifford Lectures could be found. That said, discussions of the lectures can be found in Renford Bambrough, Truth and God (London: Methuen, 1969); and Stephen E. Toumlin, The Uses of Argument (Cambridge: Cambridge University Press, 1958).
