Justus Buchler and the Community of Query

Before he originated the field of philosophy for children, Matthew Lipman spent nearly twenty years teaching at Columbia University and its affiliated colleges under the tutelage of the American philosopher Justus Buchler. In those years Lipman’s scholarship focused on Buchler’s naturalist metaphysics, which was informed by Buchler’s scholarship on the philosophy of Charles Peirce. In this essay I relate Lipman’s relationship with Buchler, summarise Buchler’s theory of human judgement, and indicate key parts of that theory that influenced Lipman’s own theory of judgement and multidimensional thinking. I then discuss the pedagogical turn Buchler made with his theory, including his conception of classroom discussion as a mode of ‘community of query,’ which became the prototype for Lipman and Ann Margaret Sharp’s theory of ‘community of inquiry’ as a protocol of classroom dialogue and a paradigm of philosophical practice and democratic decision-making.
