This volume provides an authoritative edition of Dewey’s The Quest for Cer­tainty: A Study of the Relation Between Knowledge and Action. The book is made up of the Gifford Lectures deliv­ered April–May 1929 at the University of Edinburgh. Writing to Sidney Hook, Dewey described this work as “a criti­cism of philosophy as attempting to at­tain theoretical certainty.” In the Philo­sophical Review Max C. Otto later elaborated: “Mr. Dewey wanted, so far as lay in his power, to crumble into dust, once and for all, ‘the chief fortress of the classic philosophical tradition.”
