This book provides a study of the forces underlying the development of economic thought at
Cambridge University during the late nineteenth century and the first half of the twentieth
century. The primary lens it uses to do so is an examination of how Arthur Cecil Pigou's
thinking heavily influenced by his predecessor Alfred Marshall evolved. Aspects of Pigou's
context biography and philosophical grounding are reconstructed and then situated within the
framework of Ludwik Fleck's philosophy of scientific knowledge most notably by drawing on the
notions of 'thought styles' and 'thought collectives'. In this way Knight provides a novel
contribution to the history of Pigou's economic thought.
