John Elliot Cairnes (1823-1875) was an ardent disciple of John Stuart Mill, and is often regarded as ‘the last of the Classical economists’. He wrote what was the definitive statement of the methodology of the classical school in The Character and Logical Method of Political Economy (1875) and defended Classical Ricardian doctrine throughout his life. This six-volume set contains virtually all of the published work of Cairnes; it brings together, for the first time, all of his major works and almost all of his uncollected articles, pamphlets, and published letters. It is an essential resource for those studying the man himself, the tradition of Classical economy, and Irish intellectual history in the nineteenth century. The set includes a new introduction contextualizing Cairnes’s life and work and exploring the evolving reception of his ideas.
