Abstract
Perhaps one of the most underappreciated philosophical movements is British Idealism. This movement arose during the latter half of the nineteenth century and began to wane after the outbreak of the First World War. British Idealism has produced a number of important figures, such as Bernard Bosanquet, R. G. Collingwood, F. H. Bradley and T. H. Green, as well as other important, but less well known, figures, such as J. S. Mackenzie, John Henry Muirhead and James Seth. It has also given us a number of lasting philosophical ideas.
