Recent decades have seen a remarkable growth of interest in intellectual history. Intellectual history has become a popular branch of historical studies at the same time as it has a growing audience among students reading politics, philosophy, international relations, English, and other academic areas across the arts and social sciences. This new landmark collection from Routledge provides a comprehensive survey of the subdiscipline, and assembles the very best research undertaken by scholars in Britain, Europe, North America, and the wider world from ancient times to the present. The collection offers an essential synthesis of past and current work but pays special attention to prevailing controversies in order to provide readers with an up-to-date sense of the area.
