The Scottish philosopher and historian David Hume (17111776) has often been regarded as a key Enlightenment thinker. However, his image has been long contested between those who consider him a conservative and those who see him as a key liberal thinker. Hume's Sceptical Enlightenment offers a new interpretation for such diverse images and demonstrates the uniqueness of Hume as an Enlightenment thinker, illustrating how his 'spirit of scepticism' often leads him into seemingly paradoxical positions. This book will be of interest to Hume scholars, intellectual historians of 17th- to 19th-century Europe and those interested in the Enlightenment more widely.
