Thomas Reid (1710-96) is increasingly being seen as a highly significant philosopher and a central figure in the Scottish Enlightenment. This edition of Reid's classic philosophical text in the philosophy of mind at long last gives scholars a complete critically edited text of the Inquiry. The critical text is based on the fourth life-time edition (1785). A selection of related documents showing the development of Reid's thought, textual notes, bibliographical details of previous editions, and a full introduction by the editor makes this an important contribution to the study of this increasingly respected philosopher. Key Features: *Complete, critically edited text of the Inquiry accompanied by a judicious selection of manuscript evidence relating to its composition. *Comprehensive Introduction providing an historical and philosophical account of the formation of the Inquiry. *Detailed textual notes which include bibliographical details and allusions, translations, references to secondary literature and selected passages from Reid's MSS.
