Due to his theory of 'immaterialism' and Schopenhauer's regard of him as the 'father of idealism', George Berkeley (1685-1753) is one of the most important thinkers of the Early Modern period. The Bloomsbury Companion to Berkeley is a comprehensive one volume reference guide to his life, thought and work. In twenty six original essays, a team of leading international scholars of Modern Philosophy cover all of Berkeley's writings including unpublished manuscripts and correspondence, thus providing readers with a complete and accessible source of information to the entire corpus of Berkeley's writings. The book includes extended essays on key themes in Berkeley's thought as well as sections covering Berkeley's life and times, and also his intellectual influence and legacy.
