Fogelin, R.J. - Routledge Philosophy GuideBook to Berkeley and the Principles of Human Knowledge

George Berkeley (1685–1753) was born and educated in Ireland. At the age of twenty-four he began a remarkable period in which he published his Essay towards a New Theory of Vision (1709) and then the two works on which his philosophical reputation rests: A Treatise Concerning the Principles of Human Knowledge (1710), and Three Dialogues between Hylas and Philonous (1713). He also published a book on physical theory, De Motu (1721), a work that illustrates his lifelong interest in scientific issues.
