This is the first comprehensive biography of John Locke to be published in nearly a half century. Setting Locke’s life within exciting historical and intellectual contexts, which included the English Civil War, religious persecution, and the Glorious Revolution of 1688, Roger Woolhouse interweaves an account of Locke’s life with a summary and development of his ideas in theory of knowledge, philosophy of science, medicine, economics, philosophy of religion, and political philosophy. Systematic and encyclopedic in its coverage, Woolhouse’s biography offers both an account and explanation of Locke’s ideas, while treating seriously his emotional relationship with Elinor Parry. Based on broad research and many years of study of Locke’s philosophy, this volume is an authoritative biography on one of the most significant early modern philosophers.
