This companion to the study of one of the great works of Western philosophy--David Hume's Enquiry concerning Human Understanding (1748)--provides a general overview of the Enquiry, especially for those approaching it for the first time, and sets it in the context of Hume's philosophical work as a whole. It elucidates, analyzes, and assesses the philosophy of the Enquiry, clarifying its interpretation and discussing recent developments in Hume scholarship that are relevant to the Enquiry. The eminent contributors to this volume cover a broad range of topics: meaning, induction, skepticism, belief, personal identity, causation, freedom, miracles, probability, and religious belief.
