The Oxford Philosophical Texts series consists of truly practical and accessible guides to major philosophical texts in the history of philosophy from the ancient world up to modern times. Each book opens with a comprehensive introduction by a leading specialist which covers the philosopher's life, work, and influence. Endnotes, a full bibliography, guides to further reading, and an index are also included. The series aims to build a definitive corpus of key texts in the Western philosophical tradition, forming a reliable and enduring resource for students and teachers alike. Now one of the most widely read works in philosophy, David Hume's An Enquiry concerning Human Understanding (1748) introduced his philosophy to a broad educated readership. In it he gives an elegant an accessible presentation of strikingly original and challenging views about the limited powers of human understanding, the attractions of skepticism, the compatibility of free will and determinism, and weaknesses in the foundations of religion. In this volume, an authoritative new version of the text is enhanced by detailed explanatory notes, a glossary of terms, a full list of references, and a section of supplementary readings.
