'A Treatise of Human Nature' (1739-40), David Hume’s comprehensive attempt to base philosophy on a new, observationally grounded study of human nature, is one of the most important texts in Western philosophy. It is the focal point of current attempts to understand 18th-century western philosophy. The Treatise addresses many of the most fundamental philosophical issues; causation, existence, freedom and necessity, and morality. This is the only abridge edition of Hume's classic philosophy text. A clear presentation, with wide margins for practical use by students including an extended Introduction, chronology of Hume's life and times, glossary, suggestions for further reading, a selection of critical responses and textual notes.
