Reprinted from the original edition in three volumes and edited, with an analytical index, by L. A. Selby-Bigge. Revised by P. H. Nidditch.
David Hume's Treatise of Human Nature, composed before the author was twenty-eight years old, was published in 1739 and 1740. In revising the late L.A. Selby-Bigge's edition of Hume's Treatise Professor Nidditch corrected verbal errors and took account of Hume's manuscript amendments. He also supplied the text of the Abstract of the Treatise following the original 1740 edition and provided an apparatus of variant readings.
More up-to-date both on general and on political philosophy than anything else I know ... be careful to buy an edition such as the Oxford one which contains at the end the Abstract, which is Hume's own summary and simplification of his main ideas.
