 Part VI of TMS, added in the last edition, presents the virtues of prudence, benevolence and self-command by way of a series of elegant character portraits, and part VII offers a short history of moral philosophy, which stresses the contributions of Plato, Aristotle, and the Stoics. This way of concluding the book reinforces the emphasis on virtuous character, as opposed to a decision-procedure for specific actions, and indicates that we might gain by returning to the ancient schools of moral philosophy that shared this emphasis. Smith does not endorse any ancient moral theorist uncritically, but—like Shaftesbury and Hume—he seems to look forward to a revival of ancient Greek ethics, a modern retrieval and re-working of the character ideals on which those schools had focused.
