The Theory of Moral Sentiments [1759]

Adam Smith, 2 vols. (D. D. Raphael and A. L. Macfie, eds., Liberty Fund, 1982)

In this classic text, the founder of modern capitalism discusses the psychological basis of morality.  He continues the tradition begun by Hobbes by discussing morality in terms of man’s natural freedom and the primacy of self-interest.
