Abstract
The Theory of Moral Sentiments is Adam Smith's major contribution to ethical thought. Although it underwent six revisions during his lifetime, its primary arguments did not change, and this chapter focuses on those aspects that remain constant, beginning with an overview of Smith's theory followed by a discussion of the main elements of the theory. Smith presents morality as systems of overlapping spontaneous order that arise unintentionally based on continuous interactions, reactions, and responses to feedback. Although the philosopher can discover the relative utility of specific aspects of a community's moral standards, and thus make recommendations or encouragements to increase utility, Smith agrees with Hume that moral distinctions are not derived from reason.
