Adam Smith and Immanuel Kant: On Markets, Duties, and Moral Sentiments

Abstract

This note points out a neglected parallel between the philosophies of Adam Smith and Immanuel Kant related to their views on self-interest, morality, and society. First, I explain the distinction between Kant’s perfect and imperfect duties, and how they result from his moral philosophy. Next, I summarize Smith’s two major perspectives on human behavior, as presented in The Theory of Moral Sentiments and The Wealth of Nations, and discuss the apparent conflict between them. Finally, I use Kant’s two types of duties, along with his concept of the kingdom of ends, to explicate my interpretation of the relationship between Smith’s two strains of thought. By explaining these dual aspects of Kant’s ethical system in relation to Smith, I hope to give a new perspective on the apparent duality in Smith’s thought, as well as help bring out the oft-neglected social aspects of Kant’s.
