The Theory of Moral Sentiments

Adam Smith's *The Theory of Moral Sentiments* explores how human morality arises from sympathy—our capacity to share the feelings of others. Through the concept of an impartial spectator, Smith explains how we judge our own and others' actions, balancing self-love with social harmony. The work lays the foundation for understanding virtue, justice, and the corruption of moral sentiments.

Smith begins by establishing sympathy as the bedrock of moral judgment, arguing that we approve or disapprove of others' passions based on our ability to imaginatively share them. He introduces the impartial spectator, an internalized observer whose perspective guides self-evaluation and moral conduct. The book distinguishes between amiable virtues (humanity, kindness) and respectable virtues (self-command, dignity), and emphasizes justice as essential for society's survival, while beneficence is merely ornamental. Smith critiques various moral systems—those based on self-love, reason, and sentiment—and examines how custom and fashion shape moral opinions across cultures. He also explores the corruption of moral sentiments, where wealth and rank are admired over wisdom and virtue, and distinguishes the desire for praiseworthiness from mere praise. Throughout, Smith argues that true virtue lies in achieving propriety—balancing one's emotions to what the impartial spectator can approve—and that self-love, when tempered by sympathy, contributes to social order.
