"The Theory of Moral Sentiments" by Adam Smith is a philosophical treatise written in the mid-18th century. The book explores the principles that govern human morality, particularly focusing on how individuals judge the conduct and character of themselves and others. It delves into concepts such as sympathy, propriety of actions, and the moral feelings that arise in social interactions. At the start of the work, Smith introduces the foundational idea that human beings possess inherent principles that make them care about the well-being of others, attributing it to emotions like pity and compassion. He argues that people assess the emotions and actions of others through the lens of their own feelings and experiences. The opening chapters articulate how sympathy operates in understanding both joy and sorrow, laying the groundwork for his detailed analysis of moral sentiments and behaviors throughout the text.
