The Theory of Moral Sentiments was written by Adam Smith in 1759. It provided the ethical, philosophical, psychological and methodological underpinnings to Smith's later works, including The Wealth of Nations (1776), A Treatise on Public Opulence (1764) (first published in 1937), Essays on Philosophical Subjects (1795), and Lectures on Justice, Police, Revenue, and Arms (1763) (first published in 1896).
