Adam Smith (1723-1790) was a towering figure in the field of economics and moral philosophy. Born in Kirkcaldy, Scotland, Smith's intellectual contributions laid the foundations for classical economics. His seminal work, 'An Inquiry into the Nature and Causes of the Wealth of Nations' (1776), often simply referred to as 'The Wealth of Nations,' advocates for free market economics and presents his theory of the invisible hand, which suggests that an individual's self-interest tends to promote the good of the community. Smith's treatise is widely considered the first modern work of economics and remains a core text in the study of economic theory. As a key proponent of the Scottish Enlightenment, Smith's literary style combined empirical observation with clear, logical argumentation, which was aimed at understanding the nature of wealth creation and the principles that contribute to the prosperity of nations. Prior to 'The Wealth of Nations,' Smith authored 'The Theory of Moral Sentiments' (1759), where he explored the ethical underpinnings of human behavior. His work in this treatise set the stage for his later economic theories by emphasizing the role of sympathy in human interactions. Smith's legacy endures primarily through his comprehensive analysis of how economies function and the mechanisms by which wealth is produced and distributed, thereby influencing generations of economists, philosophers, and policy-makers.
