Adam Smith, born in Kirkcaldy, Scotland, in 1723, is celebrated as the "father of modern economics" and a key figure of the Scottish Enlightenment. His seminal work, "An Inquiry into the Nature and Causes of the Wealth of Nations," published in 1776, revolutionized economic thought by introducing the concept of absolute advantage and advocating for free trade and limited government intervention in markets. Smith's ideas laid the foundation for classical liberalism and free-market economics, making him an enduring influence in the field. Beyond his economic theories, Smith's work "The Theory of Moral Sentiments" explores the moral and ethical dimensions of human behavior, showcasing his deep philosophical insights. His legacy continues to shape contemporary economic theory and policy, making him a towering figure in the history of economic thought.
