The publication of The Wealth of Nations in 1776 coincided with America's Declaration of Independence, and with this landmark treatise on political economy, Adam Smith paved the way for modern capitalism, arguing that a truly free market - fired by competition yet guided as if by an 'invisible hand' to ensure justice and equality - was the engine of a fair and productive society. Books I - III of The Wealth of Nations examine the 'division of labor' as the key to economic growth, by ensuring the interdependence of individuals within society. They also cover the origins of money and the importance of wages, profit, rent and stocks, but the real sophistication of his analysis derives from the fact that it encompasses a combination of ethics, philosophy and history to create a vast panorama of society An Inquiry into the Nature and Causes of the Wealth of Nations, generally referred to by its shortened title The Wealth of Nations, is the magnum opus of the Scottish economist and moral philosopher Adam Smith. First published in 1776, the book offers one of the world's first collected descriptions of what builds nations' wealth, and is today a fundamental work in classical economics. By reflecting upon the economics at the beginning of the Industrial Revolution, the book touches upon such broad topics as the division of labour, productivity, and free markets. (Wikipedia)
