Â‘It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interestâ€™ With this landmark treatise on political economy, Adam Smith paved the way for modern capitalism, arguing that a truly free market Â– fired by competition yet guided as if by an Â‘invisible handâ€™ to ensure justice and equalityÂ Â– was the engine of a fair and productive society. Books IÂ–III of theÂ Wealth of Nationsexamine the Â‘division of labourâ€™ as the key to economic growth, by ensuring the interdependence of individuals within society. They also cover the origins of money, the importance of wages, profit, rent and stocks. Smithâ€™s work laid the foundations of economic theory in general and Â‘classicalâ€™ economics in particular, but the real sophistication of his analysis derives from the fact that it also encompasses a combination of ethics, philosophy and history to create a vast panorama of society. This edition contains an analytical introduction offering an in-depth discussion of Smith as an economist and social scientist, as well as a preface, further reading and explanatory notes. The Wealth of Nations Books IV-VÂ are also published in Penguin Classics.
