who propounded the theory of division of labour
Division of labour In Plato's Republic, the origin of the state lies in the natural inequality of humanity, which is embodied in the division of labour.
Jean-Jacques Rousseau The Social Contract outlines the basis for a legitimate political order within a framework of classical republicanism. Published in 1762, it became one of the most influential works of political philosophy in the Western tradition. It developed some of the ideas mentioned in an earlier work, the article Économie Politique (Discourse on Political Economy), featured in Diderot's Encyclopédie. The treatise begins with the dramatic opening lines, "Man is born free, and everywhere he is in chains. Those who think themselves the masters of others are indeed greater slaves than they."
