"For Smith’s encyclopedic scope and knowledge there can be only admiration. It was only in the eighteenth century that so huge, all-embracing, secure, caustic, and profound a book could have been written. Indeed, The Wealth of Nations and The Theory of Moral Sentiments, together with his few other essays, reveal that Smith was much more than just an economist. He was a philosopher-psychologist-historian-sociologist who conceived a vision that included human motives and historic “stages” and economic mechanisms, all of which expressed the plan of the Great Architect of Nature (as Smith called him). From this viewpoint, The Wealth of Nations is more than a masterwork of political economy. It is part of a huge conception of the human adventure itself."
