Few works of economic and political analysis have exerted a more profound influence on European, American and latterly world economic and social policy than Adam Smith's Wealth of Nations. The version of Adam Smith's economic and social philosophy which has been invoked by proponents such as those in the Adam Smith Institute has often not been the product of a reading of the whole of the Wealth of Nations, but has rested instead on acceptance of the selective reading of parts of the book developed by nineteenth-century market liberals. In the nineteenth century, critiques of the effects of the division of labour were developed outside political economy by a sequence of British cultural critics from Hazlitt and Coleridge to Carlyle and Arnold, who deployed them in their attacks on contemporary industrial capitalism and the 'dismal science' of economics which they saw as providing its intellectual rationalisation; more radically, they formed an important element in the critique of political economy developed by Engels and Marx.
