Capitalism in flames, populism and nationalism on the march across Europe, a US president bent on demolishing free trade, a British shadow chancellor calling openly for the overthrow of capitalism itself . . . the 21st century is not going to script.

More than any other, the Scottish political economist and philosopher Adam Smith stands at the centre of this ideological battlefield, while around him clash competing views of economics, markets and societies.
