Adam Smith, on the other hand, was determined to overturn the conventional wisdom of his day. Above all, he objected to the notion that money was a creation of government. In this, Smith was the intellectual heir of the Liberal tradition of philosophers like John Locke, who had argued that government begins in the need to protect private property and operated best when it tried to limit itself to that function. Smith expanded on the argument, insisting that property, money, and markets not only existed before political institutions but were the very foundation of human society.
