Refuting these Franco-American ideas, Alexander Hamilton, the secretary of the American Treasury, in 1791 sent Congress his
If Adam Smith was delighted by the new era, arguing that the division of labour and free trade would change the sinful world for the better, Robert Malthus condemned it on behalf of his science. The laws of human nature cannot be changed. The first law is that man must eat. The second is that he has a passion for reproducing. Neither law was new – it was Malthus’s discovery of their incompatibility that was shocking. If there is enough food for everyone, the population will double in twenty-five years, as it did in the American colonies. For this, land must be infinitely available. When there is a limit on land, the growth of the population will always outpace the growth of the productivity of labour.
John Maynard Keynes called Malthus’s
Malthus’s dispute with William Godwin and Adam Smith was based on their different understanding of economic value, but behind this lay a difference in the way they understood people. Smith wrote about the wealth of nations, by which he meant not peoples but states. In contrast, Malthus understood the population as a multitude – a certain number of individuals, rich or poor, carrying out trade and reproducing. In his interest in population statistics, Malthus was ahead of Smith and many nineteenth-century economists. Godwin was a Calvinist minister, Malthus an Anglican priest, and Smith a Presbyterian layman. All three critically observed the British Empire colonising overseas territories which, in some cases, left the empire. While Godwin later switched to book publishing, the other two had careers directly connected to imperial policies: Smith had a lucrative post on the Scottish Customs Committee, while Malthus became a professor of history and political economy at the East India Company College. Neither Smith nor Malthus visited the overseas colonies, but both men knew adjacent colonial possessions very well. For Smith this was his native Scotland, for Malthus Ireland, a subject of scholarly interest. And, for both of them, distant America was an intriguing example of the new imperial economy. Wars were fought over colonies, garrisons were quartered there, flotillas sailed for their sake. Why was all this done? What could justify the expense? From Smith to Bentham and his Manchester followers, liberalism was the critical theory of empire.
