The definitions in the Definitions in political economy occupy very few of the book’s pages. It is difficult perhaps to gauge the readership for which Malthus intended the work: the definitions themselves might have been intended for the boys in his classes at Haileybury, setting out basic concepts in a clear and precise manner, but most of the work is taken up with a discussion of the use and more particularly the misuse of various of those basic terms by other writers in political economy – the French economists, Adam Smith, David Ricardo, James Mill and J. R. McCulloch. Much would have been familiar from arguments in his earlier works on political economy, although with a number of these he was taking on adversaries who had published more recently.
