"As Robert Heilbroner has so aptly observed, economics has produced "a handful of men" whose contributions to mankind have been "more decisive for history than many acts of statesman who basked in brighter glory, often more profoundly disturbing then the shuttling of armies back and forth across frontiers, and more powerful for good and bad than the edicts of kings and legislatures." One such person cited by Heilbroner is Thomas Robert Malthus."
