In his study of the perfectibility of man and the prospect of a future reign of general justice and benevolence, Godwin was even more visionary than Condorcet, as in his political views he was more radical than the Revolutionists. Condorcet had at least sought to connect his picture of the future with a reasoned survey of the past, and to find a chain of connection, but the perfectibility of Godwin hung in the air, supported only by an abstract theory of the nature of man. It can hardly be said that he contributed anything to the theoretical problem of civilisation. His significance is that he proclaimed in England at an opportune moment, and in a more impressive and startling way than a sober apostle like Priestley, the creed of progress taught by French philosophers, though considerably modified by his own anarchical opinions. 5. Perfectibility, as expounded by Condorcet and Godwin, encountered a drastic criticism from Malthus, whose Essay on the Principle of Population appeared in its first form anonymously in 1798. Condorcet had foreseen an objection which might be raised as fatal to the realisation of his future state. Will not the progress of industry and happiness cause a steady increase in population, and must not the time come when the number of the inhabitants of the globe will surpass their means of subsistence? Condorcet did not grapple with this question. He contented himself with saying that such a period must be very far away, and that by then "the human race will have achieved improvements of which we can now scarcely form an idea." Similarly Godwin, in his fancy picture of the future happiness of mankind, notices the difficulty and shirks it. "Three-fourths of the habitable globe are now uncultivated. The parts already cultivated are capable of immeasurable improvement. Myriads of centuries of still increasing population may pass away and the earth be still found sufficient for the subsistence of its inhabitants." Malthus argued that these writers laboured under an illusion as to the actual relations between population and the means of subsistence. In present conditions the numbers of the race are only kept from increasing far beyond the means of subsistence by vice, misery, and the fear of misery. [Footnote: This observation had been made (as Hazlitt pointed out) before Malthus by Robert Wallace (see A Dissertation on the Numbers of Mankind, p. 13, 1753). It was another book of Wallace that suggested the difficulty to Godwin.] In the conditions imagined by Condorcet and Godwin these checks are removed, and consequently the population would increase with great rapidity, doubling itself at least in twenty-five years. But the products of the earth increase only in an arithmetical progression, and in fifty years the food supply would be too small for the demand. Thus the oscillation between numbers and food supply would recur, and the happiness of the species would come to an end.
