He took up the neo-Malthusian position emphatically in his early pamphlet on "Jesus, Shelley, and Malthus," published in 1861, a somewhat youthfully rhetorical, but still a very notable presentment of the three main influences successively brought to bear on the problem of poverty--the spirit of religious submission, the spirit of humanitarian revolt, and the spirit of science. He pleaded for the last. "An acquaintance with political economy," he there declares, "is as necessary to the working man as is a knowledge of navigation to the master of a ship. It is the science of social life, the social science." And he was able in those days of the "orthodox" economics to cite in support of his definition, from the high priest of orthodoxy, a deliverance which may surprise readers whose knowledge of the old economics is not commensurate with their censure of it.
"The object of political economy," says Mr M'Culloch, "is to point out the means by which the industry of man may be rendered most productive of those necessaries, comforts, and enjoyments which constitute wealth; to ascertain the circumstances most favourable for its accumulation, the proportion in which it is divided among the different classes of the community, and the mode in which it may be most advantageously consumed."
And in another early pamphlet on "Poverty and its Effect on the Political Condition of the People," first published in 1863, he put as one of his mottoes, after a more guarded sentence from John Mill, this from Sir James Steuart:--
"The object of political economy is to secure the means of subsistence to all the inhabitants, to obviate every circumstance which might render this precarious, to provide everything necessary for supplying the wants of society, and to employ the inhabitants so as to make their several interests accord with their supplying each other's wants."
But his application of the principle was democratic and Neo-Malthusian, not Collectivist. "Unless," he wrote, "the _necessity_ of the preventative or positive checks to population be perceived; unless it be clearly seen that they must operate in one form if not in another, and that, _though individuals may escape them, the race cannot_, human society is a hopeless and insoluble riddle." And for years before this he had persistently pressed the point in his lectures, steadily defying the odium which his action brought upon him. As early as 1862 we find him temperately replying to denunciation on this head in a lecture on "Malthusianism and its connection with Civil and Religious Liberty," of which a partial report happened to be taken in shorthand. "It may almost seem unwise," he remarked, "to be continually putting this subject before you; but really I find myself so misrepresented, and so liable to be misunderstood, in quarters where one would expect better things, that you must not wonder if I seek to make it clear to you why I persist in this advocacy." He here pressed the law of population as a fundamental datum of political science.
