it stands in the world of thought as an accepted truth, which compels the recognition even of those who would fain disbelieve it.
The causes of its triumph, the sources of its strength, are not obscure. Seemingly backed by an indisputable arithmetical truth—that a continuously increasing population must eventually exceed the capacity of the earth to furnish food or even standing room, the Malthusian theory is supported by analogies in the animal and vegetable kingdoms, where life everywhere beats wastefully against the barriers that hold its different species in check—analogies to which the course of modern thought, in leveling distinctions between different forms of life, has given a greater and greater weight; and it is apparently corroborated by many obvious facts, such as the prevalence of poverty, vice, and misery amid dense populations; the general effect of material progress in increasing population without relieving pauperism; the rapid growth of numbers in newly settled countries and the evident retardation of increase in more densely settled countries by the mortality among the class condemned to want.
The Malthusian theory furnishes a general principle which accounts for these and similar facts, and accounts for them in a way which harmonizes with the doctrine that wages are drawn from capital, and with all the principles that are deduced from it. According to the current doctrine of wages, wages fall as increase in the number of laborers necessitates a more minute division of capital; according to the Malthusian theory, poverty appears as increase in population necessitates the more minute division of subsistence. It requires but the identification of capital with subsistence, and number of laborers with population, an identification made in the current treatises on political economy, where the terms are often converted, to make the two propositions as identical formally as they are substantially. Ref. 015 And thus it is, as stated by Buckle in the passage previously quoted, that the theory of population advanced by Malthus has appeared to prove decisively the theory of wages advanced by Smith.
Ricardo, who a few years subsequent to the publication of the ”Essay on Population“ corrected the mistake into which Smith had fallen as to the nature and cause of rent, furnished the Malthusian theory an additional support by calling attention to the fact that rent would increase as the necessities of increasing population forced cultivation to less and less productive lands, or to less and less productive points on the same lands, thus explaining the rise of rent. In this way was formed a triple combination, by which the Malthusian theory has been buttressed on both sides—the previously received doctrine of wages and the subsequently received doctrine of rent exhibiting in this view but special examples of the operation of the general principle to which the name of Malthus has been attached—the fall in wages and the rise in rents which come with increasing population being but modes in which the pressure of population upon subsistence shows itself.
Thus taking its place in the very framework of political economy (for the science as currently accepted has undergone no material change or improvement since the time of Ricardo, though in some minor points it has been cleared and illustrated), the Malthusian theory, though repugnant to sentiments before alluded to, is not repugnant to other ideas which, in older countries at least, generally prevail among the working classes; but, on the contrary, like the theory of wages by which it is supported and in turn supports, it harmonizes with them. To the mechanic or operative the cause of low wages and of the inability to get employment is obviously the competition caused by the pressure of numbers, and in the squalid abodes of poverty what seems clearer than that there are too many people?
But the great cause of the triumph of this theory is, that, instead of menacing any vested right or antagonizing any powerful interest, it is eminently soothing and reassuring to the classes who, wielding the power of wealth, largely dominate thought. At a time when old supports were falling away, it came to the rescue of the special privileges by which a few monopolize so much of the good things of this world, proclaiming a natural cause for the want and misery which, if attributed to political institutions, must condemn every government under which they exist. The ”Essay on Population“ was avowedly a reply to William Godwin’s ”Inquiry concerning Political justice,“ a work asserting the principle of human equality; and its purpose was to justify existing inequality by shifting the responsibility for it from human institutions to the laws of the Creator. There was nothing new in this, for Wallace, nearly forty years before, had brought forward the danger of excessive multiplication as the answer to the demands of justice for an equal distribution of wealth; but the circumstances of the times were such as to make the same idea, when brought forward by Malthus, peculiarly grateful to a powerful class, in whom an intense fear of any questioning of the existing state of things had been generated by the outburst of the French Revolution.
Now, as then, the Malthusian doctrine parries the demand for reform, and shelters selfishness from question and from conscience by the interposition of an inevitable necessity. It furnishes a philosophy by which Dives as he feasts can shut out the image of Lazarus who faints with hunger at his door; by which wealth may complacently button up its pocket when poverty asks an alms, and the rich Christian bend on Sundays in a nicely upholstered pew to implore the good gifts of the All Father without any feeling of responsibility for the squalid misery that is festering but a square away. For poverty, want, and starvation are by this theory not chargeable either to individual greed or to social maladjustments; they are the inevitable results of universal laws, with which, if it were not impious, it were as hopeless to quarrel as with the law of gravitation. In this view, he who in the midst of want has accumulated wealth, has but fenced in a little oasis from the driving sand which else would have overwhelmed it. He has gained for himself, but has hurt nobody. And even if the rich were literally to obey the injunctions of Christ and divide their wealth among the poor, nothing would be gained. Population would be increased, only to press again upon the limits of subsistence or capital, and the equality that would be produced would be but the equality of common misery. And thus reforms which would interfere with the interests of any powerful class are discouraged as hopeless. As the moral law forbids any forestalling of the methods by which the natural law gets rid of surplus population and thus holds in check a tendency to increase potent enough to pack the surface of the globe with human beings as sardines are packed in a box, nothing can really be done, either by individual or by combined effort, to extirpate poverty, save to trust to the efficacy of education and preach the necessity of prudence.
A theory that, falling in with the habits of thought of the poorer classes, thus justifies the greed of the rich and the selfishness of the powerful, will spread quickly and strike its roots deep. This has been the case with the theory advanced by Malthus.
And of late years the Malthusian theory has received new support in the rapid change of ideas as to the origin of man and the genesis of species. That Buckle was right in saying that the promulgation of the Malthusian theory marked an epoch in the history of speculative thought could, it seems to me, be easily shown; yet to trace its influence in the higher domains of philosophy, of which Buckle’s own work is an example, would, though extremely interesting, carry us beyond the scope of this investigation. But how much be reflex and how much original, the support which is given to the Malthusian theory by the new philosophy of development, now rapidly spreading in every direction, must be noted in any estimate of the sources from which this theory derives its present strength. As in political economy, the support received from the doctrine of wages and the doctrine of rent combined to raise the Malthusian theory to the rank of a central truth, so the extension of similar ideas to the development of life in all its forms has the effect of giving it a still higher and more impregnable position. Agassiz, who, to the day of his death, was a strenuous opponent of the new philosophy, spoke of Darwinism as ”Malthus all over,“ Ref. 016 and Darwin himself says the struggle for existence ”is the doctrine of Malthus applied with manifold force to the whole animal and vegetable kingdoms. Ref. 017
It does not, however, seem to me exactly correct to say that the theory of development by natural selection or survival of the fittest is extended Malthusianism, for the doctrine of Malthus did not originally and does not necessarily involve the idea of progression. But this was soon added to it. McCulloch Ref. 018 attributes to the ”principle of increase“ social improvement
