Malthus's survey of different countries showed how various are the 'checks' by which population is limited in various countries. We take a glance at all nations through all epochs of history. In the South Sea we find a delicious climate and a fertile soil, where population is mainly limited by vice, infanticide, and war; and where, in spite of these influences, the population multiplies at intervals till it is killed off by famine. In China, a vast and fertile territory, inhabited by an industrious race, in which agriculture has always been encouraged, marriage stimulated, and property widely diffused, has facilitated the production of a vast population in the most abject state of poverty, driven to expose children by want, and liable at intervals to destructive famines. In modern Europe, the checks appear in the most various forms; in Switzerland and Norway a frugal population in small villages sometimes instinctively understands the principle of population, and exhibits the 'moral restraint,' while in England the poor-laws are producing a mass of hopeless and inert pauperism. Consideration of these various cases, and a comparison of such records as are obtainable of the old savage races, of the classical states of antiquity, of the Northern barbarians and of the modern European nations, suggests a natural doubt. Malthus abundantly proves what can hardly be denied, that population has everywhere been found to press upon the means of subsistence, and that vice and misery are painfully abundant. But does he establish or abandon his main proposition? He now asserts the 'tendency' of population to outrun the means of subsistence. Yet he holds unequivocally that the increase of population has been accompanied by an increased comfort; that want has diminished although population has increased; and that the 'preventive' check is stronger than of old in proportion to the positive check. Scotland, he says,[225] is 'still overpeopled, but not so much as when it contained fewer inhabitants.' Many nations, as he points out in general terms, have been most prosperous when most populous.[226] They could export food when crowded, and have ceased to import it when thinned. This, indeed, expresses his permanent views, though the facts were often alleged by his critics as a disproof of them. Was not the disproof real? Does not a real evasion lurk under the phrase 'tendency'? You may say that the earth has a tendency to fall into the sun, and another 'tendency' to move away from the sun. But it would be absurd to argue that we were therefore in danger of being burnt or of being frozen. To explain the law of a vital process, we may have to analyse it, and therefore to regard it as due to conflicting forces; but the forces do not really exist separately, and in considering the whole concrete phenomenon we must take them as mutually implied. A man has a 'tendency' to grow too fat; and another 'tendency' to grow too thin. That surely means that on the whole he
