Even among savages, where the degradation of women, infanticide, vice, famine, war, and disease are active instruments of decimation, it will be found that the average population, generally speaking, presses hard against the limits of the average food. Among modern pastoral nations the principal checks which keep the population down to the level of the means of subsistence are: restraint from inability to obtain a wife, vicious habits with respect to women, epidemics, war, famine, and the diseases arising from extreme poverty. In modern Europe we find similar preventive and positive checks, in varying proportions, to undue increase of population. In England and Scotland the preventive check to population prevails in a considerable degree. A man of liberal education, with an income only just sufficient to enable him to associate in the rank of gentlemen, must feel absolutely certain that if he marry and have a family he shall be obliged to give up all his former connections. The woman whom a man of education would naturally choose is one brought up in similar refined surroundings. Can a man easily consent to place the object of his affections on a lower social plane? Such considerations certainly prevent many of the better classes from early marriage; and those who marry in the face of such considerations too frequently justify the forebodings of the prudent. The sons of tradesmen and farmers are exhorted not to marry till they have a sufficient sure income to support a family, and often accordingly postpone marriage till they are far advanced in life. The labourer who earns eighteenpence or two shillings a day, as a single man, will hesitate to divide that pittance among four or five, seeing the risks such poverty involves. The servants who live in the families of the rich have yet stronger inducements to forego matrimony. They live in comparative comfort and luxury, which as married men they could not enjoy. The prolific power of nature is very far from being called fully into action in Great Britain. And yet, when we contemplate the insufficiency of the price of labour to maintain a large family, and the amount of mortality which arises directly and indirectly from poverty, and add to this the crowds of children prematurely cut off in large towns, we shall be compelled to acknowledge that, if the number born annually were not greatly thinned by this premature mortality, the funds for the maintenance of labour must increase with much greater rapidity than they have ever hitherto done in order to find work and food for the additional numbers that would then grow up to manhood. Those, therefore, who live single, or marry late, do not by such conduct contribute in any degree to diminish the actual population, but merely to diminish the proportion of premature mortality, which would otherwise be excessive; and consequently, from this point of view, do not seem to deserve any very severe reprobation or punishment.
