But consider. Increase of descendants does not show increase of population. It could only do this when the breeding was in and in. Smith and his wife have a son and daughter, who marry respectively some one else’s daughter and son, and each have two children. Smith and his wife would thus have four grandchildren; but there would be in the one generation no greater number than in the other—each child would have four grandparents. And supposing this process were to go on, the line of descent might constantly spread out into hundreds, thousands and millions; but in each generation of descendants there would be no more individuals than in any previous generation of ancestors. The web of generations is like lattice-work or the diagonal threads in cloth. Commencing at any point at the top, the eye follows lines which at the bottom widely diverge; but beginning at any point at the bottom, the lines diverge in the same way to the top. How many children a man may have is problematical. But that he had two parents is certain, and that these again had two parents each is also certain. Follow this geometrical progression through a few generations and see if it does not lead to quite as “striking consequences” as Mr. Malthus’ peopling of the solar systems. But from such considerations as these let us advance to a more definite inquiry. I assert that the cases commonly cited as instances of over-population will not bear investigation. India, China, and Ireland furnish the strongest of these cases. In each of these countries, large numbers have perished by starvation and large classes are reduced to abject misery or compelled to emigrate. But is this really due to over-population? Comparing total population with total area, India and China are far from being the most densely populated countries of the world. According to the estimates of MM. Behm and Wagner, the population of India is but 132 to the square mile and that of China 119, whereas Saxony has a population of 442 to the square mile; Belgium 441; England 422; the Netherlands 291; Italy 234 and Japan 233.[22] There are thus in both countries large areas unused or not fully used, but even in their more densely populated districts there can be no doubt that either could maintain a much greater population in a much higher degree of comfort, for in both countries is labor applied to production in the rudest and most inefficient ways, and in both countries great natural resources are wholly neglected. This arises from no innate deficiency in the people, for the Hindoo, as comparative philology has shown, is of our own blood, and China possessed a high degree of civilization and the rudiments of the most important modern inventions when our ancestors were wandering savages. It arises from the form which the social organization has in both countries taken, which has shackled productive power and robbed industry of its reward.
