THE STUDY OF SOCIOLOGY.

help them; and their life must also be like, in lacking that overflowing energy which, while it makes labors easy, makes enjoyments keen. In proportion as vigor declines, not only do the causes of pain multiply, while the tax on the energies becomes more trying, but the possibilities of pleasure decrease; many delights demanding, or accompanying, exertion are shut out; and others fail to raise the flagging spirits. So that, to sum up, lowering the average type of constitution to a level of strength below that which meets without difficulty the ordinary strains, and perturbations, and dangers, while it fails eventually to diminish the rate of mortality, makes life more a burden and less a gratification.

I am aware that this reasoning may be met by the criticism that, carried out rigorously, it would negative social ameliorations in general. Some, perhaps, will say that even those measures by which order is maintained might be opposed for the reason that there results from them a kind of men less capable of self-protection than would otherwise exist. And there will doubtless be suggested the corollary that no influences detrimental to health ought to be removed. I am not concerned to meet such criticisms, for the reason that I do not mean the conclusions above indicated to be taken without qualification. It is obvious enough that, up to a certain point, the removal of destructive causes leaves a balance of benefit. The simple fact, that, with a largely-augmented population, longevity is greater now than heretofore, goes far toward showing that, up to the time lived through by those who die in our day, there had been a decrease of the causes of mortality in some directions, greater than their increase in other directions. Though a considerable drawback may be suspected—though, on observing how few thoroughly-strong people we meet, and how prevalent are chronic ailments notwithstanding the care taken of health it may be inferred that bodily life now is lower in quality than it was, though greater in quantity—yet there has probably been gained a surplus of advantage. All I wish to show is, that there are limits to the good gained by a such a policy. It is supposed in the Legislature, and by the public at large, that, if, by measures taken, a certain number of deaths by disease have been prevented, so much pure benefit has been secured. But it is not so. In any case, there is a set-off from the benefit; and, if such measures are greatly multiplied, the deductions may eat up the benefit entirely, and leave an injury in its place. Where such measures ought to stop, is a question that may be left open. Here my purpose is simply to point out the way in which a far-reaching biological truth underlies rational conclusions in Sociology, and also to point out that formidable evils may arise from ignoring it.

Other evils, no less serious, are entailed by legislative actions and by actions of individuals, single and combined, which overlook or disregard a kindred biological truth. Besides an habitual neglect of the
