ON JUSTICE.

human justice. The degree of justice and the degree of organization simultaneously make advances. These are shown alike by the entire human race, and by its superior varieties as contrasted with its inferior.

We saw that a high species of animals is distinguished from a low species in the respect that since its aggregate suffers less mortality from destructive agencies, each of its members continues on the average for a longer time subject to the normal relation between conduct and consequence; and here we see that the human race as a whole, far lower in its rate of mortality than nearly all races of inferior kinds, usually subjects its members for much longer periods to the good and evil results of well-adapted and ill-adapted conduct. We also saw that as, among the higher animals, a greater average longevity makes it possible for individual differences to show their effects for longer periods, it results that the unlike fates of different individuals are to a greater extent determined by that normal relation between conduct and consequence which constitutes justice; and we here see that in mankind unlikenesses of faculty in still greater degrees, and for still longer periods, work out their effects in advantaging the superior and disadvantaging the inferior in the continuous play of conduct and consequence.

Similarly is it with the civilized varieties of mankind as compared with the savage varieties. A still further diminished rate of mortality implies that there is a relatively still larger proportion, the members of which, during long lives, gain good from well-adapted acts, and suffer evil from ill-adapted ones. While also it is manifest that both the greater differences of longevity among individuals, and the greater differences of social position, imply that in civilized societies more than in savage societies, differences of endowment and consequent differences of conduct are enabled to cause their appropriate differences of results, good or evil: the justice is greater.

More clearly in the human race than in lower races are we shown that gregariousness establishes itself because it profits the variety in which it arises, partly by furthering general safety and partly by facilitating sustentation. And we are shown that the degree of gregariousness is determined by the degree in which it thus subserves the interests of the variety. For where the variety is one of which the members live on wild food, they associate only in small groups: game and fruits widely distributed can support these only. But greater gregariousness arises where agriculture makes possible the support of a large number on a small area; and where the accompanying development of industries introduces many and various co-operations.
