Now, as society grows, the disposition to continue previous, social adjustments tends to lodge this collective power, as it arises, in the hands of a portion of the community; and this unequal distribution of the wealth and power gained as society advances tends to produce greater inequality, since aggression grows by what it feeds on, and the idea of justice is blurred by the habitual toleration of injustice. In this way the patriarchal organization of society can easily grow into hereditary monarchy, in which the king is as a god on earth, and the masses of the people mere slaves of his caprice. It is natural that the father should be the directing head of the family, and that at his death the eldest son, as the oldest and most experienced member of the little community, should succeed to the headship. But to continue this arrangement as the family expands, is to lodge power in a particular line, and the power thus lodged necessarily continues to increase, as the common stock becomes larger and larger, and the power of the community grows. The head of the family passes into the hereditary king, who comes to look upon himself and to be looked upon by others as a being of superior rights. With the growth of the collective power as compared with the power of the individual, his power to reward and to punish increases, and so increase the inducements to flatter and to fear him; until finally, if the process be not disturbed, a nation grovels at the foot of a throne, and a hundred thousand men toil for fifty years to prepare a tomb for one of their own mortal kind. So the war-chief of a little band of savages is but one of their number, whom they follow as their bravest and most wary. But when large bodies come to act together, personal selection becomes more difficult, a blinder obedience becomes necessary and can be enforced, and from the very necessities of warfare when conducted on a large scale absolute power arises. And so of the specialization of function. There is a manifest gain in productive power when social growth has gone so far that instead of every producer being summoned from his work for fighting purposes, a regular military force can be specialized; but this inevitably tends to the concentration of power in the hands of the military class or their chiefs. The preservation of internal order, the administration of justice, the construction and care of public works, and, notably, the observances of religion, all tend in similar manner to pass into the hands of special classes, whose disposition it is to magnify their function and extend their power.
