After the first rude work of shaping the body of ancient experience into law was done, there remained the larger and more difficult task of continuing the development of the sympathetic motives with a corresponding amplification of customs and statutes so that the steps of advance should be duly embodied in these rules of conduct. The stages of this purely human attainment have been slowly taken, the onward way has been effectively won but by few peoples. A part of the slowness in advance in the enlargement of the sympathetic motives beyond the stage which has been attained in the life below the human grade is to be accounted for in the fact that no sooner are laws formed than they become in a way sacred. If they be cast in the religious mould their sanctity may be such that they are almost beyond the reach of modification; even when they are secular the reverence for the wisdom of the forefathers naturally leads men to regard them as the ark of safety. Thus it has come about that the codification of the ancient sympathies, won by experience in the pre-human time and in the early life of man, has led to the institution of a barrier which makes further advance a matter of difficulty--one which, in the case of most peoples, binds them firmly to the past, arresting their sympathetic development at a point which it had attained when their laws were framed. This is, indeed, the position of nearly all the peoples except those of our own Aryan race. When the conditions of a people are fortunately such that they may continue their sympathetic growth, they proceed to carry onward the process of sympathetic enlargement, modifying their laws to suit the gains in understanding which come with this growth. It may be noticed that the development takes place most readily where the rules of conduct are embodied in statute law; for this law, being the evident result of human action, is manifestly alterable in a way that cannot be taken when the prescriptions are supposed to rest on divine commands. Under such conditions of statute law men are freer to advance than they can possibly be where the rules of action are in the form of revered precepts, such as guide the peoples who are accustomed to base their action on the books which they esteem as sacred. Endowed with this element of freedom, the peoples of our own Aryan race--and, fortunately, the most advanced of all its varieties, the English-speaking part of the folk--have, by the divine impulse towards moral advancement, been led to make a great extension of the sympathetic motives. The first step in this direction seems to have been towards the mitigation of the horrors of war, which of old meant the slavery or slaughter of the prisoners. Under the dictates of the developing spirit of mercy and without written law, these brutal actions have been limited until the dogs of war are allowed to rend only in the hour of battle. In this day the man who slays the wounded or robs the dead is esteemed an outlaw.
