And here we are introduced to certain facts of profound significance. This conscious relinquishment of immediate and special good to gain distant and general good, while it is a cardinal trait of the self-restraint called moral, is also a cardinal trait of self-restraints other than those called moral--the restraints that originate from fear of the visible ruler, of the invisible ruler, and of society at large. Whenever the individual refrains from doing that which the passing desire prompts, lest he should afterward suffer legal punishment, or divine vengeance, or public reprobation, or all of them, he surrenders the near and definite pleasure rather than risk the remote and greater, though less definite, pains, which taking it may bring on him; and, conversely, when he undergoes some present pain, that he may reap some probable future pleasure, political, religious, or social. But though all these four kinds of internal control have the common character that the simpler and less ideal feelings are consciously overruled by the more complex and ideal feelings; and though, at first, they are practically co-extensive and undistinguished, yet, in the course of social evolution, they differentiate; and, eventually, the moral control, with its accompanying conceptions and sentiments, emerges as independent. Let us glance at the leading aspects of the process. While, as in the rudest groups, neither political nor religious rule exists, the leading check to the immediate satisfaction of each desire as it arises, is consciousness of the evils which the anger of fellow-savages may entail, if satisfaction of the desire is obtained at their cost. In this early stage the imagined pains which constitute the governing motive are those apt to be inflicted by beings of like nature, undistinguished in power: the political, religious, and social restraints are as yet represented only by this mutual dread of vengeance. When special strength, skill, or courage, makes one of them a leader in battle, he necessarily inspires greater fear than any other, and there comes to be a more decided check on such satisfactions of the desires as will injure or offend him. Gradually as, by habitual warfare, chieftainship is established, the evils thought of as likely to arise from angering the chief, not only by aggression upon him, but by disobedience to him, become distinguishable both from the smaller evils which other personal antagonisms cause, and from the more diffused evils thought of as arising from social reprobation. That is, political control begins to differentiate from the more indefinite control of mutual dread.
