This has been made possible by the intimate intermingling of the people, the absence of racial rivalries, and the fact that the interests of all are identical in the matter of defense of life, property, and reputation; since, no matter how bad any individual may be, he wishes that others shall be good, in order that he himself may be safe.
The defense of reputation has two aspects: the practical and the sentimental.

The practical aspect regards the defense of that element of reputation which affects ability to "make a living"; while the sentimental aspect is concerned with the purely personal reputation of the individual, or with the reputation of an organization or a nation.

The sentimental aspect is much more important, especially in enlightened nations, than is realized by some who have not thought much about it; for there is, fortunately, in every decent man a craving for the esteem and even the affection of his fellow men; and a knowledge that, no matter how wealthy or powerful he may be, he cannot be happy if he knows that he is despised.
The fact that individuals organize to acquire the strength of united effort brings about, among organizations, a spirit of competition like that among individuals.

It is more intense, however, because no man alone can get up the enthusiasms that ten men acting together can get up, and ten men cannot get up as much as a thousand.

The longer any organization is maintained, the sharper this spirit of rivalry grows to be, owing to the feeling of clanship that propinquity and material interests evoke.
