So long as an individual, whether person or state, has only his own arms to depend upon in order to defend his rights by arms, then he must be stronger than anyone likely to challenge those rights. Which means that that other is deprived of similar defense. Within the frontiers man long ago made the discovery that the only way out of that dilemma is for the community, by putting its combined power behind a protective law, to assume the defense of the individual. Defense must be a communal, a collective function, or it cannot exist effectively at all.
