| The question of whether war is inevitable is one which has concerned many of the world's great writers. Before 1 this question, it will be useful to introduce some 2 concepts. Conflict, 3 as opposition among social units directed against one another, is 4 from competition, which means opposition among social units independently seeking to obtain something which is 5 short supply. Competitors may not know about one another, while those who 6 in a conflict do. Conflict and competition are both classes of opposition. The meaning of opposition has been stated as a process by which social units function in the disservice of one another; opposition is thus contrasted to cooperation, a 7 by which social units function in the service of one another. These 8 are necessary because it is important to emphasize that competition between individuals or groups is inevitable in a world of limited 9 , but conflict isn't. Conflict, nevertheless, is very likely to occur and is probably an essential and desirable element of human societies. Many authors have 10 their arguments that war cannot be avoided on the idea that in the struggle for existence among groups of animals, only those which are best 11 remain alive. In general, however, this struggle in nature is competition, not conflict. Those who fail in this competition 12 starve to death or are 13 by other types of animals. This struggle for existence is not similar to human war, but is like the competition of 14 for jobs, markets, and materials. The most important quality of this struggle is the 15 for the necessities of life that are not enough to satisfy all. | |||
