ABSTRACT
The fact that the process of selectivity has been operating throughout human history suggests that the phenomenon may be beyond man's control. The principle of selectivity, of course, is not confined to the human race. Both human and non-human species develop according to principles of selection. In the human species, natural selection became social selection when the species developed a new pattern of organized living. As the people gain a higher standard of living, leadership advances the use of technological devices like mass production. The most powerful instrument of exploitation of the people is war. The instrument of war has thus created divided loyalties and competing aspirations. Nuclear war, it is asserted, would mean the end of Western, perhaps of all civilization, even the end of the human race. The wars will occur as soon as one or more of the aggressive powers develops weapons of defense to a point that their ruling powers consider war a justifiable risk.
