IX evitable in the long run ", the present trend of human evolution as typified in the rise of totalitarian dictator- ships is against it. This argument ignores the pheno- menon of dialectical transformations and mutations in nature and history. A close study of natural and his- torical phenomena shows that when a particular ten- dency in nature or society has reached its peak, it is very often ripe for a mutation, i. e., transformation into its opposite by a sudden leap. During the last war the culmination of the power of armaments gave rise to the technique of frightfulness which means you do not need to kill if you can demonstrate your undoubted capacity to kill. By the use of this technique it was found possible by totalitarian powers to subdue and enslave whole nations almost without firing a shot. It is not without significance that although the destructive power of armaments and the numbers involved in the last World War were far greater than in World War I, actual casualties were less. Proceeding on this analogy, it should not be difficult to visualize that as the number of people groaning under the iron heel of militarism grows, the stage is set for the discovery that if the oppressed masses simply shed the fear of death, it might not be necessary for them to die to regain their freedom. The deadlier the weapons of destruction be- come, the greater is the chance of humanity's learning to confront them with a power of an altogether different kind against which they cannot prevail. Armaments can but destroy. Yet, total destruction is not what the tyrant seeks, but co-operation, willing or forced, of the victim and this no power of armaments can extract from a people if they have the strength to say ' No '. The moment, therefore, the people become aware of soul force or the power of the spirit, which armaments can neither destroy nor subdue, the arms will be rendered useless and the citadel of tyranny will fall. The earliest and perhaps the most brilliant recorded historical instance of the triumph of this power of the spirit is to be found in the encounter on the plain of
