The Commune could maintain itself and consolidate its position only by a determined struggle with the Versaillese. The latter, on the other hand, had a large number of agents in Paris. Fighting with the agents of Thiers, the Commune could not abstain from destroying the Versaillese at the front and in the rear. If its rule had crossed the bounds of Paris, in the provinces it would have found--during the process of the civil war with the Army of the National Assembly--still more determined foes in the midst of the peaceful population. The Commune when fighting the royalists could not allow freedom of speech to royalist agents in the rear. Kautsky, in spite of all the happenings in the world to-day, completely fails to realize what war is in general, and the civil war in particular. He does not understand that every, or nearly every, sympathizer with Thiers in Paris was not merely an "opponent" of the Communards in ideas, but an agent and spy of Thiers, a ferocious enemy ready to shoot one in the back. The enemy must be made harmless, and in wartime this means that he must be destroyed. The problem of revolution, as of war, consists in breaking the will of the foe, forcing him to capitulate and to accept the conditions of the conqueror. The will, of course, is a fact of the physical world, but in contradistinction to a meeting, a dispute, or a congress, the revolution carries out its object by means of the employment of material resources--though to a less degree than war. The bourgeoisie itself conquered power by means of revolts, and consolidated it by the civil war. In the peaceful period, it retains power by means of a system of repression. As long as class society, founded on the most deep-rooted antagonisms, continues to exist, repression remains a necessary means of breaking the will of the opposing side. Even if, in one country or another, the dictatorship of the proletariat grew up within the external framework of democracy, this would by no means avert the civil war. The question as to who is to rule the country, _i.e._, of the life or death of the bourgeoisie, will be decided on either side, not by references to the paragraphs of the constitution, but by the employment of all forms of violence. However deeply Kautsky goes into the question of the food of the anthropopithecus (see page 122 et seq. of his book) and other immediate and remote conditions which determine the cause of human cruelty, he will find in history no other way of breaking the class will of the enemy except the systematic and energetic use of violence. The degree of ferocity of the struggle depends on a series of internal and international circumstances. The more ferocious and dangerous is the resistance of the class enemy who have been overthrown, the more inevitably does the system of repression take the form of a system of terror.
