The question of the struggle of opposites includes the question of what is antagonism. Our answer is that antagonism is one form, but not the only form, of the struggle of opposites.
In human history, antagonism between classes exists as a particular manifestation of the struggle of opposites. Consider the contradiction between the exploiting and the exploited classes. Such contradictory classes coexist for a long time in the same society, be it slave society, feudal society or capitalist society, and they struggle with each other; but it is not until the contradiction between the two classes develops to a certain stage that it assumes the form of open antagonism and develops into revolution. The same holds for the transformation of peace into war in class society.
Before it explodes, a bomb is a single entity in which opposites coexist in given conditions. The explosion takes place only when a new condition, ignition, is present. An analogous situation arises in all those natural phenomena which finally assume the form of open conflict to resolve old contradictions and produce new things.
It is highly important to grasp this fact. It enables us to understand that revolutions and revolutionary wars are inevitable in class society and that without them, it is impossible to accomplish any leap in social development and to overthrow the reactionary ruling classes and therefore impossible for the people to win political power. Communists must expose the deceitful propaganda of the reactionaries, such as the assertion that social revolution is unnecessary and impossible. They must firmly uphold the Marxist-Leninist theory of social revolution and enable the people to understand that social revolution is not only entirely necessary but also entirely practicable, and that the whole history of mankind and the triumph of the Soviet Union have confirmed this scientific truth.
However, we must make a concrete study of the circumstances of each specific struggle of opposites and should not arbitrarily apply the formula discussed above to everything. Contradiction and struggle are universal and absolute, but the methods of resolving contradictions, that is, the forms of struggle, differ according to the differences in the nature of the contradictions. Some contradictions are characterized by open antagonism, others are not. In accordance with the concrete development of things, some contradictions which were originally non-antagonistic develop into antagonistic ones, while others which were originally antagonistic develop into non-antagonistic ones.
As already mentioned, so long as classes exist, contradictions between correct and incorrect ideas in the Communist Party are reflections within the Party of class contradictions. At first, with regard to certain issues, such contradictions may not manifest themselves as antagonistic. But with the development of the class struggle, they may grow and become antagonistic. The history of the Communist Party of the Soviet Union shows us that the contradictions between the correct thinking of Lenin and Stalin and the fallacious thinking of Trotsky, Bukharin and others did not at first manifest themselves in an antagonistic form, but that later they did develop into antagonism. There are similar cases in the history of the Chinese Communist Party. At first the contradictions between the correct thinking of many of our Party comrades and the fallacious thinking of Chen Tu-hsiu, Chang Kuo-tao and others also did not manifest themselves in an antagonistic form, but later they did develop into antagonism. At present the contradiction between correct and incorrect thinking in our Party does not manifest itself in an antagonistic form, and if comrades who have committed mistakes can correct them, it will not develop into antagonism. Therefore, the Party must on the one hand wage a serious struggle against erroneous thinking, and on the other give the comrades who have committed errors ample opportunity to wake up. This being the case, excessive struggle is obviously inappropriate. But if the people who have committed errors persist in them and aggravate them, there is the possibility that this contradiction will develop into antagonism.
