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.
