20世纪20年代,苏共党内先后出现托洛茨基主义、新反对派、托季联盟和布哈林集团等党内派别和派别活动。以斯大林为首的党中央同它们进行了不调和的斗争。从中可以得出几点启示:正确的党内斗争是达到党的团结的重要武器之一;无产阶级政党必须旗帜鲜明地反对党内分派;反对党内派别和派别活动并非禁止党内存在不同意见;无产阶级政党及其领袖既要勇于自我批评,又要善于辨别两种性质不同的错误。 In the 1920s, there were successively party factions and factional activities in the CPSU such as Trotskyism, the New Opposition, the Tudor Union and the Bukharin Group. The party Central Committee headed by Stalin has conducted an intransigent struggle with them. From which we can draw some enlightenment: Correct in-party struggle is one of the most important weapons for achieving the party’s unity; the proletarian party must oppose intra-party distribution in a clear-cut manner; factional and factional opposition within the party does not forbid the existence of different opinions within the party; and the proletariat Political parties and their leaders should both brave self-criticism and be good at identifying two different kinds of mistakes.
