“Lenin’ s often-quoted speech to the Komsomol Congress on 2 October 1920 deals with ethical questions on similar lines, "We say that our morality is entirely subordinated to the interests of the proletariat’ s class struggle. Morality is what serves to destroy the old exploiting society and to unite all the working people around the proletariat, which is building up a new, a communist society … To a Communist all morality lies in this united discipline and conscious mass struggle against the exploiters. We do not believe in an eternal morality, and we expose the falseness of all the fables about morality" (Works, vol. 31, pp. 291-4). It would be hard to interpret these words in any other sense than that everything which serves or injures the party’ s aims is morally good or bad respectively, and nothing else is morally good or bad. After the seizure of power, the maintenance and strengthening of Soviet rule becomes the sole criterion of morality as well as of all cultural values. No criteria can avail against any action that may seem conducive to the maintenance of power, and no values can be recognized on any other basis. All cultural questions thus become technical questions and must be judged by the one unvarying standard; the "good of society" becomes completely alienated from the good of its individual members. It is bourgeois sentimentalism, for instance, to condemn aggression and annexation if it can be shown that they help to maintain Soviet power; it is illogical and hypocritical to condemn torture if it serves the ends of the power which, by definition, is devoted to the "liberation of the working masses". Utilitarian morality and utilitarian judgements of social and cultural phenomena transform the original basis of socialism into its opposite. All phenomena that arouse moral indignation if they occur in bourgeois society are turned to gold, as if by a Midas touch, if they serve the interests of the new power: the armed invasion of a foreign state is liberation, aggression is defence, tortures represent the people’ s noble rage against the exploiters. There is absolutely nothing in the worst excesses of the worst years of Stalinism that cannot be justified on Leninist principles, if only it can be shown that Soviet power was increased thereby.”
