The history of all countries shows that the working class, exclusively by its own effort, is able to develop only trade union consciousness, i.e., it may itself realize the necessity for combining in unions, for fighting against the employers and for striving to compel the government to pass necessary labor legislation, etc. The theory of socialism, however, grew out of the philosophic, historical and economic theories that were elaborated by the educated representatives of the propertied classes, the intellectuals. According to their social status, the founders of modern scientific socialism, Marx and Engels themselves belonged to the bourgeois intelligentsia. Similarly, in Russia, the theoretical doctrine of Social Democracy [Note: By "social democracy" Lenin means revolutionary political Marxism, not the later concept of "moderate" socialism] arose quite independently of the spontaneous growth of the labor movement; it arose as a natural and inevitable outcome of the development of ideas among the revolutionary socialist intelligentsia. At the time of which we are speaking, i.e., the middle of the nineties, this doctrine not only represented the completely formulated program of the Emancipation of Labor group, but had already won the adherence of the majority of the revolutionary youth in Russia. . .
