Communism as the minimum objective has been the only theme of the political science of the transition. Ever since the Bernsteindebatte, both the revolutionary and the reformist traditions have considered socialism as a transitional period between capitalism and communism, and therefore they have considered socialism as a concept that is separate from both the former stage and the latter. Communism existed in the transition as its motor, not as an ideal but as an active and effective subjectivity that confronted the complex of conditions of capitalist production and reproduction, reappropriating them and, at this point, destroying and going beyond them. Much more important are the prerequisites of communism that, in the contemporary era, can be identified in the evolution of the organization of labor. Taylorism determined an extraordinary process of abstraction of labor-power. In the development of struggles in the 1960s and 1970s, the abstraction of labor went beyond its subjective dimensions and spilled over to the terrain of subversion.
