Value-form
The Western Left academics are nowadays very happy to talk about "varieties of capitalism", but talking about "varieties of socialism" remains almost an absolute "no-no". Most Marxists continue to believe in "only one" (Marxian) socialism: either that, or nothing at all. "Either" a society or movement conforms to the true concept of socialism, "or" it does not; and if it does not, it "cannot be" socialism. However, precisely "because" there are many different Marxist beliefs about socialism, Marxists cannot agree among themselves whether Soviet-type societies were socialist, capitalist, or something else. Some countries meet with the moral expectations which Marxists have, and others do not.Originally Marx and Engels themselves had heckled the advocates of "true socialism", but later Friedrich Engels and Karl Kautsky promoted Marxist socialism as the one and true "scientific socialism" within the Socialist International. When he was 43 years old, Lenin stated: "The Marxist doctrine is omnipotent because it is true". Lenin's Communist International (a deliberate split with the social democrats) adopted Marxist socialism as its official political doctrine.
Georges Sorel
Sorel's was a voluntarist Marxism: he rejected those Marxists who believed in inevitable and evolutionary change, emphasizing instead the importance of will and preferring direct action. These approaches included general strikes, boycotts, and constant disruption of capitalism with the goal being to achieve worker control over the means of production. Sorel's belief in the need for a deliberately conceived "myth" to sway crowds into concerted action was put into practice by mass fascist movements in the 1920s. The epistemic status of the idea of "myth" is of some importance, and is essentially that of a working hypothesis, with one fundamental peculiarity: it is an hypothesis which we do not judge by its closeness to a "Truth", but by the practical consequences which stem from it. Thus, whether a political myth is of some importance or not must be decided, in Sorel's view, on the basis of its capacity to mobilize human beings into political action; the only possible way for men to ascend to an ethical life filled by the character of the sublime and to achieve deliverance. Sorel believed the "energizing myth" of the general strike would serve to enforce solidarity, class consciousness and revolutionary élan among the working class. The "myth" that the fascists would appeal to, however, was that of the race, nation, or people, as represented by the state. Historian Zeev Sternhell mentions frequently Sorel as one of the men who led the way to the fusion of the left-wing revisionists and of the right-wing ultranationalists into what later became fascism. Sorel's vision of socialism was "a-Marxist, anti-Marxist, eventually post-Marxist revisionist". Sternhell says that "the socialism designed as 'ethical socialism' by Sorel, Robert Michels and Arturo Labriola [...] will play a huge role in the evolution of the socialist nationalist synthesis, in the eve of 1914 and in the Interwar".
