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.
Prison Notebooks
By virtue of his belief that human history and collective praxis determine whether any philosophical question is meaningful or not, Gramsci's views run contrary to the metaphysical materialism and 'copy' theory of perception advanced by Engels and Lenin, though he does not explicitly state this. For Gramsci, Marxism does not deal with a reality that exists in and for itself, independent of humanity. The concept of an objective universe outside of human history and human praxis was, in his view, analogous to belief in God; there could be no objectivity, but only a universal intersubjectivity to be established in a future communist society. Natural history was thus only meaningful in relation to human history. On his view philosophical materialism, like primitive common sense, resulted from a lack of critical thought, and could not, as Lenin claimed, be said to oppose religious superstition. Despite this, Gramsci resigned himself to the existence of this arguably cruder form of Marxism: the proletariat's status as a dependent class meant that Marxism, as its philosophy, could often only be expressed in the form of popular superstition and common sense. Nonetheless, it was necessary to effectively challenge the ideologies of the educated classes, and to do so Marxists must present their philosophy in a more sophisticated guise, and attempt to genuinely understand their opponents’ views.
