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.
Socialism with Chinese characteristics
Mao said that the imposition of "progressive relations of production" would revolutionize production. His successor's rejection of this view according to A. James Gregor has thwarted the ideological continuity of Maoism—officially Mao Zedong Thought. Classical Marxism had argued that a socialist revolution would only take place in advanced capitalist societies and its success would signal the transition from a capitalist commodity-based economy to a "product economy" in which goods would be distributed for people's need and not for profit. If because of a lack of a coherent explanation in the chance of failure this revolution did not occur, the revolutionaries would be forced to take over the responsibilities of the bourgeoisie. Chinese communists are thus looking for a new Marxist theory of development. Party theorist Luo Rongqu recognized that the founders of Marxism had never "formulated any systematic theory on the development of the non-Western world" and said that the Communist Party of China should "establish their own synthesized theoretical framework to study the problem of modern development". According to A. James Gregor, the implication of this stance is that "Chinese Marxism is currently in a state of profound theoretical discontinuity".
