examining and continuing the tradition of the CPC and embracing its revolutionary past. The fidelity of those varied revolutionaries, leaders and parties to the work of Karl Marx is highly contested and has been rejected by many Marxists and other socialists alike. Socialists in general and socialist writers, including Dimitri Volkogonov, acknowledge that the actions of authoritarian socialist leaders have damaged "the enormous appeal of socialism generated by the October Revolution." Criticism Criticism of Marxism has come from various political ideologies and academic disciplines. This includes general criticism about lack of internal consistency, criticisms related to historical materialism, that it is a type of historical determinism, the necessity of suppression of individual rights, issues with the implementation of communism and economic issues such as the distortion or absence of price signals and reduced incentives. In addition, empirical and epistemological problems are frequently identified.

Additionally, some intellectual critiques of Marxism contest certain assumptions prevalent in Marx's thought and Marxism after him without rejecting Marxist politics. Other contemporary supporters of Marxism argue that many aspects of Marxist thought are viable but that the corpus is incomplete or outdated regarding certain aspects of economic, political or social theory. They may combine some Marxist concepts with the ideas of other theorists such as Max Weber—the Frankfurt School is one example. General Philosopher and historian of ideas Leszek Kołakowski pointed out that "Marx's theory is incomplete or ambiguous in many places, and could be 'applied' in many contradictory ways without manifestly infringing its principles." Specifically, he considers "the laws of dialectics" as fundamentally erroneous, stating that some are "truisms with no specific Marxist content", others "philosophical dogmas that cannot be proved by scientific means", and some just "nonsense"; he believes that some Marxist laws can be interpreted differently, but that these interpretations still in general fall into one of the two categories of
