There have been a number of criticisms of orthodox Marxism from within the socialist movement. From the 1890s during the Second International,
Eduard Bernstein and others developed a position known as
revisionism, which sought to revise Marx's views based on the idea that the progressive development of capitalism and the extension of democracy meant that gradual, parliamentary reform could achieve socialism. But Bernstein himself was a revolutionary and joined the Independent Social Democratic Party in Germany which advocated for a socialist republic in 1918. This view was contested by orthodox Marxists such as Kautsky as well as by the young
György Lukács, who in 1919 clarified the definition of orthodox Marxism as thus: [O]rthodoxy refers exclusively to method. It is the scientific conviction that dialectical materialism is the road to truth and that its methods can be developed, expanded and deepened only along the lines laid down by its founders. It is the conviction, moreover, that all attempts to surpass or 'improve' it have led and must lead to over-simplification, triviality and eclecticism.
Western Marxism, the intellectual Marxism which developed in Western Europe from the 1920s onwards, sought to make Marxism more "sophisticated", open and flexible by examining issues like culture that were outside the field of orthodox Marxism. Western Marxists, such as
György Lukács,
Karl Korsch,
Antonio Gramsci and the
Frankfurt School, have tended to be open to influences orthodox Marxists consider
bourgeois, such as
psychoanalysis and the
sociology of
Max Weber. Marco Torres illustrates the shift away from orthodox Marxism in the Frankfurt School: In the early 1920s, the original members of the Frankfurt Institute—half forgotten names such as
Carl Grünberg,
Henryk Grossman and
Karl August Wittfogel, were social scientists of an orthodox Marxist conviction. They understood their task as an advancement of the sciences that would prove useful in solving the problems of a Europe-wide transition into socialism, which they saw, if not as inevitable, at least as highly likely. But as
fascism reared its head in Germany and throughout Europe, the younger members of the Institute saw the necessity for a different kind of Marxist Scholarship. Beyond accumulating knowledge relevant to an orthodox Marxist line, they felt the need to take the more critical and negative approach that is required for the maintenance of an integral and penetrating understanding of society during a moment of reaction. This could be described as the politically necessary transition from Marxist positive science to
Critical Theory. In parallel to this,
Cedric Robinson has identified a
Black Marxist tradition, including people like
C.L.R. James, Walter Rodney and
W. E. B. Du Bois, who have opened Marxism to the study of race, "stretching" it beyond orthodox Marxism. In the postwar period, the
New Left and
new social movements gave rise to intellectual and political currents which again challenged orthodox Marxism. These include Italian
autonomism, French
Situationism, the Yugoslavian
Praxis School, and British
cultural studies. == See also ==
