"Another veteran communist calling for the revision of conventional contemporary Marxism was Herbert Marcuse. After emigrating from Nazi Germany in 1933, he took American citizenship and wrote prolifically about the need to graft several intellectual trends of the twentieth century – especially Freudianism and German sociology – on to the tree of the Marxist tradition. Marcuse rejected Stalin’s version of communism as dogmatic, narrow and plain wrong in its interpretation of Marx. He was a freer spirit than Lukács and refused to recognise Lenin as an absolute authority. He insisted that sexual drives as well as economic imperatives help to explain the mechanisms of politics and society. He scorned the Communist Party of the USA and refused to align himself with any organisation. His experiences as a young militant in Europe had eroded his faith in the revolutionary potential of the working class. Marcuse saw well-paid industrial workers as constituting one of the obstacles to humanity’s liberation from oppression. Based on the San Diego campus of the University of California, he counted instead upon the unemployed, the vagabond poor and the Hispanic immigrants; he also had a soft spot for college students. He regarded these groups as living in detachment from ‘bourgeois’ society and ready to overcome the ‘one-dimensional’ aspects of contemporary capitalist existence. Marcuse’s forte was as a philosopher. His preoccupation with epistemology and dialectics was typical of a growing trend among Marxist writers seeking to challenge the Marxism that had been customary since 1917."
