Marxism

Followers of Marx have frequently debated amongst themselves over how to interpret Marx's writings and apply his concepts to the modern world.^[235] The legacy of Marx's thought has become contested between numerous tendencies, each of which sees itself as Marx's most accurate interpreter. In the political realm, these tendencies include Leninism, Stalinism, Trotskyism, Maoism, Luxemburgism, and libertarian Marxism.^[235] Various currents have also developed in academic Marxism, often under influence of other views, resulting in structuralist Marxism, historical Marxism, phenomenological Marxism, Analytical Marxism and Hegelian Marxism.^[235] The Marxist revolutionary Che Guevara summed up his own appeal to Marxism by stating that Marx produced "a qualitative change in the history of social thought. He interprets history, understands its dynamic, predicts the future, but in addition to predicting it, he expresses a revolutionary concept: the world must not only be interpreted, it must be transformed."^[236]

Founder of social science

Marx is typically cited, along with Émile Durkheim and Max Weber, as one of the three principal architects of modern social science.^[13] In contrast to philosophers, Marx offered theories that could often be tested with the scientific method.^[10] Both Marx and Auguste Comte set out to develop scientifically justified ideologies in the wake of European secularisation and new developments in the philosophies of history and science. Working in the Hegelian tradition, Marx rejected Comtean sociological positivism in attempt to develop a science of society.^[237] In modern sociological theory, Marxist sociology is recognised as one of the main classical perspectives. Isaiah Berlin considers Marx the true founder of modern sociology, "in so far as anyone can claim the title."^[238]
