The real test of Marxism is thus whether it succeeds in becoming the social and political consciousness that changes reality. This is because dialectical materialism aims to be a theory with practical import – it does not aim to describe history and reality but to change it. We saw that for Marx anything that remains unrealized in a sense remains unreal, and this includes revolutionary theory. As he puts it in the 2nd Thesis on Feuerbach: “The question whether objective truth can be attributed to human thinking is not a question of theory but is a practical question. Man must prove the truth — i.e. the reality and power, the this-sidedness of his thinking in practice.” Only if the proletariat realizes communism through revolution will Marxism be vindicated.
