To look at the root, to look for the root causes, to think critically, to question interpretation (Foucault) . The very course of thought is scientifically MARXISM. In philosophy, Marxism is based on everything human - the ideals of altruism, a classless society and opposes Nietzsche with his rule of the chosen and "finish off the falling" Scientific worldview + human values is Marxism. Scientifically, you can prove the course of history towards communism and the crimes of the parasitism of the bourgeoisie, but you also need communist altruistic ideals and morality, so that the worldview is not just scientific, but also goes for the common good, and not for the personal. The personal will lead a person nowhere. The endless development of science and Marxism is the only possible non-apocalyptic development of history. And so far, the whole history has been moving forward in a scientific and Marxist way. Perhaps in a spiral(Lenin), but on the whole forward. All branches of psychology and biology, etc. are built on the principles of Marxism. After all, Marxism is the highest stage of post-Hegelian philosophy, and philosophy is the mother of all sciences.
