Nietzscheanism–Marxism is a hybrid approach that combines ideas from Nietzsche and Marx, used more in critical theory than as a formal doctrine.

From Marx it takes the critique of capitalism, class power, ideology, and how material conditions shape society.

From Nietzsche it takes the critique of traditional morality, herd thinking, resentment, and the way values are created and imposed.

Power is understood as economic (classes, production) as well as cultural and psychological (norms, values, identity).

It distrusts universal moralities and understands values as tools that serve interests and power structures.

It seeks liberation not only from economic exploitation, but also from internalized norms and submissive identities.

uses the vitalist myth to fuel the revolution.
