Which philosophical movement is Friedrich Nietzsche associated with?

Friedrich Nietzsche is primarily associated with existentialism due to his exploration of themes such as individual existence, freedom, and the subjective nature of truth. Existentialism places a strong emphasis on the individual's experience and the meaning they create in their lives, a notion that Nietzsche profoundly addressed through concepts like the "will to power" and the idea of the "Übermensch" (or "Overman"), which challenges individuals to transcend societal norms and create their own values.

Nietzsche's work also examines the concept of nihilism, the idea that life lacks intrinsic meaning or value. This fundamental questioning of established truths and moral systems resonates deeply with existentialist philosophy, which often grapples with the absurdity of life and the responsibility of creating one's own meaning in a seemingly indifferent universe.

While Nietzsche's ideas have also been associated with postmodernism due to his critiques of objective truth and moral absolutes, existentialism more directly captures his emphasis on personal responsibility and the individual's quest for meaning. Thus, the association with existentialism is most fitting, as it encapsulates his philosophical inquiries into the human condition.
