Nietzsche's Philosophical Lineage: Influences and 20th-Century Legacy

Friedrich Nietzsche: Influences and Philosophical Impact

Nietzsche's thinking is the result of the most significant and diverse currents of thought and announces some of the most important philosophical movements of the 20th century.

Key Philosophical Influences on Nietzsche

Specifically, we identify the following major influences:

• Post-Kantian Critique: The analysis of the conditions of knowledge, gained from Descartes to Kant, leads to Nietzsche's rejection of reason as a tool capable of capturing reality itself.
• Schopenhauer's Will: Nietzsche follows Schopenhauer in his interpretation of Kant, reducing the world to appearance (Vorstellung) and seeing things through the lens of the Will to Live. He thus removes the 'thing-in-itself' and understands reality as perspective, meaning any truth is merely interpretation (perspectivism).
• Humean Empiricism: Aligning with Hume against Descartes, Nietzsche reaffirms the crucial role of the senses and eliminates the need for metaphysical notions, reducing concepts to psychological habits.
• The Sophists: From the ancient world, he focuses on the Sophists, learning that language is relative, which forms the basis for his perspectivism.
• Classical Admiration: We cannot forget Nietzsche's admiration for the classical world, specifically those aspects far from the philosophy of Socrates and Plato.

Nietzsche's Rejections and Criticisms

Nietzsche defined his philosophy largely through opposition to established traditions:

• Socrates and Plato: Nietzsche attributes the decline of Western culture to the philosophy of Plato and his teacher Socrates.
• Transcendent Reality: He rejects any transcendent reality, disregarding any theory (such as those favored by Plato and Christianity) that defends the existence of a world different from the one given here and now.
• Rationalism and Positivism: He criticizes the deification of reason performed by Hegel, the rationalist tradition, and positivism.
• Morality and Religion: Nietzsche's criticism of religion and bourgeois morality extends themes previously addressed by Feuerbach and the Hegelian Left.

Subsequent Impact and Legacy

Nietzsche, who died in 1900, has been one of the most influential philosophers in subsequent thought. His legacy spans multiple disciplines:

• Psychoanalysis (Freud): His focus on irrational impulses and the Will prefigures the inquiry into the unconscious by Sigmund Freud and the development of psychoanalysis.
• Analytic Philosophy: His attention to language and its limitations prefigures the concerns of analytic philosophy, notably in the works of Russell and Wittgenstein.
• Existentialism (Sartre): He is a great benchmark for philosophies of life and existentialism, which, starting from a human, mundane perspective, necessitates creating a new hierarchy of values (e.g., Jean-Paul Sartre).
• Postmodernism and Hermeneutics: Nietzsche serves as a foundational model for postmodern philosophy. He is also a key reference for the hermeneutic philosophy of Hans-Georg Gadamer and Martin Heidegger, due to his concept of truth as interpretation.

Any serious criticism of culture must acknowledge Nietzsche.
