Friedrich Nietzsche is credited with several achievements in philosophy, most notably his critique of traditional morality and the concept of nihilism. His proclamation of the "death of God" challenged the foundations of Western thought, suggesting that accepted moral values were unfounded. Nietzsche's idea of the Übermensch encouraged individuals to transcend conventional morality and create their own values. His works, such as "Thus Spoke Zarathustra" and "Beyond Good and Evil," explored themes of will to power and eternal recurrence, influencing existentialism and modern philosophy. Nietzsche's innovative ideas continue to provoke thought and spark debates in various disciplines.
