Define Nietzsche.

Friedrich Nietzsche (1844-1900) was a German philosopher known for his radical and influential ideas that challenged traditional moral values, religion, and philosophical conventions of his time. Nietzsche's philosophy is characterized by a sharp critique of Christianity and the concept of objective truth, advocating instead for a "revaluation of all values" based on individual creativity, will to power, and self-overcoming.

Central to Nietzsche's thought is the idea of the "Übermensch" or "Overman," representing individuals who transcend conventional morality and societal norms to create their own values. He famously declared that "God is dead," suggesting the decline of religious authority and the need to embrace human agency and creativity.

Nietzsche's philosophy is marked by his rejection of traditional metaphysics and his exploration of the human condition through psychological and existential lenses. He argued that human existence is characterized by struggle and suffering, but viewed this as an opportunity for self-actualization and personal growth.

Key concepts in Nietzsche's philosophy include the "will to power," which signifies the fundamental driving force behind human behavior, and "eternal recurrence," a thought experiment challenging individuals to live their lives as if they would repeat infinitely.

Nietzsche's writings have had a profound impact on existentialism, postmodernism, and various strands of contemporary philosophy, literature, and cultural criticism. Despite his controversial and often misunderstood ideas, Nietzsche's work continues to provoke thought and debate on issues of morality, human nature, and the pursuit of individual greatness.
