Friedrich Nietzsche (1844–1900), German philosopher, philologist, and poet, was one of the most iconoclastic thinkers of the modern era. Appointed professor of classical philology at Basel at age 24, he later resigned due to poor health and spent years writing across Europe before a mental collapse in 1889.
Nietzsche declared 'God is dead'—not as simple atheism but as a diagnosis of the collapse of Western value systems. He proposed the Übermensch, the will to power, and eternal recurrence, calling on humanity to overcome nihilism and courageously create new values. His major works include Thus Spoke Zarathustra, Beyond Good and Evil, and On the Genealogy of Morals.
Nietzsche profoundly influenced existentialism, postmodernism, psychoanalysis, and the arts. Though his ideas were misappropriated by the Nazis, contemporary scholarship has clarified his philosophy, recognizing him as a pioneer of modernity critique and individual liberation.
