Friedrich Wilhelm Nietzsche (15 October 1844 – 25 August 1900) was a German philosopher, cultural critic, poet, philologist, and Latin and Greek scholar whose work has exerted a profound influence on Western philosophy and modern intellectual history. He began his career as a classical philologist before turning to philosophy. He became the youngest ever to hold the Chair of Classical Philology at the University of Basel in 1869, at the age of 24. He resigned in 1879 due to health problems that plagued him most of his life, and he completed much of his core writing in the following decade. In 1889, at age 44, he suffered a collapse and a complete loss of his mental faculties. He lived his remaining years in the care of his mother until her death in 1897, and then with his sister Elisabeth Förster-Nietzsche, and died in 1900.
Nietzsche's body of work touched widely on art, philology, history, religion, tragedy, culture, and science, and drew early inspiration from figures such as Schopenhauer, Wagner, and Goethe. His writing spans philosophical polemics, poetry, cultural criticism, and fiction while displaying a fondness for aphorism and irony. Some prominent elements of his philosophy include his radical critique of truth in favor of perspectivism; his genealogical critique of religion and Christian morality, and his related theory of master–slave morality; his aesthetic affirmation of existence in response to the "death of God" and the profound crisis of nihilism; his notion of the Apollonian and Dionysian; and his characterization of the human subject as the expression of competing wills, collectively understood as the will to power. In his later work, he developed influential concepts such as the Übermensch and the doctrine of eternal return, and became increasingly preoccupied with the creative powers of the individual to overcome social, cultural, and moral contexts in pursuit of new values and aesthetic health.
After his death, Elisabeth Förster-Nietzsche became the curator and editor of her brother's manuscripts, reworking Nietzsche's unpublished writings to fit her own German nationalist ideology while often contradicting or obfuscating his stated opinions, which were explicitly opposed to antisemitism and nationalism. Through her published editions, Nietzsche's work became associated with fascism and Nazism; 20th century scholars contested this interpretation of his work and corrected editions of his writings were soon made available. His thought enjoyed renewed popularity in the 1960s, and his ideas have since had a profound impact on 20th and early-21st century thinkers across philosophy—especially in schools of continental philosophy such as existentialism, postmodernism, and post-structuralism—as well as art, literature, psychology, politics, and popular culture.
there was a revival of Nietzsche's philosophical writings thanks to exhaustive translations and analyses by Walter Kaufmann and R. J. Hollingdale. Others, well known philosophers in their own right, wrote commentaries on Nietzsche's philosophy, including Martin Heidegger, who produced a four-volume study, and Lev Shestov, who wrote a book called Dostoyevski, Tolstoy and Nietzsche where he portrays Nietzsche and Dostoyevski as the "thinkers of tragedy". Georg Simmel compares Nietzsche's importance to ethics to that of Copernicus for cosmology. Sociologist Ferdinand Tönnies read Nietzsche avidly from his early life, and later frequently discussed many of his concepts in his own works. Nietzsche has influenced philosophers such as Heidegger, Jean-Paul Sartre, Oswald Spengler, George Grant, Emil Cioran, Albert Camus, Ayn Rand, Jacques Derrida, Leo Strauss, Max Scheler, Michel Foucault and Bernard Williams. Camus described Nietzsche as "the only artist to have derived the extreme consequences of an aesthetics of the absurd". Paul Ricœur called Nietzsche one of the masters of the "school of suspicion", alongside Karl Marx and Sigmund Freud. Carl Jung was also influenced by Nietzsche. In Memories, Dreams, Reflections, a biography transcribed by his secretary, he cites Nietzsche as a large influence. Aspects of Nietzsche's philosophy, especially his ideas of the self and his relation to society, also run through much of late-twentieth and early twenty-first century thought. His deepening of the romantic-heroic tradition of the nineteenth century, for example, as expressed in the ideal of the "grand striver" appears in the work of thinkers from Cornelius Castoriadis to Roberto Mangabeira Unger. For Nietzsche this grand striver overcomes obstacles, engages in epic struggles, pursues new goals, embraces recurrent novelty, and transcends existing structures and contexts. No social or cultural construct can contain this idealized individual.
