“He who fights with monsters should be careful lest he thereby become a monster.
And if thou gaze long into an abyss, the abyss will also gaze into thee.” – Friedrich Nietzsche
Friedrich Wilhelm Nietzsche (October 1844 – 25 August 1900) was a German philosopher, cultural critic, composer, poet, writer, and philologist whose work has exerted a profound influence on modern intellectual history. He began his career as a classical philologist before turning to philosophy. He became the youngest person ever to hold the Chair of Classical Philology at the University of Basel in 1869 at the age of 24. Nietzsche resigned in 1879 due to health problems that plagued him most of his life; he completed much of his core writing in the following decade. In 1889, at age 44, he suffered a collapse and afterward 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. Nietzsche died in 1900.
Nietzsche’s writing spans philosophical polemics, poetry, cultural criticism, and fiction while displaying a fondness for aphorism and irony. Prominent elements of his philosophy include his radical critique of truth in favor of perspectivism; a genealogical critique of religion and Christian morality and related theory of master–slave morality; the aesthetic affirmation of existence in response to the “death of God” and the profound crisis of nihilism; the notion of Apollonian and Dionysian forces; and a characterization of the human subject as the expression of competing wills, collectively understood as the will to power. He also developed influential concepts such as the Übermensch and the doctrine of eternal return. In his later work, he became increasingly preoccupied with the creative powers of the individual to overcome cultural and moral mores in pursuit of new values and aesthetic health. His body of work touched a wide range of topics, including art, philology, history, religion, tragedy, culture, and science, and drew early inspiration from figures such as philosopher Arthur Schopenhauer, composer Richard Wagner, and writer Johann Wolfgang von Goethe. – from en.wikipedia.org/wiki/Friedrich_Nietzsche
