Friedrich Nietzsche (1844-1900) was a nineteenth-century German-born philosopher and classical philologist. He wrote critical texts on religion, morality, contemporary culture, philosophy, and science, using a distinctive German language style. In 1889 he exhibited symptoms of insanity and lived his remaining years in the care of his mother and sister. His ideas exercised a major influence on several prominent European philosophers, including Martin Heidegger, Albert Camus, and Jean-Paul Sartre.
