||Friedrich Nietzsche is a 19th century German philosopher. He began his career as a philologist. Due to illness he retired from active academic life as a philologist in the summer of 1879 and devoted himself fully to the writing of his philosophical works. Nietzsche is most famous for his word God is dead. While it is not clear whether this word implies atheism, agnosticism or depth-theism, it shows that theological, metaphysical and moral issues inform the work of Nietzsche. For a long time Nietzsche was considered a philosophical dilettante, a mystic or a poet-philosopher. This view has been significantly altered by Heidegger's Nietzsche lectures from 1936-44 which characterize him as a systematic, metaphysically-oriented philosopher. In the Anglo-American world works of scholars such as Arthur C. Danto and John Richardson have also shown that Nietzsche should be taken seriously as a philosopher. Aside from Nietzsche's metaphysics (which encompasses the concepts of will to power, eternal recurrence, Uebermensch and nihilism), the German philosopher provided an original interpretation and critique of Christian ethics and morality. This work is found in the two major works On The Genealogy Of Morals and Beyond Good And Evil. Throughout his work Nietzsche is in dialogue with the Western philosophical tradition, which he severely criticizes. True to the task of cultural physician he takes upon himself the difficult endeavour of becoming the bad conscience of Western civilization. His main philosophic interlocutors are the Platonic and Xenophonic Socrates, Plato, the Stoics, Kant, Hegel and Schopenhauer.
