full_context: Document 1: Friedrich Nietzsche: 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.
Document 2: God Is Dead?: "God Is Dead?" is a song by heavy metal band Black Sabbath featured on the album "13". It is the first single from the album, and the first with Ozzy Osbourne since 1998's "Psycho Man" and "Selling My Soul" from "Reunion". The song was released via an MP3 download on Amazon. It was also available as a free download to those who pre-ordered the full album on iTunes. The song in its entirety was posted on the official YouTube channel in promotion of this. Both the song title and figure on the single's cover, by Heather Cassils, are a reference to Friedrich Nietzsche, a German philosopher who is famous for saying that "God is dead. God remains dead. And we have killed him. How shall we comfort ourselves, the murderers of all murderers?".

Document 4: The Phenomenology of Spirit: Phänomenologie des Geistes (1807) is Georg Wilhelm Friedrich Hegel's most widely discussed philosophical work. Hegel's first book, it describes the three-stage dialectical life of Spirit. The title can be translated as either The Phenomenology of Spirit or The Phenomenology of Mind, because the German word "Geist" has both meanings. The book's working title, which also appeared in the first edition, was "Science of the Experience of Consciousness". On its initial publication (see cover image on right), it was identified as Part One of a projected "System of Science", of which the "Science of Logic" was the second part. A smaller work, titled "Philosophy of Spirit" (also translated as "Philosophy of Mind"), appears in Hegel's "Encyclopedia of the Philosophical Sciences", and recounts in briefer and somewhat altered form the major themes of the original "Phenomenology".
Document 5: Thus Spoke Zarathustra: Thus Spoke Zarathustra: A Book for All and None (German: "Also sprach Zarathustra: Ein Buch für Alle und Keinen" , also translated as Thus Spake Zarathustra) is a philosophical novel by German philosopher Friedrich Nietzsche, composed in four parts between 1883 and 1885 and published between 1883 and 1891. Much of the work deals with ideas such as the "eternal recurrence of the same", the parable on the "death of God", and the "prophecy" of the "Übermensch", which were first introduced in "The Gay Science".
Document 6: Beyond Good and Evil: Beyond Good and Evil: Prelude to a Philosophy of the Future (German: "Jenseits von Gut und Böse: Vorspiel einer Philosophie der Zukunft" ) is a book by philosopher Friedrich Nietzsche that expands the ideas of his previous work, "Thus Spoke Zarathustra", with a more critical and polemical approach. It was first published in 1886.
Document 7: Faith in the Earth: "Faith in the Earth" is the German philosopher Friedrich Nietzsche's mytho-poetic formulation of his re-valued conception of our possible experience of divinity as contained in his book "Thus Spoke Zarathustra". Although not traditionally religious in the sense of positing the existence of a divine entity or entities, Nietzsche's way of thinking is just as far removed from atheistic materialism as it is from theistic spiritualism. Closely related to the tradition of negative theology, Nietzsche confesses his own oblique form of belief, from his early poem "Dem unbekannten Gott," to the deep meaning of the "Dionysian Dithyrambs". Put simply, we speak least erroneously when we observe a strict adherence to the use of the word "divine" as a verb, and not a noun. To divine is to orient without teleology: we can divine the way without knowing where we are going, while yet still being oriented. Nietzsche's name for this uncanny experience is "amor fati," and it names not things, but a way things can change.

Document 10: God is dead: "God is dead" (German:    ; also known as the death of God) is a widely quoted statement by German philosopher Friedrich Nietzsche. It first appears in Nietzsche's 1882 collection "The Gay Science" ("Die fröhliche Wissenschaft ", also translated as "The Joyful Pursuit of Knowledge and Understanding") However, it is most famously associated with Nietzsche's classic work "Thus Spoke Zarathustra" ("Also sprach Zarathustra "), which is most responsible for making the phrase popular.

The oil painting "Also Sprach Zarathustra" series was exhibited several times — including the exhibition at the Institute of Philosophy of the Russian Academy of Sciences in 1997 and at the First Moscow Biennale of contemporary art in 2005.
Document 15: Influence and reception of Friedrich Nietzsche: Friedrich Nietzsche's influence and reception varied widely and may be roughly divided into various chronological periods. Reactions were anything but uniform, and proponents of various ideologies attempted to appropriate his work quite early. By 1937, this led Georges Bataille to argue against any "instrumentalization" of Nietzsche's thought, paradoxically as a social-anarchist himself; Bataille, the passionate, determined socialist and anti-fascist, believed that any simple-minded interpretation or unified ideological characterization of Nietzsche's work, granting predominance to any particular aspect, failed to do justice to the body of his work as a whole.
