Eternal return in the context of "Nietzsche"

Friedrich Wilhelm Nietzsche (15 October 1844 – 25 August 1900) was a German philosopher. He began his career as a classical philologist, turning to philosophy early in his academic career. In 1869, aged 24, Nietzsche became the youngest professor to hold the Chair of Classical Philology at the University of Basel. Plagued by health problems for most of his life, he resigned from the university in 1879, and in the following decade he completed much of his core writing. In 1889, aged 44, he suffered a collapse and thereafter a complete loss of his mental faculties, with paralysis and vascular dementia, living his remaining 11 years under the care of his family until his death. His works and his philosophy have fostered not only extensive scholarship but also much popular interest.

Nietzsche's work encompasses philosophical polemics, poetry, cultural criticism and fiction, while displaying a fondness for aphorisms and irony. Prominent elements of his philosophy include his radical critique of truth in favour of perspectivism; a genealogical critique of religion and Christian morality and a related theory of master–slave morality; the aesthetic affirmation of life in response to both the "death of God" and the profound crisis of nihilism; the notion of Apollonian and Dionysian forces; and a characterisation 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 his 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, music, religion, tragedy, culture and science, and drew inspiration from Hebrew literature, Indian literature and Greek tragedy, as well as figures such as Zoroaster, Arthur Schopenhauer, Ralph Waldo Emerson, Richard Wagner, Fyodor Dostoevsky and Johann Wolfgang von Goethe.

Friedrich Nietzsche (1844–1900) developed his philosophy during the late 19th century. He owed the awakening of his philosophical interest to reading Arthur Schopenhauer's Die Welt als Wille und Vorstellung (The World as Will and Representation, 1819, revised 1844) and said that Schopenhauer was one of the few thinkers that he respected, dedicating to him his essay Schopenhauer als Erzieher (Schopenhauer as Educator), published in 1874 as one of his Untimely Meditations.

Since the dawn of the 20th century, the philosophy of Nietzsche has had great intellectual and political influence around the world. Nietzsche applied himself to such topics as morality, religion, epistemology, poetry, ontology, and social criticism. Because of Nietzsche's evocative style and his often outrageous claims, his philosophy generates passionate reactions running from love to disgust. Nietzsche noted in his autobiographical Ecce Homo that his philosophy developed and evolved over time, so interpreters have found it difficult to relate concepts central to one work to those central to another, for example, the thought of the eternal recurrence features heavily in Also sprach Zarathustra (Thus Spoke Zarathustra), but is almost entirely absent from his next book, Beyond Good and Evil. Added to this challenge is the fact that Nietzsche did not seem concerned to develop his thought into a system, even going so far as to disparage the attempt in Beyond Good and Evil.

Anti-Oedipus: Capitalism and Schizophrenia (French: Capitalisme et schizophrénie. L'anti-Œdipe) is a 1972 book by French authors Gilles Deleuze and Félix Guattari, the former a philosopher and the latter a psychoanalyst. It is the first volume of their collaborative work Capitalism and Schizophrenia, the second being A Thousand Plateaus (1980).

In the book, Deleuze and Guattari developed the concepts and theories in schizoanalysis, a loose critical practice initiated from the standpoint of schizophrenia and psychosis as well as from the social progress that capitalism has spurred. They refer to psychoanalysis, economics, the creative arts, literature, anthropology and history in engagement with these concepts. Contrary to contemporary French uses of the ideas of Sigmund Freud, they outlined a "materialist psychiatry" modeled on the unconscious regarded as an aggregate of productive processes of desire, incorporating their concept of desiring-production which interrelates desiring-machines and bodies without organs, and repurpose Karl Marx's historical materialism to detail their different organizations of social production, "recording surfaces", coding, territorialization and the act of "inscription". Friedrich Nietzsche's ideas of the will to power and eternal recurrence also have roles in how Deleuze and Guattari describe schizophrenia; the book extends from much of Deleuze's prior thinking in Difference and Repetition and The Logic of Sense that utilized Nietzsche's ideas to explore a radical conception of becoming.

The "eternal return" is an idea for interpreting religious behavior proposed by the historian Mircea Eliade; it is the belief that through ritual practices (sometimes implicitly, but often explicitly) one is able to merge with or return to the "mythical age"—the actual time of one's myths. It should be distinguished from the philosophical concept of eternal return.

The term Great Year has multiple meanings. In scientific astronomy, it refers to the time required for the equinoxes to complete one full cycle around the ecliptic, a period of approximately 25,800 years. According to Ptolemy, his teacher Hipparchus discovered this phenomenon by comparing the position of the vernal equinox against the fixed stars, noting that it shifts westward by about one degree every 72 years. This means that a full cycle through all the zodiac constellations takes roughly 25,920 years. In the heliocentric model, this precession can be visualized as the Earth’s rotational axis slowly tracing a circular path around the normal to the plane of the ecliptic. Currently, Earth's axis points close to Polaris, the North Star, but due to precession, this alignment is temporary and will shift over time, returning only after one complete Great Year has passed.

By extension, the term "Great Year" can be used for any concept of eternal return in the world's mythologies or philosophies. Historian Otto Neugebauer writes:
