The concept of eternal return posits that time operates in an infinite loop, with all events perpetually repeating. This idea has roots in ancient Greek philosophy, notably with Empedocles and the Stoics, who believed the universe undergoes cycles of destruction and rebirth. Early Eastern philosophies, such as Hinduism and Buddhism, also feature cyclical cosmologies and the transmigration of souls, echoing a similar notion of endless recurrence.

Friedrich Nietzsche significantly revived and explored this concept in the 19th century, presenting it as a profound thought experiment in "The Gay Science" and "Thus Spoke Zarathustra." While Nietzsche's personal belief in its literal truth remains debated, his formulation challenged individuals to confront the possibility of living their lives over and over. The idea has since been reinterpreted by various thinkers, including esotericists like P.D. Ouspensky, who considered the potential to break free from these cycles.

In classical antiquity, the idea of eternal return was a prominent philosophical concept. Thinkers like Empedocles and the Stoic school, founded by Zeno of Citium, explored this notion. The Stoics envisioned the cosmos undergoing periodic destruction by fire (ekpyrosis) followed by rebirth (palingenesis), with each cycle precisely mirroring the last. This was potentially influenced by Pythagorean ideas, which suggested that events recur after specific periods, and that "nothing was entirely new." Plato's concept of the Great Year, where celestial bodies realign, also offered a framework for such cyclical thinking. However, this doctrine faced criticism from Christian writers like Augustine, who argued it contradicted free will and the possibility of salvation, contributing to its decline with the spread of Christianity.

The notion of cyclical time and recurring events finds deep roots in Eastern philosophies, particularly within Indian cosmology. Hinduism features the concept of a Kalpa, a vast period after which Brahma recreates the universe, and the central doctrine of reincarnation, or transmigration of the soul. Similarly, Buddhism presents the Kalachakra, or "Wheel of Time," representing an unending cycle of birth, life, and death from which liberation is sought. The development of the concept of saṃsāra in early Upanishads, detailing cyclic change through reincarnation, bears significant resemblance to later formulations of eternal return.

Friedrich Nietzsche brought the concept of eternal return, or "Ewige Wiederkunft," to the forefront of modern philosophy in the 19th century. While acknowledging precursors and influences from ancient thought and contemporary philosophers, Nietzsche described his own encounter with the idea as a sudden revelation. He first presented it as a challenging thought experiment in "The Gay Science," posing the question of how one would react to the knowledge that their entire life, with all its joys and pains, would repeat eternally. In "Thus Spoke Zarathustra," Nietzsche further explored this idea, with his protagonist grappling with and ultimately seeking to affirm the thought of eternal recurrence. The precise interpretation of Nietzsche's stance on whether he believed in its literal truth remains a subject of ongoing philosophical discussion.

Following Nietzsche, the concept of eternal return was taken up and reinterpreted by subsequent thinkers. Writers such as the Russian esotericist P.D. Ouspensky engaged with the idea, proposing that it might be possible to transcend or break the cycle of recurrence. This suggests a development of the concept beyond Nietzsche's original formulation, moving towards possibilities of liberation or transformation within the cyclical framework. The ongoing speculation about Nietzsche's intent and the interpretations by later figures highlight the concept's enduring philosophical and esoteric appeal.

“What if some day or night a demon were to steal after you into your loneliest loneliness, and say to you, "This life as you now live it and have lived it, you will have to live once more and innumerable times more; and there will be nothing new in it, but every pain and every joy and every thought and sigh and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence" ... Would you not throw yourself down and gnash your teeth and curse the demon who spoke thus? Or have you once experienced a tremendous moment when you would have answered him: "You are a god and never have I heard anything more divine."”

“What is that which hath been? It is that which shall be. And what is that which is done? It is that which shall be done: and there is no new thing under the sun. Who can speak and say, See, this is new? It hath been already of old time, which was before us.”
