The formula panta rhei (Ancient Greek: ÃÂìýÃÂñ á¿¥Ã栨Â, meaning "everything flows") is an aphorism which describes Heraclitus' doctrine. Plato attributes this teaching to Heraclitus in his dialogue Cratylus, but the formula first appears in the work of the late antique Neoplatonist Simplicius. This formulaic summary of Heraclitus' thought was already in use in Augustan times. Its Latin translation () can be found in the 15th book of Metamorphoses in the "Speech of Pythagoras", in which Ovid sets out the natural philosophical foundation of his Metamorphoses.
àìýÃÂñ ῥõῠis a formulaic summary of Heraclitus' thought, who flourished around 500BC. In his characterization of Heraclitus' cosmological theory, Plato has Socrates combine some of his best-known theorems: "", "everything moves and nothing stays" â with "all kinds of ancient wisdom, of course about Cronus and Rhea, which Homer had already said". He assumes that the name of the Titan, Rhea, can be traced back to the meaning of "to flow".
The phrase is first found in literal form in Simplicius (born 490 â 560), a late antique commentator on the writings of Aristotle.
The fact that the phrase in the flux doctrine is an interpretation of Heraclitus' statements is not inaccurate, but nonetheless abbreviated. It is supported by three so-called "flux fragments", in which Heraclitus compares being with a river:
Graham notes that only B12 has language which reflects other quotations from Heraclitus, and concludes that only B12 is genuine. Fragment 49a is in Attic Greek, not in Heraclitus' Ionic dialect, and B91[a] is "patently a paraphrase". Geoffrey Kirk and Miroslav Marcovich reach the same conclusion.
The flux doctrine is to be understood in the context of Heraclitus' doctrine of the unity of all things:
Plato's quote Pánta chorei kaì oudèn ménei is the most concise formulation of Heraclitus' theory of flux, which states: "Everything flows and nothing remains; there is only an eternal becoming and changing." Unlike Heraclitus himself, the focus here is on the aspect of becoming and passing away. In the tradition of the Platonic school, but also in numerous more recent interpretations (e.g. Hölderlin and Hegel), Heraclitus' teaching appears only as one of becoming and passing away. According to Nietzsche, it is essentially a concept of the "affirmation of passing away" (Bejahung des Vergehens).
In contrast, according to the theory of flux, the primary experience of the world lies in the continuous change of matter and form. It is a metaphor for the processuality of the world. Being is the becoming of the whole. Being is therefore not static, but is to be understood dynamically as eternal change. However, behind and at the same time in the incessant flux is unity: unity in multiplicity and multiplicity in unity. Karl-Martin Dietz nevertheless interprets the flux theory as Heraclitus' reference to the world of the unchangingly common.
Johann Wolfgang von Goethe referred directly to Heraclitus in the poem Dauer im Wechsel:Eternal change is also the subject of his poem Eins und Alles:
