While some sources attribute to Simplicius the coining of the phrase πάντα ῥεῖ (panta rhei), meaning "everything flows/is in a state of flux", to characterize the concept in the philosophy of Heraclitus,[21] the essential phrasing "everything changes"[22] and variations on it, in contexts where Heraclitus's thought is being alluded to, was current in both Plato and Aristotle's writings.[23][24] "Simplicius": On Aristotle, On the Soul 3.1-5, translated by Henry J. ./cache/en-wikipedia-org-4015.html ./txt/en-wikipedia-org-4015.txt
