Aristippus

Aristippus of Cyrene lived circa 435 to circa 356 BCE and was a hedonistic Greek philosopher and the founder of the Cyrenaic school of philosophy; a pupil of Socrates, he adopted a different philosophical outlook, teaching that the goal of life was to seek pleasure by adapting circumstances to oneself and by maintaining proper control over both adversity and prosperity, a view that pleasure is the only good later called ethical hedonism, which brought him backlash from Socrates and many of his fellow pupils. His most famous phrase, reflecting his hedonistic beliefs, was I possess, I am not possessed; despite having two sons, he identified his daughter Arete as the intellectual heiress of his work, and the systematization of his teaching into the Cyrenaic school of philosophy was carried out by Arete and her son Aristippus the Younger, his grandson, during his later years and after his death, with some indication that Aristippus himself has since been conflated with that grandson.
