Anniceris
Anniceris (; fl. 300 BC) was a Cyrenaic philosopher. He argued that pleasure is achieved through individual acts of gratification which are sought for the pleasure that they produce, but he also laid great emphasis on the love of family, country, friendship and gratitude, which provide pleasure even when they demand sacrifice. The Suda says he lived at the time of Alexander the Great (ruled 336–323 BC). The story that Anniceris ransomed Plato from Dionysius, tyrant of Syracuse for twenty minas, must refer to an earlier Anniceris, possibly the celebrated charioteer mentioned by Aelian.
