Aristippus the Younger
Aristippus the Younger (; Ancient Greek: Ἀρίστιππος), of Cyrene, was a Cyrenaic philosopher in the second half of the 4th century BC. He was the grandson of Aristippus of Cyrene, the founder of the school. According to Diogenes Laërtius, he received the nickname "Mother-taught" (metrodidaktos). because he learned philosophy from his mother, Arete of Cyrene, who was the daughter of the elder Aristippus. Diogenes lists Theodorus the Atheist as one of his students.
