It is uncertain precisely which doctrines ascribed to the Cyrenaic school were formulated by Aristippus. Diogenes Laërtius, based on the authority of Sotion and Panaetius, provided a long list of books said to have been written by Aristippus. However, Diogenes also wrote that Sosicrates had stated that Aristippus had written nothing. Among Aristippus' pupils was his daughter, Arete of Cyrene, who passed on his teachings to her own son Aristippus the Younger. It was he, according to Aristocles, who turned the teachings of his grandfather into a comprehensive system. At the least, however, it can be said that the foundations of Cyrenaic philosophy were ideas originated by the elder Aristippus.
