Polemon (400–269 BCE)
Born 400 BCE, died 269 BCE.
Polemon of Athens (Ancient Greek: Πολέμων, gen.: Πολέμωνος; d. 270/269 BC) was an eminent Greek Platonist philosopher and Plato's third successor as scholarch (i.e., head of the Academy) from 314/313 to 270/269 BC. A pupil of Xenocrates, he believed that philosophy should be practiced rather than just studied, and he placed the highest good in living according to nature.
