“ MENEDEMUS, Greek philosopher, and founder of the Eretrian school of thought, was born at Eretria about 350 and died between 278 and 275 B.C. Though of noble birth, he worked as builder and tentmaker until he was sent with a military expedition to Megara, where, according to Diogenes Laertius, he heard Plato and resolved to devote himself to philosophy. It is more likely that he heard one of Plato’s followers, inasmuch as Plato died when he was only four years old, if the above dates are correct. ”

“ In ethics, we learn from Plutarch (De virt. mor. 2) and from Cicero (Acad. ii. 42) that he regarded Virtue as one, by whatever name it be called, and maintained that it is intellectual. Cicero’s evidence is the less valuable in that he always assumed that Menedemus was a follower of the Megarians. ”
