The Eretrian school of philosophy was originally the School of Elis, where it had been founded by Phaedo of Elis; it was later transferred to Eretria by his pupil Menedemus.
It died out after the time of Menedemus (3rd century BC), and, consequently, very little is known about its tenets.
Menedemus was a pupil of Stilpo at Megara before becoming a pupil of Phaedo; in later times, the views of his school were often linked with those of the Megarian school.
Menedemus' friend and colleague in the Eretrian school was Asclepiades of Phlius.
