Stilpo (Stilpon), Greek philosopher of the Megarian school, was a contemporary of Theophrastus and Crates .
Intellectually in agreement with the Megarian dialectic, he followed the practical ethics of the Cynics both in theory and in practice. He extolled the Cynic airadda (loosely, self-control) as the principal virtue. Cicero (De fato, 5) describes him as a man of the highest character. Suidas attributes twenty dialogues to him, but of these no fragments remain.
Among his followers were Menedemus and Asclepiades , the leaders of the Eretrian school of philosophy. Seneca (Epistle 9) shows how closely allied Stilpo was to the Stoics.
