In at least Plato's time, the school did not have any particular doctrine to teach; rather, Plato (and probably other associates of his) posed problems to be studied and solved by the others.
I Platons periode havde skolen ikke nogen speciel lære der undervistes i; det fungerede snarere sådan at Platon (og formentlig også hans kollegaer) opstillede problemstillinger, der skulle studeres, diskuteres og løses af de andre.
