The life of Plato emerged from Laertius, writing in the 3rd century CE, 500 years after Plato's death. Laertius describes Plato as fighting in the Athenian army as a hoplite at Corinth and Tangara but also at Delium where he gained a prize for valour. But when the latter was fought, Plato (real name Aristocles) was about five years old. An astounding feat!This might simply be confusion with Socrates. Not all the Dialogues accorded to Plato may be his, and ascribed work has been lost. about 27 works are known to be definitively by Plato.
My own discussions on Plato suggest he had Socrates essentially authoritarian brief, but how can we really know? From this point, the works of other teachers (usually recorded by others) such as Jesus can be fruitfully challenged and parts of Muhammad's programmatic declarations.
