Plato

428–348 BC

Platonic·Graecia

Student of Socrates, teacher of Aristotle. Plato's philosophy rests on the distinction between the world of appearances and the world of Forms — eternal, perfect patterns of which physical things are imperfect copies. His theory of anamnesis holds that the soul, immortal and pre-existing, already knows all truth. Learning is not acquisition but recollection.
