PLATO'S ARGUMENT
The ancient Greek philosopher, who was a student of Socrates, and a teacher of Aristotle, was the founding father of the Academy, and best known as the author of philosophical works of unparalleled influence.
Building on the demonstration by Socrates that those regarded as experts in ethical matters did not have the understanding necessary for a good human life, Plato introduced the idea that their mistakes were due to their not engaging properly with a class of entities he called forms, which were Justice, Beauty, and Equality.
