Go read Plato's Republic and you'll see what I mean. It does not describe any sort of a Republic, but rather an antlike, rigidly-stratified society based on castes fixed at birth with no movement between castes possible. It is a nightmare totalitarian society straight out of George Orwell.
Plato was an asshole, in my book. Had Socrates lived to see what Plato turned into, he would have disowned and rejected him entirely.
