After reading this PDF document which contains excerpts from Book V and Book VI from Plato’s Republic, can you tell me what the main point or argument that Socrates is trying to convince Glaucon of from these choices :
A. That those already in power in Ancient Athens will not welcome Socrates’ claim that philosophers should be kings.
B. That true beauty is a concept or idea, and not a mere characteristic of beautiful physical things and people.
C.That in order for human happiness to be possible, philosophers should rule as kings, for those with philosophical natures are best suited to political rule.
