Plutarch of Athens wrote commentaries on what Greek philosopher, whose writings constitute the first comprehensive system of Western philosophy?
Plutarch of Athens Plutarch of Athens (Greek: Πλούταρχος ὁ Ἀθηναῖος ; c. 350 – 430 AD) was a Greek philosopher and Neoplatonist who taught at Athens at the beginning of the 5th century. He reestablished the Platonic Academy there and became its leader. He wrote commentaries on Aristotle and Plato, emphasizing the doctrines which they had in common.
Callicles Callicles ( ; Greek: Καλλικλῆς ; c. 484 – late 5th century BCE) was an ancient Athenian political philosopher best remembered for his role in Plato’s dialogue "Gorgias", where he "presents himself as a no-holds-barred, bare-knuckled, clear-headed advocate of "Realpolitik". While he provides a counter-argument to Plato’s philosophical ideas, there is belief that he may be no more than a character created by Plato for the dialogue. Another idea proposed is that Callicles is a fragment of what Plato may be, had he not Socrates to guide him. He is the antithesis to Socrates.
