Plutarch of Athens wrote commentaries on what Greek philosopher, whose writings constitute the first comprehensive system of Western philosophy?
Aristotle Aristotle ( ; Greek: Ἀριστοτέλης , , "Aristotélēs"; 384–322 BC) was an ancient Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, whereafter Proxenus of Atarneus became his guardian. At seventeen or eighteen years of age, he joined Plato's Academy in Athens and remained there until the age of thirty-seven (c. 347 BC). His writings cover many subjects – including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhetoric, linguistics, politics and government – and constitute the first comprehensive system of Western philosophy. Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored Alexander the Great beginning in 343 BC.
Hermias (apologist) Hermias ( ; sometimes Hermias Philosophus or Hermias the Philosopher; Greek: Ἑρμείας ) was an obscure Christian Apologist, presumed to have lived in 3rd century. Nothing is known of him, except his name. He wrote a "Derision of gentile philosophers" ("Diasyrmos ton Exo Philosophon"), a short parody on Greek philosophy themes (the nature of the body, the soul, the world). From Paul's statement in the First Epistle to the Corinthians that "all worldly knowledge is foolishness to God" he affirms that all philosophical doctrines come from the apostasy of the angels and therefore wrong and laughable. Hermias relies rather on cynical and skeptical culture critique and on philosophical biographies and anedoctes than in their real writings if he had ever read them.
