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.
Hegesias of Cyrene Hegesias (Greek: Ἡγησίας ; fl. 290 BC ) of Cyrene was a Cyrenaic philosopher, the Cyrenaics forming one of the earliest Socratic schools of philosophy. He argued that happiness is impossible to achieve, and that the goal of life was the avoidance of pain and sorrow. Conventional values such as wealth, poverty, freedom, and slavery are all indifferent and produce no more pleasure than pain. Cicero claims that Hegesias wrote a book called "Death by Starvation", which persuaded so many people that death is more desirable than life, that Hegesias was banned from teaching in Alexandria. It has been thought by some that Hegesias was influenced by Buddhist teachings.
