W;hat ancient Greek philosopher died in 322 BC had testimony used in "On The Nature of Man"?
On the Nature of Man On the Nature of Man is a work in the Hippocratic Corpus. "On the Nature of Man" is attributed to Polybus, the son in law and disciple of Hippocrates, through a testimony from Aristotle's "History of Animals". However, as with the many other works of the Hippocratic Corpus, the authorship is regarded as dubious in origin.
Aristo of Chios Aristo of Chios (Greek: Ἀρίστων ὁ Χῖος "Ariston ho Chios"; fl. c. 260 BC) was a Stoic philosopher and colleague of Zeno of Citium. He outlined a system of Stoic philosophy that was, in many ways, closer to earlier Cynic philosophy. He rejected the logical and physical sides of philosophy endorsed by Zeno and emphasized ethics. Although agreeing with Zeno that Virtue was the supreme good, he rejected the idea that morally indifferent things such as health and wealth could be ranked according to whether they are naturally preferred. An important philosopher in his day, his views were eventually marginalized by Zeno's successors.
