=72.= The members of the Peripatetic school founded by Aristotle are of less importance to us. The Romans found little difference between their teaching and that of the earlier Academy. Cicero mentions that the Stoic Panaetius was a keen student of two of the pupils of Aristotle, THEOPHRASTUS (his successor as head of the Peripatetic school) and DICAEARCHUS[19]; amongst later teachers in whose views he is interested he names HIERONYMUS, who held that the supreme good was freedom from pain[20]; CALLIPHO, who combined virtue with pleasure, and DIODORUS who combined it with freedom from pain[21]; and amongst his contemporaries STASEAS of Naples, who stated the same doctrines in a slightly different form[22], and CRATIPPUS, whom he selected as a teacher for his own son[23]. It was a common complaint of these teachers that the Stoics had stolen their doctrines wholesale, and (as is the way with thieves) had altered the names only[24]. All these writers however agree in denying the doctrine which Zeno accepted from the Cynics that ‘virtue is sufficient for happiness,’ and lay stress upon the supply of external goods (χορηγία) as needed to admit of the active exercise of virtue. They were diligent students of the written works of their founder, and thus opened the way for the work of erudition and interpretation which found its centre in Alexandria in a later period. [Sidenote: Zeno.] =73.= Amidst the conflict of these schools ZENO grew up. Born in Citium on the island of Cyprus in 336 B.C., in the same year in which Alexander became king of Macedon, he heard as a boy of the Greek conquest of the East, and was only 13 years of age when its course was checked by the death of Alexander. Of the town of Citium the inhabitants were partly Greek, partly Phoenician; and Zeno, whether or not he was of Phoenician blood, certainly derived from his environment something of the character of the enterprising and much-travelled Phoenician nation, and imparted this trait to the school which he founded. He was nicknamed by his contemporaries ‘the Phoenician,’ and the title clung to his followers[25]. His father was a merchant of purple, and often travelled in the one direction to Tyre and Sidon, in the other as far as Athens, whence he brought back a number of ‘Socratic books,’ which were eagerly read by the young Zeno, and in time attracted him to the famous Greek city[26]. We may presume that when he first came to Athens he intended to carry further his studies without abandoning his calling; but when news reached him of the wreck of the ship which carried all his goods, he welcomed it as a call to devote himself entirely to philosophy[27]. His first step in Athens was to seek out the man who best represented the character of Socrates, as represented in Xenophon’s Memoirs; and it is said that a bookseller accordingly pointed him to CRATES of Thebes[28], the pupil and (it would seem) the successor of Diogenes as acknowledged head of the Cynic school.
