=78.= In becoming in turn a listener to Polemo, Zeno, we may imagine, entered a new world. He left behind the rough manners, the stinging retorts, and the narrow culture of the Cynics and Eristics[47], to sit with other intelligent students[48] at the feet of a man of cultured manners[49] and wide reading, who to a love for Homer and Sophocles[50] had, we must suppose, added an intimate knowledge of the works of Plato and Aristotle, was himself a great writer[51], and yet consistently taught that not learning, but a natural and healthy life was the end to be attained. That Zeno profited much from his studies under Polemo we may conjecture from Polemo’s good-natured complaint, ‘I see well what you are after: you break down my garden wall and steal my teaching, which you dress in Phoenician clothes[52].’ From this time it became a conventional complaint that Stoic doctrine was stolen from that of the Academics: yet the sharp conflict between the two schools shews that this cannot apply to essentials. But in two important matters at least Zeno must have been indebted to Academic teaching. This school had elaborated the doctrine of Anaxagoras, which so attracted Socrates, that the world began with the working of mind upon unordered matter. So too, according to all our authorities, Zeno taught that there are two beginnings, the active which is identified with the deity or Logos, and the passive which is inert matter, or substance without quality[53]. This doctrine appears to pledge Zeno to a dualistic view of the universe. [Sidenote: ‘Soul is body.’] =79.= On the other hand the Platonic teaching on the soul was reversed by Zeno. He denied the opposition between soul and body. ‘Soul is Breath[54],’ he taught, and ‘soul is body[55].’ With Plato’s threefold division of the soul he would have nothing to do; rather he maintained that the soul has eight parts[56], each displaying itself in a distinct power or capacity, whilst all of them are qualities or operations of one soul in various relations[57]. In this part of his philosophy Zeno appears as a strong monist, and his debt to the Platonists is necessarily restricted to details. [Sidenote: Zeno studies Heraclitus.]
