Zeno, the founder of Stoicism, was born in Cyprus at some date unknown, but his life may be said roughly to be between the years 350 and 250 B.C. Cyprus has been from time immemorial a meeting-place of the East and West, and although we cannot grant any importance to a possible strain of Phoenician blood in him (for the Phœnicians were no philosophers), yet it is quite likely that through Asia Minor he may have come in touch with the Far East. He studied under the cynic Crates, but he did not neglect other philosophical systems. After many years' study he opened his own school in a colonnade in Athens called the Painted Porch, or Stoa, which gave the Stoics their name. Next to Zeno, the School of the Porch owes most to Chrysippus (280--207 b.c.), who organised Stoicism into a system. Of him it was said, 'But for Chrysippus, there had been no Porch.' The Stoics regarded speculation as a means to an end and that end was, as Zeno put it, to live consistently (ὁμολογουμένος ζῆν), or as it was later explained, to live in conformity with nature (ὁμολογουμένος τῇ φύσει ζῆν). This conforming of the life to nature was the Stoic idea of Virtue. This dictum might easily be taken to mean that virtue consists in yielding to each natural impulse; but that was very far from the Stoic meaning. In order to live in accord with nature, it is necessary to know what nature is; and to this end a threefold division of philosophy is made—into _Physics_, dealing with the universe and its laws, the problems of divine government and teleology; _Logic_, which trains the mind to discern true from false; and _Ethics_, which applies the knowledge thus gained and tested to practical life. The Stoic system of physics was materialism with an infusion of pantheism. In contradiction to Plato's view that the Ideas, or Prototypes, of phenomena alone really exist, the Stoics held that material objects alone existed; but immanent in the material universe was a spiritual force which acted through them, manifesting itself under many forms, as fire, æther, spirit, soul, reason, the ruling principle. The universe, then, is God, of whom the popular gods are manifestations; while legends and myths are allegorical. The soul of man is thus an emanation from the godhead, into whom it will eventually be re-absorbed. The divine ruling principle makes all things work together for good, but for the good of the whole. The highest good of man is consciously to work with God for the common good, and this is the sense in which the Stoic tried to live in accord with nature. In the individual it is virtue alone which enables him to do this; as Providence rules the universe, so virtue in the soul must rule man.
