STOICS AND EPICUREANS.--In the fourth and even the third century, philosophy spoke to mankind through two principal schools: those of the Stoics and of the Epicureans. The chief representatives of the Stoics were Zeno and Cleanthes. Chrysippus taught an austere morality which may be summed up in these words: "Abstain and endure." The Epicureans, whose chief representatives were Epicurus and Aristippus, taught, when all was taken into account, the same morality but starting from a different principle, which was that happiness must be sought, and in pursuance of this principle they advised less austerity, even in their precepts. Although these are schools of philosophy, yet they must be taken into account here because each of them has exercised much influence over writers, the first on Seneca and much later on Corneille; the second on Lucretius and Horace; both sometimes on the same man, one example being Montaigne. After Alexander, intellectual Greece extended and enlarged itself so that Instead of having one centre, Athens, it possessed five or six: Athens, Alexandria, Antioch, Pergamos, Syracuse. This was an admirable literary efflorescence; the geniuses were less stupendous but the talents were innumerable. In the cities named, and in others, history, rhetoric, geography, philosophy, history of philosophy, philology, were taught with ardour and learnt with enthusiasm; the literary soil was rich and it was assiduously cultivated. ALEXANDRINE LITERATURE.--From this soil rose a fresh literature--more erudite, less spontaneous, less rich in popular vigour, yet very interesting. This is the literature known as _Alexandrine_. With this literature first appeared the _romance_, unknown to the ancients. The historical romance began with Hecataeus of Abdera, the philosophical romance with Evemerus of Messenia, who pretended to have found an ancient inscription proving that the gods of ancient Greece were old-time kings of the land deified after death, an ingenious invention from which was to come a whole school of criticism of ancient mythology.
