Later on we see the philosophy of the Stoics pass over to the Romans, that is to say, it became the philosophy of many Romans, though this philosophy did not gain anything as a science by so doing. On the contrary, as in the case of Seneca and the later Stoics, in Epictetus or Antoninus, all speculative interest was really lost, and a rhetorical and hortatory disposition shown, of which mention cannot be made in a history of Philosophy any more than of our sermons. Epictetus of Hierapolis in Phrygia, born at the end of the first century after Christ, was first of all the slave of Epaphroditus, who, however, freed him, after which he betook himself to Rome. When Domitian banished the philosophers, poisoners and astrologers from Rome (94 A.D.), Epictetus went to Nicopolis, in Epirus, and taught there publicly. From his lectures Arrian compiled the voluminous _Dissertationes Epicteteæ_, which we still possess, and also the manual ἐγχειρίδιον of Stoicism.[126] We still have the Meditations εἰς ἑαυτόν of the Emperor Marcus Aurelius Antoninus, in twelve books; he first of all ruled along with Lucius Aurelius Verus from 161 to 169 A.D., and then from 169 to 180 alone and he conducted a war with the Marcomanni. In his Meditations he always speaks to himself; these reflections are not, however, speculative in nature, being admonitions, such as that man should exercise himself in every virtue. We have no other original works by the older Stoics. For the Stoic Philosophy, too, the sources on which we formerly could count are cut off. The sources from which a knowledge of the philosophy of the Stoics is to be derived are, however, well known. There is Cicero, who was himself a Stoic, though in his representation there is great difficulty in discovering how, for instance, the principle of Stoic morality is to be distinguished from that which constitutes the principle of the morality of the Peripatetics. And, more particularly, we have Sextus Empiricus, whose treatment is mainly theoretic, and is thus interesting from a philosophic point of view. For Scepticism has had to do with Stoicism more especially. But also Seneca, Antoninus, Arrian, the manual of Epictetus, and Diogenes Laërtius must really be called into council. As regards the philosophy of the Stoics themselves, they definitely separated it into those three parts which we have already met with (Vol. I. p. 387, Vol. II. pp. 48, 49), and which will, generally speaking, be always found. There is Logic in the first place; secondly, Physics, or Natural Philosophy; and thirdly, Ethics, or the Philosophy of Mind, on the practical side especially. The content of their philosophy has, however, not much that is original or productive. 1. PHYSICS.
