121:1.5

Such are the lives of the several Cynics. But we will go on to append the doctrines which they held in common – if, that is, we decide that Cynicism is really a philosophy, and not, as some maintain, just a way of life. They are content then, like Ariston of Chios, to do away with the subjects of Logic and Physics and to devote their whole attention to Ethics. And what some assert of Socrates, Diocles records of Diogenes, representing him as saying: "We must inquire into Whate'er of good or ill within our halls is wrought." They also dispense with the ordinary subjects of instruction. At least Antisthenes used to say that those who had attained discretion had better not study literature, lest they should be perverted by alien influences.

To begin with, he became a pupil of Gorgias the rhetorician, and hence the rhetorical style that he introduces in his dialogues, and especially in his Truth and in his Exhortations. According to Hermippus he intended at the public gathering for the Isthmian games to discourse on the faults and merits of Athenians, Thebans and Lacedaemonians, but begged to be excused when he saw throngs arriving from those cities. Later on, however, he came into touch with Socrates, and derived so much benefit from him that he used to advise his own disciples to become fellow-pupils with him of Socrates. He lived in the Peiraeus, and every day would tramp the five miles to Athens in order to hear Socrates. From Socrates he learned his hardihood, emulating his disregard of feeling, and thus he inaugurated the Cynic way of life. He demonstrated that pain is a good thing by instancing the great Heracles and Cyrus, drawing the one example from the Greek world and the other from the barbarians.

Antisthenes gave the impulse to the indifference of Diogenes, the continence of Crates, and the hardihood of Zeno, himself laying the foundations of their state. Xenophon calls him the most agreeable of men in conversation and the most temperate in everything else. His writings are preserved in ten volumes. The first includes: A Treatise on Expression, or Styles of Speaking. Ajax, or The Speech of Ajax. Odysseus, or Concerning Odysseus. A Defence of Orestes, or Concerning Forensic Writers. Isography (similar writing), or Lysias and Isocrates. A Reply to the Speech of Isocrates entitled "Without Witnesses." Vol. 2 includes: Of the Nature of Animals. Of Procreation of Children, or Of Marriage: a discourse on love. Of the Sophists: a work on Physiognomy.
