1. According to the view of James Harris, in a long and valuable note communicated to Upton, the “master-argument” was so called from the supreme importance of the issues with which it dealt. On these issues different leaders of the Stoics took different sides, Diodorus holding both future and past things to be _necessary_, Cleanthes both _contingent_, and Chrysippus past things to be necessary and future contingent. Any two of the three propositions mentioned in the text exclude the third. For modern philosophy the distinction between the possible and the certain in the phenomenal world has, of course, no real existence; the possible being simply that of which we do not know whether it will come to pass or not. 2. Of course Epictetus here speaks ironically; all this is just what it _is_ the business of a thinker to do. 3. Epictetus, I suppose, means to complain that the current phrases of philosophy are dealt out in glib answer to great ethical questions, just as Homer might be quoted for an event in the life of Odysseus, by persons who in neither case think of gaining that vital conviction which only the strenuous exercise of one’s own reason can produce. A little later he represents Hellanicus, the historian, as quoted on the distinction between good and evil, who never treated that subject. If it is to be a mere question of _authority_, one _name_ is as good as another, since none is any use at all. “Indifferent,” be it observed, is _morally_ indifferent—that which has in _itself_ no bearing on our moral state. See Chap. II. 2. 4. The followers of Aristotle called themselves Peripatetics. CHAPTER II. 1. The word in the Greek is περιστάσεις, literally _circumstances_, but the word is evidently used in a bad sense, as equivalent to afflictions. Doom is likewise etymologically a neutral word, but one which has received an evil meaning. 2. Socrates’s faith in his genius or “Dæmon” was well known. In this passage from his _Apologia_ (which Epictetus gives from a bad text), it is doubtless the manner only that conveyed the idea of mockery. Neither Socrates nor any one else ever had better evidence of God’s existence than His voice in our conscience. CHAPTER IV. 1. Briefly, the three divisions seem to be Action, Character, and Judgment. The last is to be approached through training in logic, in the penetration of fallacies, etc., by which means a man is to arrive at such an inward and vital conviction of the truth that he can never for a moment be taken off his guard by the delusion of Appearance. 2. Passions, passionless, τὰ πάθη, ἀπαθής.—See Index of Philosophic Terms. CHAPTER V. 1. Euripides.—Musonius Rufus, the teacher of Epictetus, is reported to have said, “Take the chance of dying nobly when thou canst, lest after a little death indeed come to thee, but a noble death no more.”
