19. There are four principal aberrations of the superior faculty against which thou shouldst be constantly on thy guard, and when thou hast detected them, thou shouldst wipe them out and say on each occasion thus: This thought is not necessary: this tends to destroy social union: this which thou art going to say comes not from the real thoughts; for thou shouldst consider it among the most absurd of things for a man not to speak from his real thoughts. But the fourth is when thou shalt reproach thyself for anything, for this is an evidence of the diviner part within thee being overpowered and yielding to the less honorable and to the perishable part, the body, and to its gross pleasures (IV. 24; II. 16).
20. Thy aerial part and all the fiery parts which are mingled in thee, though by nature they have an upward tendency, still in obedience to the disposition of the universe they are overpowered here in the compound mass [the body]. And also the whole of the earthy part in thee and the watery, though their tendency is downward, still are raised up and occupy a position which is not their natural one. In this manner then the elemental parts obey the universal; for when they have been fixed in any place, perforce they remain there until again the universal shall sound the signal for dissolution. Is it not then strange that thy intelligent part only should be disobedient and discontented with its own place? And yet no force is imposed on it, but only those things which are comformable to its nature: still it does not submit, but is carried in the opposite direction. For the movement towards injustice and intemperance and to anger and grief and fear is nothing else than the act of one who deviates from nature. And also when the ruling faculty is discontented with anything that happens, then too it deserts its post: for it is constituted for piety and reverence towards the gods no less than for justice. For these qualities also are comprehended under the generic term of contentment with the constitution of things, and indeed they are prior to acts of justice.
21. He who has not one and always the same object in life, cannot be one and the same all through his life. But what I have said is not enough, unless this also is added, what this object ought to be. For as there is not the same opinion about all the things which in some way or other are considered by the majority to be good, but only about some certain things, that is, things which concern the common interest, so also ought we to propose to ourselves an object which shall be of a common kind [social] and political. For he who directs all his own efforts to this object, will make all his acts alike, and thus will always be the same.
22. Think of the country mouse and of the town mouse, and of the alarm and trepidation of the town mouse.[[7]]
23. Socrates used to call the opinions of the many by the name of Lamiae,—bugbears to frighten children.
24. The Lacedaemonians at their public spectacles used to set seats in the shade for strangers, but themselves sat down anywhere.
25. Socrates excused himself to Perdiccas for not going to him, saying, It is because I would not perish by the worst of all ends; that is, I would not receive a favor and then be unable to return it.
26. In the writings of the [Ephesians] there was this precept, constantly to think of some one of the men of former times who practised virtue.
27. The Pythagoreans bid us in the morning look to the heavens that we may be reminded of those bodies which continually do the same things and in the same manner perform their work, and also be reminded of their purity and nudity. For there is no veil over a star.
28. Consider what a man Socrates was when he dressed himself in a skin, after Xanthippe had taken his cloak and gone out, and what Socrates said to his friends who were ashamed of him and drew back from him when they saw him dressed thus.
