19. There are four states of the soul against which you must continually and especially be upon your guard; and which, when detected, should be effaced, by remarking thus of each. “This thought is unnecessary. This tends to social dissolution. You could not say this from your heart; and to speak otherwise than from the heart you must regard as the most absurd conduct.” And, fourthly, whatever causes self-reproach is an overpowering or subjection of the diviner part within you to the less honourable and mortal part, the body, and to its grosser tendencies.
20. The serial and igneous parts of which you are compounded, although they naturally tend upwards, nevertheless obey the general law of the Universe, and are retained here in composition. The earthy and humid parts of you, though they naturally tend downwards, are nevertheless supported and remain where they are, although not in their natural situation. Thus the elements, wheresoever placed by the superior power, obey the whole; waiting till the signal shall sound again for their dissolution. Is it not grievous that the intellectual part alone should be disobedient, and fret at its function? Yet is no violence done to it, nothing imposed contrary to its nature. Still it is impatient, and tends to opposition. For all its tendencies towards injustice, debauchery, wrath, sorrows, and fears are so many departures from Nature. And, when the soul frets at any particular event, it is deserting its appointed station. It is formed for holiness and piety toward God, no less than for justice. These last are branches of social goodness even more venerable than the practice of justice.
21. He whose aim in life is not always one and the same cannot himself be one and the same through his whole life. But singleness of aim is not sufficient, unless you consider also what that aim ought to be. For, as there is not agreement of opinion regarding all those things which are reckoned good by the majority, but only as regards some of them such as are of public utility; so your aim should be social and political. For he alone who directs all his personal aims to such an end can reach a uniform course of conduct, and thus be ever the same man.
22. Remember the country mouse and the town mouse; and how the latter feared and trembled.
23. Socrates called the maxims of the vulgar hobgoblins, bogies to frighten children.
24. The Spartans at their public shows set seats for strangers in the shade, but sat themselves where they found room.
25. Socrates made this excuse for not going to Perdiccas upon his invitation: “Lest I should come to the worst of all ends, by receiving favours which I could not return.”
26. In the writings of the Ephesians there is a precept, frequently to call to remembrance some of those who cultivated virtue of old.
27. The Pythagoreans recommended that we should look at the heavens in the morning, to put us in mind of beings that go on doing their proper work uniformly and continuously; and of their order, purity and naked simplicity; for there is no veil upon a star.
28. Think of Socrates clad in a skin, when Xanthippe had taken his cloak and gone out; and what he said to his friends, who were ashamed, and would have left him when they saw him dressed in such an extraordinary fashion.
