Marcus Agrippa, a great-souled man, the only person among those whom the civil wars raised to fame and power whose prosperity helped the state, used to say that he was greatly indebted to the proverb “Harmony makes small things grow; lack of harmony makes great things decay.”794 He held that he himself became the best of brothers and the best of friends by virtue of this saying. And if proverbs of such a kind, when welcomed intimately into the soul, can mould this very soul, why cannot the department of philosophy which consists of such proverbs possess equal influence? Virtue depends partly upon training and partly upon practice; you must learn first, and then strengthen your learning by action. If this be true, not only do the doctrines of wisdom help us but the precepts also, which check and banish our emotions by a sort of official decree.
It is said: “Philosophy is divided into knowledge and state of mind. For one who has learned and understood what he should do and avoid,795 is not a wise man until his mind is metamorphosed into the shape of that which he has learned. This third department—that of precept—is compounded from both the others, from dogmas of philosophy and state of mind. Hence it is superfluous as far as the perfecting of virtue is concerned; the other two parts are enough for the purpose.” On that basis, therefore, even consolation would be superfluous, since this also is a combination of the other two, as likewise are exhortation, persuasion, and even proof796 itself. For proof also originates from a well-ordered and firm mental attitude. But, although these things result from a sound state of mind, yet the sound state of mind also results from them; it is both creative of them and resultant from them. Furthermore, that which you mention is the mark of an already perfect man, of one who has attained the height of human happiness. But the approach to these qualities is slow, and in the meantime in practical matters, the path should be pointed out for the benefit of one who is still short of perfection, but is making progress. Wisdom by her own agency may perhaps show herself this path without the help of admonition; for she has brought the soul to a stage where it can be impelled only in the right direction. Weaker characters, however, need someone to precede them, to say: “Avoid this,” or “Do that.” Moreover, if one awaits the time when one can know of oneself what the best line of action is, one will sometimes go astray and by going astray will be hindered from arriving at the point where it is possible to be content with oneself. The soul should accordingly be guided at the very moment when it is becoming able to guide itself.797 Boys study according to direction. Their fingers are held and guided by others so that they may follow the outlines of the letters; next, they are ordered to imitate a copy and base thereon a style of penmanship. Similarly, the mind is helped if it is taught according to direction. Such facts as these prove that this department of philosophy is not superfluous.
The question next arises whether this part alone is sufficient to make men wise. The problem shall be treated at the proper time; but at present, omitting all arguments, is it not clear that we need someone whom we may call upon as our preceptor in opposition to the precepts of men in general? There is no word which reaches our ears without doing us harm; we are injured both by good wishes and by curses. The angry prayers of our enemies instil false fears in us; and the affection of our friends spoils us through their kindly wishes. For this affection sets us a-groping after goods that are far away, unsure, and wavering, when we really might open the store of happiness at home. We are not allowed, I maintain, to travel a straight road. Our parents and our slaves draw us into wrong. Nobody confines his mistakes to himself; people sprinkle folly among their neighbours, and receive it from them in turn. For this reason, in an individual, you find the vices of nations, because the nation has given them to the individual. Each man, in corrupting others, corrupts himself; he imbibes, and then imparts, badness:—the result is a vast mass of wickedness, because the worst in every separate person is concentrated in one mass.798
We should, therefore, have a guardian, as it were, to pluck us continually by the ear and dispel rumours and protest against popular enthusiasms. For you are mistaken if you suppose that our faults are inborn in us; they have come from without, have been heaped upon us. Hence, by receiving frequent admonitions, we can reject the opinions which din about our ears. Nature does not ally us with any vice; she produced us in health and freedom. She put before our eyes no object which might stir in us the itch of greed. She placed gold and silver beneath our feet, and bade those feet stamp down and crush everything that causes us to be stamped down and crushed. Nature elevated our gaze towards the sky and willed that we should look upward to behold her glorious and wonderful works. She gave us the rising and the setting sun, the whirling course of the on-rushing world which discloses the things of earth by day and the heavenly bodies by night, the movements of the stars, which are slow if you compare them with the universe, but most rapid if you reflect on the size of the orbits which they describe with unslackened
