Why, tell me what profit a wrestler gains from him who exercises him beforehand? The very greatest: he trains me in the practice of endurance, of controlling my temper, of gentle ways. You deny it. What, the man who lays hold of my neck, and disciplines loins and shoulders, does me good, . . . while he that trains me to keep my temper does me none? This is what it means, not knowing how to gain advantage from men! Is my neighbour bad? Bad to himself, but good to me: he brings my good temper, my gentleness into play. Is my father bad? Bad to himself, but good to me. This is the rod of Hermes; _touch what you will with it_, they say, _and it becomes gold_. Nay, but bring what you will and I will transmute it into Good. Bring sickness, bring death, bring poverty and reproach, bring trial for life—all these things through the rod of Hermes shall be turned to profit. CVII Till then these sound opinions have taken firm root in you, and you have gained a measure of strength for your security, I counsel you to be cautious in associating with the uninstructed. Else whatever impressions you receive upon the tablets of your mind in the School will day by day melt and disappear, like wax in the sun. Withdraw then somewhere far from the sun, while you have these waxen sentiments. CVIII We must approach this matter in a different way; it is great and mystical: it is no common thing; nor given to every man. Wisdom alone, it may be, will not suffice for the care of youth: a man needs also a certain measure of readiness—an aptitude for the office; aye, and certain bodily qualities; and above all, to be counselled of God Himself to undertake this post; even as He counselled Socrates to fill the post of one who confutes error, assigning to Diogenes the royal office of high reproof, and to Zeno that of positive instruction. Whereas _you_ would fain set up for a physician provided with nothing but drugs! Where and how they should be applied you neither know nor care. CIX If what charms you is nothing but abstract principles, sit down and turn them over quietly in your mind: but never dub yourself a Philosopher, nor suffer others to call you so. Say rather: He is in error; for my desires, my impulses are unaltered. I give in my adhesion to what I did before; nor has my mode of dealing with the things of sense undergone any change. CX
