[Sidenote: B] but if you make no scruple about offering reproof in public, you drive any moral disease or passion into becoming shameless. Plato insists that, if old men are to inculcate reverence in the young, they must themselves first show reverence towards the young. In the same way the friendly candour which most abashes is that which itself feels abashed. Let it be gently and considerately that you approach and handle the offender; then you undermine and destroy his vice, since regard is contagiously felt where regard is shown. Excellent, therefore, is the notion: _Putting his head close down, to the end that the rest should not hear it._ [Sidenote: C] Least propriety of all is there in exposing a husband in the hearing of the wife, a father before the eyes of his children, a lover in the presence of the beloved, or a teacher in that of his pupils. He becomes frantic; so sore and angry is he at being set right before persons in whose eyes he is all anxiety to shine. When Cleitus enraged Alexander, it was, I imagine, not so much the fault of the wine as that he appeared to be humbling him before a large company. Another case is that of Aristomenes, the tutor[54] of Ptolemy. Once, when an embassy was in the room, Ptolemy fell asleep and Aristomenes gave him a hit to wake him up. The flatterers seized the opportunity, and affected to be indignant on the king’s behalf. ‘If,’ said [Sidenote: D] they, ‘you did drop off, thanks to hard work and want of sleep, we ought to set you right privately, not lay hands on you before so many people.’ As the result, he sent Aristomenes a cup of poison and ordered him to drink it off. Aristophanes also tells us how Cleon tried to exasperate the Athenians against him by making it a charge that he _Abused the country before foreigners._ This, then, is another of the mistakes to be avoided, if your desire is not so much to make a self-advertising display as to make your candour produce helpful and healing results. In the next place, your plain-speaker ought to bear in mind [Sidenote: E] the principle which Thucydides makes the Corinthians so properly express, in saying that they ‘had a right to find fault’ with others. It was Lysander, I believe, who said to the man from Megara, when he was delivering himself at the Federal Council concerning the interests of Greece, ‘You need a country to back your talk.’ In any case, doubtless, you need character for plain-speaking, but in no case is this so true as when you are admonishing and lecturing other people. Plato used to say that it was by his life he admonished Speusippus, and the mere sight of Xenocrates at lecture, and a glance from him, [Sidenote: F] sufficed to convert Polemon to better ways. When we lack weight and strength of character the result of any attempt at plain-speaking on our part is to draw upon ourselves the words: _Why physic us, thyself one mass of sores?_
