Sec. II. O sirs, by asserting that virtue is not a thing to be taught, why are we making it unreal? For if teaching produces it, the deprivation of teaching prevents it. And yet, as Plato says, a discord and false note on the lyre makes not brother go to war with brother, nor sets friends at variance, nor makes states hostile to one another, so as to do and suffer at one another's hands the most dreadful things:[205] nor can anyone say that there was ever a dissension in any city as to the pronunciation of Telchines: nor in a private house any difference between man and wife as to woof and warp. And yet no one without learning would undertake to ply the loom, or write a book, or play on the lyre, though he would thereby do no great harm, but he fears making himself ridiculous, for as Heraclitus says, "It is better to hide one's ignorance," yet everyone thinks himself competent to manage a house and wife and the state and hold any magisterial office. On one occasion, when a boy was eating rather greedily, Diogenes gave the lad's tutor a blow with his fist, ascribing the fault not to the boy, who had not learnt how to eat properly, but to the tutor who had not taught him. And can one not properly handle a dish or a cup, unless one has learnt from a boy, as Aristophanes bids us, "not to giggle, nor eat too fast, nor cross our legs,"[206] and yet be perfectly fit to manage a family and city, and wife, and live well, and hold office, when one has not learnt how one should behave in the conduct of life? When Aristippus was asked by someone, "Are you everywhere then?" he smiled and said, "If I am everywhere, I lose my passage money."[207] Why should not you also say, "If men are not better for learning, the money paid to tutors is also lost?" For just as nurses mould with their hands the child's body, so tutors, receiving it immediately it is weaned, mould its soul, teaching it by habit the first vestiges of virtue. And the Lacedaemonian, who was asked, what good he did as a tutor, replied, "I make what is good pleasant to boys." Moreover tutors teach boys to walk in the streets with their heads down,[208] to touch salt fish with one finger only, other fish bread and meat with two, to scratch themselves in such a way, and in such a way to put on their cloak.[209]
