Oblige me by answering some questions; or rather, as circumstances will not admit of your answering, just nod or shake your head. If the flute of Timotheus, or that of Ismenias, which its owner sold in Corinth for a couple of thousand pounds, were to fall into the hands of a person who did not know how to play the instrument, would that make him a flute-player? would his acquisition leave him any wiser than it found him? You very properly shake your head. A man might possess the instrument of a Marsyas or an Olympus, and still he would not be able to play it if he had never learnt. Take another case: a man gets hold of Heracles’s bow and arrows: but he is no Philoctetes; he has neither that marksman’s strength nor his eye. What do you say? will he acquit himself creditably? Again you shake your head. The same will be the case with the ignorant pilot who is entrusted with a ship, or with the unpractised rider on horseback. Nothing is wanting to the beauty and efficiency of the vessel, and the horse may be a Median or a Thessalian or a Koppa [Footnote: The brand of the obsolete letter Koppa is supposed to have denoted the Corinthian breed.]: yet I take it that the incompetence of their respective owners will be made clear; am I right? And now let me ask your assent to one more proposition: if an illiterate person like yourself goes in for buying books, he is thereby laying himself open to ridicule. You hesitate? Yet surely nothing could be clearer: who could observe such a man at work, and abstain from the inevitable allusion to pearls and swine? There was a wealthy man in Asia, not many years ago, who was so unfortunate as to lose both his feet; I think he had been travelling through snow-drifts, and had got them frost-bitten. Well, of course, it was a very hard case; and in ordering a pair of wooden feet, by means of which he contrived to get along with the assistance of servants, he was no doubt only making the best of a bad job. But the absurd thing was, that he would always make a point of having the smartest and newest of shoes to set off his stumps—feet, I mean. Now are you any wiser than he, when for the adornment of that hobbling, wooden understanding of yours you go to the expense of such golden shoes as would tax the agility of a sound-limbed intellect?
