Then there are all the ordinary goods of life--beauty, wealth, strength, rank, and great connections in the State--you understand the sort of things--these also have a corrupting and distracting effect. I understand; but I should like to know more precisely what you mean about them. Grasp the truth as a whole, I said, and in the right way; you will then have no difficulty in apprehending the preceding remarks, and they will no longer appear strange to you. And how am I to do so? he asked. Why, I said, we know that all germs or seeds, whether vegetable or animal, when they fail to meet with proper nutriment or climate or soil, in proportion to their vigour, are all the more sensitive to the want of a suitable environment, for evil is a greater enemy to what is good than what is not. Very true. There is reason in supposing that the finest natures, when under alien conditions, receive more injury than the inferior, because the contrast is greater. Certainly. And may we not say, Adeimantus, that the most gifted minds, when they are ill-educated, become pre-eminently bad? Do not great crimes and the spirit of pure evil spring out of a fulness of nature ruined by education rather than from any inferiority, whereas weak natures are scarcely capable of any very great good or very great evil? There I think that you are right. And our philosopher follows the same analogy-he is like a plant which, having proper nurture, must necessarily grow and mature into all virtue, but, if sown and planted in an alien soil, becomes the most noxious of all weeds, unless he be preserved by some divine power. Do you really think, as people so often say, that our youth are corrupted by Sophists, or that private teachers of the art corrupt them in any degree worth speaking of? Are not the public who say these things the greatest of all Sophists? And do they not educate to perfection young and old, men and women alike, and fashion them after their own hearts? When is this accomplished? he said. When they meet together, and the world sits down at an assembly, or in a court of law, or a theatre, or a camp, or in any other popular resort, and there is a great uproar, and they praise some things which are being said or done, and blame other things, equally exaggerating both, shouting and clapping their hands, and the echo of the rocks and the place in which they are assembled redoubles the sound of the praise or blame--at such a time will not a young man's heart, as they say, leap within him? Will any private training enable him to stand firm against the overwhelming flood of popular opinion? or will he be carried away by the stream? Will he not have the notions of good and evil which the public in general have--he will do as they do, and as they are, such will he be? Yes, Socrates; necessity will compel him. And yet, I said, there is a still greater necessity, which has not been mentioned. What is that?
