The point which has to be considered, is the origin of this corruption in nature. *491* Every one will admit that the philosopher, in our description of him, is a rare being. But what numberless causes tend to destroy these rare beings! There is no good thing which may not be a cause of evil--health, wealth, strength, rank, and the virtues themselves, when placed under unfavourable circumstances. For as in the animal or vegetable world the strongest seeds most need the accompaniment of good air and soil, so the best of human characters turn out the worst when they fall upon an unsuitable soil; whereas weak natures hardly ever do any considerable good or harm; they are not the stuff out of which either great criminals or great heroes are made. *492* The philosopher follows the same analogy: he is either the best or the worst of all men. Some persons say that the Sophists are the corrupters of youth; but is not public opinion the real Sophist who is everywhere present--in those very persons, in the assembly, in the courts, in the camp, in the applauses and hisses of the theatre re-echoed by the surrounding hills? Will not a young man's heart leap amid these discordant sounds? and will any education save him from being carried away by the torrent? Nor is this all. For if he will not yield to opinion, there follows the gentle compulsion of exile or death. What principle of rival Sophists or anybody else can overcome in such an unequal contest? Characters there may be more than human, *493* who are exceptions--God may save a man, but not his own strength. Further, I would have you consider that the hireling Sophist only gives back to the world their own opinions; he is the keeper of the monster, who knows how to flatter or anger him, and observes the meaning of his inarticulate grunts. Good is what pleases him, evil what he dislikes; truth and beauty are determined only by the taste of the brute. Such is the Sophist's wisdom, and such is the condition of those who make public opinion the test of truth, whether in art or in morals. The curse is laid upon them of being and doing what it approves, and when they attempt first principles the failure is ludicrous. Think of all this and ask yourself whether the world is more likely to be a believer in the unity of the idea, or in the multiplicity of phenomena. And the world if not a believer {lxxxiii} in the idea cannot be a philosopher, *494* and must therefore be a persecutor of philosophers. There is another evil:--the world does not like to lose the gifted nature, and so they flatter the young [Alcibiades] into a magnificent opinion of his own capacity; the tall, proper youth begins to expand, and is dreaming of kingdoms and empires. If at this instant a friend whispers to him, 'Now the gods lighten thee; thou art a great fool' and must be educated--do you think that he will listen? Or suppose a better sort of man who is attracted towards philosophy, will they not make
