2. The use of the term 'Sophist' in the dialogues of Plato also shows that the bad sense was not affixed by his genius, but already current. When Protagoras says, 'I confess that I am a Sophist,' he implies that the art which he professes has already a bad name; and the words of the young Hippocrates, when with a blush upon his face which is just seen by the light of dawn he admits that he is going to be made 'a Sophist,' would lose their point, unless the term had been discredited. There is nothing surprising in the Sophists having an evil name; that, whether deserved or not, was a natural consequence of their vocation. That they were foreigners, that they made fortunes, that they taught novelties, that they excited the minds of youth, are quite sufficient reasons to account for the opprobrium which attached to them. The genius of Plato could not have stamped the word anew, or have imparted the associations which occur in contemporary writers, such as Xenophon and Isocrates. Changes in the meaning of words can only be made with great difficulty, and not unless they are supported by a strong current of popular feeling. There is nothing improbable in supposing that Plato may have extended and envenomed the meaning, or that he may have done the Sophists the same kind of disservice with posterity which Pascal did to the Jesuits. But the bad sense of the word was not and could not have been invented by him, and is found in his earlier dialogues, e.g. the Protagoras, as well as in the later. 3. There is no ground for disbelieving that the principal Sophists, Gorgias, Protagoras, Prodicus, Hippias, were good and honourable men. The notion that they were corrupters of the Athenian youth has no real foundation, and partly arises out of the use of the term 'Sophist' in modern times. The truth is, that we know little about them; and the witness of Plato in their favour is probably not much more historical than his witness against them. Of that national decline of genius, unity, political force, which has been sometimes described as the corruption of youth, the Sophists were one among many signs;--in these respects Athens may have degenerated; but, as Mr. Grote remarks, there is no reason to suspect any greater moral corruption in the age of Demosthenes than in the age of Pericles. The Athenian youth were not corrupted in this sense, and therefore the Sophists could not have corrupted them. It is remarkable, and may be fairly set down to their credit, that Plato nowhere attributes to them that peculiar Greek sympathy with youth, which he ascribes to Parmenides, and which was evidently common in the Socratic circle. Plato delights to exhibit them in a ludicrous point of view, and to show them always rather at a disadvantage in the company of Socrates. But he has no quarrel with their characters, and does not deny that they are respectable men.
