Now the key to Plato's view of the Sophists, Gorgias, Protagoras, Hippias, Prodicus, with their less brilliant followers--chosen educators of the public--is that they do but fan and add fuel to the fire in which Greece, as they wander [106] like ardent missionaries about it, is flaming itself away. Teaching in their large, fashionable, expensive schools, so triumphantly well, the arts one needed most in so busy an age, they were really developing further and reinforcing the ruinous fluidity of the Greek, and especially of the Athenian people, by turning it very adroitly into a conscious method, a practical philosophy, an art of life itself, in which all those specific arts would be but subsidiary--an all-supplementing ars artium, a master-art, or, in depreciatory Platonic mood one might say, an artifice, or, cynically, a trick. The great sophist was indeed the Athenian public itself, Athens, as the willing victim of its own gifts, its own flamboyancy, well-nigh worn out now by the mutual friction of its own parts, given over completely to hazardous political experiment with the irresponsibility which is ever the great vice of democracy, ever ready to float away anywhither, to misunderstand, or forget, or discredit, its own past.-- Or do you too hold like the many (asks Socrates in the sixth book of The Republic) that a certain number are corrupted by sophists in their youth; and that certain sophists, irresponsible persons, corrupt them to any extent worth noting; and not rather that those who say these things are the greatest sophists; that they train to perfection, and turn out both old and young, men and women, just as they choose them to be?--When, pray? He asked.--When seated together in their thousands at the great assemblies, or in the law-courts, or the theatres, or the camp, or any other common gathering of the public, with much noise the majority praise this and blame [107] that in what is said and done, both alike in excess, shouting and clapping; and the very rocks too and the place in which they are, echoing around, send back redoubled that clamour of praise and blame. In such case, what heart as they say, what heart, think you, can the young man keep? or what private education he may have had hold out for him that it be not over-flooded by praise or blame like that, and depart away, borne down the stream, whithersoever that may carry it, and that he pronounce not the same thing as they fair or foul; and follow the same ways as they; and become like them?
