Benjamin Jowett

“ Socrates proceeds to undermine the last stronghold of the adversary, first obtaining from him the admission that all virtue is in the highest degree good:--
The courageous are the confident; and the confident are those who know their business or profession: those who have no such knowledge and are still confident are madmen. This is admitted. Then, says Socrates, courage is knowledge--an inference which Protagoras evades by drawing a futile distinction between the courageous and the confident in a fluent speech. ”

“ The real difficulties arise out of the extreme subtlety of the work, which, as Socrates says of the poem of Simonides, is a most perfect piece of art. There are dramatic contrasts and interests, threads of philosophy broken and resumed, satirical reflections on mankind, veils thrown over truths which are lightly suggested, and all woven together in a single design, and moving towards one end. ”

“ Here, as Aristotle remarks, Socrates and Plato outstep the truth--they make a part of virtue into the whole. Further, the nature of this knowledge, which is assumed to be a knowledge of pleasures and pains, appears to us too superficial and at variance with the spirit of Plato himself. Yet, in this, Plato is only following the historical Socrates as he is depicted to us in Xenophon's Memorabilia. Like Socrates, he finds on the surface of human life one common bond by which the virtues are united,--their tendency to produce happiness,--though such a principle is afterwards repudiated by him. ”

“ Some art of mensuration is required in order to show us pleasures and pains in their true proportion. This art of mensuration is a kind of knowledge, and knowledge is thus proved once more to be the governing principle of human life, and ignorance the origin of all evil: for no one prefers the less pleasure to the greater, or the greater pain to the less, except from ignorance. The argument is drawn out in an imaginary 'dialogue within a dialogue,' conducted by Socrates and Protagoras on the one part, and the rest of the world on the other. ”

“ Protagoras began by asserting, and Socrates by denying, the teachableness of virtue, and now the latter ends by affirming that virtue is knowledge, which is the most teachable of all things, while Protagoras has been striving to show that virtue is not knowledge, and this is almost equivalent to saying that virtue cannot be taught. ”

“ Hippias and Prodicus, as well as Protagoras, admit the soundness of the conclusion.
Socrates then applies this new conclusion to the case of courage--the only virtue which still holds out against the assaults of the Socratic dialectic. No one chooses the evil or refuses the good except through ignorance. This explains why cowards refuse to go to war:--because they form a wrong estimate of good, and honour, and pleasure. And why are the courageous willing to go to war?--because they form a right estimate of pleasures and pains, of things terrible and not terrible. ”

“ Before introducing Hippocrates to him, Socrates thinks proper to warn the youth against the dangers of 'influence,' of which the invidious nature is recognized by Protagoras himself. Hippocrates readily adopts the suggestion of Socrates that he shall learn of Protagoras only the accomplishments which befit an Athenian gentleman, and let alone his 'sophistry.' There is nothing however in the introduction which leads to the inference that Plato intended to blacken the character of the Sophists; he only makes a little merry at their expense. ”

“ For all men have the political virtues to a certain degree, and are obliged to say that they have them, whether they have them or not. A man would be thought a madman who professed an art which he did not know; but he would be equally thought a madman if he did not profess a virtue which he had not. ”

“ This, as Socrates admits, is a noble profession; but he is or rather would have been doubtful, whether such knowledge can be taught, if Protagoras had not assured him of the fact, for two reasons:
Because the Athenian people, who recognize in their assemblies the distinction between the skilled and the unskilled in the arts, do not distinguish between the trained politician and the untrained; Because the wisest and best Athenian citizens do not teach their sons political virtue. ”

“ To the doubt of Socrates the best answer is the fact, that the education of youth in virtue begins almost as soon as they can speak, and is continued by the state when they pass out of the parental control. Nor need we wonder that wise and good fathers sometimes have foolish and worthless sons. ”

“ This is an aspect of the truth which was lost almost as soon as it was found; and yet has to be recovered by every one for himself who would pass the limits of proverbial and popular philosophy. The moral and intellectual are always dividing, yet they must be reunited, and in the highest conception of them are inseparable. The thesis of Socrates is not merely a hasty assumption, but may be also deemed an anticipation of some 'metaphysic of the future,' in which the divided elements of human nature are reconciled. ”

“ Protagoras, whose temper begins to get a little ruffled at the process to which he has been subjected, is aware that he will soon be compelled by the dialectics of Socrates to admit that the temperate is the just. He therefore defends himself with his favourite weapon ”

“ The second question, whether the virtues are one or many, though at first sight distinct, is really a part of the same subject; for if the virtues are to be taught, they must be reducible to a common principle; and this common principle is found to be knowledge. ”

“ Protagoras selects as his thesis a poem of Simonides of Ceos, in which he professes to find a contradiction. First the poet says,
'Hard is it to become good,'
and then reproaches Pittacus for having said, 'Hard is it to be good.' How is this to be reconciled? Socrates, who is familiar with the poem, is embarrassed at first, and invokes the aid of Prodicus, the countryman of Simonides, but apparently only with the intention of flattering him into absurdities. First a distinction is drawn between (Greek) to be, and (Greek) to become: to become good is difficult; to be good is easy. ”

“ The argument is now resumed, not without some disdainful remarks of Socrates on the practice of introducing the poets, who ought not to be allowed, any more than flute-girls, to come into good society. Men's own thoughts should supply them with the materials for discussion. A few soothing flatteries are addressed to Protagoras by Callias and Socrates, and then the old question is repeated, 'Whether the virtues are one or many?' To which Protagoras is now disposed to reply, that four out of the five virtues are in some degree similar ”

“ He considers openness to be the best policy, and particularly mentions his own liberal mode of dealing with his pupils, as if in answer to the favourite accusation of the Sophists that they received pay. He is remarkable for the good temper which he exhibits throughout the discussion under the trying and often sophistical cross-examination of Socrates. ”

“ They seem to forget that Plato is a dramatic writer who throws his thoughts into both sides of the argument, and certainly does not aim at any unity which is inconsistent with freedom, and with a natural or even wild manner of treating his subject ”

“ In the introductory scene Plato raises the expectation that a 'great personage' is about to appear on the stage; perhaps with a further view of showing that he is destined to be overthrown by a greater still, who makes no pretensions. ”

“ And that the political virtues can be taught and acquired, in the opinion of the Athenians, is proved by the fact that they punish evil-doers, with a view to prevention, of course--mere retribution is for beasts, and not for men. ”
