But this opposition of good and evil is really the opposition of a greater or lesser amount of pleasure. Pleasures are evils because they end in pain, and pains are goods because they end in pleasures. Thus pleasure is seen to be the only good; and the only evil is the preference of the lesser pleasure to the greater.
But then comes in the illusion of distance. 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: 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: And why are the courageous willing to go to war? Courage then is knowledge, and cowardice is ignorance. And the five virtues, which were originally maintained to have five different natures, after having been easily reduced to two only, at last coalesce in one.
The assent of Protagoras to this last position is extracted with great difficulty. Socrates concludes by professing his disinterested love of the truth, and remarks on the singular manner in which he and his adversary had changed sides. 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.
He is not satisfied with the result, and would like to renew the enquiry with the help of Protagoras in a different order, asking 1 What virtue is, and 2 Whether virtue can be taught. The Protagoras is often supposed to be full of difficulties. These are partly imaginary and partly real. The imaginary ones are. But Plato, like all writers of fiction, aims only at the probable, and shows in many Dialogues e.
But there are no criteria which afford any real grounds for determining the date of composition; and the affinities of the Dialogues, when they are not indicated by Plato himself, must always to a great extent remain uncertain. 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; also that his mode of revealing the truth is by lights and shadows, and far-off and opposing points of view, and not by dogmatic statements or definite results.
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.
He is introduced on a stage which is worthy of him—at the house of the rich Callias, in which are congregated the noblest and wisest of the Athenians. 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. Nor is there anything in the sentiments of Protagoras which impairs this pleasing impression of the grave and weighty old man.
His real defect is that he is inferior to Socrates in dialectics. The opposition between him and Socrates is not the opposition of good and bad, true and false, but of the old art of rhetoric and the new science of interrogation and argument; also of the irony of Socrates and the self-assertion of the Sophists. There is quite as much truth on the side of Protagoras as of Socrates; but the truth of Protagoras is based on common sense and common maxims of morality, while that of Socrates is paradoxical or transcendental, and though full of meaning and insight, hardly intelligible to the rest of mankind.
Here as elsewhere is the usual contrast between the Sophists representing average public opinion and Socrates seeking for increased clearness and unity of ideas. But to a great extent Protagoras has the best of the argument and represents the better mind of man. There is no reason to suppose that in all this Plato is depicting an imaginary Protagoras; he seems to be showing us the teaching of the Sophists under the milder aspect under which he once regarded them.
Nor is there any reason to doubt that Socrates is equally an historical character, paradoxical, ironical, tiresome, but seeking for the unity of virtue and knowledge as for a precious treasure; willing to rest this even on a calculation of pleasure, and irresistible here, as everywhere in Plato, in his intellectual superiority. The aim of Socrates, and of the Dialogue, is to show the unity of virtue. In the determination of this question the identity of virtue and knowledge is found to be involved.
But if virtue and knowledge are one, then virtue can be taught; the end of the Dialogue returns to the beginning. Had Protagoras been allowed by Plato to make the Aristotelian distinction, and say that virtue is not knowledge, but is accompanied with knowledge; or to point out with Aristotle that the same quality may have more than one opposite; or with Plato himself in the Phaedo to deny that good is a mere exchange of a greater pleasure for a less—the unity of virtue and the identity of virtue and knowledge would have required to be proved by other arguments.
The victory of Socrates over Protagoras is in every way complete when their minds are fairly brought together. Protagoras falls before him after two or three blows. Socrates partially gains his object in the first part of the Dialogue, and completely in the second. Against the authority of the poets with whom Protagoras has ingeniously identified himself at the commencement of the Dialogue, Socrates sets up the proverbial philosophers and those masters of brevity the Lacedaemonians.
The poets, the Laconizers, and Protagoras are satirized at the same time. Not having the whole of this poem before us, it is impossible for us to answer certainly the question of Protagoras, how the two passages of Simonides are to be reconciled. We can only follow the indications given by Plato himself. But it seems likely that the reconcilement offered by Socrates is a caricature of the methods of interpretation which were practised by the Sophists—for the following reasons:.
The opposition of Greek and Greek seems also intended to express the rival doctrines of Socrates and Protagoras, and is a facetious commentary on their differences. At the same time Hippias is desirous of substituting a new interpretation of his own; as if the words might really be made to mean anything, and were only to be regarded as affording a field for the ingenuity of the interpreter.
The whole may also be considered as a satire on those who spin pompous theories out of nothing. All the interests and contrasts of character in a great dramatic work like the Protagoras are not easily exhausted. The impressiveness of the scene should not be lost upon us, or the gradual substitution of Socrates in the second part for Protagoras in the first.
The characters to whom we are introduced at the beginning of the Dialogue all play a part more or less conspicuous towards the end.
There is Alcibiades, who is compelled by the necessity of his nature to be a partisan, lending effectual aid to Socrates; there is Critias assuming the tone of impartiality; Callias, here as always inclining to the Sophists, but eager for any intellectual repast; Prodicus, who finds an opportunity for displaying his distinctions of language, which are valueless and pedantic, because they are not based on dialectic; Hippias, who has previously exhibited his superficial knowledge of natural philosophy, to which, as in both the Dialogues called by his name, he now adds the profession of an interpreter of the Poets.
The two latter personages have been already damaged by the mock heroic description of them in the introduction. It may be remarked that Protagoras is consistently presented to us throughout as the teacher of moral and political virtue; there is no allusion to the theories of sensation which are attributed to him in the Theaetetus and elsewhere, or to his denial of the existence of the gods in a well-known fragment ascribed to him; he is the religious rather than the irreligious teacher in this Dialogue. Also it may be observed that Socrates shows him as much respect as is consistent with his own ironical character; he admits that the dialectic which has overthrown Protagoras has carried himself round to a conclusion opposed to his first thesis.
The force of argument, therefore, and not Socrates or Protagoras, has won the day. These propositions to us have an appearance of paradox—they are really moments or aspects of the truth by the help of which we pass from the old conventional morality to a higher conception of virtue and knowledge. That virtue cannot be taught is a paradox of the same sort as the profession of Socrates that he knew nothing. Plato means to say that virtue is not brought to a man, but must be drawn out of him; and cannot be taught by rhetorical discourses or citations from the poets.
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. Here, as Aristotle remarks, Socrates and Plato outstep the truth—they make a part of virtue into the whole.
