(3) Plato's theory of punishment is partly vindictive, partly corrective. In the Gorgias, as well as in the Phaedo and Republic, a few great criminals, chiefly tyrants, are reserved as examples. But most men have never had the opportunity of attaining this pre-eminence of evil. They are not incurable, and their punishment is intended for their improvement. They are to suffer because they have sinned; like sick men, they must go to the physician and be healed. On this representation of Plato's the criticism has been made, that the analogy of disease and injustice is partial only, and that suffering, instead of improving men, may have just the opposite effect.
Like the general analogy of the arts and the virtues, the analogy of disease and injustice, or of medicine and justice, is certainly imperfect. But ideas must be given through something; the nature of the mind which is unseen can only be represented under figures derived from visible objects. If these figures are suggestive of some new aspect under which the mind may be considered, we cannot find fault with them for not exactly coinciding with the ideas represented. They partake of the imperfect nature of language, and must not be construed in too strict a manner. That Plato sometimes reasons from them as if they were not figures but realities, is due to the defective logical analysis of his age.
Nor does he distinguish between the suffering which improves and the suffering which only punishes and deters. He applies to the sphere of ethics a conception of punishment which is really derived from criminal law. He does not see that such punishment is only negative, and supplies no principle of moral growth or development. He is not far off the higher notion of an education of man to be begun in this world, and to be continued in other stages of existence, which is further developed in the Republic. And Christian thinkers, who have ventured out of the beaten track in their meditations on the 'last things,' have found a ray of light in his writings. But he has not explained how or in what way punishment is to contribute to the improvement of mankind. He has not followed out the principle which he affirms in the Republic, that 'God is the author of evil only with a view to good,' and that 'they were the better for being punished.' Still his doctrine of a future state of rewards and punishments may be compared favourably with that perversion of Christian doctrine which makes the everlasting punishment of human beings depend on a brief moment of time, or even on the accident of an accident. And he has escaped the difficulty which has often beset divines, respecting the future destiny of the meaner sort of men (Thersites and the like), who are neither very good nor very bad, by not counting them worthy of eternal damnation.
We do Plato violence in pressing his figures of speech or chains of argument; and not less so in asking questions which were beyond the horizon of his vision, or did not come within the scope of his design. The main purpose of the Gorgias is not to answer questions about a future world, but to place in antagonism the true and false life, and to contrast the judgments and opinions of men with judgment according to the truth. Plato may be accused of representing a superhuman or transcendental virtue in the description of the just man in the Gorgias, or in the companion portrait of the philosopher in the Theaetetus; and at the same time may be thought to be condemning a state of the world which always has existed and always will exist among men. But such ideals act powerfully on the imagination of mankind. And such condemnations are not mere paradoxes of philosophers, but the natural rebellion of the higher sense of right in man against the ordinary conditions of human life. The greatest statesmen have fallen very far short of the political ideal, and are therefore justly involved in the general condemnation.
Subordinate to the main purpose of the dialogue are some other questions, which may be briefly considered:—
a. The antithesis of good and pleasure, which as in other dialogues is supposed to consist in the permanent nature of the one compared with the transient and relative nature of the other. Good and pleasure, knowledge and sense, truth and opinion, essence and generation, virtue and pleasure, the real and the apparent, the infinite and finite, harmony or beauty and discord, dialectic and rhetoric or poetry, are so many pairs of opposites, which in Plato easily pass into one another, and are seldom kept perfectly distinct. And we must not forget that Plato's conception of pleasure is the Heracleitean flux transferred to the sphere of human conduct. There is some degree of unfairness in opposing the principle of good, which is objective, to the principle of pleasure, which is subjective. For the assertion of the permanence of good is only based on the assumption of its objective character. Had Plato fixed his mind, not on the ideal nature of good, but on the subjective consciousness of happiness, that would have been found to be as transient and precarious as pleasure.
b. The arts or sciences, when pursued without any view to truth, or the improvement of human life, are called flatteries. They are all alike dependent upon the opinion of mankind, from which they are derived. To Plato the whole world appears to be sunk in error, based on self-interest. To this is opposed the one wise man hardly professing to have found truth, yet strong in the conviction that a virtuous life is the only good, whether regarded with reference to this world or to another. Statesmen, Sophists, rhetoricians, poets, are alike brought up for judgment. They are the parodies of wise men, and their arts are the parodies of true arts and sciences. All that they call science is merely the result of that study of the tempers of the Great Beast, which he describes in the Republic.
c. Various other points of contact naturally suggest themselves between the Gorgias and other dialogues, especially the Republic, the Philebus, and the Protagoras. There are closer resemblances both of spirit and language in the Republic than in any other dialogue, the verbal similarity tending to show that they were written at the same period of Plato's life. For the Republic supplies that education and training of which the Gorgias suggests the necessity. The theory of the many weak combining against the few strong in the formation of society (which is indeed a partial truth), is similar in both of them, and is expressed in nearly the same language. The sufferings and fate of the just man, the powerlessness of evil, and the reversal of the situation in another life, are also points of similarity. The poets, like the rhetoricians, are condemned because they aim at pleasure only, as in the Republic they are expelled the State, because they are imitators, and minister to the weaker side of human nature. That poetry is akin to rhetoric may be compared with the analogous notion, which occurs in the Protagoras, that the ancient poets were the Sophists of their day. In some other respects the Protagoras rather offers a contrast than a parallel. The character of Protagoras may be compared with that of Gorgias, but the conception of happiness is different in the two dialogues; being described in the former, according to the old Socratic notion, as deferred or accumulated pleasure, while in the Gorgias, and in the Phaedo, pleasure and good are distinctly opposed.
This opposition is carried out from a speculative point of view in the Philebus. There neither pleasure nor wisdom are allowed to be the chief good, but pleasure and good are not so completely opposed as in the Gorgias. For innocent pleasures, and such as have no antecedent pains, are allowed to rank in the class of goods. The allusion to Gorgias' definition of rhetoric (Philebus; compare Gorg.), as the art of persuasion, of all arts the best, for to it all things submit, not by compulsion, but of their own free will—marks a close and perhaps designed connection between the two dialogues. In both the ideas of measure, order, harmony, are the connecting links between the beautiful and the good.
In general spirit and character, that is, in irony and antagonism to public opinion, the Gorgias most nearly resembles the Apology, Crito, and portions of the Republic, and like the Philebus, though from another point of view, may be thought to stand in the same relation to Plato's theory of morals which the Theaetetus bears to his theory of knowledge.
d. A few minor points still remain to be summed up: (1) The extravagant irony in the reason which is assigned for the pilot's modest charge; and in the proposed use of rhetoric as an instrument of self-condemnation; and in the mighty power of geometrical equality in both worlds. (2) The reference
