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 (ii. 380), 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. [Sidenote: _Good and pleasure._] Subordinate to the main purpose of the dialogue are some other questions, which may be briefly considered:—
