Nor again, (2) must we forget that Plato, though he agrees generally with the view implied in the argument of the two brothers, is not expressing his own final conclusion, but rather seeking to dramatize one of the aspects of ethical truth. He is developing his idea gradually in a series of positions or situations. He is exhibiting Socrates for the first time undergoing the Socratic interrogation. Lastly, (3) the word “happiness” involves some degree of confusion because associated in the language of modern philosophy with conscious pleasure or satisfaction, which was not equally present to his mind.
Glaucon has been drawing a picture of the misery of the just and the happiness of the unjust, to which the misery of the tyrant in Book IX is the answer and parallel. And still the unjust must appear just; that is “the homage which vice pays to virtue.” But now Adeimantus, taking up the hint which had been already given by Glaucon (II 358 C), proceeds to show that in the opinion of mankind justice is regarded only for the sake of rewards and reputation, and points out the advantage which is given to such arguments as those of Thrasymachus and Glaucon by the conventional morality of mankind. He seems to feel the difficulty of “justifying the ways of God to man.” Both the brothers touch upon the question, whether the morality of actions is determined by their consequences (compare IV 420 following); and both of them go beyond the position of Socrates, that justice belongs to the class of goods not desirable for themselves only, but desirable for themselves and for their results, to which he recalls them. In their attempt to view justice as an internal principle, and in their condemnation of the poets, they anticipate him. The common life of Greece is not enough for them; they must penetrate deeper into the nature of things.
It has been objected that justice is honesty in the sense of Glaucon and Adeimantus, but is taken by Socrates to mean all virtue. May we not more truly say that the old-fashioned notion of justice is enlarged by Socrates, and becomes equivalent to universal order or well-being, first in the State, and secondly in the individual? He has found a new answer to his old question (“Protagoras” 329), “whether the virtues are one or many,” viz. that one is the ordering principle of the three others. In seeking to establish the purely internal nature of justice, he is met by the fact that man is a social being, and he tries to harmonise the two opposite theses as well as he can. There is no more inconsistency in this than was inevitable in his age and country; there is no use in turning upon him the cross lights of modern philosophy, which, from some other point of view, would appear equally inconsistent. Plato does not give the final solution of philosophical questions for us; nor can he be judged of by our standard.
The remainder of the Republic is developed out of the question of the sons of Ariston. Three points are deserving of remark in what immediately follows:—First, that the answer of Socrates is altogether indirect. He does not say that happiness consists in the contemplation of the idea of justice, and still less will he be tempted to affirm the Stoical paradox that the just man can be happy on the rack. But first he dwells on the difficulty of the problem and insists on restoring man to his natural condition, before he will answer the question at all. He too will frame an ideal, but his ideal comprehends not only abstract justice, but the whole relations of man. Under the fanciful illustration of the large letters he implies that he will only look for justice in society, and that from the State he will proceed to the individual. His answer in substance amounts to this—that under favourable conditions, i.e. in the perfect State, justice and happiness will coincide, and that when justice has been once found, happiness may be left to take care of itself. That he falls into some degree of inconsistency, when in the tenth book (612 A) he claims to have got rid of the rewards and honours of justice, may be admitted; for he has left those which exist in the perfect State. And the philosopher “who retires under the shelter of a wall” (VI 496) can hardly have been esteemed happy by him, at least not in this world. Still he maintains the true attitude of moral action. Let a man do his duty first, without asking whether he will be happy or not, and happiness will be the inseparable accident which attends him. “Seek ye first the kingdom of God and his righteousness, and all these things shall be added unto you.”
Secondly, it may be remarked that Plato preserves the genuine character of Greek thought in beginning with the State and in going on to the individual. First ethics, then politics—this is the order of ideas
