The 'Chalcedonian giant,' Thrasymachus, of whom we have already heard in the Phaedrus, is the personification of the Sophists, according to Plato's conception of them, in some of their worst characteristics. He is vain and blustering, refusing to discourse unless he is paid, fond of making an oration, and hoping thereby to escape the inevitable Socrates; but a mere child in argument, and unable to foresee that the next 'move' (to use a Platonic expression) will 'shut him up.' He has reached the stage of framing general notions, and in this respect is in advance of Cephalus and Polemarchus. But he is incapable of defending them in a discussion, and vainly tries to cover his confusion with banter and insolence. Whether such doctrines as are attributed to him by Plato were really held either by him or by any other Sophist is uncertain; in the infancy of philosophy serious errors about morality might easily grow up – they are certainly put into the mouths of speakers in Thucydides; but we are concerned at present with Plato's description of him, and not with the historical reality. The inequality of the contest adds greatly to the humour of the scene. The pompous and empty Sophist is utterly helpless in the hands of the great master of dialectic, who knows how to touch all the springs of vanity and weakness in him. He is greatly irritated by the irony of Socrates, but his noisy and imbecile rage only lays him more and more open to the thrusts of his assailant. His determination to cram down their throats, or put 'bodily into their souls' his own words, elicits a cry of horror from Socrates. The state of his temper is quite as worthy of remark as the process of the argument. Nothing is more amusing than his complete submission when he has been once thoroughly beaten. At first he seems to continue the discussion with reluctance, but soon with apparent good-will, and he even testifies his interest at a later stage by one or two occasional remarks. When attacked by Glaucon he is humorously protected by Socrates 'as one who has never been his enemy and is now his friend.' From Cicero and Quintilian and from Aristotle's Rhetoric we learn that the Sophist whom Plato has made so ridiculous was a man of note whose writings were preserved in later ages. The play on his name which was made by his contemporary Herodicus (Aris. Rhet.), 'thou wast ever bold in battle,' seems to show that the description of him is not devoid of verisimilitude.
When Thrasymachus has been silenced, the two principal respondents, Glaucon and Adeimantus, appear on the scene: here, as in Greek tragedy (cp. Introd. to Phaedo), three actors are introduced. At first sight the two sons of Ariston may seem to wear a family likeness, like the two friends Simmias and Cebes in the Phaedo. But on a nearer examination of them the similarity vanishes, and they are seen to be distinct characters. Glaucon is the impetuous youth who can 'just never have enough of fechting' (cp. the character of him in Xen. Mem. iii. 6); the man of pleasure who is acquainted with the mysteries of love; the 'juvenis qui gaudet canibus,' and who improves the breed of animals; the lover of art and music who has all the experiences of youthful life. He is full of quickness and penetration, piercing easily below the clumsy platitudes of Thrasymachus to the real difficulty; he turns out to the light the seamy side of human life, and yet does not lose faith in the just and true. It is Glaucon who seizes what may be termed the ludicrous relation of the philosopher to the world, to whom a state of simplicity is 'a city of pigs,' who is always prepared with a jest when the argument offers him an opportunity, and who is ever ready to second the humour of Socrates and to appreciate the ridiculous, whether in the connoisseurs of music, or in the lovers of theatricals, or in the fantastic behaviour of the citizens of democracy. His weaknesses are several times alluded to by Socrates, who, however, will not allow him to be attacked by his brother Adeimantus. He is a soldier, and, like Adeimantus, has been distinguished at the battle of Megara (anno 456?)…The character of Adeimantus is deeper and graver, and the profounder objections are commonly put into his mouth. Glaucon is more demonstrative, and generally opens the game. Adeimantus pursues the argument further. Glaucon has more of the liveliness and quick sympathy of youth; Adeimantus has the maturer judgment of a grown-up man of the world. In the second book, when Glaucon insists that justice and injustice shall be considered without regard to their consequences, Adeimantus remarks that they are regarded by mankind in general only for the sake of their consequences; and in a similar vein of reflection he urges at the beginning of the fourth book that Socrates fails in making his citizens happy, and is answered that happiness is not the first but the second thing, not the direct aim but the indirect consequence of the good government of a State. In the discussion about religion and mythology, Adeimantus is the respondent, but Glaucon breaks in with a slight jest, and carries on the conversation in a lighter tone about music and gymnastic to the end of the book. It is Adeimantus again who volunteers the criticism of common sense on the Socratic method of argument, and who refuses to let Socrates pass lightly over the question of women and children. It is Adeimantus who is the respondent in the more argumentative, as Glaucon in the lighter and more imaginative portions of the Dialogue. For example, throughout the greater part of the sixth book, the causes of the corruption of philosophy and the conception of the idea of good are discussed with Adeimantus. Glaucon resumes his place of principal respondent; but he has a difficulty in apprehending the higher education of Socrates, and makes some false hits in the course of the discussion. Once more Adeimantus returns with the allusion to his brother Glaucon whom he compares to the contentious State; in the next book he is again superseded, and Glaucon continues to the end.
Thus in a succession of characters Plato represents the successive stages of morality, beginning with the Athenian gentleman of the olden time, who is followed by the practical man of that day regulating his life by proverbs and saws; to him succeeds the wild generalization of the Sophists, and lastly come the young disciples of the great teacher, who know the sophistical arguments but will not be convinced by them, and desire to go deeper into the nature of things. These too, like Cephalus, Polemarchus, Thrasymachus, are clearly distinguished from one another. Neither in the Republic, nor in any other Dialogue of Plato, is a single character repeated.
The delineation of Socrates in the Republic is not wholly consistent. In the first book we have more of the real Socrates, such as he is depicted in the Memorabilia of Xenophon, in the earliest Dialogues of Plato, and in the Apology. He is ironical, provoking, questioning, the old enemy of the Sophists, ready to put on the mask of Silenus as well as to argue seriously. But in the sixth book his enmity towards the Sophists abates; he acknowledges that they are the representatives rather than the corrupters of the world. He also becomes more dogmatic and constructive, passing beyond the range either of the political or the speculative ideas of the real Socrates. In one passage Plato himself seems to intimate that the time had now come for Socrates, who had passed his whole life in philosophy, to give his own opinion and not to be always repeating the notions of other men. There is no evidence that either the idea of good or the conception of a perfect state were comprehended in the Socratic teaching, though he certainly dwelt on the nature of the universal and of final causes (cp. Xen. Mem.; Phaedo); and a deep thinker like him, in his thirty or forty years of public teaching, could hardly have failed to touch on the nature of family relations, for which there is also some positive evidence in the Memorabilia (Mem.) The Socratic method is nominally retained; and every inference is either put into the mouth of the respondent or represented as the common discovery of him and Socrates. But any one can see that this is a mere form, of which the affectation grows wearisome as the work advances. The method of enquiry has passed into a method of teaching in which by the help of interlocutors the same thesis is looked at from various points of view. The nature of the process is truly characterized by Glaucon, when he describes himself as a companion who is not good for much in an investigation, but can see what he is shown, and may, perhaps, give the answer to a question more fluently than another.
Neither can we be absolutely certain that Socrates himself taught the immortality of the soul, which is unknown to his disciple Glaucon in the Republic (cp. Apol.); nor is there any reason to suppose that he used myths or revelations of another world as a vehicle of instruction, or that he would have banished poetry or have denounced the Greek mythology. His favorite oath is retained, and a slight mention is made of the daemonium, or internal sign, which is alluded to by Socrates as a phenomenon peculiar to himself. A real element of Socratic teaching, which is more prominent in the Republic than in any of the other Dialogues of Plato, is the use of example and illustration (Greek): 'Let us apply the test of common instances.' 'You,' says Adeimantus, ironically, in the sixth book, 'are so unaccustomed to speak in images.' And this use of examples or images, though truly Socratic in origin, is enlarged by the genius of Plato into the form of an allegory or parable, which embodies in the concrete what has been already described, or is about to be described, in the abstract. Thus the figure of the cave in Book VII is a recapitulation of the divisions of knowledge in Book VI. The composite animal in Book IX is an allegory of the parts of the soul. The noble captain and the ship and the true pilot in Book VI are a figure of the relation of the people to the philosophers in the State which has been described. Other figures, such as the dog, or the marriage of the portionless maiden, or the drones and wasps in the eighth and ninth books, also form links of connexion in long passages, or are used to recall previous discussions.
Plato is most true to the character of his master when he describes him as 'not of this world.' And with this representation of him the ideal state and the other paradoxes of the Republic are quite in accordance, though they cannot be shown to have been speculations of Socrates. To him, as to other great teachers both philosophical and religious, when they looked upward, the world seemed to be the embodiment of error and evil. The common sense of mankind has revolted against this view, or has only partially admitted it. And even in Socrates himself the sterner judgement of the multitude at times passes into a sort of ironical pity or love. Men in general are incapable of philosophy, and are therefore at enmity with the philosopher; but their misunderstanding of him is unavoidable: for they have never seen him as he truly is in his own image; they are only acquainted with artificial systems possessing no native force of truth – words which admit of many applications. Their leaders have nothing to measure with, and are therefore ignorant of their own stature. But they are to be pitied or laughed at, not to be quarrelled with; they mean well with their nostrums, if they could only learn that they are cutting off a Hydra's head. This moderation towards those who are in error is one of the most characteristic features of Socrates in the Republic. In all the different representations of Socrates, whether of Xenophon or Plato, and amid the differences of the earlier or later Dialogues, he always retains the character of the unwearied and disinterested seeker after truth, without which he would have ceased to be Socrates.
Leaving the characters we may now analyse the contents of the Republic, and then proceed to consider (1) The general aspects of this Hellenic ideal of the State, (2) The modern lights in which the thoughts of Plato may be read.
BOOK I. The Republic opens with a truly Greek scene – a festival in honour of the goddess Bendis which is held in the Piraeus; to this is added the promise of an equestrian torch-race in the evening. The whole work is supposed to be recited by Socrates on the day after the festival to a small party, consisting of Critias, Timaeus, Hermocrates, and another; this we learn from the first words of the Timaeus.
When the rhetorical advantage of reciting the Dialogue has been gained, the attention is not distracted by any reference to the audience; nor is the reader further reminded of the extraordinary length of the narrative. Of the numerous company, three only take any serious part in the discussion; nor are we informed whether in the evening they went to the torch-race, or talked, as in the Symposium, through the night. The manner in which the conversation has arisen is described as follows: – Socrates and his companion Glaucon are about to leave the festival when they are detained by a message from Polemarchus, who speedily appears accompanied by Adeimantus, the brother of Glaucon, and with playful violence compels them to remain, promising them not only the torch-race, but the pleasure of conversation with the young, which to Socrates is a far greater attraction. They return to the house of Cephalus, Polemarchus' father, now in extreme old age, who is found sitting upon a cushioned seat crowned for a sacrifice. 'You should come to me oftener, Socrates, for I am too old to go to you; and at my time of life, having lost other pleasures, I care the more for conversation.' Socrates asks him what he thinks of age, to which the old man replies, that the sorrows and discontents of age are to be attributed to the tempers of men, and that age is a time of peace in which the tyranny of the passions is no longer felt. Yes, replies Socrates, but the world will say, Cephalus, that you are happy in old age because you are rich. 'And there is something in what they say, Socrates, but not so much as they imagine – as Themistocles replied to the Seriphian, "Neither you, if you had been an Athenian, nor I, if I had been a Seriphian, would ever have been famous," I might in like manner reply to you, Neither a good poor man can be happy in age, nor yet a bad rich man.' Socrates remarks that Cephalus appears not to care about riches, a quality which he ascribes to his having inherited, not acquired them, and would like to know what he considers to be the chief advantage of them. Cephalus answers that when you are old the belief in the world below grows upon you, and then to have done justice and never to have been compelled to do injustice through poverty, and never to have deceived anyone, are felt to be unspeakable blessings. Socrates, who is evidently preparing for an argument, next asks, What is the meaning of the word justice? To tell the truth and pay your debts? No more than this? Or must we admit exceptions? Ought I, for example, to put back into the hands of my friend, who has gone mad, the sword which I borrowed of him when he was in his right mind? 'There must be exceptions.' 'And yet,' says Polemarchus, 'the definition which has been given has the authority of Simonides.' Here Cephalus retires to look after the sacrifices, and bequeaths, as Socrates facetiously remarks, the possession of the argument to his heir, Polemarchus…
The description of old age is finished, and Plato, as his manner is, has touched the key-note of the whole work in asking for the definition of justice, first suggesting the question which Glaucon afterwards pursues respecting external goods, and preparing for the concluding mythus of the world below in the slight allusion of Cephalus. The portrait of the just man is a natural frontispiece or introduction to the long discourse which follows, and may perhaps imply that in all our perplexity about the nature of justice, there is no difficulty in discerning 'who is a just man.' The first explanation has been supported by a saying of Simonides; and now Socrates has a mind to show that the resolution of justice into two unconnected precepts, which have no common principle, fails to satisfy the demands of dialectic.
…He proceeds: What did Simonides mean by this saying of his? Did he mean that I was to give back arms to a madman? 'No, not in that case, not if the parties are friends, and evil would result. He meant that you were to do what was proper, good to friends and harm to enemies.' Every act does something to somebody; and following this analogy, Socrates asks, What is this due and proper thing which justice does, and to whom? He is answered that justice does good to friends and harm to enemies. But in what way good or harm? 'In making alliances with the one, and going to war with the other.' Then in time of peace what is the good of justice? The answer is that justice is of use in contracts, and contracts are money partnerships. Yes; but how in such partnerships is the just man of more use than any other man? 'When you want to have money safely kept and not used.' Then justice will be useful when money is useless. And there is another difficulty: justice, like the art of war or any other art, must be of opposites, good at attack as well as at defence, at stealing as well as at guarding. But then justice is a thief, though a hero notwithstanding, like Autolycus, the Homeric hero, who was 'excellent above all men in theft and perjury' – to such a pass have you and Homer and Simonides brought us; though I do not forget that the thieving must be for the good of friends and the harm of enemies. And still there arises another question: Are friends to be interpreted as real or seeming; enemies as real or seeming? And are our friends to be only the good, and our enemies to be the evil? The answer is, that we must do good to our seeming and real good friends, and evil to our seeming and real evil enemies – good to the good, evil to the evil. But ought we to render evil for evil at all, when to do so will only make men more evil? Can justice produce injustice any more than the art of horsemanship can make bad horsemen, or heat produce cold? The final conclusion is, that no sage or poet ever said that the just return evil for evil; this was a maxim of some rich and mighty man, Periander, Perdiccas, or Ismenias the Theban (about B.C. 398-381)…
Thus the first stage of aphoristic or unconscious morality is shown to be inadequate to the wants of the age; the authority of the poets is set aside, and through the winding mazes of dialectic we make an approach to the Christian precept of forgiveness of injuries. Similar words are applied by the Persian mystic poet to the Divine being when the questioning spirit is stirred within him: – 'If because I do evil, Thou punishest me by evil, what is the difference between Thee and me?' In this both Plato and Kheyam rise above the level of many Christian (?) theologians. The first definition of justice easily passes into the second; for the simple words 'to speak the truth and pay your debts' is substituted the more abstract 'to do good to your friends and harm to your enemies.' Either of these explanations gives a sufficient rule of life for plain men, but they both fall short of the precision of philosophy. We may note in passing the antiquity of casuistry, which not only arises out of the conflict of established principles in particular cases, but also out of the effort to attain them, and is prior as well as posterior to our fundamental notions of morality. The 'interrogation' of moral ideas; the appeal to the authority of Homer; the conclusion that the maxim, 'Do good to your friends and harm to your enemies,' being erroneous, could not have been the word of any great man, are all of them very characteristic of the Platonic Socrates.
…Here Thrasymachus, who has made several attempts to interrupt, but has hitherto been kept in order by the company, takes advantage of a pause and rushes into the arena, beginning, like a savage animal, with a roar. 'Socrates,' he says, 'what folly is this? – Why do you agree to be vanquished by one another in a pretended argument?' He then prohibits all the ordinary definitions of justice; to which Socrates replies that he cannot tell how many twelve is, if he is forbidden to say 2 x 6, or 3 x 4, or 6 x 2, or 4 x 3. At first Thrasymachus is reluctant to argue; but at length, with a promise of payment on the part of the company and of praise from Socrates, he is induced to open the game. 'Listen,' he says, 'my answer is that might is right, justice the interest of the stronger: now praise me.' Let me understand you first. Do you mean that because Polydamas the wrestler, who is stronger than we are, finds the eating of beef for his interest, the eating of beef is also for our interest, who are not so strong? Thrasymachus is indignant at the illustration, and in pompous words, apparently intended to restore dignity to the argument, he explains his meaning to be that the rulers make laws for their own interests. But suppose, says Socrates, that the ruler or stronger makes a mistake – then the interest of the stronger is not his interest. Thrasymachus is saved from this speedy downfall by his disciple Cleitophon, who introduces the word 'thinks;' – not the actual interest of the ruler, but what he thinks or what seems to be his interest, is justice. The contradiction is escaped by the unmeaning evasion: for though his real and apparent interests may differ, what the ruler thinks to be his interest will always remain what he thinks to be his interest.
Of course this was not the original assertion, nor is the new interpretation accepted by Thrasymachus himself. But Socrates is not disposed to quarrel about words, if, as he significantly insinuates, his adversary has changed his mind. In what follows Thrasymachus does in fact withdraw his admission that the ruler may make a mistake, for he affirms that the ruler as a ruler is infallible. Socrates is quite ready to accept the new position, which he equally turns against Thrasymachus by the help of the analogy of the arts. Every art or science has an interest, but this interest is to be distinguished from the accidental interest of the artist, and is only concerned with the good of the things or persons which come under the art. And justice has an interest which is the interest not of the ruler or judge, but of those who come under his sway.
Thrasymachus is on the brink of the inevitable conclusion, when he makes a bold diversion. 'Tell me, Socrates,' he says, 'have you a nurse?' What a question! Why do you ask? 'Because, if you have, she neglects you and lets you go about drivelling, and has not even taught you to know the shepherd from the sheep. For you fancy that shepherds and rulers never think of their own interest, but only of their sheep or subjects, whereas the truth is that they fatten them for their use, sheep and subjects alike. And experience proves that in every relation of life the just man is the loser and the unjust the gainer, especially where injustice is on the grand scale, which is quite another thing from the petty rogueries of swindlers and burglars and robbers of temples. The language of men proves this – our 'gracious' and 'blessed' tyrant and the like – all which tends to show (1) that justice is the interest of the stronger; and (2) that injustice is more profitable and also stronger than justice.'
Thrasymachus, who is better at a speech than at a close argument, having deluged the company with words, has a mind to escape. But the others will not let him go, and Socrates adds a humble but earnest request that he will not desert them at such a crisis of their fate. 'And what can I do more for you?' he says; 'would you have me put the words bodily into your souls?' God forbid! replies Socrates; but we want you to be consistent in the use of terms, and not to employ 'physician' in an exact sense, and then again 'shepherd' or 'ruler' in an inexact, – if the words are strictly taken, the ruler and the shepherd look only to the good of their people or flocks and not to their own: whereas you insist that rulers are solely actuated by love of office. 'No doubt about it,' replies Thrasymachus. Then why are they paid? Is not the reason, that their interest is not comprehended in their art, and is therefore the concern of another art, the art of pay, which is common to the arts in general, and therefore not identical with any one of them? Nor would any man be a ruler unless he were induced by the hope of reward or the fear of punishment; – the reward is money or honour, the punishment is the necessity of being ruled by a man worse than himself. And if a State (or Church) were composed entirely of good men, they would be affected by the last motive only; and there would be as much 'nolo episcopari' as there is at present of the opposite…
