are severally one, yet in their various combinations appear to be many. Those who recognize these realities are philosophers; whereas the other class hear sounds and see colours, and understand their use in the arts, but cannot attain to the true or waking vision of absolute justice or beauty or truth; they have not the light of knowledge, but of opinion, and what they see is a dream only. Perhaps he of whom we say the last will be angry with us; can we pacify him without revealing the disorder of his mind? Suppose we say that, if he has knowledge we rejoice to hear it, but knowledge must be of something which is, as ignorance is of something which is not; and there is a third thing, which both is and is not, and is matter of opinion only. Opinion and knowledge, then, having distinct objects, must also be distinct faculties. And by faculties I mean powers unseen and distinguishable only by the difference in their objects, as opinion and knowledge differ, since the one is liable to err, but the other is unerring and is the mightiest of all our faculties. If being is the object of knowledge, and not-being of ignorance, and these are the extremes, opinion must lie between them, and may be called darker than the one and brighter than the other. This intermediate or contingent matter is and is not at the same time, and partakes both of existence and of non-existence. Now I would ask my good friend, who denies abstract beauty and justice, and affirms a many beautiful and a many just, whether everything he sees is not in some point of view different – the beautiful ugly, the pious impious, the just unjust? Is not the double also the half, and are not heavy and light relative terms which pass into one another? Everything is and is not, as in the old riddle – 'A man and not a man shot and did not shoot a bird and not a bird with a stone and not a stone.' The mind cannot be fixed on either alternative; and these ambiguous, intermediate, erring, half-lighted objects, which have a disorderly movement in the region between being and not-being, are the proper matter of opinion, as the immutable objects are the proper matter of knowledge. And he who grovels in the world of sense, and has only this uncertain perception of things, is not a philosopher, but a lover of opinion only…
The fifth book is the new beginning of the Republic, in which the community of property and of family are first maintained, and the transition is made to the kingdom of philosophers. For both of these Plato, after his manner, has been preparing in some chance words of Book IV, which fall unperceived on the reader's mind, as they are supposed at first to have fallen on the ear of Glaucon and Adeimantus. The 'paradoxes,' as Morgenstern terms them, of this book of the Republic will be reserved for another place; a few remarks on the style, and some explanations of difficulties, may be briefly added.
First, there is the image of the waves, which serves for a sort of scheme or plan of the book. The first wave, the second wave, the third and greatest wave come rolling in, and we hear the roar of them. All that can be said of the extravagance of Plato's proposals is anticipated by himself. Nothing is more admirable than the hesitation with which he proposes the solemn text, 'Until kings are philosophers,' etc.; or the reaction from the sublime to the ridiculous, when Glaucon describes the manner in which the new truth will be received by mankind.
Some defects and difficulties may be noted in the execution of the communistic plan. Nothing is told us of the application of communism to the lower classes; nor is the table of prohibited degrees capable of being made out. It is quite possible that a child born at one hymeneal festival may marry one of its own brothers or sisters, or even one of its parents, at another. Plato is afraid of incestuous unions, but at the same time he does not wish to bring before us the fact that the city would be divided into families of those born seven and nine months after each hymeneal festival. If it were worth while to argue seriously about such fancies, we might remark that while all the old affinities are abolished, the newly prohibited affinity rests not on any natural or rational principle, but only upon the accident of children having been born in the same month and year. Nor does he explain how the lots could be so manipulated by the legislature as to bring together the fairest and best. The singular expression which is employed to describe the age of five-and-twenty may perhaps be taken from some poet.
In the delineation of the philosopher, the illustrations of the nature of philosophy derived from love are more suited to the apprehension of Glaucon, the Athenian man of pleasure, than to modern tastes or feelings. They are partly facetious, but also contain a germ of truth. That science is a whole, remains a true principle of inductive as well as of metaphysical philosophy; and the love of universal knowledge is still the characteristic of the philosopher in modern as well as in ancient times.
At the end of the fifth book Plato introduces the figment of contingent matter, which has exercised so great an influence both on the Ethics and Theology of the modern world, and which occurs here for the first time in the history of philosophy. He did not remark that the degrees of knowledge in the subject have nothing corresponding to them in the object. With him a word must answer to an idea; and he could not conceive of an opinion which was an opinion about nothing. The influence of analogy led him to invent 'parallels and conjugates' and to overlook facts. To us some of his difficulties are puzzling only from their simplicity: we do not perceive that the answer to them 'is tumbling out at our feet.' To the mind of early thinkers, the conception of not-being was dark and mysterious; they did not see that this terrible apparition which threatened destruction to all knowledge was only a logical determination. The common term under which, through the accidental use of language, two entirely different ideas were included was another source of confusion. Thus through the ambiguity of (Greek) Plato, attempting to introduce order into the first chaos of human thought, seems to have confused perception and opinion, and to have failed to distinguish the contingent from the relative. In the Theaetetus the first of these difficulties begins to clear up; in the Sophist the second; and for this, as well as for other reasons, both these dialogues are probably to be regarded as later than the Republic.
BOOK VI. Having determined that the many have no knowledge of true being, and have no clear patterns in their minds of justice, beauty, truth, and that philosophers have such patterns, we have now to ask whether they or the many shall be rulers in our State. But who can doubt that philosophers should be chosen, if they have the other qualities which are required in a ruler? For they are lovers of the knowledge of the eternal and of all truth; they are haters of falsehood; their meaner desires are absorbed in the interests of knowledge; they are spectators of all time and all existence; and in the magnificence of their contemplation the life of man is as nothing to them, nor is death fearful. Also they are of a social, gracious disposition, equally free from cowardice and arrogance. They learn and remember easily; they have harmonious, well-regulated minds; truth flows to them sweetly by nature. Can the god of Jealousy himself find any fault with such an assemblage of good qualities?
Here Adeimantus interposes: – 'No man can answer you, Socrates; but every man feels that this is owing to his own deficiency in argument. He is driven from one position to another, until he has nothing more to say, just as an unskilful player at draughts is reduced to his last move by a more skilled opponent. And yet all the time he may be right. He may know, in this very instance, that those who make philosophy the business of their lives, generally turn out rogues if they are bad men, and fools if they are good. What do you say?' I should say that he is quite right. 'Then how is such an admission reconcileable with the doctrine that philosophers should be kings?'
I shall answer you in a parable which will also let you see how poor a hand I am at the invention of allegories. The relation of good men to their governments is so peculiar, that in order to defend them I must take an illustration from the world of fiction. Conceive the captain of a ship, taller by a head and shoulders than any of the crew, yet a little deaf, a little blind, and rather ignorant of the seaman's art. The sailors want to steer, although they know nothing of the art; and they have a theory that it cannot be learned. If the helm is refused them, they drug the captain's posset, bind him hand and foot, and take possession of the ship. He who joins in the mutiny is termed a good pilot and what not; they have no conception that the true pilot must observe the winds and the stars, and must be their master, whether they like it or not; – such an one would be called by them fool, prater, star-gazer. This is my parable; which I will beg you to interpret for me to those gentlemen who ask why the philosopher has such an evil name, and to explain to them that not he, but those who will not use him, are to blame for his uselessness. The philosopher should not beg of mankind to be put in authority over them. The wise man should not seek the rich, as the proverb bids, but every man, whether rich or poor, must knock at the door of the physician
