Quite true, he replied.
And will our pupils, when they hear this, refuse to take their turn at the toils of State, when they are allowed to spend the greater part of their time with one another in the heavenly light?
Impossible, he answered; for they are just men, and the commands which we impose upon them are just; there can be no doubt that every one of them will take office as a stern necessity, and not after the fashion of our present rulers of State.
Yes, my friend, I said; and there lies the point. You must contrive for your future rulers another and a better life than that of a ruler, and then you may have a well-ordered State; for only in the State which offers this, will they rule who are truly rich, not in silver and gold, but in virtue and wisdom, which are the true blessings of life. Whereas if they go to the administration of public affairs, poor and hungering after their own private advantage, thinking that hence they are to snatch the chief good, order there can never be; for they will be fighting about office, and the civil and domestic broils which thus arise will be the ruin of the rulers themselves and of the whole State.
Most true, he replied.
And the only life which looks down upon the life of political ambition is that of true philosophy. Do you know of any other?
Indeed, I do not, he said.
And those who govern ought not to be lovers of the task? For, if they are, there will be rival lovers, and they will fight.
No question.
Who then are those whom we shall compel to be guardians? Surely they will be the men who are wisest about affairs of State, and by whom the State is best administered, and who at the same time have other honours and another and a better life than that of politics?
They are the men, and I will choose them, he replied.
And now shall we consider in what way such guardians will be produced, and how they are to be brought from darkness to light—as some are said to have ascended from the world below to the gods?
By all means, he replied.
The process, I said, is not the turning over of an oyster-shell,238 but the turning round of a soul passing from a day which is little better than night to the true day of being, that is, the ascent from below,239 which we affirm to be true philosophy?
Quite so.
And should we not enquire what sort of knowledge has the power of effecting such a change?
Certainly.
What sort of knowledge is there which would draw the soul from becoming to being? And another consideration has just occurred to me: You will remember that our young men are to be warrior athletes?
Yes, that was said.
Then this new kind of knowledge must have an additional quality?
What quality?
Usefulness in war.
Yes, if possible.
There were two parts in our former scheme of education, were there not?
Just so.
There was gymnastic which presided over the growth and decay of the body, and may therefore be regarded as having to do with generation and corruption?
True.
Then that is not the knowledge which we are seeking to discover?
No.
But what do you say of music, which also entered to a certain extent into our former scheme?
Music, he said, as you will remember, was the counterpart of gymnastic, and trained the guardians by the influences of habit, by harmony making them harmonious, by rhythm rhythmical, but not giving them science; and the words, whether fabulous or possibly true, had kindred elements of rhythm and harmony in them. But in music there was nothing which tended to that good which you are now seeking.
You are most accurate, I said, in your recollection; in music there certainly was nothing of the kind. But what branch of knowledge is there, my dear Glaucon, which is of the desired nature; since all the useful arts were reckoned mean by us?
Undoubtedly; and yet if music and gymnastic are excluded, and the arts are also excluded, what remains?
Well, I said, there may be nothing left of our special subjects; and then we shall have to take something which is not special, but of universal application.
What may that be?
A something which all arts and sciences and intelligences use in common, and which everyone first has to learn among the elements of education.
What is that?
The little matter of distinguishing one, two, and three—in a word, number and calculation:—do not all arts and sciences necessarily partake of them?
Yes.
Then the art of war partakes of them?
To be sure.
Then Palamedes, whenever he appears in tragedy, proves Agamemnon ridiculously unfit to be a general. Did you never remark how he declares that he had invented number, and had numbered the ships and set in array the ranks of the army at Troy; which implies that they had never been numbered before, and Agamemnon must be supposed literally to have been incapable of counting his own feet—how could he if he was ignorant of number?
