BOOK VII

SOCRATES - GLAUCON

AND now, I said, let me show in a figure how far our nature is

enlightened or unenlightened:--Behold! human beings living in a

underground den, which has a mouth open towards the light and reaching

all along the den; here they have been from their childhood, and have

their legs and necks chained so that they cannot move, and can only see

before them, being prevented by the chains from turning round their

heads. Above and behind them a fire is blazing at a distance, and

between the fire and the prisoners there is a raised way; and you will

see, if you look, a low wall built along the way, like the screen which

marionette players have in front of them, over which they show the

puppets.

I see.

And do you see, I said, men passing along the wall carrying all sorts

of vessels, and statues and figures of animals made of wood and stone

and various materials, which appear over the wall? Some of them are

talking, others silent.

You have shown me a strange image, and they are strange prisoners.

Like ourselves, I replied; and they see only their own shadows, or the

shadows of one another, which the fire throws on the opposite wall of

the cave?

True, he said; how could they see anything but the shadows if they were

never allowed to move their heads?

And of the objects which are being carried in like manner they would

only see the shadows?

Yes, he said.

And if they were able to converse with one another, would they not

suppose that they were naming what was actually before them?

Very true.

And suppose further that the prison had an echo which came from the

other side, would they not be sure to fancy when one of the passers-by

spoke that the voice which they heard came from the passing shadow?

No question, he replied.

To them, I said, the truth would be literally nothing but the shadows

of the images.

That is certain.

And now look again, and see what will naturally follow it' the

prisoners are released and disabused of their error. At first, when

any of them is liberated and compelled suddenly to stand up and turn

his neck round and walk and look towards the light, he will suffer

sharp pains; the glare will distress him, and he will be unable to see

the realities of which in his former state he had seen the shadows; and

then conceive some one saying to him, that what he saw before was an

illusion, but that now, when he is approaching nearer to being and his

eye is turned towards more real existence, he has a clearer vision,

what will be his reply? And you may further imagine that his

instructor is pointing to the objects as they pass and requiring him to

name them,--will he not be perplexed? Will he not fancy that the

shadows which he formerly saw are truer than the objects which are now

shown to him?

Far truer.

And if he is compelled to look straight at the light, will he not have

a pain in his eyes which will make him turn away to take and take in

the objects of vision which he can see, and which he will conceive to

be in reality clearer than the things which are now being shown to him?

True, he now

And suppose once more, that he is reluctantly dragged up a steep and

rugged ascent, and held fast until he's forced into the presence of the

sun himself, is he not likely to be pained and irritated? When he

approaches the light his eyes will be dazzled, and he will not be able

to see anything at all of what are now called realities.

Not all in a moment, he said.

He will require to grow accustomed to the sight of the upper world.

And first he will see the shadows best, next the reflections of men and

other objects in the water, and then the objects themselves; then he

will gaze upon the light of the moon and the stars and the spangled

heaven; and he will see the sky and the stars by night better than the

sun or the light of the sun by day?

Certainly.

Last of he will be able to see the sun, and not mere reflections of him

in the water, but he will see him in his own proper place, and not in

another; and he will contemplate him as he is.

Certainly.

He will then proceed to argue that this is he who gives the season and

the years, and is the guardian of all that is in the visible world, and

in a certain way the cause of all things which he and his fellows have

been accustomed to behold?

Clearly, he said, he would first see the sun and then reason about him.

And when he remembered his old habitation, and the wisdom of the den

and his fellow-prisoners, do you not suppose that he would felicitate

himself on the change, and pity them?

Certainly, he would.

And if they were in the habit of conferring honours among themselves on

those who were quickest to observe the passing shadows and to remark

which of them went before, and which followed after, and which were

together; and who were therefore best able to draw conclusions as to

the future, do you think that he would care for such honours and

glories, or envy the possessors of them? Would he not say with Homer,

Better to be the poor servant of a poor master,

and to endure anything, rather than think as they do and live after

their manner?

Yes, he said, I think that he would rather suffer anything than

entertain these false notions and live in this miserable manner.

Imagine once more, I said, such an one coming suddenly out of the sun

to be replaced in his old situation; would he not be certain to have

his eyes full of darkness?

To be sure, he said.

And if there were a contest, and he had to compete in measuring the

shadows with the prisoners who had never moved out of the den, while

his sight was still weak, and before his eyes had become steady (and

the time which would be needed to acquire this new habit of sight might

be very considerable) would he not be ridiculous? Men would say of him

that up he went and down he came without his eyes; and that it was

better not even to think of ascending; and if any one tried to loose

another and lead him up to the light, let them only catch the offender,

and they would put him to death.

No question, he said.

This entire allegory, I said, you may now append, dear Glaucon, to the

previous argument; the prison-house is the world of sight, the light of

the fire is the sun, and you will not misapprehend me if you interpret

the journey upwards to be the ascent of the soul into the intellectual

world according to my poor belief, which, at your desire, I have

expressed whether rightly or wrongly God knows. But, whether true or

false, my opinion is that in the world of knowledge the idea of good

appears last of all, and is seen only with an effort; and, when seen,

is also inferred to be the universal author of all things beautiful and

right, parent of light and of the lord of light in this visible world,

and the immediate source of reason and truth in the intellectual; and

that this is the power upon which he who would act rationally, either

in public or private life must have his eye fixed.

I agree, he said, as far as I am able to understand you.

Moreover, I said, you must not wonder that those who attain to this

beatific vision are unwilling to descend to human affairs; for their

souls are ever hastening into the upper world where they desire to

dwell; which desire of theirs is very natural, if our allegory may be

trusted.

Yes, very natural.

And is there anything surprising in one who passes from divine

contemplations to the evil state of man, misbehaving himself in a

ridiculous manner; if, while his eyes are blinking and before he has

become accustomed to the surrounding darkness, he is compelled to fight

in courts of law, or in other places, about the images or the shadows

of images of justice, and is endeavouring to meet the conceptions of

those who have never yet seen absolute justice?

Anything but surprising, he replied.

Any one who has common sense will remember that the bewilderments of

the eyes are of two kinds, and arise from two causes, either from

coming out of the light or from going into the light, which is true of

the mind's eye, quite as much as of the bodily eye; and he who

remembers this when he sees any one whose vision is perplexed and weak,

will not be too ready to laugh; he will first ask whether that soul of

man has come out of the brighter light, and is unable to see because

unaccustomed to the dark, or having turned from darkness to the day is

dazzled by excess of light. And he will count the one happy in his

condition and state of being, and he will pity the other; or, if he

have a mind to laugh at the soul which comes from below into the light,

there will be more reason in this than in the laugh which greets him

who returns from above out of the light into the den.

That, he said, is a very just distinction.

But then, if I am right, certain professors of education must be wrong

when they say that they can put a knowledge into the soul which was not

there before, like sight into blind eyes.

They undoubtedly say this, he replied.

Whereas, our argument shows that the power and capacity of learning

exists in the soul already; and that just as the eye was unable to turn

from darkness to light without the whole body, so too the instrument of

knowledge can only by the movement of the whole soul be turned from the

world of becoming into that of being, and learn by degrees to endure

the sight of being, and of the brightest and best of being, or in other

words, of the good.

Very true.

And must there not be some art which will effect conversion in the

easiest and quickest manner; not implanting the faculty of sight, for

that exists already, but has been turned in the wrong direction, and is

looking away from the truth?

Yes, he said, such an art may be presumed.

And whereas the other so-called virtues of the soul seem to be akin to

bodily qualities, for even when they are not originally innate they can

be implanted later by habit and exercise, the of wisdom more than

anything else contains a divine element which always remains, and by

this conversion is rendered useful and profitable; or, on the other

hand, hurtful and useless. Did you never observe the narrow

intelligence flashing from the keen eye of a clever rogue--how eager he

is, how clearly his paltry soul sees the way to his end; he is the

reverse of blind, but his keen eyesight is forced into the service of

evil, and he is mischievous in proportion to his cleverness.

Very true, he said.

But what if there had been a circumcision of such natures in the days

of their youth; and they had been severed from those sensual pleasures,

such as eating and drinking, which, like leaden weights, were attached

to them at their birth, and which drag them down and turn the vision of

their souls upon the things that are below--if, I say, they had been

released from these impediments and turned in the opposite direction,

the very same faculty in them would have seen the truth as keenly as

they see what their eyes are turned to now.

Very likely.

Yes, I said; and there is another thing which is likely, or rather a

necessary inference from what has preceded, that neither the uneducated

and uninformed of the truth, nor yet those who never make an end of

their education, will be able ministers of State; not the former,

because they have no single aim of duty which is the rule of all their

actions, private as well as public; nor the latter, because they will

not act at all except upon compulsion, fancying that they are already

dwelling apart in the islands of the blest.

Very true, he replied.

Then, I said, the business of us who are the founders of the State will

be to compel the best minds to attain that knowledge which we have

already shown to be the greatest of all-they must continue to ascend

until they arrive at the good; but when they have ascended and seen

enough we must not allow them to do as they do now.

What do you mean?

I mean that they remain in the upper world: but this must not be

allowed; they must be made to descend again among the prisoners in the

den, and partake of their labours and honours, whether they are worth

having or not.

But is not this unjust? he said; ought we to give them a worse life,

when they might have a better?

You have again forgotten, my friend, I said, the intention of the

legislator, who did not aim at making any one class in the State happy

above the rest; the happiness was to be in the whole State, and he held

the citizens together by persuasion and necessity, making them

benefactors of the State, and therefore benefactors of one another; to

this end he created them, not to please themselves, but to be his

instruments in binding up the State.

True, he said, I had forgotten.

Observe, Glaucon, that there will be no injustice in compelling our

philosophers to have a care and providence of others; we shall explain

to them that in other States, men of their class are not obliged to

share in the toils of politics: and this is reasonable, for they grow

up at their own sweet will, and the government would rather not have

them. Being self-taught, they cannot be expected to show any gratitude

for a culture which they have never received. But we have brought you

into the world to be rulers of the hive, kings of yourselves and of the

other citizens, and have educated you far better and more perfectly

than they have been educated, and you are better able to share in the

double duty. Wherefore each of you, when his turn comes, must go down

to the general underground abode, and get the habit of seeing in the

dark. When you have acquired the habit, you will see ten thousand

times better than the inhabitants of the den, and you will know what

the several images are, and what they represent, because you have seen

the beautiful and just and good in their truth. And thus our State

which is also yours will be a reality, and not a dream only, and will

be administered in a spirit unlike that of other States, in which men

fight with one another about shadows only and are distracted in the

struggle for power, which in their eyes is a great good. Whereas the

truth is that the State in which the rulers are most reluctant to

govern is always the best and most quietly governed, and the State in

which they are most eager, the worst.

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 the' 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, 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,

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 every one 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 the 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? And if that is true, what sort of general must he

have been?

I should say a very strange one, if this was as you say.

Can we deny that a warrior should have a knowledge of arithmetic?

Certainly he should, if he is to have the smallest understanding of

military tactics, or indeed, I should rather say, if he is to be a man

at all.

I should like to know whether you have the same notion which I have of

this study?

What is your notion?

It appears to me to be a study of the kind which we are seeking, and

which leads naturally to reflection, but never to have been rightly

used; for the true use of it is simply to draw the soul towards being.

Will you explain your meaning? he said.

I will try, I said; and I wish you would share the enquiry with me, and

say 'yes' or 'no' when I attempt to distinguish in my own mind what

branches of knowledge have this attracting power, in order that we may

have clearer proof that arithmetic is, as I suspect, one of them.

Explain, he said.

I mean to say that objects of sense are of two kinds; some of them do

not invite thought because the sense is an adequate judge of them;

while in the case of other objects sense is so untrustworthy that

further enquiry is imperatively demanded.

You are clearly referring, he said, to the manner in which the senses

are imposed upon by distance, and by painting in light and shade.

No, I said, that is not at all my meaning.

Then what is your meaning?

When speaking of uninviting objects, I mean those which do not pass

from one sensation to the opposite; inviting objects are those which

do; in this latter case the sense coming upon the object, whether at a

distance or near, gives no more vivid idea of anything in particular

than of its opposite. An illustration will make my meaning

clearer:--here are three fingers--a little finger, a second finger, and

a middle finger.

Very good.

You may suppose that they are seen quite close: And here comes the

point.

What is it?

Each of them equally appears a finger, whether seen in the middle or at

the extremity, whether white or black, or thick or thin--it makes no

difference; a finger is a finger all the same. In these cases a man is

not compelled to ask of thought the question, what is a finger? for the

sight never intimates to the mind that a finger is other than a finger.

True.

And therefore, I said, as we might expect, there is nothing here which

invites or excites intelligence.

There is not, he said.

But is this equally true of the greatness and smallness of the fingers?

Can sight adequately perceive them? and is no difference made by the

circumstance that one of the fingers is in the middle and another at

the extremity? And in like manner does the touch adequately perceive

the qualities of thickness or thinness, or softness or hardness? And

so of the other senses; do they give perfect intimations of such

matters? Is not their mode of operation on this wise--the sense which

is concerned with the quality of hardness is necessarily concerned also

with the quality of softness, and only intimates to the soul that the

same thing is felt to be both hard and soft?

You are quite right, he said.

And must not the soul be perplexed at this intimation which the sense

gives of a hard which is also soft? What, again, is the meaning of

light and heavy, if that which is light is also heavy, and that which

is heavy, light?

Yes, he said, these intimations which the soul receives are very

curious and require to be explained.

Yes, I said, and in these perplexities the soul naturally summons to

her aid calculation and intelligence, that she may see whether the

several objects announced to her are one or two.

True.

And if they turn out to be two, is not each of them one and different?

Certainly.

And if each is one, and both are two, she will conceive the two as in a

state of division, for if there were undivided they could only be

conceived of as one?

True.

The eye certainly did see both small and great, but only in a confused

manner; they were not distinguished.

Yes.

Whereas the thinking mind, intending to light up the chaos, was

compelled to reverse the process, and look at small and great as

separate and not confused.

Very true.

Was not this the beginning of the enquiry 'What is great?' and 'What is

small?'

Exactly so.

And thus arose the distinction of the visible and the intelligible.

Most true.

This was what I meant when I spoke of impressions which invited the

intellect, or the reverse--those which are simultaneous with opposite

impressions, invite thought; those which are not simultaneous do not.

I understand, he said, and agree with you.

And to which class do unity and number belong?

I do not know, he replied.

Think a little and you will see that what has preceded will supply the

answer; for if simple unity could be adequately perceived by the sight

or by any other sense, then, as we were saying in the case of the

finger, there would be nothing to attract towards being; but when there

is some contradiction always present, and one is the reverse of one and

involves the conception of plurality, then thought begins to be aroused

within us, and the soul perplexed and wanting to arrive at a decision

asks 'What is absolute unity?' This is the way in which the study of

the one has a power of drawing and converting the mind to the

contemplation of true being.

And surely, he said, this occurs notably in the case of one; for we see

the same thing to be both one and infinite in multitude?

Yes, I said; and this being true of one must be equally true of all

number?

Certainly.

And all arithmetic and calculation have to do with number?

Yes.

And they appear to lead the mind towards truth?

Yes, in a very remarkable manner.

Then this is knowledge of the kind for which we are seeking, having a

double use, military and philosophical; for the man of war must learn

the art of number or he will not know how to array his troops, and the

philosopher also, because he has to rise out of the sea of change and

lay hold of true being, and therefore he must be an arithmetician.

That is true.

And our guardian is both warrior and philosopher?

Certainly.

Then this is a kind of knowledge which legislation may fitly prescribe;

and we must endeavour to persuade those who are prescribe to be the

principal men of our State to go and learn arithmetic, not as amateurs,

but they must carry on the study until they see the nature of numbers

with the mind only; nor again, like merchants or retail-traders, with a

view to buying or selling, but for the sake of their military use, and

of the soul herself; and because this will be the easiest way for her

to pass from becoming to truth and being.

That is excellent, he said.

Yes, I said, and now having spoken of it, I must add how charming the

science is! and in how many ways it conduces to our desired end, if

pursued in the spirit of a philosopher, and not of a shopkeeper!

How do you mean?

I mean, as I was saying, that arithmetic has a very great and elevating

effect, compelling the soul to reason about abstract number, and

rebelling against the introduction of visible or tangible objects into

the argument. You know how steadily the masters of the art repel and

ridicule any one who attempts to divide absolute unity when he is

calculating, and if you divide, they multiply, taking care that one

shall continue one and not become lost in fractions.

That is very true.

Now, suppose a person were to say to them: O my friends, what are

these wonderful numbers about which you are reasoning, in which, as you

say, there is a unity such as you demand, and each unit is equal,

invariable, indivisible,--what would they answer?

They would answer, as I should conceive, that they were speaking of

those numbers which can only be realised in thought.

Then you see that this knowledge may be truly called necessary,

necessitating as it clearly does the use of the pure intelligence in

the attainment of pure truth?

Yes; that is a marked characteristic of it.

And have you further observed, that those who have a natural talent for

calculation are generally quick at every other kind of knowledge; and

even the dull if they have had an arithmetical training, although they

may derive no other advantage from it, always become much quicker than

they would otherwise have been.

Very true, he said.

And indeed, you will not easily find a more difficult study, and not

many as difficult.

You will not.

And, for all these reasons, arithmetic is a kind of knowledge in which

the best natures should be trained, and which must not be given up.

I agree.

Let this then be made one of our subjects of education. And next,

shall we enquire whether the kindred science also concerns us?

You mean geometry?

Exactly so.

Clearly, he said, we are concerned with that part of geometry which

relates to war; for in pitching a camp, or taking up a position, or

closing or extending the lines of an army, or any other military

manoeuvre, whether in actual battle or on a march, it will make all the

difference whether a general is or is not a geometrician.

Yes, I said, but for that purpose a very little of either geometry or

calculation will be enough; the question relates rather to the greater

and more advanced part of geometry--whether that tends in any degree to

make more easy the vision of the idea of good; and thither, as I was

saying, all things tend which compel the soul to turn her gaze towards

that place, where is the full perfection of being, which she ought, by

all means, to behold.

True, he said.

Then if geometry compels us to view being, it concerns us; if becoming

only, it does not concern us?

Yes, that is what we assert.

Yet anybody who has the least acquaintance with geometry will not deny

that such a conception of the science is in flat contradiction to the

ordinary language of geometricians.

How so?

They have in view practice only, and are always speaking? in a narrow

and ridiculous manner, of squaring and extending and applying and the

like--they confuse the necessities of geometry with those of daily

life; whereas knowledge is the real object of the whole science.

Certainly, he said.

Then must not a further admission be made?

What admission?

That the knowledge at which geometry aims is knowledge of the eternal,

and not of aught perishing and transient.

That, he replied, may be readily allowed, and is true.

Then, my noble friend, geometry will draw the soul towards truth, and

create the spirit of philosophy, and raise up that which is now

unhappily allowed to fall down.

Nothing will be more likely to have such an effect.

Then nothing should be more sternly laid down than that the inhabitants

of your fair city should by all means learn geometry. Moreover the

science has indirect effects, which are not small.

Of what kind? he said.

There are the military advantages of which you spoke, I said; and in

all departments of knowledge, as experience proves, any one who has

studied geometry is infinitely quicker of apprehension than one who has

not.

Yes indeed, he said, there is an infinite difference between them.

Then shall we propose this as a second branch of knowledge which our

youth will study?

Let us do so, he replied.

And suppose we make astronomy the third--what do you say?

I am strongly inclined to it, he said; the observation of the seasons

and of months and years is as essential to the general as it is to the

farmer or sailor.

I am amused, I said, at your fear of the world, which makes you guard

against the appearance of insisting upon useless studies; and I quite

admit the difficulty of believing that in every man there is an eye of

the soul which, when by other pursuits lost and dimmed, is by these

purified and re-illumined; and is more precious far than ten thousand

bodily eyes, for by it alone is truth seen. Now there are two classes

of persons: one class of those who will agree with you and will take

your words as a revelation; another class to whom they will be utterly

unmeaning, and who will naturally deem them to be idle tales, for they

see no sort of profit which is to be obtained from them. And therefore

you had better decide at once with which of the two you are proposing

to argue. You will very likely say with neither, and that your chief

aim in carrying on the argument is your own improvement; at the same

time you do not grudge to others any benefit which they may receive.

I think that I should prefer to carry on the argument mainly on my own

behalf.

Then take a step backward, for we have gone wrong in the order of the

sciences.

What was the mistake? he said.

After plane geometry, I said, we proceeded at once to solids in

revolution, instead of taking solids in themselves; whereas after the

second dimension the third, which is concerned with cubes and

dimensions of depth, ought to have followed.

That is true, Socrates; but so little seems to be known as yet about

these subjects.

Why, yes, I said, and for two reasons:--in the first place, no

government patronises them; this leads to a want of energy in the

pursuit of them, and they are difficult; in the second place, students

cannot learn them unless they have a director. But then a director can

hardly be found, and even if he could, as matters now stand, the

students, who are very conceited, would not attend to him. That,

however, would be otherwise if the whole State became the director of

these studies and gave honour to them; then disciples would want to

come, and there would be continuous and earnest search, and discoveries

would be made; since even now, disregarded as they are by the world,

and maimed of their fair proportions, and although none of their

votaries can tell the use of them, still these studies force their way

by their natural charm, and very likely, if they had the help of the

State, they would some day emerge into light.

Yes, he said, there is a remarkable charm in them. But I do not

clearly understand the change in the order. First you began with a

geometry of plane surfaces?

Yes, I said.

And you placed astronomy next, and then you made a step backward?

Yes, and I have delayed you by my hurry; the ludicrous state of solid

geometry, which, in natural order, should have followed, made me pass

over this branch and go on to astronomy, or motion of solids.

True, he said.

Then assuming that the science now omitted would come into existence if

encouraged by the State, let us go on to astronomy, which will be

fourth.

The right order, he replied. And now, Socrates, as you rebuked the

vulgar manner in which I praised astronomy before, my praise shall be

given in your own spirit. For every one, as I think, must see that

astronomy compels the soul to look upwards and leads us from this world

to another.

Every one but myself, I said; to every one else this may be clear, but

not to me.

And what then would you say?

I should rather say that those who elevate astronomy into philosophy

appear to me to make us look downwards and not upwards.

What do you mean? he asked.

You, I replied, have in your mind a truly sublime conception of our

knowledge of the things above. And I dare say that if a person were to

throw his head back and study the fretted ceiling, you would still

think that his mind was the percipient, and not his eyes. And you are

very likely right, and I may be a simpleton: but, in my opinion, that

knowledge only which is of being and of the unseen can make the soul

look upwards, and whether a man gapes at the heavens or blinks on the

ground, seeking to learn some particular of sense, I would deny that he

can learn, for nothing of that sort is matter of science; his soul is

looking downwards, not upwards, whether his way to knowledge is by

water or by land, whether he floats, or only lies on his back.

I acknowledge, he said, the justice of your rebuke. Still, I should

like to ascertain how astronomy can be learned in any manner more

conducive to that knowledge of which we are speaking?

I will tell you, I said: The starry heaven which we behold is wrought

upon a visible ground, and therefore, although the fairest and most

perfect of visible things, must necessarily be deemed inferior far to

the true motions of absolute swiftness and absolute slowness, which are

relative to each other, and carry with them that which is contained in

them, in the true number and in every true figure. Now, these are to

be apprehended by reason and intelligence, but not by sight.

True, he replied.

The spangled heavens should be used as a pattern and with a view to

that higher knowledge; their beauty is like the beauty of figures or

pictures excellently wrought by the hand of Daedalus, or some other

great artist, which we may chance to behold; any geometrician who saw

them would appreciate the exquisiteness of their workmanship, but he

would never dream of thinking that in them he could find the true equal

or the true double, or the truth of any other proportion.

No, he replied, such an idea would be ridiculous.

And will not a true astronomer have the same feeling when he looks at

the movements of the stars? Will he not think that heaven and the

things in heaven are framed by the Creator of them in the most perfect

manner? But he will never imagine that the proportions of night and

day, or of both to the month, or of the month to the year, or of the

stars to these and to one another, and any other things that are

material and visible can also be eternal and subject to no

deviation--that would be absurd; and it is equally absurd to take so

much pains in investigating their exact truth.

I quite agree, though I never thought of this before.

Then, I said, in astronomy, as in geometry, we should employ problems,

and let the heavens alone if we would approach the subject in the right

way and so make the natural gift of reason to be of any real use.

That, he said, is a work infinitely beyond our present astronomers.

Yes, I said; and there are many other things which must also have a

similar extension given to them, if our legislation is to be of any

value. But can you tell me of any other suitable study?

No, he said, not without thinking.

Motion, I said, has many forms, and not one only; two of them are

obvious enough even to wits no better than ours; and there are others,

as I imagine, which may be left to wiser persons.

But where are the two?

There is a second, I said, which is the counterpart of the one already

named.

And what may that be?

The second, I said, would seem relatively to the ears to be what the

first is to the eyes; for I conceive that as the eyes are designed to

look up at the stars, so are the ears to hear harmonious motions; and

these are sister sciences--as the Pythagoreans say, and we, Glaucon,

agree with them?

Yes, he replied.

But this, I said, is a laborious study, and therefore we had better go

and learn of them; and they will tell us whether there are any other

applications of these sciences. At the same time, we must not lose

sight of our own higher object.

What is that?

There is a perfection which all knowledge ought to reach, and which our

pupils ought also to attain, and not to fall short of, as I was saying

that they did in astronomy. For in the science of harmony, as you

probably know, the same thing happens. The teachers of harmony compare

the sounds and consonances which are heard only, and their labour, like

that of the astronomers, is in vain.

Yes, by heaven! he said; and 'tis as good as a play to hear them

talking about their condensed notes, as they call them; they put their

ears close alongside of the strings like persons catching a sound from

their neighbour's wall--one set of them declaring that they distinguish

an intermediate note and have found the least interval which should be

the unit of measurement; the others insisting that the two sounds have

passed into the same--either party setting their ears before their

understanding.

You mean, I said, those gentlemen who tease and torture the strings and

rack them on the pegs of the instrument: might carry on the metaphor

and speak after their manner of the blows which the plectrum gives, and

make accusations against the strings, both of backwardness and

forwardness to sound; but this would be tedious, and therefore I will

only say that these are not the men, and that I am referring to the

Pythagoreans, of whom I was just now proposing to enquire about

harmony. For they too are in error, like the astronomers; they

investigate the numbers of the harmonies which are heard, but they

never attain to problems-that is to say, they never reach the natural

harmonies of number, or reflect why some numbers are harmonious and

others not.

That, he said, is a thing of more than mortal knowledge.

A thing, I replied, which I would rather call useful; that is, if

sought after with a view to the beautiful and good; but if pursued in

any other spirit, useless. Very true, he said.

Now, when all these studies reach the point of inter-communion and

connection with one another, and come to be considered in their mutual

affinities, then, I think, but not till then, will the pursuit of them

have a value for our objects; otherwise there is no profit in them.

I suspect so; but you are speaking, Socrates, of a vast work.

What do you mean? I said; the prelude or what? Do you not know that

all this is but the prelude to the actual strain which we have to

learn? For you surely would not regard the skilled mathematician as a

dialectician?

Assuredly not, he said; I have hardly ever known a mathematician who

was capable of reasoning.

But do you imagine that men who are unable to give and take a reason

will have the knowledge which we require of them?

Neither can this be supposed.

And so, Glaucon, I said, we have at last arrived at the hymn of

dialectic. This is that strain which is of the intellect only, but

which the faculty of sight will nevertheless be found to imitate; for

sight, as you may remember, was imagined by us after a while to behold

the real animals and stars, and last of all the sun himself. And so

with dialectic; when a person starts on the discovery of the absolute

by the light of reason only, and without any assistance of sense, and

perseveres until by pure intelligence he arrives at the perception of

the absolute good, he at last finds himself at the end of the

intellectual world, as in the case of sight at the end of the visible.

Exactly, he said.

Then this is the progress which you call dialectic?

True.

But the release of the prisoners from chains, and their translation

from the shadows to the images and to the light, and the ascent from

the underground den to the sun, while in his presence they are vainly

trying to look on animals and plants and the light of the sun, but are

able to perceive even with their weak eyes the images in the water

(which are divine), and are the shadows of true existence (not shadows

of images cast by a light of fire, which compared with the sun is only

an image)--this power of elevating the highest principle in the soul to

the contemplation of that which is best in existence, with which we may

compare the raising of that faculty which is the very light of the body

to the sight of that which is brightest in the material and visible

world--this power is given, as I was saying, by all that study and

pursuit of the arts which has been described.

I agree in what you are saying, he replied, which may be hard to

believe, yet, from another point of view, is harder still to deny.

This, however, is not a theme to be treated of in passing only, but

will have to be discussed again and again. And so, whether our

conclusion be true or false, let us assume all this, and proceed at

once from the prelude or preamble to the chief strain, and describe

that in like manner. Say, then, what is the nature and what are the

divisions of dialectic, and what are the paths which lead thither; for

these paths will also lead to our final rest?

Dear Glaucon, I said, you will not be able to follow me here, though I

would do my best, and you should behold not an image only but the

absolute truth, according to my notion. Whether what I told you would

or would not have been a reality I cannot venture to say; but you would

have seen something like reality; of that I am confident.

Doubtless, he replied.

But I must also remind you, that the power of dialectic alone can

reveal this, and only to one who is a disciple of the previous sciences.

Of that assertion you may be as confident as of the last.

And assuredly no one will argue that there is any other method of

comprehending by any regular process all true existence or of

ascertaining what each thing is in its own nature; for the arts in

general are concerned with the desires or opinions of men, or are

cultivated with a view to production and construction, or for the

preservation of such productions and constructions; and as to the

mathematical sciences which, as we were saying, have some apprehension

of true being--geometry and the like--they only dream about being, but

never can they behold the waking reality so long as they leave the

hypotheses which they use unexamined, and are unable to give an account

of them. For when a man knows not his own first principle, and when

the conclusion and intermediate steps are also constructed out of he

knows not what, how can he imagine that such a fabric of convention can

ever become science?

Impossible, he said.

Then dialectic, and dialectic alone, goes directly to the first

principle and is the only science which does away with hypotheses in

order to make her ground secure; the eye of the soul, which is

literally buried in an outlandish slough, is by her gentle aid lifted

upwards; and she uses as handmaids and helpers in the work of

conversion, the sciences which we have been discussing. Custom terms

them sciences, but they ought to have some other name, implying greater

clearness than opinion and less clearness than science: and this, in

our previous sketch, was called understanding. But why should we

dispute about names when we have realities of such importance to

consider?

Why indeed, he said, when any name will do which expresses the thought

of the mind with clearness?

At any rate, we are satisfied, as before, to have four divisions; two

for intellect and two for opinion, and to call the first division

science, the second understanding, the third belief, and the fourth

perception of shadows, opinion being concerned with becoming, and

intellect with being; and so to make a proportion:--

As being is to becoming, so is pure intellect to opinion.

And as intellect is to opinion, so is science to belief, and

understanding to the perception of shadows.

But let us defer the further correlation and subdivision of the

subjects of opinion and of intellect, for it will be a long enquiry,

many times longer than this has been.

As far as I understand, he said, I agree.

And do you also agree, I said, in describing the dialectician as one

who attains a conception of the essence of each thing? And he who does

not possess and is therefore unable to impart this conception, in

whatever degree he fails, may in that degree also be said to fail in

intelligence? Will you admit so much?

Yes, he said; how can I deny it?

And you would say the same of the conception of the good?

Until the person is able to abstract and define rationally the idea of

good, and unless he can run the gauntlet of all objections, and is

ready to disprove them, not by appeals to opinion, but to absolute

truth, never faltering at any step of the argument--unless he can do

all this, you would say that he knows neither the idea of good nor any

other good; he apprehends only a shadow, if anything at all, which is

given by opinion and not by science;--dreaming and slumbering in this

life, before he is well awake here, he arrives at the world below, and

has his final quietus.

In all that I should most certainly agree with you.

And surely you would not have the children of your ideal State, whom

you are nurturing and educating--if the ideal ever becomes a

reality--you would not allow the future rulers to be like posts, having

no reason in them, and yet to be set in authority over the highest

matters?

Certainly not.

Then you will make a law that they shall have such an education as will

enable them to attain the greatest skill in asking and answering

questions?

Yes, he said, you and I together will make it.

Dialectic, then, as you will agree, is the coping-stone of the

sciences, and is set over them; no other science can be placed

higher--the nature of knowledge can no further go?

I agree, he said.

But to whom we are to assign these studies, and in what way they are to

be assigned, are questions which remain to be considered?

Yes, clearly.

You remember, I said, how the rulers were chosen before?

Certainly, he said.

The same natures must still be chosen, and the preference again given

to the surest and the bravest, and, if possible, to the fairest; and,

having noble and generous tempers, they should also have the natural

gifts which will facilitate their education.

And what are these?

Such gifts as keenness and ready powers of acquisition; for the mind

more often faints from the severity of study than from the severity of

gymnastics: the toil is more entirely the mind's own, and is not

shared with the body.

Very true, he replied.

Further, he of whom we are in search should have a good memory, and be

an unwearied solid man who is a lover of labour in any line; or he will

never be able to endure the great amount of bodily exercise and to go

through all the intellectual discipline and study which we require of

him.

Certainly, he said; he must have natural gifts.

The mistake at present is, that those who study philosophy have no

vocation, and this, as I was before saying, is the reason why she has

fallen into disrepute: her true sons should take her by the hand and

not bastards.

What do you mean?

In the first place, her votary should not have a lame or halting

industry--I mean, that he should not be half industrious and half idle:

as, for example, when a man is a lover of gymnastic and hunting, and

all other bodily exercises, but a hater rather than a lover of the

labour of learning or listening or enquiring. Or the occupation to

which he devotes himself may be of an opposite kind, and he may have

the other sort of lameness.

Certainly, he said.

And as to truth, I said, is not a soul equally to be deemed halt and

lame which hates voluntary falsehood and is extremely indignant at

herself and others when they tell lies, but is patient of involuntary

falsehood, and does not mind wallowing like a swinish beast in the mire

of ignorance, and has no shame at being detected?

To be sure.

And, again, in respect of temperance, courage, magnificence, and every

other virtue, should we not carefully distinguish between the true son

and the bastard? for where there is no discernment of such qualities

States and individuals unconsciously err and the State makes a ruler,

and the individual a friend, of one who, being defective in some part

of virtue, is in a figure lame or a bastard.

That is very true, he said.

All these things, then, will have to be carefully considered by us; and

if only those whom we introduce to this vast system of education and

training are sound in body and mind, justice herself will have nothing

to say against us, and we shall be the saviours of the constitution and

of the State; but, if our pupils are men of another stamp, the reverse

will happen, and we shall pour a still greater flood of ridicule on

philosophy than she has to endure at present.

That would not be creditable.

Certainly not, I said; and yet perhaps, in thus turning jest into

earnest I am equally ridiculous.

In what respect?

I had forgotten, I said, that we were not serious, and spoke with too

much excitement. For when I saw philosophy so undeservedly trampled

under foot of men I could not help feeling a sort of indignation at the

authors of her disgrace: and my anger made me too vehement.

Indeed! I was listening, and did not think so.

But I, who am the speaker, felt that I was. And now let me remind you

that, although in our former selection we chose old men, we must not do

so in this. Solon was under a delusion when he said that a man when he

grows old may learn many things--for he can no more learn much than he

can run much; youth is the time for any extraordinary toil.

Of course.

And, therefore, calculation and geometry and all the other elements of

instruction, which are a preparation for dialectic, should be presented

to the mind in childhood; not, however, under any notion of forcing our

system of education.

Why not?

Because a freeman ought not to be a slave in the acquisition of

knowledge of any kind. Bodily exercise, when compulsory, does no harm

to the body; but knowledge which is acquired under compulsion obtains

no hold on the mind.

Very true.

Then, my good friend, I said, do not use compulsion, but let early

education be a sort of amusement; you will then be better able to find

out the natural bent.

That is a very rational notion, he said.

Do you remember that the children, too, were to be taken to see the

battle on horseback; and that if there were no danger they were to be

brought close up and, like young hounds, have a taste of blood given

them?

Yes, I remember.

The same practice may be followed, I said, in all these

things--labours, lessons, dangers--and he who is most at home in all of

them ought to be enrolled in a select number.

At what age?

At the age when the necessary gymnastics are over: the period whether

of two or three years which passes in this sort of training is useless

for any other purpose; for sleep and exercise are unpropitious to

learning; and the trial of who is first in gymnastic exercises is one

of the most important tests to which our youth are subjected.

Certainly, he replied.

After that time those who are selected from the class of twenty years

old will be promoted to higher honour, and the sciences which they

learned without any order in their early education will now be brought

together, and they will be able to see the natural relationship of them

to one another and to true being.

Yes, he said, that is the only kind of knowledge which takes lasting

root.

Yes, I said; and the capacity for such knowledge is the great criterion

of dialectical talent: the comprehensive mind is always the

dialectical.

I agree with you, he said.

These, I said, are the points which you must consider; and those who

have most of this comprehension, and who are more steadfast in their

learning, and in their military and other appointed duties, when they

have arrived at the age of thirty have to be chosen by you out of the

select class, and elevated to higher honour; and you will have to prove

them by the help of dialectic, in order to learn which of them is able

to give up the use of sight and the other senses, and in company with

truth to attain absolute being: And here, my friend, great caution is

required.

Why great caution?

Do you not remark, I said, how great is the evil which dialectic has

introduced?

What evil? he said.

The students of the art are filled with lawlessness.

Quite true, he said.

Do you think that there is anything so very unnatural or inexcusable in

their case? or will you make allowance for them?

In what way make allowance?

I want you, I said, by way of parallel, to imagine a supposititious son

who is brought up in great wealth; he is one of a great and numerous

family, and has many flatterers. When he grows up to manhood, he

learns that his alleged are not his real parents; but who the real are

he is unable to discover. Can you guess how he will be likely to

behave towards his flatterers and his supposed parents, first of all

during the period when he is ignorant of the false relation, and then

again when he knows? Or shall I guess for you?

If you please.

Then I should say, that while he is ignorant of the truth he will be

likely to honour his father and his mother and his supposed relations

more than the flatterers; he will be less inclined to neglect them when

in need, or to do or say anything against them; and he will be less

willing to disobey them in any important matter.

He will.

But when he has made the discovery, I should imagine that he would

diminish his honour and regard for them, and would become more devoted

to the flatterers; their influence over him would greatly increase; he

would now live after their ways, and openly associate with them, and,

unless he were of an unusually good disposition, he would trouble

himself no more about his supposed parents or other relations.

Well, all that is very probable. But how is the image applicable to

the disciples of philosophy?

In this way: you know that there are certain principles about justice

and honour, which were taught us in childhood, and under their parental

authority we have been brought up, obeying and honouring them.

That is true.

There are also opposite maxims and habits of pleasure which flatter and

attract the soul, but do not influence those of us who have any sense

of right, and they continue to obey and honour the maxims of their

fathers.

True.

Now, when a man is in this state, and the questioning spirit asks what

is fair or honourable, and he answers as the legislator has taught him,

and then arguments many and diverse refute his words, until he is

driven into believing that nothing is honourable any more than

dishonourable, or just and good any more than the reverse, and so of

all the notions which he most valued, do you think that he will still

honour and obey them as before?

Impossible.

And when he ceases to think them honourable and natural as heretofore,

and he fails to discover the true, can he be expected to pursue any

life other than that which flatters his desires?

He cannot.

And from being a keeper of the law he is converted into a breaker of it?

Unquestionably.

Now all this is very natural in students of philosophy such as I have

described, and also, as I was just now saying, most excusable.

Yes, he said; and, I may add, pitiable.

Therefore, that your feelings may not be moved to pity about our

citizens who are now thirty years of age, every care must be taken in

introducing them to dialectic.

Certainly.

There is a danger lest they should taste the dear delight too early;

for youngsters, as you may have observed, when they first get the taste

in their mouths, argue for amusement, and are always contradicting and

refuting others in imitation of those who refute them; like puppy-dogs,

they rejoice in pulling and tearing at all who come near them.

Yes, he said, there is nothing which they like better.

And when they have made many conquests and received defeats at the

hands of many, they violently and speedily get into a way of not

believing anything which they believed before, and hence, not only

they, but philosophy and all that relates to it is apt to have a bad

name with the rest of the world.

Too true, he said.

But when a man begins to get older, he will no longer be guilty of such

insanity; he will imitate the dialectician who is seeking for truth,

and not the eristic, who is contradicting for the sake of amusement;

and the greater moderation of his character will increase instead of

diminishing the honour of the pursuit.

Very true, he said.

And did we not make special provision for this, when we said that the

disciples of philosophy were to be orderly and steadfast, not, as now,

any chance aspirant or intruder?

Very true.

Suppose, I said, the study of philosophy to take the place of

gymnastics and to be continued diligently and earnestly and exclusively

for twice the number of years which were passed in bodily

exercise--will that be enough?

Would you say six or four years? he asked.

Say five years, I replied; at the end of the time they must be sent

down again into the den and compelled to hold any military or other

office which young men are qualified to hold: in this way they will get

their experience of life, and there will be an opportunity of trying

whether, when they are drawn all manner of ways by temptation, they

will stand firm or flinch.

And how long is this stage of their lives to last?

Fifteen years, I answered; and when they have reached fifty years of

age, then let those who still survive and have distinguished themselves

in every action of their lives and in every branch of knowledge come at

last to their consummation; the time has now arrived at which they must

raise the eye of the soul to the universal light which lightens all

things, and behold the absolute good; for that is the pattern according

to which they are to order the State and the lives of individuals, and

the remainder of their own lives also; making philosophy their chief

pursuit, but, when their turn comes, toiling also at politics and

ruling for the public good, not as though they were performing some

heroic action, but simply as a matter of duty; and when they have

brought up in each generation others like themselves and left them in

their place to be governors of the State, then they will depart to the

Islands of the Blest and dwell there; and the city will give them

public memorials and sacrifices and honour them, if the Pythian oracle

consent, as demi-gods, but if not, as in any case blessed and divine.

You are a sculptor, Socrates, and have made statues of our governors

faultless in beauty.

Yes, I said, Glaucon, and of our governesses too; for you must not

suppose that what I have been saying applies to men only and not to

women as far as their natures can go.

There you are right, he said, since we have made them to share in all

things like the men.

Well, I said, and you would agree (would you not?) that what has been

said about the State and the government is not a mere dream, and

although difficult not impossible, but only possible in the way which

has been supposed; that is to say, when the true philosopher kings are

born in a State, one or more of them, despising the honours of this

present world which they deem mean and worthless, esteeming above all

things right and the honour that springs from right, and regarding

justice as the greatest and most necessary of all things, whose

ministers they are, and whose principles will be exalted by them when

they set in order their own city?

How will they proceed?

They will begin by sending out into the country all the inhabitants of

the city who are more than ten years old, and will take possession of

their children, who will be unaffected by the habits of their parents;

these they will train in their own habits and laws, I mean in the laws

which we have given them: and in this way the State and constitution

of which we were speaking will soonest and most easily attain

happiness, and the nation which has such a constitution will gain most.

Yes, that will be the best way. And I think, Socrates, that you have

very well described how, if ever, such a constitution might come into

being.

Enough then of the perfect State, and of the man who bears its

image--there is no difficulty in seeing how we shall describe him.

There is no difficulty, he replied; and I agree with you in thinking

that nothing more need be said.
