The Republic

We have.

Yes; and we had before agreed that anything of this kind which we might find was to be described as matter of opinion, and not as matter of knowledge; being the intermediate flux which is caught and detained by the intermediate faculty.

Quite true.

Then those who see the many beautiful, and who yet neither see absolute beauty, nor can follow any guide who points the way thither; who see the many just, and not absolute justice, and the like, – such persons may be said to have opinion but not knowledge?

That is certain.

But those who see the absolute and eternal and immutable may be said to know, and not to have opinion only?

Neither can that be denied.

The one love and embrace the subjects of knowledge, the other those of opinion? The latter are the same, as I dare say you will remember, who listened to sweet sounds and gazed upon fair colours, but would not tolerate the existence of absolute beauty.

Yes, I remember.

Shall we then be guilty of any impropriety in calling them lovers of opinion rather than lovers of wisdom, and will they be very angry with us for thus describing them?

I shall tell them not to be angry; no man should be angry at what is true.

But those who love the truth in each thing are to be called lovers of wisdom and not lovers of opinion.

Assuredly.

BOOK VI

And thus, Glaucon, after the argument has gone a weary way, the true and the false philosophers have at length appeared in view.

I do not think, he said, that the way could have been shortened.

I suppose not, I said; and yet I believe that we might have had a better view of both of them if the discussion could have been confined to this one subject and if there were not many other questions awaiting us, which he who desires to see in what respect the life of the just differs from that of the unjust must consider.

And what is the next question? he asked.

Surely, I said, the one which follows next in order. Inasmuch as philosophers only are able to grasp the eternal and unchangeable, and those who wander in the region of the many and variable are not philosophers, I must ask you which of the two classes should be the rulers of our State?

And how can we rightly answer that question?

Whichever of the two are best able to guard the laws and institutions of our State – let them be our guardians.

Very good.

Neither, I said, can there be any question that the guardian who is to keep anything should have eyes rather than no eyes?

There can be no question of that.

And are not those who are verily and indeed wanting in the knowledge of the true being of each thing, and who have in their souls no clear pattern, and are unable as with a painter's eye to look at the absolute truth and to that original to repair, and having perfect vision of the other world to order the laws about beauty, goodness, justice in this, if not already ordered, and to guard and preserve the order of them – are not such persons, I ask, simply blind?

Truly, he replied, they are much in that condition.

And shall they be our guardians when there are others who, besides being their equals in experience and falling short of them in no particular of virtue, also know the very truth of each thing?

There can be no reason, he said, for rejecting those who have this greatest of all great qualities; they must always have the first place unless they fail in some other respect.

Suppose then, I said, that we determine how far they can unite this and the other excellences.

By all means.

In the first place, as we began by observing, the nature of the philosopher has to be ascertained. We must come to an understanding about him, and, when we have done so, then, if I am not mistaken, we shall also acknowledge that such an union of qualities is possible, and that those in whom they are united, and those only, should be rulers in the State.

What do you mean?

Let us suppose that philosophical minds always love knowledge of a sort which shows them the eternal nature not varying from generation and corruption.

Agreed.

And further, I said, let us agree that they are lovers of all true being; there is no part whether greater or less, or more or less honourable, which they are willing to renounce; as we said before of the lover and the man of ambition.

True.

And if they are to be what we were describing, is there not another quality which they should also possess?

What quality?

Truthfulness: they will never intentionally receive into their mind falsehood, which is their detestation, and they will love the truth.

Yes, that may be safely affirmed of them.

'May be,' my friend, I replied, is not the word; say rather 'must be affirmed:' for he whose nature is amorous of anything cannot help loving all that belongs or is akin to the object of his affections.

Right, he said.

And is there anything more akin to wisdom than truth?

How can there be?

Can the same nature be a lover of wisdom and a lover of falsehood?

Never.

The true lover of learning then must from his earliest youth, as far as in him lies, desire all truth?

Assuredly.

But then again, as we know by experience, he whose desires are strong in one direction will have them weaker in others; they will be like a stream which has been drawn off into another channel.

True.
