living in this way we shall have much greater need of physicians than before?
Much greater.
And the country which was enough to support the original inhabitants will be too small now, and not enough?
Quite true.
Then a slice of our neighbours' land will be wanted by us for pasture and tillage, and they will want a slice of ours, if, like ourselves, they exceed the limit of necessity, and give themselves up to the unlimited accumulation of wealth?
That, Socrates, will be inevitable.
And so we shall go to war, Glaucon. Shall we not?
Most certainly, he replied.
Then without determining as yet whether war does good or harm, thus much we may affirm, that now we have discovered war to be derived from causes which are also the causes of almost all the evils in States, private as well as public.
Undoubtedly.
And our State must once more enlarge; and this time the will be nothing short of a whole army, which will have to go out and fight with the invaders for all that we have, as well as for the things and persons whom we were describing above.
Why? he said; are they not capable of defending themselves?
No, I said; not if we were right in the principle which was acknowledged by all of us when we were framing the State: the principle, as you will remember, was that one man cannot practise many arts with success.
Very true, he said.
But is not war an art?
Certainly.
And an art requiring as much attention as shoemaking?
Quite true.
And the shoemaker was not allowed by us to be husbandman, or a weaver, a builder—in order that we might have our shoes well made; but to him and to every other worker was assigned one work for which he was by nature fitted, and at that he was to continue working all his life long and at no other; he was not to let opportunities slip, and then he would become a good workman. Now nothing can be more important than that the work of a soldier should be well done. But is war an art so easily acquired that a man may be a warrior who is also a husbandman, or shoemaker, or other artisan; although no one in the world would be a good dice or draught player who merely took up the game as a recreation, and had not from his earliest years devoted himself to this and nothing else?
No tools will make a man a skilled workman, or master of defence, nor be of any use to him who has not learned how to handle them, and has never bestowed any attention upon them. How then will he who takes up a shield or other implement of war become a good fighter all in a day, whether with heavy-armed or any other kind of troops?
Yes, he said, the tools which would teach men their own use would be beyond price.
And the higher the duties of the guardian, I said, the more time, and skill, and art, and application will be needed by him?
No doubt, he replied.
Will he not also require natural aptitude for his calling?
Certainly.
Then it will be our duty to select, if we can, natures which are fitted for the task of guarding the city?
It will.
And the selection will be no easy matter, I said; but we must be brave and do our best.
We must.
Is not the noble youth very like a well-bred dog in respect of guarding and watching?
What do you mean?
I mean that both of them ought to be quick to see, and swift to overtake the enemy when they see him; and strong too if, when they have caught him, they have to fight with him.
All these qualities, he replied, will certainly be required by them.
Well, and your guardian must be brave if he is to fight well?
Certainly.
And is he likely to be brave who has no spirit, whether horse or dog or any other animal? Have you never observed how invincible and unconquerable is spirit and how the presence of it makes the soul of any creature to be absolutely fearless and indomitable?
I have.
Then now we have a clear notion of the bodily qualities which are required in the guardian.
True.
And also of the mental ones; his soul is to be full of spirit?
Yes.
But are not these spirited natures apt to be savage with one another, and with everybody else?
A difficulty by no means easy to overcome, he replied.
Whereas, I said, they ought to be dangerous to their enemies, and gentle to their friends; if not, they will destroy themselves without waiting for their enemies to destroy them.
True, he said.
What is to be done then? I said; how shall we find a gentle nature which has also a great spirit, for the one is the contradiction of the other?
True.
He will not be a good guardian who is wanting in either of these two qualities; and yet the combination of them appears to be impossible; and hence we must infer that to be a good guardian is impossible.
I am afraid that what you say is true, he replied.
Here feeling perplexed I began to think over what had preceded. My friend, I said, no wonder that we are in a perplexity; for we have lost sight of the image which we had before us.
What do you mean? he said.
I mean to say that there do exist natures gifted with those opposite qualities.
And where do you find them?
Many animals, I replied, furnish examples of them; our friend the dog is a very good one: you know that well-bred dogs are perfectly gentle to their familiars and acquaintances, and the reverse to strangers.
Yes, I know.
Then there is nothing impossible or out of the order of nature in our finding a guardian who has a similar combination of qualities?
Certainly not.
Would not he who is fitted to be a guardian, besides the spirited nature, need to have the qualities of a philosopher?
I do not apprehend your meaning.
The trait of which I am speaking, I replied, may be also seen in the dog, and is remarkable in the animal.
What trait?
Why, a dog, whenever he sees a stranger, is angry; when an acquaintance, he welcomes him, although the one has never done him any harm, nor the other any good. Did this never strike you as curious?
The matter never struck me before; but I quite recognise the truth of your remark.
And surely this instinct of the dog is very charming;—your dog is a true philosopher.
Why?
Why, because he distinguishes the face of a friend and of an enemy only by the criterion of knowing and not knowing. And must not an animal be a lover of learning who determines what he likes and dislikes by the test of knowledge and ignorance?
Most assuredly.
And is not the love of learning the love of wisdom, which is philosophy?
They are the same, he replied.
And may we not say confidently of man also, that he who is likely to be gentle to his friends and acquaintances, must by nature be a lover of wisdom and knowledge?
That we may safely affirm.
