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 recognize 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.
Then he who is to be a really good and noble guardian of the State will require to unite in himself philosophy and spirit and swiftness and strength?
Undoubtedly.
Then we have found the desired natures; and now that we have found them, how are they to be reared and educated? Is not this an inquiry which may be expected to throw light on the greater inquiry which is our final end—How do justice and injustice grow up in States? for we do not want either to omit what is to the point or to draw out the argument to an inconvenient length.
Adeimantus thought that the inquiry would be of great service to us.
Then, I said, my dear friend, the task must not be given up, even if somewhat long.
Certainly not.
Come then, and let us pass a leisure hour in story-telling, and our story shall be the education of our heroes.
