The Republic

Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind.

let me tell you, that the more the pleasures of the body fade away, the greater to me is the pleasure and charm of conversation.

justice is based on the idea of good, which is the harmony of the world, and is reflected both in the institutions of States and in motions of the heavenly bodies.

And is not the love of learning the love of wisdom, which is philosophy?

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.

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 enquiry which may be expected to throw light on the greater enquiry which is our final end--How do justice and injustice grow up in States? for we do not want either to

Again, there is another manner in which, according to Homer, brave youths should be honoured; for he tells how Ajax, after he had distinguished himself in battle, was rewarded with long chines, which seems to be a compliment appropriate to a hero in the flower of his age, being not only a tribute of honour but also a very strengthening thing.

He is answered that justice does good to friends and harm to enemies. But in what way good or harm? 'In making alliances with the one, and going to war with the other.' Then in time of peace what is the good of justice? The answer is that justice is of use in contracts, and contracts are money partnerships. Yes; but how in such partnerships is the just man of more use than any other man? 'When you want to have money safely kept and not used.' Then justice will

hence there arise laws and mutual covenants; and that which is ordained by law is termed by them lawful and just. This they affirm to be the origin and nature of justice;--it is a mean or compromise, between the best of all, which is to do injustice and not be punished, and the worst of all, which is to suffer injustice without the power of retaliation; and justice, being at a middle point between the two, is tolerated not as a good, but as the lesser evil, and honoured by reason of the inability of men to do injustice with impunity.
