pilot, the general, the physician, we will interrogate the mind of the statesman. Tell me, I say, as the physician and general have told us their object, what is the object of the statesman. Can you tell me? 'We cannot.' Did we not say that there are four virtues--courage, wisdom, and two others, all of which are called by the common name of virtue, and are in a sense one? 'Certainly we did.' The difficulty is, not in understanding the differences of the virtues, but in apprehending their unity. Why do we call virtue, which is a single thing, by the two names of wisdom and courage? The reason is that courage is concerned with fear, and is found both in children and in brutes; for the soul may be courageous without reason, but no soul was, or ever will be, wise without reason. 'That is true.' I have explained to you the difference, and do you in return explain to me the unity. But first let us consider whether any one who knows the name of a thing without the definition has any real knowledge of it. Is not such knowledge a disgrace to a man of sense, especially where great and glorious truths are concerned? and can any subject be more worthy of the attention of our legislators than the four virtues of which we are speaking--courage, temperance, justice, wisdom? Ought not the magistrates and officers of the state to instruct the citizens in the nature of virtue and vice, instead of leaving them to be taught by some chance poet or sophist? A city which is without instruction suffers the usual fate of cities in our day. What then shall we do? How shall we perfect the ideas of our guardians about virtue? how shall we give our state a head and eyes? 'Yes, but how do you apply the figure?' The city will be the body or trunk; the best of our young men will mount into the head or acropolis and be our eyes; they will look about them, and inform the elders, who are the mind and use the younger men as their instruments: together they will save the state. Shall this be our constitution, or shall all be educated alike, and the special training be given up? 'That is impossible.' Let us then endeavour to attain to some more exact idea of education. Did we not say that the true artist or guardian ought to have an eye, not only to the many, but to the one, and to order all things with a view to the one? Can there be any more philosophical speculation than how to reduce many things which are unlike to one idea? 'Perhaps not.' Say rather, 'Certainly not.' And the rulers of our divine state ought to have an exact knowledge of the common principle in courage, temperance, justice, wisdom, which is called by the name of virtue; and unless we know whether virtue is one or many, we shall hardly know what virtue is. Shall we contrive some means of engrafting this knowledge on our state, or give the matter up? 'Anything rather than that.' Let us begin by making an agreement. 'By all means, if we can.' Well, are we not agreed that our guardians ought
