But our object is unmistakeably virtue, and virtue is of four kinds.

'Yes; and we said that mind is the chief and ruler of the three other kinds of virtue and of all else.' True, Cleinias; and now, having already declared the object which is present to the mind of the 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.
