But when he thinks that he is the sufferer of the wrong, then he boils and chafes, and is on the side of what he believes to be justice; and because he suffers hunger or cold or other pain he is only the more determined to persevere and conquer. His noble spirit will not be quelled until he either slays or is slain; or until he hears the voice of the shepherd, that is, reason, bidding his dog bark no more. The illustration is perfect, he replied; and in our State, as we were saying, the auxiliaries were to be dogs, and to hear the voice of the rulers, who are their shepherds. I perceive, I said, that you quite understand me; there is, however, a further point which I wish you to consider. What point? You remember that passion or spirit appeared at first sight to be a kind of desire, but now we should say quite the contrary; for in the conflict of the soul spirit is arrayed on the side of the rational principle. Most assuredly. But a further question arises: Is passion different from reason also, or only a kind of reason; in which latter case, instead of three principles in the soul, there will only be two, the rational and the concupiscent; or rather, as the State was composed of three classes, traders, auxiliaries, counsellors, so may there not be in the individual soul a third element which is passion or spirit, and when not corrupted by bad education is the natural auxiliary of reason Yes, he said, there must be a third. Yes, I replied, if passion, which has already been shown to be different from desire, turn out also to be different from reason. But that is easily proved:--We may observe even in young children that they are full of spirit almost as soon as they are born, whereas some of them never seem to attain to the use of reason, and most of them late enough. Excellent, I said, and you may see passion equally in brute animals, which is a further proof of the truth of what you are saying. And we may once more appeal to the words of Homer, which have been already quoted by us, He smote his breast, and thus rebuked his soul, for in this verse Homer has clearly supposed the power which reasons about the better and worse to be different from the unreasoning anger which is rebuked by it. Very true, he said. And so, after much tossing, we have reached land, and are fairly agreed that the same principles which exist in the State exist also in the individual, and that they are three in number. Exactly. Must we not then infer that the individual is wise in the same way, and in virtue of the same quality which makes the State wise? Certainly. Also that the same quality which constitutes courage in the State constitutes courage in the individual, and that both the State and the individual bear the same relation to all the other virtues? Assuredly. And the individual will be acknowledged by us to be just in the same way in which the State is just? That follows, of course.
