The soul is divided into two parts, of which one is in itself possessed of reason, while the other is not rational in itselfbut capable of obeying reason. To these parts in our view belong those virtues in accordance with which a man is pronounced to be good in some way. But in which of thesetwo parts the end of man rather resides, those who define the parts of the soul in accordance with our view will have no doubt as to how they should decide. The worse always exists as a means to the better, and this is manifest alike in the products of art and in those of nature; but the rational part of the soul is better than the irrational. And the rational part is subdivided into two, according to our usual scheme of division; for reason is of two kinds, practical and theoretic, so that obviously the rational part of the soul must also be subdivided accordingly. A corresponding classification we shall also pronounce to hold among its activities: the activities of the part of the soul that is by nature superior must be preferable for those persons who are capable of attaining either all the soul’s activities or twoi.e. the two lower ones, the three being the activities of the theoretic reason, of the practical reason, and of the passions that although irrational are amenable to reason. out of the three; since that thing is always most desirable for each person which is the highest to which it is possible for him to attain. Also life as a whole is divided into business and leisure, and war and peace, and our actions are aimed some of them at things necessary and useful, others at things noble. In these matters the same principle of preference that applies to the parts of the soul must apply also to the activities of those parts: war must be for the sake of peace, business for the sake of leisure, things necessary and useful for the purpose of things noble. The statesman therefore must legislate with all these considerations in view, both in respect of the parts of the soul and of their activities, and aiming more particularly at the greater goods and the ends. And the same principle applies in regard to modes of life and choices of conduct: a man should be capable of engaging in business and war,
