Book 3
1.101
Good is divided into four kinds. One is the possessor of virtue, whom we affirm to be individually good. Another is virtue itself and justice; these we affirm to be good. A third includes such things as food, suitable exercises and drugs. The fourth kind which we affirm to be good includes the arts of flute-playing, acting and the like. Thus there are four kinds of good: the possession of virtue; virtue itself; thirdly, food and beneficial exercises; lastly, flute-playing, acting, and the poetic art.
1.102
Whatever is is either evil or good or indifferent. We call that evil which is capable of invariably doing harm; for instance, bad judgement and folly and injustice and the like. The contraries of these things are good. But the things which can sometimes benefit and sometimes harm, such as walking and sitting and eating, or which can neither do any benefit nor harm at all, these are things indifferent, neither good nor evil. Thus all things whatever are either good, or evil, or neither good nor evil.
