Book 7
1.103
For as the property of hot is to warm, not to cool, so the property of good is to benefit, not to injure; but wealth and health do no more benefit than injury, therefore neither wealth nor health is good. Further, they say that that is not good of which both good and bad use can be made; but of wealth and health both good and bad use can be made; therefore wealth and health are not goods. On the other hand, Posidonius maintains that these things too are among goods. Hecato in the ninth book of his treatise On Goods, and Chrysippus in his work On Pleasure, deny that pleasure is a good either; for some pleasures are disgraceful, and nothing disgraceful is good.
1.104
To benefit is to set in motion or sustain in accordance with virtue; whereas to harm is to set in motion or sustain in accordance with vice.
