consequently he thinks that the primary objects of nature are to be sought for their own sake, and that virtue, which is the art of living, and can be communicated by instruction, is the most excellent of spiritual goods. This virtue, then, or art of regulating life, when it has received these primary objects of nature which existed independently of it, and prior to any instruction, seeks them all, and itself also, for its own sake; and it uses them, as it also uses itself, that from them all it may derive profit and enjoyment, greater or less, according as they are themselves greater or less; and while it takes pleasure in all of them, it despises the less that it may obtain or retain the greater when occasion demands. Now, of all goods, spiritual or bodily, there is none at all to compare with virtue. For virtue makes a good use both of itself and of all other goods in which lies man's happiness; and where it is absent, no matter how many good things a man has, they are not for his good, and consequently should not be called good things while they belong to one who makes them useless by using them badly. The life of man, then, is called happy when it enjoys virtue and these other spiritual and bodily good things without which virtue is impossible. It is called happier if it enjoys some or many other good things which are not essential to virtue; and happiest of all, if it lacks not one of the good things which pertain to the body and the soul. For life is not the same thing as virtue, since not every life, but a wisely regulated life, is virtue; and yet, while there can be life of some kind without virtue, there cannot be virtue without life. This I might apply to memory and reason, and such mental faculties; for these exist prior to instruction, and without them there cannot be any instruction, and consequently no virtue, since virtue is learned. But bodily advantages, such as swiftness of foot, beauty, or strength, are not essential to virtue, neither is virtue essential to them, and yet they are good things; and, according to our philosophers, even these advantages are desired by virtue for its own sake, and are used and enjoyed by it in a becoming manner.
