text: "That which is good makes men good. For example, that which is good in the art of music makes the musician. But chance events do not make a good man; therefore, chance events are not goods." The Peripatetics reply to this by saying that the premiss is false; that men do not in every case become good by means of that which is good; that in music there is something good, like a flute, a harp, or an organ suited to accompany singing; but that none of these instruments makes the musician. We shall then reply: "You do not understand in what sense we have used the phrase 'that which is good in music.' For we do not mean that which equips the musician, but that which makes the musician; you, however, are referring to the instruments of the art, and not to the art itself. If, however, anything in the art of music is good, that will in every case make the musician." And I should like to put this idea still more clearly. We define the good in the art of music in two ways: first, that by which the performance of the musician is assisted, and second, that by which his art is assisted. Now the musical instruments have to do with his performance, – such as flutes and organs and harps; but they do not have to do with the musician's art itself. For he is an artist even without them; he may perhaps be lacking in the ability to practise his art. But the good in man is not in the same way twofold; for the good of man and the good of life are the same.
