If I ask you whether wisdom is to be desired, you admit that it is. If I ask you whether the employment of wisdom is to be desired, you also admit the fact; for you say that you will not receive wisdom if you are not allowed to employ it. Now that which is to be desired is a Good. Being wise is the employment of wisdom, just as it is of eloquence to make a speech, or of the eyes to see things. Therefore, being wise is the employment of wisdom, and the employment of wisdom is to be desired. Therefore being wise is a thing to be desired; and if it is a thing to be desired, it is a Good.
