text: We of the Stoic school believe that the Good is corporeal, because the Good is active, and whatever is active is corporeal. That which is good, is helpful. But, in order to be helpful, it must be active; so, if it is active, it is corporeal. They (the Stoics) declare that wisdom is a Good; it therefore follows that one must also call wisdom corporeal. But they do not think that being wise can be rated on the same basis. For it is incorporeal and accessory to something else, in other words, wisdom; hence it is in no respect active or helpful.
