 In a different vein, Alexander makes an interesting addition to Aristotle’s distinction between epistêmê and technê. In his account of wisdom in Book One of the Metaphysics, Aristotle argues that knowledge is valued for its own sake. In one place, Aristotle says that what distinguishes experience (empeiria) from technê is that the latter has a rational account, which explains what it does. Of course, the one with experience may be more effective than the inexperienced person who has only the rational account. Still, we think the craftsman wiser than the empiric because of his knowledge of the account (Metaphysics 981a 5–30). The suppressed conclusion is that wisdom is characterized by knowledge of causes quite apart from the utility of knowing the causes. Another argument shows that wisdom is not productive knowledge. Since wonder is the beginning of philosophy, satisfying that wonder is an end in itself. In fact, this kind of pursuit arose when the requirements of necessity and ease were satisfied (Metaphysics 982b 10–15). So wisdom is knowledge without practical utility, an end in itself.
