According to Aristotle, excellence of character and intelligence cannot be separated. Here Aristotle expresses a view characteristically at odds with that dominant in the modern world. The modern view is expressed at one level in such banalities as ‘Be good, sweet maid, and let who will be clever’ and at another in such profundities as Kant’s distinction between the good will, the possession of which alone is both necessary and sufficient for moral worth, and what he took to be a quite distinct natural gift, that of knowing how to apply general rules to particular cases, a gift the lack of which is called stupidity. So for Kant one can be both good and stupid; but for Aristotle stupidity of a certain kind precludes goodness.
