I have confronted theoretical positions whose protagonists claim that what I take to be historically produced characteristics of what is specifically modern are in fact the timelessly necessary characteristics of all and any moral judgment, of all and any selfhood.

According to Aristotle then 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.

The tradition of the virtues is at variance with central features of the modern economic order and more especially its individualism, its acquisitiveness and its elevation of the values of the market to a central social place. It now becomes clear that it also involves a rejection of the modern political order. ...Modern systematic politics, whether liberal, conservative, radical or socialist, simply has to be rejected from a standpoint that owes genuine allegiance to the tradition of the virtues; for modern politics itself expresses in its institutional forms a systematic rejection of that tradition.
