[M]odern politics cannot be a matter of genuine moral consensus. And it is not. Modem politics is civil war carried on by other means. ...The truth o… - Alasdair MacIntyre

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.

[M]odern society is indeed often, at least in surface appearance, nothing but a collection of strangers, each pursuing his or her own interests under minimal constraints. We still of course, even in modern society, find it difficult to think of families, colleges and other genuine communities in this way; but even our thinking about those is now invaded to an increasing degree by individualist conceptions, especially in the law courts.

Consider what kind of authority [can be ascribed to] any principle which it open to us to choose to regard as authoritative or not. I may choose for example to observe a regimen of asceticism and fasting … for reasons of health … What authority such principles possess derives from the reasons for my choice. Insofar as they are good reasons, the principles have corresponding authority; insofar as they are not, the principles are to that same extent deprived of authority. It would follow that a principle for the choice of which no reasons could be given would be a principle devoid of authority. I might indeed adopt such a principle from whim or caprice or from some arbitrary purpose … but if I then chose to abandon the principle whenever it suited me, I would be entirely free to do so.
