I was reading Choosing The Common Good over the weekend, and I think I understand another reason why I'm very wary of the Catholic bishops' advocacy of virtue ethics. It's because theirs is actually an amalgam of virtue description and rule prescription. Or to put it another way, it's a mix of life as a moral art and life as a moral science. And the two approaches don't mix very well.

The Catholic stipulations against sex outside of marriage provide a good case in point. To have a blanket ban can only come from a rule approach. It's wrong, period. But with a virtue approach, pre-marital sexual exploration, say, may be a great good, if not without risks - though virtue ethics requires the taking of risks to gain the practical intelligence it so values. Hence too the desirability of sex education. Also, a virtue approach doesn't see any strict distinction between sex and love, one flowing from the other in the good life. There are some sexual relationships its unwise, even bad, to pursue. But marriage as a inviolable demarcation comes to look rather arbitrary - and unjust in the case of lovers for whom marriage is not an option, as, in the eyes of the church, is the case for lesbians and gays.
