Abstract
The things I wish to say here are relatively few and simple. Reflection on certain moral phenomena suggests, by way of a rather loose dialectical argument, a certain traditional theory of the nature of virtue. This is the notion that virtue consists, partly, of acting on the basis of some principle. If we do not assume in advance some narrow conception of what principles are like, this theory can provide us with a plausible account of the virtue of courage. If we take it seriously and follow its implications where they lead us we can learn something, not only about virtue, but about the nature of principle as well.
