The first section of this article argues that the best-known definition of physical courage, stemming from Aristotle's Nicomachean Ethics, is less than fit for today's military. Having done so, a short outline is given of more scientific approaches to physical courage, drawing mainly on insights offered by psychologists, and of the problems that are inherent to these approaches. Subsequently, the article turns to a topic that is often paid lip service to in the military, yet remains somewhat hard to pin (...) down: moral courage. Although both forms of courage are intertwined, they are so in a less straightforward manner than is often thought. The way the development of physical courage in today's military is undertaken, for instance, contributes little to the development of moral courage. (shrink)
