"Courage" Lord Moran shrewdly observed, "is a moral quality; it is not a gift of nature like an aptitude for games. It is a cold choice between two alternatives, the fixed resolve not to quit; an act of renunciation which must be made not once but many times, by the power of the will. Courage is will power." James 1:2-4

Lord Moran "The Anatomy of Courage"
p. 129 (Masters of the Air) "Courage is will power, whereof no man has an unlimited stock; and when in war it is used up, he is finished. A man's courage is his capital and he is always spending."
