The word courage comes from the same stem as the French word Coeur, meaning "heart." Thus just as one's heart, by pumping blood to one's arms, legs, and brain enables all the other physical organs to function, so courage makes possible all the psychological virtues. Without courage other values wither away into mere facsimiles of virtue.
Rollo MayJoy, rather than happiness, is the goal of life, for joy is the emotion which accompanies our fulfilling our natures as human beings. It is based on the experience of one's identity as a being of worth and dignity.
