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 MayCourage is the capacity to meet the anxiety which arises as one achieves freedom. It is the willingness to differentiate, to move from the protecting realms of parental dependence to new levels of freedom and integration.
