“Has joy any survival value in the operations of evolution? I suspect that it does; I suspect that the morose and fearful are doomed to quick extinction. Where there is no joy there can be no courage; and without courage all other virtues are useless.”
“Courage is the most important of all the virtues because without courage, you can't practice any other virtue consistently.”
“I believe that you can't know courage without conquering fear, and you can't really know joy without knowing sadness.”
“Courage is reckoned the greatest of all virtues; because, unless a man has that virtue, he has no security for preserving any other.”
“Without courage all other virtues lose their meaning.”
“Courage is not a virtue or value among other personal values like love or fidelity. It is the foundations that underlies and gives reality to all other virtue and personal values. (p. 13)”
