Courage is one of these systems. It is not merely the absence of fear that constitutes courage, though we interchange "fearless" with "courageous." Frequently it is the conquest of fear by the man himself that leads him to the highest courage. There is a type of courage based on the lack of imagination, the inability to see ahead the disaster that lurks around every corner. There is another type of courage based on the philosophy that to lose control of oneself is the greatest disaster. There are the nobly proud, whose conception of "ought," of "noblesse oblige," makes them the real aristocrats of the race.
