Great crises produce great men, and great deeds of courage.

In whatever area in life one may meet the challenges of courage, whatever may be the sacrifices he faces if he follows his conscience - the loss of his friends, his fortune, his contentment, even the esteem of his fellow men - each man must decide for himself the course he will follow. The stories of past courage can define that ingredient - they can teach, they can offer hope, they can provide inspiration. But they cannot supply courage itself. For this each man must look into his own soul.
