"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."
