A man will not roll in the snow for a stream of tendency by which all things fulfill the law of their being. He will not go without food in the name of something, not ourselves, that makes for righteousness. He will do things like this, or pretty nearly like this, under quite a different impulse. He will do these things when he is in love.
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.
