What is a great man who has made his mark upon history? Every time, if we think far enough, he is a man who has looked through the confusion of the moment and has seen the moral issue involved; he is a man who has refused to have his sense of justice distorted; he has listened to his conscience until conscience becomes a trumpet call to like-minded men, so that they gather about him, and together, with mutual purpose and mutual aid, they make a new period in history.
