In moral courage the other person’s ideas, opinions, or principles are attacked, one’s own ideas, opinions, and principles being defended. There is the same fearlessness, the same attack and defense so far as the spirit of courage is concerned; but as regards its letter, these conditions have undergone a change; their physical aspect has disappeared, and, having undergone a process of transmutation, has reappeared in a new form, for moral courage is concerned not with persons as persons, but with their principles.
