"Now I call this, dear Walter, real nobility of conduct, real moral courage in such a man as Frederick, the courage of acting out his convictions, when in so doing he was going contrary to those cherished habits and principles which were part of his very self, and made him in a degree what he was in the eyes of the world.  This was indeed moral courage, and not weak changeableness or fickleness, because it had a noble object.  To have adhered to his ordinary course in the colonel's case, when he had become convinced that he had been wronging that officer, would have been obstinacy and littleness."
