"Substance" is not enough: "accident" is also required, as the scholastics say. A bad manner spoils everything, even reason and justice; a good one supplies everything, gilds a No, sweetens truth, and adds a touch of beauty to old age itself. The how plays a large part in affairs, a good manner steals into the affections. Fine behaviour is a joy in life, and a pleasant expression helps out of a difficulty in a remarkable way.
