Since we live in a world of appearances, people are judged by what they seem to be. If the mind can't read the predictable features, it reacts with alarm or aversion. Faces which don’t fit in the picture are socially banned. An ugly countenance, a hideous outlook can be considered as a crime and criminals must be inexorably discarded from society. ( "Ugly mug offense" )
Jemima was not pretty, the flatness and shortness of her face made her almost plain; yet most people looked twice at her expressive countenance, at the eyes which flamed or melted at every trifle, at the rich colour which came at every expressed emotion into her usually sallow face, at the faultless teeth which made her smile like a sunbeam.
In Martin Luther's life and behavior is very courteous and friendly, and there is nothing of the stern stoic or grumpy fellow about him. He can adjust to all occasions. In social gathering he is gay, witty, ever full of joy, always has a bright and happy face, no matter how seriously his adversaries threatening him. One can see that God's strength is within him. – Petrus Mosellanus
