" Then, and again and always,” went on Syme like a man talking to himself, “that has been for me the mystery of Sunday, and it is also the mystery of the world. When I see the horrible back, I am sure the noble face is but a mask. When I see the face but for an instant, I know the back is only a jest. Bad is so bad, that we cannot but think good an accident; good is so good, that we feel certain that evil could be explained. "
