The companion book presents these two as enemies, working out their differences. The one on the left could still grab his sword and spring up, the one on the right is deadly serious from his posture and the way he is presenting his sword.
To live in this world, in one form or another these postures often need to be figuratively assumed. Making peace doesn't need to equal submission; refusing to admit to alternate viewpoints equals sheer chaos. I know people who can't be wrong and can't be approached. How can they ever know any kind of peace or joy or the pleasure of teamwork, friendship, or marriage?
"Progress is impossible without change, and those who cannot change their minds cannot change anything." ~ George Bernard Shaw 1856-1950
