I once used the metaphor that you can’t see the back of your own head without a mirror to describe the importance of feedback, but I was wrong. One mirror is not enough. It takes two.
So too, is the peculiar arrangement that allows us to see depth, two eyes pointing forward, binocular vision, two different points of view, two perspectives which the brain compares and combines into an image of a world with three dimensions. Its the same with hearing. It is the difference between the stories told by the two eyes or ears that gives the richness. Dogs, by the way, do the same thing with their noses.
Where am I going with this? Not far. Its a sort of cautionary tale of the danger and limitation of isolating ourselves in information and opinion and belief bubbles where only one story is told, only one point of view. That may be comfortable and reassuring, but it is flat, without depth. The conversations that enrich need differences.
Ok, that’s it. I could probably spin that out with sufficient inspiration, but that seems a bit lacking today. So, there it is, off the top of my head.
