Yeah I think we just have to recognize that complexity exists in the world around us. I think a lot of problems we face today are directly related to this issue. We're sold simple solutions which fall short. Our brains weren't designed to think in complicated manners and we want simplicity. But as a species we need to move beyond this. After all, one of the unique qualities of humans is being able to override our instinctual behavior (easier said than done).
But you are totally right. We must celebrate with he good in others and life or our critical observations lose all merit.
