We humans often do not understand each other very well. I heard a retired industrial worker recently lament, "My boss never understood me or any of his employees, and I never understood anything he did." I heard two radio news commentators recently discussing the tragedies of politics, diplomacy, and warfare continuing to unfold in the Middle East due to a lack of understanding.
It isn't surprising. People are complicated, fickle, and unpredictable. But because we live and work together, we must try to deal with it.
Individual people constitute great bundles of intellectual, emotional, behavioral, spiritual, and physical phenomena, internal contradictions, and anomalies. Social scientists tell us that societies exhibit similar complexities. It is all very complicated and difficult to understand.
