I was thinking of my father yesterday...
When he was a child he listened to the radio, one of his favorite shows was "The Shadow." The opening of each broadcast started with a question and an answer: "WHO KNOWS WHAT EVIL LURKS IN THE HEARTS OF MEN? THE SHADOW KNOWS!" I believe it was Orson Welles, who intoned those thrilling words in deep resonant tones. My father loved to do his "Orson Welles," by speaking these prophetic words himself.
Now, according to C.G. Jung, all of us have the "shadow," as part of our psychological makeup...so really, we all know what evil lurks in the hearts of men (and women) because that "evil" resides in us too. Maybe the word "evil," is a little harsh, maybe not, look at the world, what do you think? But at least we know there's light and dark (see Obi Wan Kenobi!). So when something really goes bad, when people seriously take the wrong path (think White House Cabal!), there's always a little twinge of recognition, isn't there?
We all need to be honest with ourselves, and try to keep each other honest too. We must expose the darkness to the light, and so, transform it! HA, HA, HA!
