I caught Jon Stewart's interview of Douglas Feith, and I am convinced that Feith does not have self awareness. He is not a sentient being. He is walking, talking evidence that consciousness is not necessary for a human to function at a fairly high level within the federal government. In fact, it may be an impediment.
I have long known that not everyone is conscious, that there are those among us who go through life, go to college, get jobs, have families, and do most of what the rest of us do except entirely without introspection and without any kind of inner life.
