The "random acts of blindness" to which I refer attests to a long list of observable phenomena which I have trouble seeing. I don't mean to suggest that my eyes are incapable of vision. I see things I sometimes fail to see. In the scheme of things these are not with any degree of consequence. Wether I see these things or not matters little. My blindness has no effect beyond my puzzled mind. No one's life hangs in the balance. The earth will not disintegrate because of my failure to perceive the logic of something that seems to defy common sense. Nevertheless, there remains a host of things I just don't see.
