“Perception is of course intimately tied to preconception. I have, as is true for each of us, a pair of cultural eyeglasses that will determine to greater or lesser degree what will be in focus, what will be a blur, what gives me a headache, and what I cannot see. I was raised a Christian—the mythology resides deep in my bones—and I know the story of Jesus nearly as well as I know my own. Until my late teens I couldn’t see some of the darker acts perpetrated in the name of Christ. I still feel a twinge each time I say, “I am not a Christian,” a slight apprehension that I may have gone too far. Sometimes I look up, a small part of my upbringing still telling me that my blasphemy will call forth a bolt of lightning from the sky.”
