Years ago, when I was taking a psychology class, I remember how the mood of the class became electrified toward the end of the semester when we would be studying abnormal psychology. It's all fine and good, this mood suggested, to study how the mind works and what makes people tick, but studying the diseases of the mind was getting down to brass tacs. But studying seratonin uptake inhibitors and hypochondria can only go so far in explaining the human psyche. And what does that have to do with pictures? Isn't something that steps a little outside of ordinary infinitely more interesting?
