It seems like Morrison was trying to capture the sort of 'what am I?" angst the Silver Age Negative Man, but amping it up to something beyond humanity.
Morrison in particular seems obsessed with the idea of unifying opposites, since it was a major part of Final Crisis with Superman and Ultraman merging.
