I came across this phrase in my research and it arrested my attention. The author was referring to the primal fear of the dark that terrified early man. It’s so cool when we come upon phrases or sentences or whole pages that make us believe there’s a writer inside us, lurking in us like a virus spreading its disease until it comes out raw and uncensored. A real writer, not just the fluff we see in grocery stores, but words that convey meaning or humor or whatever it is we’re trying to get across. That’s what we’re all after, isn’t it?
