It's akin to style, what I'm talking about, but it isn't style alone. It is the writer's particular and unmistakable signature on everything he writes. It is his world and no other. This is one of the things that distinguishes one writer from another. Not talent. There's plenty of that around. But a writer who has some special way of looking at things and who gives artistic expression to that way of looking: that writer may be around for a time.
