I've been thinking about this for years, and I am not sure. All the metaphors for creativity listed above are very astute but ascribing all creativity as a channeling makes me worry most over responsibility. Ideas are powerful and I think we must at some point concern ourselves with the kind of actions they might produce. The writer is creating an artifact to be viewed by anyone, and though we cannot anticipate every moral response, it doesn't mean we should throw all caution to the wind and write whatever comes to mind. The imagination is subject to the darker aspects of the human experience as well.
