Do we have a responsibility as writers to consider how our characters, ideas and the way we express them could impact our readers? Should we have an idea of what our characters represent? Should we be aware of the innate symbolism in the elements we use? If we cannot justify why we chose to write something a particular way, no matter what it might be, no matter how small a part it plays in the overall scheme of our story, have we really written anything of value to anyone? Is this a philosophical matter or intrinsic to the craft of writing?
