It has to make sense

Here as a result of this week's work-reading is a tip to all writers and would-be writers of fantasy, spec fic, utopias, dystopias and any other genre or sub-genre that involves creating an imaginary world: the internal logic of the workings of that imaginary world has got to make sense. Causes and effects need to be consistent, because a sequence of causes and effects is what adds up to a narrative, and if your causality is not logical then your whole storyline will fall into disarray and incomprehensibility.

An obvious example: the first question a lively child reader would ask whenever anything goes wrong in the Harry Potter books is 'Why don't they just fix it with magic?' J.K. Rowling goes to great lengths in various places to anticipate this question and answer it: because they're too young, because it's against the rules, because the castle is protected, because the other person is a more powerful witch and so on.

Fantasy is a very popular genre with students of Creative Writing and this question of internal logic in created worlds is where they most often come to grief: either in failing to think fully through the implications of whatever laws and circumstances pertain to their imaginary worlds, or in failing to communicate that logic clearly enough to the reader for their stories to make sense to anyone but themselves. I often get a strong sense, reading Creative Writing theses, that the student is very clear in his or her own mind as to what the rules of this imaginary universe are, but has failed to externalise and articulate them properly in the writing process.

I wonder what the Bronte Sisters would say. One of these days I shall wake them once more from their long sleep.
