I’m going to try something different now to help try to post more often. Namely, not worry so much about the result and just try to exorcise the ideas as they come. Without further ado…
I was thinking about how I typically enjoy science-fiction novels more than fantasy and I wondered why this was. Then it occurred to me that fantasy is typically regressive and nostalgic. It represents a longing for the child’s world and an escape from reality. Harry Potter is a good example of this, as is the Lord of the Rings. I would even say that Star Wars is a fantasy film, rather than a science-fiction film. The technology in Star Wars is rarely focused on or explained (compared to Star Trek, which does attempt to explain), instead the story is consumed with the magical metaphysics of the Force. So, Star Wars is a space fantasy. Complete with wizards (Obi Wan) and dark lords.
Fantasy is about a small, simple, magical world. This is the world of the child, but also the world of the past. Looking back things become simple and romanticized. The concept of the Golden Age is as old as we are.
Fantasy worlds operate as cartoonish backdrops for personal dramas and interpersonal narratives. There is often little explanation of how things work or any real consciousness of the larger objective reality. There is a narrowness of perspective that often dictates a flatness and reliance on cliche that relegates fantasy narratives to the ghetto of genre fiction. Fantasy narratives like The Lord of the Rings occasionally break out and do something impressive, but only by taking on greater reality and connection to the real world. Much of LoTR is inspired directly by Anglo-Saxon and Germanic history and much of its resonance is due to its connection to this world, also referred to as “Middle Earth” in Norse myth.
Science-fiction is about the future from the perspective of the present. It is not really about the future itself. This is why science-fiction often ages badly. Science-fiction seeks to enlarge the compass of the known. It is speculative. And, in speculating it is often laughably wrong. But, it also points the way and suggests possibilities for how the present could develop along its current course. Science-fiction is prophetic where fantasy is sentimental. Science-fiction, since it encourages a more broad perspective, is more creative and interesting. Fantasy is referential and narrow and as soon as it becomes unmoored from cliche it ceases to be fantasy and becomes science-fiction or speculative fiction.
Of course, many science-fiction narratives are so narrow as to resemble fantasy. Just replace the tableau of swords, elves, and magic with lasers, aliens, and advanced inexplicable science and you have the same uninteresting garbage.
