I once asked a friend of mine who reads a great deal of Science Fiction and Fantasy what he saw as the essential difference between the two genres. He thought for a moment and said that Science Fiction “could happen” while Fantasy “could not.”
I think I know what he meant. In Science Fiction, the writer is cognizant of the physical laws operative within the story. If an SF writer were to describe space travel, Newton’s Laws of motion and gravity would be obeyed. Even here one enters a grey area: some writers would insist on using the speed of light as a fixed limitation while others would imagine a way around it.
In my high school years, I grew up on this genre and my love of science, in large measure, grew out of that reading. Several friends had urged me to read The Hobbit and The Lord of the Rings, but I resisted for a long time. When I did read it, it was as if a new world had opened up for me. It recaptured for me what I had experienced as a child on first reading The Chronicles of Narnia. There was a sense of nobility, beauty, and “rightness” about those imagined worlds that I had missed in my Science Fiction reading, which instead, seemed sterile in comparison.
The longer I thought about it, it came to me that I was encountering an unspoken presupposition that was embedded in most SF literature, that of a materialistic universe where all that mattered was atoms and molecules; chemistry and physics. In addition, I found that the more modern SF also grew more cynical, growing increasingly hostile to the very things that I loved in Fantasy. As a consequence, I read very few modern SF stories (although I do try them once in a while) and spend much more time reading Fantasy.
So how has this impacted my writing? I think, in The Halcyon Cycle, I write Science Fiction that reads like Fantasy. I spend a good deal of time thinking about the physics and chemistry behind my imagined world (I think some of my readers would argue too much, in fact), but I also have many of the elements of a Fantasy story (swords, nobility, right and wrong which transcends worlds and physical laws for example).
