A few years back, there was meme going around the online writing community about what the differences between fantasy and science fiction. Most of the answers were intended to be humorous, because, at first glance, fantasy and science fiction are easy to tell apart. Common answers included “it’s fantasy when you pay in coin, and science fiction when you pay in credits;” “it’s fantast when you ride horses, and it’s science fiction when you ride a space ship;” and other simple, fairly obvious explanations that basically boiled down to it’s fantasy when the speculative element is magical, and it’s science fiction when the speculative element is scientific. The meme resurfaces each year, and I was recently reminded of it three separate times during interactions on social media. During one of those interactions, which was a chat on BlueSky where writers were asked to answer a series of questions as part of a chat event, I gave an answer that fit into the character limit, which got a decent reaction, but which I feel needs to be explained in a longer-format piece like this one: Science fiction speculates based on the conscious, rational mind, whereas fantasy is derived from the subconscious or irrational.
To me, science fiction, for the most part, evolves from a rational premise taken to an extreme. What if some new piece of technology existed? How would we deal with that, both as individuals and as a species? AI, space travel, and even time travel would be examples of this type of fiction. What if a certain social construct or system in the real world was either amplified to the extreme or allowed to continue unfettered on its present course? Dystopian sci-fi, social-critical science fiction, and solar-punk would fit under that rubric. In summary, most of what is considered science fiction derives from a real world situation taken to a logical extreme.
On the other hand, fantasy, generally comes from a different place, and since it is not based in reason, it will take a bit longer to explain. Let’s start with the father of modern fantasy, JRR Tolkien. In his essay “On Fairy Stories,” Tolkien writes the following:
“Now “Faërian Drama”—those plays which according to abundant records the elves have often presented to men—can produce Fantasy with a realism and immediacy beyond the compass of any human mechanism. As a result their usual effect (upon a man) is to go beyond Secondary Belief. If you are present at a Faërian drama you yourself are, or think that you are, bodily inside its Secondary World. The experience may be very similar to Dreaming and has (it would seem) sometimes (by men) been confounded with it. But in Faërian drama you are in a dream that some other mind is weaving, and the knowledge of that alarming fact may slip from your grasp.” [Emphasis mine]
This part of the essay is a part of a larger discussion, of great interest to Tolkien, about the magic–the spell–of words and their effect on the reader, but for our purposes, the point is that, in what some scholars have called his most successful attempt to define the fantasy genre (fantasy and fairy stories are synonyms for our purposes), he uses the metaphor of a dream.
A dream is one the most common manifestations of the subconscious. We could examine the implications of the dream being someone else’s rather than our own at a different time, because that is another essay entirely, but the important thing is that the realm of fairy, and by extension, secondary world fantasy, is associated not with reality or with something connected to reality like time or space, but rather with something from the subconscious, outside the realm of rational experience.
This, by the way, does not preclude the fantasy rules from having it’s own rules or logic. Tolkien discusses the need to keep the secondary world consistently logical with itself elsewhere in the same essay, but the rules there, are different than rules here, and what happens when you are under the glamour of the story, is outside of the logical, rational realm.
While Tolkien wrote about secondary world fantasy, which makes sense given that the vast majority of his fiction takes place in a secondary world, the root of all fantasy derives from the subconscious, even those stories which take place in our world.
I recently attended an online discussion with Alan Moore and Susanna Clarke, two of the greatest contemporary fantasy writers. Clarke and Moore both write fantasy set in the “real” world, yet when they talk about fantasy, it is tinged with the same types of allusions to the subconscious, the irrational, and the extra-rational.
Moore said, “there is a thin membrane between fiction and reality. It must be permeable.”
Clarke said fantasy “becomes a repository for all the non-human things which we are ignoring.”
Both of these statements reflect a psychoanalytic lens for looking at fantasy, and Clarke’s repeated references to Jung during the talk establish the connection between the subconscious and fantasy to an even greater degree.
If we look at where the fantasy element is found in fantasy stories which take place in the so-called-real-world, they often echo these archetypes as well. The fantastical or magical element comes from underground (as, for example, in Neil Gaiman’s Neverwhere), on the edge of town, from a foreign land, or from some distant past (as in Clarke’s Jonathan Strange and Mr. Norrell). Irrational states, like madness or religious fervor are often conducive to magic as well. Each of these metaphors relies on a common metaphor for the subconscious, a liminal state reminiscent of a dream.
Thus, fantasy, regardless of setting, bubbles up from the subconscious whereas science fiction is the logical extension of the rational.
