It is hard to define science fiction since there are multiple explanations of science. Science in science fiction can be read both as based on scientific knowledge and storytelling in a logical system. With these extensions, I agree with definition in Le Guin’s introduction, science fiction is a description of the real world, in the present or in the future.

What is the nature of science fiction? I consider it a description of details in the real-world under highly developed technology. These details are in the form of conflicts, it can be gradually changing, or strong comparison. Those conflicts exist before technology takes over the world, at least their seeds are buried beneath. Like the city in Folding Beijing by author Jingfang Hao, which contains three spaces assigned to different time zones. Each zones have specific occupies. This city structure is a metaphor for modern classes that exist for a really long time.

There are still some problems that not coming up but their footprints can be predicted and tracked. Science fiction builds future world logically by analysis of presenting technology and society issues. Those conflicts may not inevitably occur, but there are still probabilities in some ways. The war of the worlds, this fiction tells a story about how humans survive under Martians’ attack. Those Martians kill tons of humans while finally dead under a virus on Earth. Nowadays, human seems to be the domination of the planet, seeking lives in-universe, while is under threatened by an unknown virus, like Ebola virus and recently coronavirus. This is the reason why we read science fiction: it reveals the truth.

In the future, science fiction may get rid of the limit form of literature. But when we look into history, Bible, Grimm’s Fairy Tales, Greek Tragedy, Roman mythology, and folk legend reveal the truth by storytelling. With developing technology, science fiction’s definition will be renewed and its meaning will be brought up and accepted widely.
