Personally, I think, science fiction is a bridge between realism and imagined future. As Le Guin states, I do agree that science fiction is descriptive because its story background and topic actually comes from the present, and we can easily find the existing analog for the fiction creation in reality. Also, even for an inexistent creation, it still needs a lot of scientific knowledge background as a backup to support the logic and development of the plot. Another charm of sci-fi is because it gives another view for humans to think of themselves. How humans react under the extreme situation and how they use knowledge, courage and love to get escaped from such events, provides a condition for humans to reflect on themselves. This is why I don’t agree that reading science fiction is escapism. I think actually this is another way to face the fact and inform us a possibility that many creatures which are smarter than us or things that we cannot control exist, and in this way to encourage us to become much stronger.

Science fiction also can be considered as the story of future since compared to other kinds of fiction, its theme always relates to the advanced technology and science, space and universe, disaster and war, as well as other species, creating a kind of “unknown”. In other words, such imaginations of the future are the most attractive points in the science fiction works. However, unlike what Leguin thought, I think science fiction can work as predictive in a way, which depends on the author’s intention. In addition, thinking of this question from aspect of chronological result, some powerful science fiction works do influence the development of science.
