On Science Fiction NCERT Book PDF Overview
On Science Fiction is a non-fiction essay by Isaac Asimov in the Kaleidoscope textbook. Asimov explains that science fiction is not just fiction with machines or planets. It is fiction where the background has changed because science has changed human life.
The chapter is best read as a genre lesson. Asimov first compares old mythic thinking with the scientific universe. He then explains why a science fiction story must keep its own rules fair, especially when it works like a mystery.
| Part of chapter | What to notice | Answer cue |
|---|---|---|
| Prescientific universe | People explained events through gods, spirits and myths. | Use for fantasy background. |
| Scientific universe | Science changes what people can imagine as possible. | Use for science fiction validity. |
| Genre distinction | Background decides the genre more than surface content. | Use for sports, western, jungle and science fiction comparison. |
| Fair mystery | The writer must share enough clues with the student. | Use for mystery-writing rules. |
Science Fiction Idea Path in On Science Fiction
Asimov moves from a prescientific world to a scientific one. In older stories, strange events could be explained by magic or divine power. In science fiction, the strange event must feel possible inside a changed scientific background.
For board answers, keep the sequence simple. Start with myth and fantasy, then explain the scientific universe, and finally connect it to fair science fiction mystery. The key point is that science fiction depends on believable possibility.

Fantasy and Science Fiction in the Chapter
Fantasy and science fiction may both show unusual events. The difference lies in the rules of the imagined world. Fantasy can use magic as its background. Science fiction uses scientific change, invention or discovery as its background.
- Fantasy: the impossible may be accepted through myth, magic or miracle.
- Science fiction: the unusual event must feel possible through scientific logic.
- Mystery angle: the solution should not cheat the student by hiding essential clues.
Use this section for questions on genre distinction and fair mystery writing. Asimov's examples help students avoid vague answers like "science fiction is about science."
