upon human beings. (Isaac Asimov 1952)

The touchstone for scientific fiction, then, is that it describes an imaginary
invention or discovery in the natural sciences. The most serious pieces of this
fiction arise from speculation about what may happen if science makes an extraordinary
discovery. The romance is an attempt to anticipate this discovery and its impact
upon society, and to foresee how mankind may adjust to the new condition.
James O. Bailey Pilgrims Through Space and Time (New York, 1947)
18. Science fiction is really sociological studies of the future, things that
the writer believes are going to happen by putting two and two together. (Ray

or in the limitless duration of time.

21. ... science fiction "is the myth-making principle of human nature today." (Lester Del Rey)
22. We talk a lot about science fiction as extrapolation, but in fact most science fiction does not extrapolate seriously. Instead it takes a willful, often whimsical, leap into a world spun out of the fantasy of the author.... (Bruce Franklin)
23. In fact, one good working definition of science fiction may be the literature which, growing with science and technology, evaluates it and relates it meaningfully to the rest of human existence. (Bruce H. Franklin)
24. Science fiction frequently tries to imagine what life would be like on a plane as far above us as we are above savagery; its setting is often of a kind that appears to us technologically miraculous. It is thus a mode of romance with a strong tendency to myth. (Northrop Frye)
25.
Science Fiction is that class of fiction which contains the currents of change
in science and society. It concerns itself with the critique, extension, revision,
and conspiracy of revolution, all directed against static scientific paradigms.
Its goal is to prompt a paradigm shift to a new view that will be more responsive
and true to nature.
Amit Goswami The Cosmic Dancers (New York, 1983)
