"Spiritual fulfillment doesn't have to mean belief in a religion or disbelief in science. ... Whether one believes in an unseen, all-knowing force, or the wonder of science and the universe, or simply the beauty of the human spirit, nearly every one of feels an inner longing to feel part of something bigger than ourselves."

[Science fiction is] that class of prose narrative treating of a situation that could not arise in the world we know, but which is hypothesised on the basis of some innovation in science or technology, or pseudo-science or pseudo-technology, whether human or extra-terrestrial in origin. It is distinguished from pure fantasy by its need to achieve verisimilitude and win the 'willing suspension of disbelief' through scientific plausibility.
