Do it for yourself. The universe will be around to collect its cut later.

Fiction is simply dreams written out. Science fiction consists of the hopes and dreams and fears (for some dreams are nightmares) of a technically based society.

Reality is frequently inaccurate.

Science fiction is the only literature capable of exploring the macrohistory of our species, and of placing our history, and even our daily lives, in a cosmic context.

Science fiction is the major non-realistic mode of imaginative creation of our epoch. It is the principal cultural way we locate ourselves imaginatively in time and space.

Science fiction is, after all, the art of extrapolation.

Anything you dream is fiction, and anything you accomplish is science, the whole history of mankind is nothing but science fiction.

It’s a point that science fiction makes constantly: the future belongs to us — whatever it is. We make it, our actions shape tomorrow. We have the brains and guts to build paradise (or at least try). Tragedy is when we fail, and the greatest crime of all is when we fail even to try.
Thus science fiction stands as a bridge between science and art, between the engineers of technology and the poets of humanity.

A science fiction story is one which presupposes a technology, or an effect of technology, or a disturbance in the natural order, such as humanity, up to the time of writing, has not in actual fact experienced.

Science fiction is the arena of the not-yet, and every science fiction story has this element of not-yet-ness… usually a bit of technology or a scientific discovery that we don’t know about in the real world of the present but that might be a possibility in the future.

Science-fiction balances you on the cliff. Fantasy shoves you off.
