By challenging anthropocentricism and temporal provincialism, science fiction throws open the whole of civilization and its premises to constructive criticism.

The most visceral science fiction always takes place in the past and focuses on the humdrum.

That’s all science fiction was ever about. Hating the way things are, wanting to make things different.

I am constantly amazed by how much stranger science is than science fiction.

Science fiction isn’t just thinking about the world out there. It’s also thinking about how that world might be—a particularly important exercise for those who are oppressed, because if they’re going to change the world we live in, they—and all of us—have to be able to think about a world that works differently.

We hope it will not be long before we may have other works of Science-Fiction, as we believe such works likely to fulfil a good purpose, and create an interest, where, unhappily, science alone might fail.

The purpose of a storyteller is not to tell you how to think, but to give you questions to think upon.

[Science fiction is] the attempt to deal rationally with alternate possibilities in a manner which will be entertaining.

A better generic term would be ‘future fairy tales’. And even this is objectionable, since many science fiction stories take place in the present or the past, far and near.

To write good sci-fi today you must push further and harder, reach deeper into your own mind until you break through into the strange and terrible country wherein live your own dreams.

“Science fiction deals with improbable possibilities, fantasy with plausible impossibilities.”

Once it gets off the ground into space, all science fiction is fantasy.
