It is hard to swear when sex is not dirty and blasphemy does not exist.

Readers, after all, are making the world with you. You give them the materials, but it's the readers who build that world in their own minds.

What is love of one's country; is it hate of one's uncountry? Then it's not a good thing. Is it simply self-love? That's a good thing, but one musn't make a virtue of it, or a profession...Insofar as I love life, I love [my country], but that sort of love does not have a boundary-line of hate.

Safety lies in catering to the in-group. We are not all brave. All I would ask of writers who find it hard to question the universal validity of their personal opinions and affiliations is that they consider this: Every group we belong to - by gender, sex, race, religion, age - is an in-group, surrounded by an immense out-group, living next door and all over the world, who will be alive as far into the future as humanity has a future. That out-group is called other people. It is for them that we write.

Sci-fi uses the images that sf - starting with H.G. Wells - made familiar: space travel, aliens, galactic wars and federations, time machines, et cetera, taking them literally, not caring if they are possible or even plausible. It has no interest in or relation to real science or technology. It's fantasy in space suits. Spectacle. Wizards with lasers. Kids with ray guns. I've written both, but I have to say I respect science fiction enough that I wince when people call it sci-fi.
