A lot of the stuff Kafka said he thought was hilariously funny.

We thought we were running away from the grownups, and now we are the grownups.

Fiction is not necessarily about what you know, it's about how you feel. That is the truth about fiction, and the other truth is that all science is a tool, and we use our tools not to actualise what we know, but to implement how we feel.

If you DJ reality, that is, if you make a mash-up of actual reality, you're going to end up with something that inevitably people will say, "This is feminist." Because you cannot avoid that.

Writers are much better behaved nowadays, for a couple of reasons. Once upon a time nobody was thinking of a career, unless you lived in New York, so there wasn't as much pressure to present a respectable exterior. And secondly, there was no social media. So if you were found face down on the floor - people did do that quite a bit; usually men, but not always - or fell through plate glass windows or got into scrapes, it became a rumor, and rumors are hard to pin down.

I define science fiction as fiction in which things happen that are not possible today - that depend, for instance, on advanced space travel, time travel, the discovery of green monsters on other planets or galaxies, or that contain various technologies we have not yet developed.

As soon as you have a language that has a past tense and a future tense you're going to say, 'Where did we come from, what happens next?' The ability to remember the past helps us plan the future.
