We see everything from the narrator's point of view, so exposition about the world is limited to what impinges directly on him and the story he's telling. Considering how old the world is, we learn very little about its history, which I think is a good thing.

"Sorry," she said, "I got out as fast as I could, but I had to stay and socialize. Protocol, you know." "Explain protocol," Nell said. This was how she always talked to the Primer. "At the place we’re going, you need to watch your manners. Don’t say 'explain this' or 'explain that.'" "Would it impose on your time unduly to provide me with a concise explanation of the term protocol?" Nell said.

Coming up with lectures is a huge amount of work. I was willing to do one lecture for Gresham because I was honored to have been invited, but to create lectures for a class would probably require that I shut down everything else and concentrate on lectures for a couple of years. Then there would be many, many other skills that I'd have to learn, such as how to sit through a faculty meeting, how to deal with students, etc. It is really not in the cards for me.

Science is like the alchemists' uroburos, continually eating its own tail. The process of science doesn't work unless young scientists have the freedom to attack and tear down old dogmas, to engage in an ongoing Titanomachia. Science flourishes where art and free speech flourish.

But I'm not a small-literary-novel kind of guy, and once I'd developed the world in the first couple of hundred pages, I felt that there was potential here to go on and write an engaging story set in that world. So that's what I did. This probably ruins things both for the people who want small literary novels and for those who want action-packed epics, but anyway, it's what I wrote.
