The Sin of Worldbuilding
Forgive me, Warren, but I must disagree.
Every moment of a science fiction story must represent the triumph of writing over worldbuilding.
Worldbuilding is dull. Worldbuilding literalises the urge to invent. Worldbuilding gives an unnecessary permission for acts of writing (indeed, for acts of reading). Worldbuilding numbs the reader’s ability to fulfil their part of the bargain, because it believes that it has to do everything around here if anything is going to get done.
Above all, worldbuilding is not technically necessary. It is the great clomping foot of nerdism. It is the attempt to exhaustively survey a place that isn’t there. A good writer would never try to do that, even with a place that is there. It isn’t possible, & if it was the results wouldn’t be readable: they would constitute not a book but the biggest library ever built, a hallowed place of dedication & lifelong study. This gives us a clue to the psychological type of the worldbuilder & the worldbuilder’s victim, & makes us very afraid.
See, what he misses here is that Worldbuilding is its own form of art, and very much its own kind of business. Worldbuilding is what I do pretty much every gig for Institute for the Future, for Global Business Network, for Monitor Institute, and for essentially every corporate, government, or non-profit client I've worked with over the last decade. That great clomping foot of nerdism is what the clients want to see, because they can then use that as a backdrop for their own stories about their organizations.
The art of Worldbuilding comes from knowing what to omit, from knowing what needs to be surveyed and what can be tacked up as a Potemkin Future. It becomes an intensely detailed game, figuring out what the readers want to know, covering what they need to know, teasing them with the implications of a fuller vision, and creating an effective illusion of paradigmatic completeness.
Harrison has it wrong: it's not the biggest library ever built, it's a painting of a library that seems to go on and on, with some prop books on a table in the foreground. Make sure those prop books are interesting enough, and the reader will never try to explore the rest of the library.
