The Stanford Encyclopedia of Philosophy may be the most interesting website on the internet. Not because of the content—which includes fascinating entries on everything from ambiguity to zombies—but because of the site itself. 1 Its creators have solved one of the internet’s fundamental problems: How to provide authoritative, rigorously accurate knowledge, at no cost to readers. It’s something the encyclopedia, or SEP, has managed to do for two decades. The internet is an information landfill. Somewhere in it—buried under piles of opinion, speculation, and misinformation—is virtually all of human knowledge. The story of the SEP shows that it is possible to create a less trashy internet. But sorting through the trash is difficult work. Even when you have something you think is valuable, it often turns out to be a cheap knock-off. The story of how the SEP is run, and how it came to be, shows that it is possible to create a less trashy internet—or at least a less trashy corner of it. A place where actual knowledge is sorted into a neat, separate pile instead of being thrown into the landfill. Where the world can go to learn everything that we know to be true. Something that would make humans a lot smarter than the internet we have today.
