For instance, in his blog post “A formalist manifesto” he declares that “you’re bound by a rule if, and only if, you agree to it. We don’t have rules that are made by the gods somewhere. What we have is actually not rules at all, but agreements.” And he follows this to a logical endpoint, saying that “if you’re a wild man and you agree to nothing—not even that you won’t just kill people randomly on the street—this is fine. Go and live in the jungle, or something. Don’t expect anyone to let you walk around on their street, any more than they would tolerate, say, a polar bear.”
