 Imagine a person, let us call him Larry, who has a number of beliefs about arthritis. He believes that he has arthritis, that he has had it for years, that arthritis can be very painful, and that it’s better to have arthritis than pancreatic cancer, and so on. He also believes he has arthritis in his thigh. This belief, according to Burge, is (a) an arthritis-belief and (b) false. It is false because arthritis is an affliction of the joints only. But why is it an arthritis-belief—a belief about arthritis? Burge’s answer is that Larry inhabits a linguistic community made up of people who use the term “arthritis” in a certain way, and Larry would allow himself to be corrected by expert members of that community. Thus, when a doctor tells him, “No, that’s not arthritis you have. Arthritis is an affliction of the joints”. Larry would be inclined to accept this, and revise his belief accordingly.
