 If this is correct, Larry’s beliefs vary between actual and counterfactual situations. Larry, however, is identical in both situations. The only difference lies in the differing natures of his linguistic communities—specifically, the differing uses of the word-form, “arthritis”. As in Putnam’s thought-experiment, the difference in meaning again stems from a difference in extension of a term, resulting in different truth-conditions, truth-makers, and the like. But in Putnam’s case, the differences stem from differences in the natural environment. In Burge’s thought experiment, these differences stem from differences in linguistic practice. As in the Putnam case, the argument can easily be extended to the contents of propositional attitudes, and Burge, unlike Putnam, explicitly endorses this extension.
