Abstract

Michael Dummett holds that the sense of a natural language proper name is part of its linguistic meaning. I argue that this view sits uncomfortably with Frege's observation that the sense of a natural language proper name varies from speaker to speaker. Moreover, the thesis under discussion is not supported by Frege's views on communication. Recently Richard Heck has tried to develop an argument which is intended to show that assertoric communication with sentences containing proper names is only possible if Dummett's thesis or a version of it is true. I will challenge this argument and argue that it does not support Dummett's thesis.
