Talk about luck! On the role of knowledge in communication
摘要
The correct account of communication, it is widely held, must accommodate the kind of case presented by Brian Loar (Philos Stud 30(6): 353-377, 1976) in which subjects misunderstand each other despite referring to the same entity. Epistemic Russellianism (ER) has emerged as a strong new candidate to accomplish this task. Claiming that the significance of Loar’s puzzle is due to an element of luck, as in Gettier’s (Analysis 23(6): 121-123, 1963) cases, ER concludes that communication requires knowledge of co-reference, and not a match in Fregean sense or mode of presentation. My aim is twofold. Firstly, I deploy some defensive moves against recent ER-based attacks on a Fregean approach to communication. Secondly, as an offensive manoeuvre, I argue that ER’s knowledge-based view faces the problem posed by cases of lucky communication. These cases show that drawing a knowledge-of-co-reference condition on communication is unwarranted. The upshot of my discussion is that the Fregean approach is still the stronger contender of the two.
