 (Discussions linking knowledge of other minds and the past provide a rich vein of philosophical discussion; see, for example, Dummett 1969, Wright 1980, and McDowell 1998.) It may be thought that there could be a way of knowing another’s mind—say by telepathy—and that it is simply a contingent fact that this is not a way that is open to human beings. Telepathy would allow one to know another’s thoughts and feelings by coming to share them. The problem, however, is that if I have your experiences, then those experiences are mine and not yours. As Ayer writes: “In this respect telepathy is no better than the telephone” (1953 [1954: 196]; cf. Austin 1946 and Wisdom 1940).
