Abstract

A certain familiar but “deep” joke, which might be called “The Tattletale’s Paradox,” embodies a logical confusion that figures crucially in some discussions of substantive philosophical issues. “I can’t tell you the secret,” it runs, “because if I did it wouldn’t be a secret.” It is easy enough to detect the trick involved here: to tell a secret is not to make known a piece of information that is a secret at the time that it is revealed, but rather to tell a story which was a secret but ceases to be one in the telling. The air of paradox arises insofar as we confuse the two claims.
