In Mind and World, John McDowell rejects a form of naturalism described by this adjective in favor of (15[1])“naturalized Platonism.” In “On What There Is,” W.V.O. Quine asks whether a possible fat man in the doorway is the same person as a man with this quality. A man who may possess this quality is at the center of the phalakros paradox, a variant of the sorites problem. (15[1]-5[1])In a 1950 paper (15[1])defining meaning as “directions for use,” P.F. (*) Strawson claims that a sentence involving this physical trait has no truth value. A paper that considers the terms “Scott” and “the author of Waverley” (-5[2])claims (10[1])that a sentence about a person with this physical property (10[1])is false. For 10 points, name this trait of Socrates and Michel Foucault, which is attributed to the “present king of France” (10[1])in Bertrand Russell’s “On Denoting.” ■END■
