In Mind and World, John McDowell rejects a form of naturalism described by this adjective in favor of “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, (15[1])a variant of the sorites problem. In a 1950 paper defining meaning as “directions for (15[1])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” (10[1])claims that a sentence about a person with this physical property is false. For 10 points, name this trait of Socrates and Michel Foucault, which is attributed to the “present king of France” in Bertrand Russell’s “On Denoting.” ■END■
