Date: Wed, 12 Oct 1994 04:58:55 -0700 From: James Beniger Subject: Source of Kripke Story My source for the Kripke story was a New York Times Magazine cover story on him roughly 10 years ago. Because the article was based on interviews with an impressive number of scholars from several countries, including Kripke, I tend to believe that the story is not (entirely) apocryphal. But I wasn't there, either. -- Jim Beniger ******* On Tue, 11 Oct 1994, Larry Horn wrote: > I don't know if the story is apocryphal, but I've always heard it cited > (including every time I have talked about "logical" double negation before an > audience containing philosophers) along the following lines: > > [Speaker] "...and while two negations often cancel out to an affirmative, > there is no known attestation of two affirmatives reducing to a > negative." > [Sidney Morgenbesser, in a loud sotto voce] "Yeah, yeah." > > I've come across the same anecdote a few times in print since including it in > my 1989 book "A Natural History of Negation" (p. 554) and in my 1991 CLS > paper "Duplex Negatio Affirmat...: The Economy of Double Negation" (plug, > plug) and each time the attribution was to Morgenbesser.
