Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Content-Disposition: inline From: And Rosta X-Yahoo-Message-Num: 11579 John: #In English, "today" and "tomorrow" are normally token-reflexive, then, #but in this sentence are used in the senses "a day" and "the successor #of that day". Jorge: #The only way to solve it is to make explicit the universal #quantification that "if" hides in English. You can quantify #over all possible worlds (ro mu'ei), then, since there will #always be one in which today is Monday, that will be enough to #make the second sentence always false. (You have to limit #possible worlds to those in which Tuesdays always follow #Mondays in order for the first one to be true.) Or you can #do as John did and quantify over all days. I think this is #what goes on in English, "today" really stands for "each day", #in the same way that "you" stands for "each person" in generic #statements like "if you put your hands on the fire, you burn #yourself". That really means "for every person x, if x puts #x's hands on the fire, x burns x-self". # #For every "today" x, if x is Monday, then "the tomorrow" of x #is Tuesday. TRUE # #For every "today" x, if x is Monday, then "the tomorrow" of x #is Wednesday. FALSE This is, in fact, what I said to McCawley when he came out with the examples in question. His response was "But the sentences *say* _today_, and _today_ means 'today'; it's only the _if_ that makes it seem as though it means something else". And I agree with him. We can ditch the deictics, though. If they're a redherring: A. "If Jorge had been born in Warsaw, he'd be a British citizen" =3D false B. "Jorge is british or not born in Warsaw" =3D true C. we could change A to: "Everyone is british or not born in Warsaw" =3D false but A and C are not equivalent, and we may be wishing to make a claim only about Jorge, not about everyone. So quanifying across possible worlds is not always avoidable. --And.
