But not everyone would be happy with it. I think metaphysical eternalists insist that there is just one quantifier (i.e., 'exist' cannot be ambiguous, according to them).<BR/><BR/>Carrie: Right. However, the problem is that the interpretation appears to be ambiguous (between your two readings). Since it is ambiguous, it cannot be an adequate semantic analysis.Brit Brogaardhttps://www.blogger.com/profile/17944929071368873218noreply@blogger.comtag:blogger.com,1999:blog-31003419.post-1153135896000429692006-07-17T06:31:00.000-05:002006-07-17T06:31:00.000-05:00I'm not sure I'm seeing what the problem is.

There's Exists1, true of Socrates only during his lifetime, and Exists2, true of Socrates at any time. The two readings differ only in which existence predicate is used; the analysis of the tense si the same.<BR/><BR/>For the "persistence" case, it seems to me, the problem is similar: the hard part is to say what it is for objects to persist at a time t (maybe you need extra quantifiers that allow you to say "most things which exist at u (the current time) have existed for a short while").Richard Zachhttps://www.blogger.com/profile/10074252272606254341noreply@blogger.comtag:blogger.com,1999:blog-31003419.post-1153096074779913342006-07-16T19:27:00.000-05:002006-07-16T19:27:00.000-05:00Richard, I meant to reply to your reply to the oth...Richard, I meant to reply to your reply to the other case as well. Relatively untutored folks might say 'things persist' or 'the universe is 4-dimensional' or 'we are spread out in space and time; we always were, and we always will be'. But I don't see how the quantifier analysis could account for these cases.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-31003419.post-1153094989634137792006-07-16T19:09:00.000-05:002006-07-16T19:09:00.000-05:00Hi Richard,Thank you for your reply!

What about the following:<BR/><BR/>It will always be the case that Socrates exists<BR/><BR/>It might be argued that the sentence has two readings. For suppose 'Socrates exists' has two readings. One reading would be false, something like "Socrates is presently among us", and another would be true if metaphysical eternalism is true. But if 'Socrates exists' has two readings, then so does 'it will always be the case that Socrates exists'. It seems that you can't capture both readings (without radical paraphrasing) if you treat the tenses as quantifiers. It was this sort of problem I had in mind.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-31003419.post-1153092129781618432006-07-16T18:22:00.000-05:002006-07-16T18:22:00.000-05:00The analysis of the first sentence depends on your...The analysis of the first sentence depends on your analysis of "objects persist over time".
