Ben C said:It is clearly bogus.
Well, I'm not much into this whole possible worlds stuff, but if I were,
this kind of thing might pose some problems.
You'd have to clarify that "the library" and "it" in the sentence, "the
library is bigger than it is" refer to a single thing in only one world.
And for that reason, that sentence is senseless.
But in the sentence "the library might have been bigger than it is" they
have to refer to instances of the same thing in different worlds, and
thus that sentence does make sense.
Except (and this is one of the natural criticisms of the Lewis
theory) if the reference is really to two different things (never
mind that they are instances of some further class or universal),
then it is not *really* the library we are talking about that we
say could have been different. It would, so the criticism would
go, be like saying that Hitler might have been a saint-like
figure because there was another very similar looking character
called Hitler somewhere else who was saint-like. Not quite what
is *meant*, the sense is that the one and only Herr Hitler,
himself, might have been different.
Better rush, I can hear Gus coming... <g>
