I think what's being lost here is the distinction between denotation and connotation. The time-
travel example treats "the same day as" as "identical denotation." Denotations are invariant under
"normalization" or "canonicalization," whereas connotations are not. If A makes a statement in
which he nominates a particular geographical region as "Israel" and B makes a statement in which he
nominates that same region as "occupied Palestine," both statements denote the same region, and
will continue to denote that same region if the names are "normalized" to a listing of numerical
coordinates. But the information contained in the different connotations will have been lost; the
normalization is not a reversible mapping. Swapping the nominations in A's and B's statements will
alter their meaning. Sure, the transformation will have a fixed point or two; the swap hasn't
destroyed your ability to determine which page of your atlas the region in question appears on.
But I somehow doubt that the "applications semantics" that A and B were addressing were quite that
If I write some character data in an XML document using < and > in several places, that data
has the exact same denotation as if I had used a CDATA marked section containing pointy brackets.
But the connotation could be different. I might have chosen the CDATA section to emphasize the
opacity of that particular character data to some process. The computer doesn't care, but all data
ultimately begins and ends as something meaningful to a human.
