Assertion: expression | /r/HasAspect | same reference
Facets:
Source sentences:
text: Moreover, from the point of view of the theory of reference, (5) and (6) are just the same: they differ only in the substitution of “renates” for “cordates”, and these expressions have the same reference (because they stand for the same function from objects to truth-values).
text: (7) and (8) differ only with respect to the italic expressions and, as we noted above, these expressions have the same reference.
text: Our worry was that, since these expressions have the same reference, if meaning just is reference, then it seems that any pair of sentences which differ only in the substitution of these expressions must have the same truth-value.
