 There are a number of lines of thinking that converge on the conclusion that (1)–(4) share the same assertoric content even though they differ in ingredient sense. As already suggested, some might find it natural to take (1)–(4) as expressing the same “semantic content” in some meaningful sense (perhaps the only meaningful sense): if so, Dummett’s distinction indicates how one might coherently maintain that position. Such a position might be especially natural in view of “descriptive names,” like Evans’ famous ‘Julius’, which is a rigid designator for whoever invented the zipper (Evans 1979). It might seem natural to say that ‘Julius is an inventor’ has the same content as ‘Whoever invented the zipper is an inventor’, even though the former is contingent and the latter necessary. Evans himself suggests that such pairs of sentences “have the same content, despite their modal differences” (Evans 1979, p. 187n.10).
