 Finally, even if direct reference is to be taken for granted and rigidity for names does follow from direct reference, one might not draw the conclusion that rigidity loses interest. Here is an analogy. Few would say that if the theory of special relativity, with all of its claims about the relativity of space and time, follows from the theory of general relativity, then special relativity loses interest because in that case, general relativity is what really matters: special relativity and much more just follow from it. There is evidently something wrong with this attempt to devalue the theory of special relativity. It would be better to say that part of what is interesting about general relativity concerns its implications for the relativity of space and time, as explained by the theory of special relativity: special relativity retains its interest as part of a larger, more fundamental theory. In the same way, rigidity might be said to lose no interest even if it is explained by something more fundamental.
