 As a consequence of these structural features of the metasemantic interpretation, metasemantic diagonal intensions play none of the basic explanatory roles attributed to 1-intensions by proponents of generalized 2D semantics. In particular, (i) diagonal intensions do not figure in a compositional semantic theory, (ii) they do not reflect stable aspects of linguistic or conceptual competence, and (iii) they do not represent apriori accessible reference-fixing conditions for the subject’s words or thoughts (Stalnaker 1999b, 2004 , 2007).
