 Suppose that Dummett’s metaphor and constitution theses are both implausible. Would it follow that the arguments Dummett develops against semantic realism have no relevance to debates about the plausibility of realism about everyday macroscopic objects (say), construed as a purely metaphysical thesis as in (GR2)? It can be argued that Dummett’s arguments can retain their relevance to a metaphysical debate even if the metaphor and constitution theses are false, and, indeed, even if Dummett’s view (1973: 669) that the theory of meaning is the foundation of all philosophy is rejected. For a full development of this line of argument, see Miller 2003a and 2006.
