  The Demonstrative Theory is both bold and radical. It triggered an entire cottage industry devoted to criticizing and defending it. For proponents, see, for example, Partee (1973), Garcia-Carpintero (1994, 2017, forthcoming), Cappelen and Lepore (1997b), McCullagh (2007), Predelli (2008); for critics, see just about anyone else writing on quotation after 1979.
