 Proponents of G2D were influenced by Stalnaker’s early papers developing the 2D framework, and their views are often presented as continuous in motivation and form. But there are important theoretical consequences that flow from the choice between 2D metasemantics and generalized 2D semantics. Indeed, Stalnaker himself is a vocal critic of generalized 2D semantics, rejecting its commitment to the semantic status of 2D matrices, its commitment to apriori conceptual analysis, and its internalist approach to reference determination.
