 As pointed out when presenting the structural rule in  Section 2.1.1,  the   Formal Rule is one of the most salient features of the dialogical framework. With this rule the dialogical approach comes with an internal account of elementary propositions in terms of interaction only, without depending on metalogical meaning explanations for the non-logical vocabulary. More prominently, this means that the dialogical account does not rely—contrary to Hintikka’s GTS games—on the model-theoretic approach to meaning for elementary propositions. Hence, just as Lorenz (2001) clearly stated, the dialogical notion of proposition does not assume truth-conditional semantics.
