The boundary of language:Brandon's anaphora theory from the perspective of situational theory
Through the inference network provided by the theory of anaphora,with"sub sentences"as the core,Brandon transformed the relationship between"language-world"into the relationship between"language-language",providing a new approach to characterize referential relationships.However,Brandon's theory of anaphora faces two main difficulties:"referential opacity"and"non co referential anaphora".To address these issues,Ricardo's"situational theory"will be adopted to optimize the theory of anaphora,introducing σ-Heterogeneous structure is used to solve the difficulties faced by Brandon's anaphora theory.Firstly,modal operators are inserted into the anaphora chain to reveal the contextual structure of sentences,strictly distinguishing between the contextual and semantic content of sentences;Secondly,clarify the anaphoric chains and their logical relationships of different cognitive subjects in different contexts;Finally,the inexhaustible"ultimate perspective"and the irreducible real world located outside the anaphora chain are also presented in a situational manner.In short,"language","mind",and"world"are essential components in anaphoric relationships.
