Researches On The Problem Of Presupposition Projection From The View Of Anaphora

Presupposition is the intersective theory of Linguistics and Logic.Text research and communication both need presupposition to express what people already known.The projection problem of presupposition is a highly controversial topic at present.If we solve the projection problem of presupposition,we can analyze the content and understand the text better.Projection problems involve the relationship between the presupposition of compound sentences and the presupposition of clauses in compound sentences.From the beginning of presupposition theory,foreign scholars have given many methods to the projection problem,such as the "Cumulative Hypothesis" of D.T.Langendoen and H.B.Savin,the PHF theory of L.Karttunen and Mental Space theory of G.Fauconnier.However,each of these methods has its own problems,such as the “Cumulative Hypothesis”,which simply stacks the presupposition of compound sentences into the sum of the presuppositions of clauses.PHF theory and Mental Space theory have a large number of counterexamples.S.Kripke gave objective evaluation for the above solutions,pointing out the reason why these solutions are unconvincing is that they all ignore an anaphoric element in natural language that ought to have been taken into account.He holds that some language components can trigger presuppositions,they often refer to some anaphoric information.This kind of phenomenon is similar to pronominal anaphora.Ignoring this factor makes the solution of projection problem unsatisfactory.On the basis of Kripke's analysis,this paper analyzes the relationship between anaphora and presupposition,explores the local situation of projection problem,and review V.Sandt's presupposition-as-anaphors theory,by using pronoun-like anaphora resolution to solve presupposition projection problems.This paper use the method of comparative and analysis to study the projection problem of presupposition.And it also uses the method of history and logic to explain he importance of “anaphora”.It focus on the theory of S.Kripke,V.Sandt and E.Krahmer.They provide a new angle of view to solve the projection problem of presupposition whichis closer to the process of understanding natural language.
