A Study On Theory Of Pragmatic Presupposition And Its Application

Presupposition is a ubiquitous phenomenon in the language world.It was first put forward by Frege and then studied by Russell.But it was Strawson who gave the concept a more scientific content.Pragmatic presupposition arises from the need of presupposition's own development.Pragmatic presupposition is one of the important topics in pragmatics.The theory of pragmatic presupposition mainly includes the definition,characteristics and functions of the connotation of pragmatic presupposition,as well as the relationship between pragmatic presupposition and context,special conversational implicature and semantic presupposition.In speech communication,the speaker and the listener take pragmatic presupposition as the premise to realize the effective transmission of information.Therefore,pragmatic presupposition is the necessary condition for successful communication and the common background information of both sides.Pragmatic presupposition is all presuppositions in specific context,so pragmatic presupposition depends on context.Pragmatic presupposition and special conversational implicature represent both known and unknown information in the same sentence.Pragmatic presupposition is the basis of understanding special conversational implicature.When a sentence is used in actual speech communication,its semantic presupposition will be transformed into pragmatic presupposition,so the basis of pragmatic presupposition is semantic presupposition.Pragmatic presupposition has the characteristics of consensus,appropriateness,subjectivity,unidirectionality,revocability,concealment and non-conventionality,which are the basis for distinguishing it from semantic presupposition.The functions of pragmatic presupposition include cohesive function,simplified function,auxiliary function and decisive function,which make it play an important role in daily speech communication and written expression.Pragmatic presupposition theory is of great theoretical significance to logic and pragmatics,and can be used to solve problems in logic and pragmatics.Pragmatic presupposition theory has wide application value.It can be used to analyze the presupposition of natural language sentences and help people to achieve effective speech communication.
