| In the field of philosophy, truth is an important concept, while in the field of logic, truth is a central concept .for, truth is the research object of logic .In Frege 's word, logic is just to pursuit truth. Many logicians and philosophers provided their unique ideas about truth, which formed different truth theories .For the convenience purpose ,the researchers classified truth theories according to different standards and different starting points .This paper refers to Michael P.Lynch's classification .He classified truth theories into two kinds :robust theories and deflationary theories .The latter is the research object of this paper."Deflationary theories" is a name for a family of views .All the views agree that truth has no nature .The major views are redundancy theory, perfomative theory, prosententialism and minimalism etc .Any deflationary view of truth is comprised of two basic components .The first is metaphysical thesis: truth has no nature . This is often put by saying that "truth" does not express a property .The second component is semantic. Since "true" dose not pick out a property that all true statements share, the deflationist must explain the meaning of the word "true" and (or) the purpose of having such a word or concept in our language. Various deflationary positions spell out these aspects of the position in different ways.After fixing in what sense we are going to talk about truth, the paper specifically introduces and analyzes deflationary theory's origin and contents. And it also involves the relationships among various deflationary views .In the last part of this paper, some commends are made on deflationary theories of truth. |
