On The Putnam's Philosophy Of Language

Putnam's philosophy of language includes realism theory,truth theory and meaning theory,the study of Putnam's philosophy of language on the basis of his realism.His realism has two stages witch include scientific realism and internal realism.The study of Putnam's language philosophy also in accordance with his realism views change,it divided into two stages witch include scientific realism content of language philosophy and internal realism content of language philosophy.Putnam is the main representative of scientific realism,his arguments about scientific realism from talking about the reference of scientific theory,he regards the philosophy of language and philosophy of science research as an harmony question.He acknowledged that scientific theoretical nouns have reference and admit the convergence of science theory.Putnam claims functionalism method is used to study philosophy of mind,he want through study the functional status of the computer to understand people's cognitive activities,and he designs with computers how to act as human cognitive and emotional activities.Putnam later realizes gradually,man's thinking and emotion is much more complex than computer,and he eventually abandoned the functionalism.Putnam claims the semantic externalism,he thinks psychology does not decide the extension.If people through a introduction events win the ability to use a noun,and when they use of words,the introduction of event is concerned every time,there'll be the causal relationship between use of the words and the introduction of events.Putnam put forward the hypothesis of division of lab of language,he believe that experts have special knowledge to determine a word reference.Putnam claims correspondence theory of truth in scientific realism period,he hope to answer the equivalent problem across the possible world witch is closely related to the truth through research modal problems,Putnam thinks microstructure is the entity equivalent standard,this is also the consensus of scientific community.Putnam reflects truth of positivism,he saw an axiom system can't meet at the same time these two requirements of "no contradiction" and "complete",defined truth with the set theory has certain limitation.In the period of internal realism,Putnam was influenced by Wittgenstein and the American pragmatism.He demonstrate the brain in a vat's words don't have the same reference as ours,and make a further negative in functionalism of philosophy of mind and puts forward the internal realism.Putnam used set theory to define the extension of a word,if a word has multiple meanings,the word has a set of multiple extension.Putnam processing the extension function witch in the context of a different language has different denotation into an extension relate to different speakers.Putnam arguments truth through the conceptual framework of relativity,because when we talk about the object must use concept and logic,so leave observer to talk about world is illegal.Putnam argues that in a given theory,we find out how to use the concept of “object”,“existence” and so on,the problem of how many objects are there in the world is only one answer.Putnam accepted common sense of realism,he sees a lot of thing in the world we can't be explanation and reduction in human rational,so he against through constructing a system form to an world's idealized explain.Putnam in the practice context to talk about truth,it's related to our understanding of language game.
