孪生地球思想实验的信息语义学解读及其争论

Explaining The Twin Earth thought experiment by A Semantic Theory of Information and its Debates

希拉里.普特南为阐明其外在主义立场而设计的孪生地球思想实验,近几十年来一直是内在主义者和外在主义者争论的焦点。作为外在主义的辩护者,美国哲学家弗雷德.德雷斯基通过信息语义学对孪生地球思想实验进行重构和解读,引发了他和内在主义代表人物福多之间的论战。在这场争论中,双方围绕孪生地球思想实验,不断引入新的材料和理论,就心理内容是内在的还是外在的、以及心理内容对行为是否产生因果作用等一些传统问题展开辩论,从而将这些问题的探讨拓展到更深、更广的层面。

The Twin Earth thought experiment which was designed by Hillary Putnam to clarify the position of his externalism,has been the focus of debates between the Internalism and Externalism in recent decades.As a defender of Externalism,Fred Dretske reconstructed and ex-plained The Twin Earth thought experiment by A Semantic Theory of Information,and this led him to argue with Fodor.As concerning the Twin Earth experiment,they mainly focused on such traditional questions as whether mental content is internal or external,as well as whether it will affect behavior or not,during that these questions have been extended to the further level.
