索绪尔、德里达和皮尔士符号理论综述

语言具有符号性，索绪尔认为语言符号是能指和所指的结合体，其关系是任意的，约定俗成的，语言结构的消极区分是符号意义的来源，德里达继承了索绪尔的二元符号模式，认为语言符号的差异是无限的，其意义是不确定的。皮尔士则认为外部世界是符号意义的来源，把符号分为三类。三的符号观反映在三种符号模式中。

A Review on Sign Theories of Saussure,Derrida and Peirce

Languags has sign-character. Saussure's view is:sign is combination of signifier and signified, with their arbtrary relationship. Its meaning depends on the negative differentiation in the language system. Derria succeeds Saussure's division of sign. but he owns the idea that the difference between language sign is undefinite, so its meaning is unsure. Outside world is the source of sign's meaning , according to Peirce, signs can be placed in to three classes. Three sign models are the reflection of their views on language sign.
