非形式逻辑视野下的论证评价理论

On Argument Evaluation from A Perspective of Informal Logic

论证可分为形式论证(人工语言论证)与非形式论证(自然语言论证)。前者是形式逻辑的研究对象,后者是非形式逻辑的研究对象。我们从几个代表性逻辑学定义出发,分析了非形式逻辑产生的背景,讨论了形式逻辑与非形式逻辑的区别,并从非形式逻辑角度探讨了自然语言论证评价的标准。

Arguments are normally divided into formal and informal ones.The former is concerned with by formal logic while the latter is focused on by informal logic.In this paper,we first discuss several definitions of logic,analysis the background of the rise of informal logic,study the difference between formal and informal logic,propose three criteria to accessing informal arguments-logical,dialectical,and rhetorical-from informal logic.
