Originated from the analysis of natural language, the development of logics will inevitably lead to the creation of formal language. From the point of view of logics, it is always worth to explore and study the new problems of living natural language. There is a question in using language that is whether or not it is logical. Neither thinking nor logic can be divorced from language, but there is difference between the two. During the process of thinking, with ambiguous concept, misjudgment and wrong inference, the effect of thinking will be affected; consequently, people always find their utterance fail to convey their ideas, and the sentences they make seem less flowing and fluent. However, with the help of logic, people can express themselves with language freely and achieve the expected effect. Take English and Chinese for example, the differences and similarities between the two languages become obvious when logic is taken into consideration. When people are in diverse cultures, the ways they express themselves are totally different, which can be attributed to different cultural backgrounds, despite that we have the same thinking ability, thinking methods and thinking process. Thus, the difference in language exists exactly in the differences of culture and thinking habits. It's our motivation to further and perfect the analysis of logical semantics in order to avoid the wrong expressions for lack of logical analysis or inappropriate meaning because of blind copying. This thesis aims to analyze the relations between logical semantics and various disciplines, probe the application and development of logical thinking in various fields. |
