谈谈非形式逻辑问题

1 批判性思维就是通过积极、谨严的分析、评价,以辨别、确定某一论题、论述的是非、正误的思维过程,也就是论辩思维。非形式逻辑是有关批判性思维———论辩思维的逻辑。2 非形式逻辑仍然以思维形式为研究对象。它之所以叫非形式逻辑,只是说它是运用自然语言进行论述的,目的不在于建立形式化的逻辑系统,而是要提高人们在日常生活和工作中的论辩能力。非形式逻辑是非数理逻辑的逻辑。3 非形式逻辑是对数理逻辑的否定,是对传统逻辑的否定的否定———在更高基础上的对传统逻辑螺旋形上升的复归。4 非形式逻辑的出现证明所谓的"传统逻辑已经无用,我国逻辑现代化就是要用数理逻辑取代传统逻辑"的说法是错误的。5 今后我国高校一般文科应以讲授非形式逻辑为主,应组织力量尽快编出一批非形式逻辑教材。

On Nonformal Logic

1. Critical thinking is the process of judging right and wrong or distinguishing truth from falsehood through active and careful analysis and evaluation. It is also the process of argumentative thinking. Nonformal logic is just about the logic of critical thinking --- argumentative thinking. 2. Nonformal logic takes ways of thinking as its object of study. It justifies its existence with its exposition in natural language, aiming at promoting the argumentative ability of people in everyday life and work, rather than establishing formalized logic system. Nonformal logic is the logic of nonmathematical logic. 3. Nonformal logic is the negation of mathematical logic, and also the negation of the negation of traditional logic - a spiral and exalting return to the traditional logic. 4.The existence of nonformal logic shows it is wrong to say that traditional logic is outmoded and that modernization of logic in China means to replace traditional logic with mathematical logic. 5. It is necessary to take nonformal logic as more important in the course design of universities in China and to compile textbooks on nonformal logic as soon as possible.
