逻辑多元论与多值逻辑

Logic Pluralism and Many-valued Logic

关于逻辑的性质,一般有三种观点:一元论,多元论和工具论。逻辑一元论把所有逻辑都归结为一种逻辑,这种分类方法往往导致只承认一种逻辑,即经典逻辑,否认多值逻辑及其它非经典逻辑的存在价值。本文通过分析指出多值逻辑可以有直观解释和实用价值,逻辑一元论无视这一事实会阻碍逻辑学的发展。由于工具论也必须在一元与多元之间作出选择,所以本文提出只有持逻辑多元论才能有利于逻辑学的发展。

On the property of logic,there are three ideas,namely logic monism,logic pluralism and logic toolism.Logic monists think that all kinds of logics belong to one logic.This idea will lead to regarding the classical logic as the sole logic and denying the value of many-valued logic and other non-classical logic.Pro- fasser Through analysis,the paper show that many-valued logic has intuitive interpretation and practical val- ue and that monism,denying such a fact,will hinder the devdoprnent of logic.Because toolism must make a choice between monism and pluralism,I insist that only when we persist in pluralism can logic develop rapidly.
