"事实-价值"二元论研究——元伦理学角度对"事实一价值"二元论的深化

＂是-应该＂问题逐渐演变为事实命题与规范命题之间关系的问题,对道德知识的考察从过去的经验论证或先验论证,转向了对伦理语言的结构及其含义进行逻辑分析和语义分析。＂是＂与＂应该＂之间的不同又被进一步发展成为事实与价值二元分立,尤其在元伦理学的创始人摩尔及情感主义那里得到更加深入的论证和重大的发展。摩尔的＂自然主义谬误＂、＂善不可定义＂、＂摩尔的开放问题论证＂以及情感主义的无意义的价值判断等思想,是对休谟关于事实与价值关系的问题的补充与发展,深化了休谟问题。

Research on "Fact-value"Dualism

＂To be or Should＂ question has evolved into a relationship between the fact proposition and the regulation proposition.The study of moral knowledge has changed from experience demonstration or prior demonstration to the logical analysis of the structure and connotation of language.The difference between ＂To be＂ and ＂should＂ has developed into the dual separation between fact and value,especially in the founder of metaethics---Moore,it has got a great development.Moore＇s thought of ＂naturalistic fallacy＂ and ＂goodness cannot be defined＂ is the development and supplement to Hume＇s law of fact and value,and further enhances Hume＇s question.
