克里普克论知识悖论

知识悖论及其解决涉及到知识论的核心问题。克里普克在一篇新作中对意外考试悖论进行了深刻分析,并指出这一悖论的产生是由于错误地使用了"知识的持久性"这一前提,并以此为基础提出了一种新的知识悖论,即独断论悖论。通过分析可见,克里普克对"知识的持久性"的反驳以经典的知识论为框架,面对经典知识论所遭受的强有力的挑战,克里普克对意外考试悖论的解决缺乏可靠的理论支撑。知识悖论触及的是知识论的核心问题,任何尝试性的解决方案都要重新思考知识的本质到底是什么。

Kripke on the Paradoxes of Knowledge

Paradoxes of knowledge and their solution involve core thesis of epistemology.In his latest paper,Kripke analyzed the surprise examination paradox deeply,and pointed out that this paradox was produced by using a false premise,which says that once someone knows a proposition,he will know it at any later time.Through analysis,we can conclude that Kripke’s refutation to that premise mainly based on classical theory of knowledge,namely JTB.Faced with forcing criticism of JTB,it’s obvious that Kripke’s refutation lacks theoretical support.Because of its connected with core thesis of epistemology,any solution to paradoxes of knowledge will re-exam what’s the knowledge essentially.
