摘　　要：不败性理论曾被用作知识论中葛梯尔问题的解决方案之一,但该方案并未能解决葛梯尔问题。葛梯尔难题对传统知识定义的挑战是不可回避的,该难题的复杂性体现在使用演绎闭合原则和偶然真理方法来分析不败性理论的失败上。因此我们应谨慎使用"知识"这一概念,并考虑到反例的可能出现。Defeasibility theory of knowledge has been treated as a solution to Gettier problems,though it failed. The challenge on traditional definition of knowledge from Gettier problems cannot be avoided,because of the complicity of these problems which could be entailed clearly by the comparison between invalidity of CP principle,contingent truth theory and fail of defeasibility theory. Given reasons mentioned above,one should define ＂knowledge＂more carefully,while counter-example should also be taken into consideration.
