摘要
..知態的封閉性原則在懷疑論的論證裡扮演很重要的角色，而有些哲學家站在反對懷疑論的立場，試圖去論證這個看似直覺的原則實際上是可以被拒絕的。在這篇論文，我將會試著去說明關於知態的封閉性原則，其概念乃源自於內在論與外在論之間的爭辯。而在傳統的知識論脈絡上，我們對於知識概念的了解主要是來自於內在論者的觀點，而許多懷疑論論證的不同形式，也是針對內在論者的傳統想法而發。本論文的目的主要是去論述大部分的內在論者傾向於接受此原則，但某些外在論者卻不這麼認為，且有不同的直覺與觀點，因此他們在反對懷疑論的立場上，也有不同的策略。最後，我們可以發現大部分不接受知態的封閉性原則的知識論者，基本上都是外在論者。

Abstract
..... . The epistemic closure principle plays an important role in the skeptical argument. Some philosophers, in order to defend their own position against skepticism, try to argue that this principle can be rejected even if it seems to be so intuitive. In this thesis, I want to explain the idea of the epistemic closure principle based on the debate of internalism and externalism. In traditional epistemology, the concept of knowledge is understood mainly from the internalist standpoint, many different forms of skeptical argument are actually directed to this internalist tradition. The purpose of my thesis is to show that most of internalists may tend to maintain the intuition of the principle, while some externalists feel unease about this intuition. Different intuitions and standpoints explain the different strategies against skepticism. We can witness that most epistemologists who dislike the epistemic closure principle are externalists.
