按照基础主义的认识辩护理论,我们的信念总体中存在着一种地位特殊的信念,即“基本信念”。而美国哲学家约翰·波洛克则认为,基本信念是不可能存在的。它只是一种的虚构。然而,在对波洛克的论证过程进行细致地分析之后,我们就可以发现:其实,波洛克并不是在否定基本信念,而只是在对基本信念进行一种新的解释而已。尽管如此,波洛克的整个批判过程却使我们认识到:正确理解“理由”这个概念才是解决信念辩护问题的关键。 According to the fundamentalist theory of defensive understanding, there is a special belief in our belief that “the basic conviction”. The American philosopher John Pollock believes that basic beliefs can not exist. It’s just a fiction. However, after careful analysis of Pollock ’s argument process, we can find out: In fact, Pollock did not negate the basic conviction, but only made a new interpretation of the basic conviction. Nevertheless, Pollock’s entire critical process has made us realize that a correct understanding of the “reason” concept is the key to resolving the issue of belief defense.
