本文首先，我們要考察德瑞達和僧肇的解構主義是如何在他們哲學寫 作中的詞匯法和構句法中得到體現的。其次，我們將考察德瑞達和僧肇是如何通 過他們的詞匯和構句的解構，來展現通過語言以把握神學本體之本質以及邏輯本 體之本質的不可能性，以及他們是如何進而雙重否定各自哲學傳統中的名本體說 和物本體說。最後，我們將看一看德瑞達和僧肇是如何以相似的「無」的術語， 從不同的解構途徑，來總結他們的雙重否定的理論。

In this paper, we will first examine how Derrida and Seng Zhao express “deconstruction” through the grammatology and syntax of their philosophical writings. Then we will see how Derrida and Seng Zhao, by deconstructing their grammar and syntax, show the impossibility of grasping the essence of theological ontology and the essence of logical ontology. We will also see how they thereby negate both the nominal ontology and the material ontology in their respctive philosophical traditions. Finally we will see how Derrida and Seng Zhao, from different deconstructive ways but with similar terms of “nonentity”, conclude their theories of double negation.
