马里翁认为在笛卡尔的哲学中存在着两种不同的本体—神学—论思想,一种以自我为基础(其基本的表达式是“ego cogito,ergo sum”),一种以上帝为核心(其基本的表达式是“ego sum,ego existo”),前者是一种并不完备的形而上学,后者则展现了笛卡尔的一种成熟的形而上学思想。但是,关于笛卡尔的这种成熟的形而上学思想及其体系,马里翁在其《笛卡尔哲学问题:方法与形而上学》和《笛卡尔哲学问题II:自我和上帝》中分别给出了两种并不相同的解释,本文认为我们可以大体上认可马里翁的第一种解释,同时应该对他的第二种解释保持谨慎态度。 Marion believes that there are two different types of ontology-theology-theory in Descartes’s philosophy, one based on ego (whose basic expression is “ego cogito, ergo sum”), (The basic expression is “ego sum, ego existo”), the former is an incomplete metaphysics while the latter shows a mature metaphysical thinking of Descartes. However, with regard to this mature metaphysical thought and its system of Descartes, Marion provided two separate points in his “Cartesian Philosophical Problems: Methodology and Metaphysics” and “Descartes Philosophy II: Self and God” Different from the explanation, this article argues that we can generally recognize Marion’s first explanation, and should be cautious about his second explanation.
