对笛卡尔“我思故我在”的重构及反思

On the Reconstruction and Reflection of Descartes' "I Think,therefore I Am"

笛卡尔将整个的传统知识大厦推倒重来,运用普遍怀疑的方法,在认识论上进行一次大胆而又审慎的重构。通过对"我思,故我在"命题的逐字分解和辨析,发现该命题的关键不是"在",即我的存在,而是"知在",即认识到我的存在。在此基础上提出对"我在"的两种逻辑悖论的论证策略,即违反不矛盾律策略及无穷倒退策略。进而从怀疑的对象、内容到怀疑的过程本身来回答我是否真的无法怀疑自己的怀疑这个棘手问题。最后回答两个相关问题:根本上应当如何看待怀疑,以及逻辑自身是否应当受到怀疑。

Descartes tries to reconstruct the knowledge system epistemologically. The key words in the famous proposition made by Descarte ＂I think, therefore I am＂ is the word ＂being＂ instead of ＂knowing being＂. The paper provides two arguments about ＂I am＂ from the logical paradox point of view and answers the question that if people can doubt their doubting and if the logic itself can be doubted by people.
