The Grounding Of The Certainty Of The Subject's Cognition And Heidegger's Being

Since Descartes' "I think,I am" proposition,modern philosophy began a ideological movement of finding the certainty of cognition,One of the core problems during the period was the "I think" and the proof of the external objective world?This paper focuses on the solution to the related problems in Descartes,Kant and Husserl,analyse the basis of their theory and the process of argumentation,and makes a brief analysis of the interrelationship between their respective thoughts.By investigating Heidegger's response to this question,with the restoration of the original phenomenon of the relationship between the subject and the object,he demonstrates the priority of Da-sein which is already in the world,and takes the overall structure of the Care as a clue.The original problem finally comes to the problem of Being.We finally concluded that: in the view of the problem of the Being,if we follow the unity of the structure at the beginning of meeting of Da-sein and the world and respect the original phenomenon of truth,then the distinction between the subject and the object,which is always thought as the premise of epistemology,will naturally be digested ? At the same time,with this presenting of the transcendent exposition of the time based on the relationship between Da-sein and Being,It will make this issue a new understanding,and then open the more primitive level of inquiry.
