Heidegger's deconstruction of Hegelian philosophy can be divided into three stages.In the first stage,Heidegger put forward the structure of"onto-theo-logy"in many works to describe the metaphysical characteristics of Hegelian philosophy,which has rich connotations and is applicable to all metaphysicians from Aristotle to Hegel.In the second stage,Heidegger summed up the characteristics of"onto-ego-theo-logy"in Hegel's Phenomenology of Spirit.He added the concept of"ego"on the original basis.Since Descartes,ego has been set up as subject,and Hegel is the completer of metaphysics of subjectivity.Later,in order to distinguish Hegel from other subjective metaphysicians such as Descartes and Kant,this paper argues that the concept of"absoluteness"must be introduced to highlight the characteristics of Hegelian philosophy,which constitutes the third stage of this interpretation.These three stages together constitute the basic characteristics of Heidegger's interpretation of Hegel's philosophy.
