Hegel's philosophy is not only the main object of Marx's criticism,but also an important source of the formation of Marxist philosophy.In the process of criticizing Hegel's philosophy of the state,Marx found the revolutionary thinking hidden in it,and used it as a breakthrough to clarify that the real state is in line with the concept of the state and is a"real community"with rationality.At the same time,Marx also"recognized"the revolutionary thinking contained in Hegel's view of the state,and combined it with the communist movement to realize human freedom and liberation.Therefore,a deep understanding and grasp of the philosophical change relationship between Marx and Hegel is conducive to the further improvement and development of Marxist philosophy.
