Feuerbach's criticism of Hegel declared the end of German classical philosophy. As the direct successor of German classical philosophy, Marxist philosophy has stepped onto the stage of world history. Marx and Engels fully affirmed the positive achievements of German classical philosophy, criticized Hegel's idealism, liberated dialectics from the shackles of his mysterious philosophical system, criticized Feuerbach's humanism and absorbed the basic core of his materialistic philosophy. They organically combined dialectics with materialism, founded dialectical materialism and historical materialism, and opened up a new era in the history of philosophy. The great historical significance of German classical philosophy lies in that it provides a theoretical premise for the emergence of Marxism and becomes one of the theoretical sources of Marxist philosophy.

German classical philosophy has a great influence on the development of philosophical thought in the future. A group of philosophers denied dialectics and focused on the idealism and agnosticism of German classical philosophers. Neo-Kantians such as O. Lippmann, F.A. Langer, H. Cohen, P. nuttall, W. Vendel, H. Likert, etc. , 19 came into being in 1960s and 1970s, and some schools of modern philosophy, such as F.H. Bradley, B. Bao Sangkui and B. French philosopher Cove and hippolyte interpreted Hegel with existentialism, trying to combine Hegel's philosophy with existentialism.

German classical philosophy is not only a concentrated projection of the spirit of the times and national spirit, but also has theoretical value beyond the times in the history of philosophy, which is the thought of a master. Kant's critical philosophy's summary of empiricism and rationalism, and Hegel's summary of previous philosophical systems all mark a great leap in western philosophy.
