Solving the relationship between man and the world from practice is the essence and key to realize the great philosophical change of Marxist philosophy. It is practice that provides people with the object of understanding. Therefore, in practice, people not only know the world, but also transform it, creating a human world and a natural comfortable world based on nature. Therefore, practice has not only epistemological significance, but also world outlook significance.
Important significance
Practical viewpoint is the foundation of Marxist philosophy, which runs through all dialectical materialism and historical materialism.
Marx's contribution to philosophy is to introduce the concept of practice into philosophy, to link philosophy with the liberation of the modern proletariat (working class), and to apply this philosophy to the social and historical field, which leads to the emergence of historical materialism. Marx analyzed and studied the economic basis of discovering surplus value in capitalist society, and pointed out that the class struggle between the proletariat and the bourgeoisie will inevitably lead to the dictatorship of the proletariat, which is the transition and evolution from capitalism to communism.
