"The weapon of criticism cannot replace the criticism of weapons" is a famous saying of Marx and Engels. It means that it is not enough to criticize with words, and practical actions must be taken. ?
Marx wrote in the Introduction to Critique of Hegel's Philosophy of Right: "Of course, the weapon of criticism cannot replace the criticism of weapons, and material power can only be destroyed by material power; But once the theory grasps the masses, it will also become a material force. As long as the theory convinces people, it can grasp the masses; As long as the theory is thorough, it can convince people. The so-called thoroughness is to grasp the root of things. But the root of man is man himself. "
The philosophical thought embodied in this famous saying is the relationship between theory and practice. "The weapon of criticism can't replace the criticism of weapons" means that "theory can't replace practice". The weapon of criticism is the criticism of theory and Marxism's criticism of capitalist theory. The criticism of weapons is a criticism of reality and a criticism of capitalist society by the socialist revolution.
