In Hegel’s view of reality, the state is a form of reality and the reality of ethical ideas. According to its reasonable essence, the contradiction between “private interest” and “public good” in civil society can be solved by following the universality of the state. Marx’s critical transcendence of Hegel’s view of reality embodies in saving “reality” from the concept of state and transferring it to the reality of civil society, forming an overall view of “reality” and solving real contradictions. Marx understood reality from “human perceptual activity”. For the revolutionary practice, all realities are transient existence under certain historical conditions, and the contradiction of reality is solved in this practice. The critical and revolutionary requirement of practice is to constantly change the existing situation, and reality is the reality that practice is producing and its development process. The continuous self-denial and future-oriented social practice calls for the active exploration of a higher reality, that is, the reality of communism, in the practice of constantly changing existing history.
