The Fourth Plenary Session of the Nineteenth Central Committee of the Communist Party of China proposed a major issue of the modernization of the national governance system and governance capabilities. In this historical process, dialectical thinking can undoubtedly provide thinking guidance and practical initiative. However, Marxist dialectics has been challenged and discredited countless times in history. The so‐called "orthodox Marxism" represented by the Second International explained the vulgarization of Marxist theory, abandoned dialectics, and promoted mechanical materialism and economic determinism. Western liberals and some leftist thinkers deny the existence of socialism. In the face of the "intellectual crisis," Merleau‐Ponty proposed "Dialectics in Action" and drew on the dialectics of Hegel, Weber, and Lukács. He proposed that dialectics only exists in the synthesis of subject and object, emphasizing the practical role of dialectics, which is a "free adventure" of dialectics in the 20th century. Clarifying the connotation and differences of Lukács and Merleau‐Ponty dialectics can improve the philosophical thinking of the governance of socialist countries with Chinese characteristics.
