This book is part of the “Integration of Marxism with China’s Excellent Traditional Culture” series. Guided by President Xi Jinping’s speech at a meeting on cultural inheritance and development, the book explores, from a historical and theoretical perspective, the compatibility and integration of Marxism with China's excellent traditional culture in areas such as views on practice, epistemology, materialism, dialectics, historical views, and conception of freedom. The “second integration” represents a new liberation of thought, marking a significant innovation in both the basic principles of Marxism and cultural studies. The “second integration” is not only a crucial path to advancing Marxism in the Chinese context, building “modern Chinese civilization” and the “cultural form of the Chinese path to modernization,” and realizing the great rejuvenation of the Chinese nation, but also opens up a bright future for the localization of Marxism and the modernization of traditional culture on a global scale.
