In the materialist view of history and Marxist view of revolution, both social revolution and self-reform are essential components. Across different periods of social revolution, the agents, targets, methods, and pathways of social revolution vary significantly. Similarly, for different revolutionary agents, the objects, substance, approaches, and trajectories of selfreform also differ in their revolutionary activities. Precisely due to these variations in revolutionary objects, substance, methods, and pathways, selfreform manifests unique value and significance distinct from social revolution in promoting historical progress and advancing human civilization. The process of social revolution simultaneously embodies the continuous advancement and realization of selfreform by revolutionary agents. For revolutionary classes or political parties, their social revolution and selfreform exist in dialectical unity. Selfreform takes shape and is realized through social revolution, while simultaneously driving and guiding social revolution. In the new era and on the new journey, guiding social revolution through the Partys selfreform serves as the principal revolutionary approach of the Communist Party of China (CPC) in the new era, the innovative revolutionary philosophy of the CPC in the new era, and the primary driving force of sociohistorical development in our times.
