Abstract：As an integral part of Xi's Thought, “Four Greats”reflects the dialectical unity of the historical logic, realistic logic, theoretical logic and philosophical logic of the socialism with Chinese characteristics in the new era. The historical logic is concentrated on the historical inheritance of the Party's strategy for governing the country since the founding of New China. The realistic logic is concentrated on the realization of great dream, which is based on the reality of China and promoted by the great struggle, great project and great undertakings with the new historical characteristics. The theoretical logic is concentrated on the consistent following of the ideological line of emancipating the mind and seeking truth from facts. The philosophical logic is embodied in its recognition of the connection, the emphasis on contradiction and the people-centered development idea. Through the systematic analysis and grasp of the internal logic relations of“Four Greats”, we will further deepen our understanding of the profound implications of this thought.
