Adhere to the unity of dialectics and materialism. Engels believed that because dialectics broke through the narrow limits of formal logic, it contained the seeds of a broader world view. Dialectics is a scientific method to promote social management. Social management must pay attention to dialectics. Without understanding dialectics, it is difficult to really manage society well. To stress dialectics, we should deal with the relationship between vitality and order, take a comprehensive view of the situation of social stability, accurately grasp the work of maintaining social stability, and adhere to systematic governance, legal governance, comprehensive governance, and source governance. Taking the maintenance of network security as an example, we should first know where the risk is, what kind of risk it is, and when the risk occurs, so as to achieve the goal of "the intelligent listen to the silent, the intelligent see the invisible", and standardize the maintenance of the healthy development of the Internet. To improve the ability to prevent and defuse major risks, we should not only grasp the trend of accelerating the world's multi-polarization, but also pay attention to the trend of in-depth adjustment of relations between major countries; We should not only grasp the general trend of the sustainable development of economic globalization, but also pay attention to the trend of the profound evolution of the world economic pattern; We should not only grasp the overall stability of the international environment, but also attach importance to the complex situation of international security challenges; We should not only grasp the general trend of exchanges and mutual learning among various civilizations, but also attach importance to the reality of the interaction of different ideologies and cultures. Only by dialectically understanding and analyzing problems can we learn experience, deepen understanding, analyze and judge various risk factors we face, summarize effective methods and strategies to deal with major risk challenges, and organically integrate dialectics and materialism. Adhere to the unity of the two-point theory and the key theory. The unity of the two points theory and the key point theory is the specific development of the contradiction analysis method, and the contradiction theory is the unity of the two points theory and the key point theory. To analyze social phenomena, we should follow the dialectical thinking of "two points are the key points, and the key point is the key point of the two points" to find the key to solve the problem. Adhering to the unity of the two-point theory and the key theory, correctly handling the dialectical relationship between the main and secondary contradictions and the main and secondary aspects of the contradiction, we need to focus on the key links of the overall situation, at the same time integrate resources, coordinate forces, and deal with other aspects of work in a hierarchical and step-by-step manner. They are good at analyzing problems from both positive and negative aspects and looking at problems in two. They are also good at grasping key issues, key factors and key factors. In the face of complex situations and onerous tasks, we should first have a holistic view and have a clear understanding of all kinds of contradictions. At the same time, we should give priority to solving the main contradictions and the main aspects of contradictions, so as to drive the solution of other contradictions. We should adhere to the "two points theory" and see not only the positive side of the international and domestic situation, but also the negative side; From the bad side, do the best
