Materialist dialectics is a kind of Marxist philosophy, which emphasizes starting from objective things, taking objective facts as the basis, and revealing the essence and internal relationship of things through in-depth study of the internal contradictions, interactions and changes of things. The essence of materialist dialectics lies in providing scientific guidance for human beings to understand and transform the world through the revelation of the inherent contradictions and changing laws of things.
First of all, materialist dialectics holds that things are driven by internal contradictions, which are the fundamental driving force for the development of things. In the internal contradiction of things, the unity of opposites is one of the most basic laws. The law of the unity of opposites shows that everything has its inherent opposites, which are both interdependent and mutually exclusive, thus driving the development and change of things. For example, in an ecosystem, there is a food chain between various organisms, and the unity of opposites between them maintains the ecological balance.
Second, materialist dialectics emphasizes the universal connection and interaction of things. Things do not exist in isolation, but are in a universal connection, which manifests itself in the interaction and influence of various factors. For example, climate change affects the balance of ecosystems, and changes in ecosystems also have an impact on the climate. This interaction and connection shows that any change in one thing will have an impact on other things, so we need to consider the connections and roles between various factors holistically.
Third, materialist dialectics holds that things change in a regular manner. The inherent contradictions and interactions of things will lead to the change and development of things, and this change is regular. Through the study of the internal contradictions and interactions of things, we can reveal the law of change of things, so as to better control the development of things. For example, in economics, there are laws in the relationship between supply and demand, and through the study of this law, we can better ** market changes and formulate economic policies.
Finally, materialist dialectics emphasizes that practice is the only criterion for testing truth. In practice, we can verify the authenticity and reliability of theories through observation, experiments, and summarizing experience. Only theories that have been tested in practice are reliable, so we need to constantly revise and improve theories through practice. For example, in scientific research, we can verify the correctness of a theory through experiments, and if the experimental results do not match the theory, we need to revisit the theory and revise it.
To sum up, the essence of materialist dialectics lies in providing scientific guidance for human beings to understand and transform the world through the study of the internal contradictions, interactions, laws of change and practical tests of things. By applying the principles of materialist dialectics, we can better understand the essence and internal relationship of things, so as to better deal with various complex problems and challenges.
