After reading Chairman Mao’s theory of practice and contradiction, it was the first time to systematically come into contact with the methodology of dialectical materialism, and I deeply felt its power and nature. Combining my own previous experience and understanding, I refined the view of cognitive derivation.
From Pavlov’s dog bell experiment[1] to Festinger’s cognitive dissonance theory in the 1950s[2], to the Stanford prison experiment led by Professor Zimbardo in 1971[3], this A series of psychology students' physical experiments that broke expectations reveals step by step that the role of people's psychology does not seem to be what most people think. In fact, this seemingly important psychological discovery was actually put forward by Marx, Engels and others from a sociological point of view two centuries ago and perfected it into a theory. Later, Lenin, Stalin and others improved it through practice. After being introduced to China, it was collected by Mao Zedong, combined with the heritage of Chinese traditional culture, and developed into Mao Zedong's thought of materialist dialectics. The formation of this theory stems from these people's summary of the social phenomena they observe and the social movements they practice based on the theory. And this reasoning guided the founding of the Communist Party of China and solidly completed the miracle of domestic capital accumulation.
Dialectical materialism is a set of self-consistent methodology, which can effectively guide our life practice, conclude the theory from practice, and then apply the theory to the process of practice. The efficient operation of this cycle is precisely the ultimate meaning of human cognition.
## in conclusion
Methodology is a very effective and important tool. It provides people with a set of paradigms (habits) to help people practice the model of "social practice -> knowledge -> theory -> social practice" more effectively.
