The process of social development is not influenced by human subjective will. Marx's historical materialism not only examines society dialectically, but also regards social development as a natural historical process, revealing the objective regularity of social life. The so-called "natural historical process" means that the development of society, like nature, is an objective process that conforms to the law. Although a fundamental point that distinguishes society from nature is that society is not developed by itself, it must be realized through the practical activities of conscious and intentional people. But the development of society is independent of human will. This is because people's will is not subjective and spontaneous, but has its objective roots; Moreover, people's will in social development is not single, but a kind of resultant force and a general average, which is formed by the interaction of countless wills rooted in different objective conditions. Therefore, although people's actions have conscious intentions and expected purposes, the results of their actions are often unexpected. The development of society is not the product of a single will, but the result of the interaction of various forces under the control of general economic movements that obey the objective laws within society. Revealing the material source of human will and ideological motivation is the only correct way to discover the objective law of social development. Marx's method of studying social life is: dividing the economic field from all fields of social life, dividing the relations of production from all social relations, and taking the relations of production as the basic primitive relations that determine the rest of social relations, which comes down to the height of productivity, thus indicating productivity.
It is the foundation of the whole history, revealing the objective laws of social development such as the relations of production must adapt to the productive forces and the superstructure must adapt to the development requirements of the economic base. Historical materialism's scientific assertion that social development is a natural historical process provides an objective basis for the proletariat and revolutionary people to understand and transform the world.
