What do you mean that human nature is not an abstract thing inherent in a single person?

This is a sociological point of view, pointing out that human nature is not just an abstract thing inherent in a single person, but is influenced and restricted by social relations. This means that human nature is not only an individual's internal personality and personality characteristics, but also determined by social environment, culture, history and social relations. In other words, people's behavior, ideas and values are all influenced and restricted by social relations, which include not only the intimate relationship between individuals and their families, friends and colleagues, but also the relationship between individuals and social institutions such as government, education and economy. Therefore, human nature should be regarded as the sum of all social relations. This view emphasizes the importance of social relations to individuals, but also reminds people of the interaction between individuals and society, as well as the interaction between personal behavior and social environment.
