This view accords with the characteristics of the initiative and internal factors of the internal law theory. The endogenous theory of pedagogy is a philosophical theory, which holds that people's behavior and character are determined by internal factors, namely, people's spirit, thought, will and morality. And is not controlled by external factors. The theory that education is the turn of the soul emphasizes that individual's intrinsic motivation and desire are the key to realize the educational goal, which means that when individuals are interested in and independent of the learning content and process, they actively study independently, rather than being controlled by the external environment. This view accords with the characteristics of the initiative and internal factors of the theory of internal laws, so education, that is, the turning of the soul, is endogenous.
