① Educatability of people: that is, people have the natural quality and potential ability to receive education. The reason why people can be educated mainly lies in their plasticity, which is manifested in the fact that their sensory organs and psychological functions are "not specific". It is this "non-concreteness" that opens up infinite possibilities for people to develop through education. Man's "unspecific" enables him to adapt to the environment, and his right to use is not limited by the specific living environment, so that he does not need to change his biological nature and biological structure in order to survive, but only needs to change his external lifestyle and living environment. People's "unspecific" is the premise of people's plasticity, and plasticity is the premise of people's educatability. The revelation of modern scientific research on human potential shows the broad prospects of human education. Of course, people's educational ability is limited. People's educationability is different from genetic determinism (or biological predeformation theory) and educational omnipotence theory.

② People's demand for education: People are not only educationable, but also need education, because people are "social animals" and individuals can only survive in society. Individuals need education to gain survival ability, but also need education to become a person recognized by society. People have very rich potential, and the development of human potential can not be separated from education. This proves the necessity of education from another angle. Not only human beings need education, but also human society needs education to maintain its continuation and development. The fundamental difference between human society and animal kingdom is that human beings have culture, which is the confirmation and representation of human essential strength and the extension of human psychosomatic ability. Education makes it possible to preserve, continue, develop and enrich culture.
