Secondly, the animal kingdom has no advanced language and symbol system, and their thinking is not developed enough. All animals only stay at the "individual" level. Humans are "symbolic animals" with advanced language symbol system. Through this symbol system, people can classify experiences, make people have conscious class consciousness, consciously safeguard class development, and make their own contributions to common interests under the condition of sharing resources.
Furthermore, animal education basically ends with the maturity of physiology. And human education will never stop at the maturity of the body.
To sum up, education is a unique activity of human society, and sociality is a human educational activity, which is essentially different from the so-called "educational" activities of animals.
