What is the sentence that best reflects that Confucius teaching does not distinguish between students and Confucius?

Confucius' view that education has no class comes from his analysis of human nature.

He said that "people are similar in sex, but far from each other in knowledge" (The Analects of Confucius, Yang Huo). Confucius believed that human nature is similar, but the differences between people are far from each other because of differences in habits and education. Therefore, the role of education and environment on people far exceeds heredity. He believes that although people have good qualities, they can't become talents spontaneously. Only through study and education can they improve and progress day by day.

A conversation between Confucius and his disciple Luz profoundly clarified this view. Lutz once asked, "Is learning also beneficial?" "Nanshan has bamboo. If you rub them straight, cut them and pass them on to the skin of rhinoceros, why learn? " Confucius said, "Is it beneficial to have feathers?" Lutz said sincerely: "Respect teaching!" (Liu Xiang: "Talking about Yuan Jianben").

I hope I can help you!
