We have a collection of 2 Teacher quotes from Xun Zi
"When people lack teachers, their tendencies are not corrected; when they do not have ritual and moral principles, then their lawlessness is not controlled." (ID 2512)
"Therefore, a person should first be changed by a teacher's instructions, and guided by principles of ritual. Only then can he observe the rules of courtesy and humility, obey the conventions and rules of society, and achieve order." (ID 2665)
