《墨子·71章 杂守》
世上有谗间之人，有好利之人，有恶人有善人，有具有专长的人，有谋士，有勇士，有巧士，有使士，有能容人者，有不能容人者，有善于待人的人，有善于守门的人，守城主将务必要考察他们为何具备那种品性或特长，名符其实的便接纳使用。
有谗人，有利人，有恶人，有善人，有长人，有谋士，有勇士，有巧士，有使士，有内人者，外人者，有善人者，有善门人者，守必察其所以然者，应名乃内之。
The world has those who slander others, those who are greedy, those who are evil, those who are good, those who have expertise, those who are advisors, those who are warriors, those who are skillful, those who are envoys, those who can tolerate others, and those who cannot tolerate others; those who are good at interacting with people and those who are good at guarding the gates; the defender of a city must examine the reasons for these personalities or characteristics and accept and use those who live up to their reputation.
