"Let not a man do what his sense of right bids him not to do, nor desire what it forbids him to desire. This is sufficient. The skillful artist will not alter his measures for the sake of a stupid workman"

This quote by Mencius recommends individuals to follow their sense of right and wrong and prevent actions that break their values. It also recommends that one must not prefer things that are prohibited by their conscience. The comparison of an experienced artist not modifying their measures for a less qualified employee highlights the importance of keeping one's requirements and principles.
