Meaning: The quote "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." comes from Mencius, a renowned Chinese philosopher who lived during the Warring States period (5th to 3rd century BCE). Mencius, also known as Mengzi, is considered one of the most important Confucian philosophers, and his teachings have had a profound impact on Chinese thought and culture.

In this quote, Mencius emphasizes the importance of following one's sense of right and wrong, and not being swayed by external influences or pressures. He suggests that individuals should adhere to their internal moral compass and not be tempted to act contrary to their conscience. The reference to the "skillful artist" and the "stupid workman" can be interpreted as an analogy for the importance of maintaining one's principles and not compromising them for the sake of others who may not understand or appreciate the value of those principles.

Mencius' emphasis on the importance of moral integrity and personal conviction reflects the central tenets of Confucianism, which places great emphasis on ethical behavior, social harmony, and the cultivation of virtuous character. According to Mencius, human nature is inherently good, and individuals have the capacity to cultivate and develop their moral faculties through self-reflection, ethical practice, and virtuous conduct.

The concept of following one's sense of right and not desiring what it forbids aligns with the Confucian idea of ren, often translated as "benevolence" or "humaneness." Ren is considered a fundamental virtue in Confucian ethics, and it involves cultivating a sense of empathy, compassion, and moral sensitivity towards others. By adhering to one's sense of right and wrong, individuals can cultivate their sense of ren and contribute to the well-being of society.

Furthermore, Mencius' emphasis on staying true to one's principles and not altering one's measures for the sake of others reflects the Confucian ideal of integrity and moral rectitude. Confucianism places a strong emphasis on ethical leadership and the importance of virtuous rulers who govern with wisdom, compassion, and a commitment to the well-being of the people. Mencius' teachings often focused on the role of moral leaders in creating a just and harmonious society, and his emphasis on individual moral integrity aligns with the broader Confucian vision of ethical governance and social harmony.

In summary, Mencius' quote underscores the importance of moral integrity, personal conviction, and adherence to one's sense of right and wrong. His teachings emphasize the cultivation of virtuous character, ethical conduct, and the pursuit of social harmony. By following one's internal moral compass and not being swayed by external pressures, individuals can contribute to creating a more just and compassionate society, in line with the principles of Confucianism.
