Which virtue is highlighted by the Masonic symbol of the plumb?

The Masonic symbol of the plumb is primarily associated with integrity and uprightness. The plumb is a tool used in construction to ensure that structures are vertical and true, symbolizing the importance of being straight and honest in one's actions and dealings. This reflects the moral and ethical standard that Masons strive to uphold in their lives.

In Masonic teachings, to be "upright" is to adhere to principles of integrity, ensuring that one's conduct is aligned with the virtues of honesty and moral rectitude. The plumb serves as a reminder for Masons to assess their own actions and character, aiming to be true in all aspects of life. This alignment with integrity and uprightness is essential within the Masonic philosophy, highlighting the importance of ethical behavior and accountability.

While other virtues like wealth, discipline, and compassion are valuable, they do not capture the specific moral lesson embodied by the plumb as clearly as integrity and uprightness do in the context of Masonry.
