Which tool symbolizes moral rectitude in Freemasonry?

The square is a significant symbol within Freemasonry that represents moral rectitude, integrity, and fairness in one's dealings with others. This tool is used in masonry to ensure that angles are right, which metaphorically parallels the idea of ensuring that one's actions align with ethical standards. Freemasons are encouraged to live by the principles of truthfulness and honesty, and the square serves as a reminder to measure their actions and decisions by this moral standard.

In Freemasonry, the other tools symbolize different virtues; for example, the plumb is often associated with uprightness and honesty, while the level symbolizes equality among men. The gavel, on the other hand, is used to call attention and maintain order, focusing more on the governing aspects of the lodge rather than personal morality. Thus, while all the tools have their significance, the square uniquely embodies the concept of moral rectitude in a way that is central to Freemasonic teachings.
