Is "square an compass" or "square and compasses"?
The correct and universally recognized term is "Square and Compasses." This iconic symbol of Freemasonry represents the tools of the operative stonemason, elevated to a symbolic level.
The Square symbolizes morality, virtue, and the importance of acting with integrity and honesty in all our dealings. It reminds us to "square our actions by the square of virtue."
The Compasses symbolize the boundaries of our desires and passions, encouraging us to live within proper limits and to be mindful of our conduct towards others. As Albert Pike states in Morals and Dogma, the compasses "teach us to circumscribe our desires and keep our passions within due bounds."
Together, the Square and Compasses are a powerful visual representation of the moral and ethical principles that Freemasonry seeks to instill in its members.
