Wie nutzt man das Quadrat der Tugend?

The Square—often referred to as an emblem of virtue—serves both as a physical instrument in the lodge and as a moral guide for self-examination 12. In operative stonemasonry, the try-square is used to test whether stones are cut at the correct ninety-degree angle; if a stone fits the square, it is ready for the builder's use 2. Speculatively, it is applied to test and adjust a Mason's actions, words, and moral conduct 12.

Within the lodge, the symbol is employed in several specific ways:

First, it sits upon the altar, combined with the Compasses to teach the Mason to square his actions and keep them within due bounds, forming a recognized token of duty and brotherhood 12. It is also worn as the immovable jewel of the Master of the Lodge, symbolizing that all instruction and leadership in the East must be square 2.

Second, it governs physical movement during ritual circumambulation, where members walk around the lodge turning corners on the square, visibly combining the square and the circle 12.

Third, it serves as a principle of conduct in the phrase "part upon the square" 1. While members meet upon the level without distinction of class or rank, parting upon the square requires that they leave the lodge acting uprightly, carrying away no hypocritical feeling or resentment 1.

Beyond ritual mechanics, the Square is described as an internal "try square of conscience" for daily life, by which a Mason continuously measures his personal morality, fair dealing, and integrity 2.
