When viewed together, these symbols reveal a profound geometry of human existence. The Level, the Plumb, and the Square are not merely tools of construction. They are symbols of how human beings encounter reality, conduct themselves during life, and ultimately leave behind the record of their character.
The Fellow Craft is taught that the Level is used to prove horizontals, the Plumb to prove perpendiculars, and the Square to prove right angles. Operatively, these are practical tools. Speculatively, they describe three dimensions of existence. The horizontal represents the plane upon which human life unfolds. The vertical represents the relationship between humanity and transcendent standards. The right angle represents the proper ordering of relationships among human beings.
The lecture further teaches that all men travel upon the Level of Time toward “that undiscovered country from whose bourne no traveler returns.” Borrowed from Shakespeare’s Hamlet, the phrase reminds the candidate that every person, regardless of station, travels the same temporal road. Kings and laborers, scholars and tradesmen, rich and poor alike move through the same succession of hours, days, and years. Mortality becomes the great equalizer.
Yet the Level appears to teach something deeper than equality. It teaches perspective.
A horizontal line neither rises above nor descends below another point on the same plane. It extends outward. It connects. It establishes relationship. To meet another person upon the Level is to encounter him without the distortions of status, wealth, power, reputation, or prejudice. It is to meet the person before the title.
This interpretation finds remarkable parallels in traditions separated by geography, language, and centuries.
The Stoic emperor Marcus Aurelius repeatedly reminded himself that death eventually reduces all distinctions. He observed that Alexander the Great and his mule driver ultimately shared the same fate (Marcus Aurelius, trans. 2002). The Stoics believed that wisdom begins when one ceases to be governed by external distinctions and instead focuses on virtue, reason, and character (Hadot, 2001). In this sense, the Level frees the individual from the illusions created by social comparison.
A similar principle appears in Taoism. Lao Tzu warns that many human distinctions arise from the mind’s tendency to divide and categorize reality. High and low, success and failure, gain and loss exist in relationship to one another (Lao Tzu, trans. 1963). The sage learns to perceive reality without becoming attached to these distinctions. Such a person stands metaphorically upon the Level.
The I Ching presents a comparable ideal in the figure of the superior man, or junzi. The superior man is not superior because he dominates others. He is superior because he governs himself, remains centered amid changing circumstances, and perceives situations clearly (Wilhelm & Baynes, 1967). The superior man occupies the middle ground between reaction and passivity, between pride and despair. Like the Mason traveling upon the Level of Time, he learns to move through life without being consumed by its fluctuations.
Buddhist philosophy reaches a similar conclusion through a different route. The Buddha taught that attachment to transient things produces suffering (Rahula, 1974). Many of these attachments concern identity, status, prestige, and comparison. By recognizing the impermanence of such distinctions, the individual develops equanimity. The result is not indifference but clarity. The Buddhist no longer sees himself as above or below others. He simply sees.
The Hindu tradition expresses a related insight in the Bhagavad Gita. Krishna teaches that the wise person sees with equal vision the learned, the humble, the powerful, and the lowly (Prabhavananda & Isherwood, 1944). The lesson does not deny differences among individuals. Rather, it teaches that beneath those differences lies a deeper reality. The Level similarly invites the Mason to encounter the person beneath the circumstance.
Jewish mysticism contributes another dimension. Kabbalistic thought often describes reality through the image of the Tree of Life, a structure linking heaven and earth through a series of emanations (Scholem, 1974). Humanity occupies a middle position between the material and the divine. The spiritual task is not escape from the world but alignment with higher principles while living within it. This mirrors the relationship between the Level and the Plumb. The Level represents the plane of ordinary existence; the Plumb introduces the vertical dimension of transcendence.
The Plumb acquires special significance through the prophet Amos. In one of Scripture’s most memorable visions, God stands with a plumbline in His hand and declares, “Behold, I will set a plumbline in the midst of my people Israel” (Amos 7:8, King James Version). Here the plumbline becomes a divine instrument of measurement. It establishes an objective standard against which conduct is evaluated.
The symbolism is striking. Humanity travels horizontally through time, but life is measured vertically.
The Plumb asks whether a life is upright. The Level reminds us that all travelers share the same road.
The relationship between these symbols becomes even more compelling when considered alongside the closing questions of the lodge.
The Master asks:
“How should Masons meet?”
The Senior Warden replies:
“Upon the Level.”
The Master then asks:
“How should Masons act?”
The Junior Warden responds:
“By the Plumb.”
Finally, the Master declares:
“And part upon the Square.”
The sequence is often interpreted as a summary of Masonic conduct. Yet it can also be understood as a symbolic summary of human existence.
We enter life upon the Level.
We live under the Plumb.
We depart upon the Square.
The Square, unlike the Plumb, concerns relationships. It proves right angles. It ensures that parts fit together properly. Symbolically, it governs justice, fairness, and integrity. A life lived by the Plumb is measured against truth. A life that parts upon the Square leaves behind relationships that are honorable, obligations fulfilled, and duties discharged.
This sequence gains additional depth when viewed through the Fellow Craft lecture’s discussion of geometry itself. The candidate learns that a point extended becomes a line, a line extended becomes a superficies, and a superficies extended becomes a solid.
The symbolism parallels the development of human life.
A point represents potential.
A line represents a journey.
A superficies represents the shared plane upon which lives intersect.
A solid represents the completed structure.
Human existence unfolds in exactly this manner. The infant begins as potential. Life extends into a journey. Relationships create a shared social plane. Character transforms experience into substance. The completed life becomes a finished structure.
The Level occupies a central position in this process. It is the plane upon which development occurs. Without the Level there is no field of action, no place of encounter, no common ground upon which human beings may learn, labor, and grow.
This may explain why the symbolism of the Level resonates so strongly across cultures and philosophies. Stoicism, Taoism, Buddhism, Hinduism, Christianity, Kabbalah, and the I Ching all identify a common obstacle to wisdom: the distortions created by ego, status, pride, attachment, and comparison. Each tradition proposes a different solution, yet all arrive at a similar conclusion. Human flourishing depends upon seeing reality clearly.
The Level teaches precisely this lesson.
It does not merely proclaim equality. It cultivates perception.
To meet another person upon the Level is to see beyond the temporary distinctions that often dominate human judgment. It is to recognize a fellow traveler moving through the same stream of time, facing the same uncertainties, and approaching the same horizon.
The greatest advantage of living upon the Level is therefore not that it makes a man equal. It is that it frees him from illusion.
A man who sees clearly learns more readily, judges more fairly, acts more wisely, and responds more effectively to the changing circumstances of life. Such a man becomes capable of living by the Plumb and departing upon the Square.
In this sense, the Level may be the hidden foundation of the entire system. It is the plane upon which life is lived, character is tested, and wisdom is acquired. It is not merely a symbol of equality. It is a discipline of perception, teaching the Mason to see himself, his fellow man, and reality itself as they truly are.
