Qualitative Geometry
The Ruler & Compass

The Ruler: The tool of the Finite. It represents "Manifestation," "Duality," and "Matter." It connects two points in the shortest possible distance, representing the "Law" and "Logic." The ray of light follows essentially a ruled path through empty 3D Euclidean space, but can curve if the "paper" of four-dimensional spacetime is warped by mass.
The Compass: The tool of the Infinite. It represents the "Unmanifested," the "One," and the "Spirit." It has a fixed center (The Self/Source) and a moving periphery (The World). The star can be "circumscribed" only with a compass. The star's surface encompasses its fusion reaction which powers it and gravity warping four-dimensional spacetime gives it a hyper-spherical form. The circle is just the 2D shadow of the higher-dimensional mathematical reality.

Beyond the Ruler & Compass
excerpt from The Unlikely Cartographer (pages 32-33)
"This wasn't just about
appearances or relationships; it was an outward manifestation of an internal
shift, an attempt to align my external self with the expanding horizons of my
inner world. Studying at Berkeley, a campus large enough to contain multitudes,
it became strikingly clear that the cultures of engineering and architecture
occupied almost entirely separate psychological and even physical territories
on campus. Engineering students, clustered in their labs and lecture halls on the
north side of campus, often viewed the world through a lens of empirical data,
logical systems, and quantifiable results. Architecture students, inhabiting
the design studios and art history lecture rooms on the south side, tended to
engage with reality through aesthetic sensibility, intuitive leaps, and the
interpretation of cultural meaning. They were like two distinct species,
speaking different languages, valuing different forms of knowledge, largely
invisible to one another despite their physical proximity.
This observation led me to reflect on the notion, if somewhat simplistic for the sake of argument, of "left-brain" versus "right-brain" dominance. It seemed that most people, perhaps through early aptitude, educational tracking, or cultural reinforcement, tended to develop and prioritize one mode of thinking over the other. The left brain, with its penchant for analysis, sequence, language, and logic, felt like the natural home of the engineer. The right brain, with its capacity for holistic perception, spatial reasoning, intuition, and synthesis, seemed to be the domain of the artist and designer."
North Campus: The Engineer
Empirical Data | Logical Systems | Quantifiable Results
Quantitative Geometry: The geometry of the engineer. It asks: How big is it? How much does it weigh? Will it stand up? (The world of forces, dimensions and measurement).
In the "Standard Worldview," geometry is an inert but useful tool to anyone who wants to design and engineer stuff in the world.
The Circle: Is x2+y2=r2 or "a plane figure contained by one line such that all the straight lines falling upon it from one point among those lying within the figure are equal to one another," according to Euclid.
Off Campus: Encountering the Invisible Territory
At Berkeley, I saw these two distinct hominid species speaking different languages, largely invisible to one another despite their physical proximity. Most people are tracked into one territory or the other, weighted heavily on their one dominant side of the brain.
My work is in part my attempt to align the outer with the inner, the object with the subject, the society with the culture, the agency with the communion, the anima with the animus—to build the necessary bridge, the Corpus Callosum, between the North and South campus of the mind.
South Campus: The Artist or Architect
Aesthetic Sensibility | Intuitive Leaps | Cultural Meaning
Qualitative Geometry: The geometry of the mystic and artist. It asks: What does it mean? How does it feel? What does it reveal about the nature of reality? (The world of meaning).
In our "Alternative Worldview," geometry is the living language of universal mind, which we all find intelligible, at least to some degree.
The Circle: Is the quality of Unity and Wholeness. It defines a boundary having an inside and and outside. What is me, and what is not me?

So What?
The sensitive students among us may start to feel like they almost remember something deep within the qualia of geometry. It happens when we see Truth in the geometry's perfection, palpably feel its Beauty, and bask in its undeniable Goodness. It is then that we are holding up a mirror to who we truly are, transcendental beings of pure consciousness. This is a BIG DEAL. It changes you. I can tell you, but you need to experience it yourself to really get it.
If you are an Artist
Ground your intuition in universal law. Learn the 'Code' that gives your vision unassailable structure.
If you are an Engineer
Discover the poetry in your precision. Learn why the numbers you use every day are actually a gateway to meaning.
I’m not an Artist or an Engineer—is this for me?
Absolutely. The "North and South Campus" is a metaphor for the two halves of your own mind. Most of us live "off-balance," favoring either cold logic or ungrounded intuition. Qualitative Geometry acts like the "Corpus Callosum" from the visible world of atoms to the invisible soul of your first-person experience—it is the practice of integrating your analytical mind with your spiritual heart. If you’ve ever felt that the world is more than just "empirical data" but struggled to find a logical way to explain that feeling, this work might be the bridge you’ve been looking for.

- Geometry is number in space
- Music is number in time
The Qualitative Path is easy, just open your eyes and be guided to appreciate beauty. The Quantitative Path is complex, taking years to master the skills and the knowledge. The Mathematical Path is hard, you must prove it to be true with unassailable logic. All are the same geometry. What changes is you. Why not open up to a fuller universe that includes left, right, and center? They are all partial truth, partial beauty, partial bliss. When we integrate them we sense the ineffable exquistite perfection of the mathematical universe, finely-tuned to support each being's smile, laugh, their "Aha!" Moments.
Geometry is the only language that exists simultaneously in the engineering lab and the cathedral. This page invites you to stop choosing between 'how it works' and 'what it means' and start seeing the universe as a unified, intelligible masterpiece.
Engage in a Sacred Anachronism: DRAW GEOMETRY.
Stop consuming the digital world and start constructing an analog one. By returning to the primary language of
shape and proportion, you bypass the noise of the standard worldview and rediscover the qualia
of your own consciousness.
