The following was spawned at dinner after a day of flying at Dockweiler with Bob Kuczewski on gifted wing from Frank Colver on Dec 2, 2025.
Quiddities: Essences seem more "real" to me than the pile of accidentals.
ChatGPT said:
It makes sense that you’d feel that way. When you focus on essences—those core features that make a thing what it is—you’re pulling away from the flux and noise of the world and toward something that feels stable, intelligible, and durable.
Accidentals shift with circumstance: color, size, posture, mood, location, timing. They’re countless and transient. Essence, by contrast, presents itself as the through-line—what remains when all the changeable layers are peeled back.
This tendency has deep philosophical roots:
• In Aristotelian language, the essence is what grounds a thing’s identity; accidentals explain variation but not “what it is.”
• In medieval scholastic thought, quiddity (the “whatness”) is the object of the intellect. Because intellect grasps what’s universal and stable, essences feel more “real” to the mind than the shifting appearances.
• In phenomenology, some argue that we naturally seek invariant structures in experience; the mind is drawn to what stays the same across variations.
So your intuition lines up with a long tradition: the intellect leans toward the stable center rather than the moving periphery.
What’s interesting is how people differ in this preference. Some think reality is the changing pile of accidentals; others, like you, feel reality shows itself most clearly in the distilled core.
If you want, we can explore how this perspective might shape your approach to objects, people, design work—your hang-glider thinking actually mirrors this: you’re often aiming to understand the essential structural principles beneath the variable materials and configurations.
=============
Quantization of accidentals seems also give more realness to quiddities for me.
ChatGPT said:
That’s a sharp observation. When accidentals get quantized—broken into discrete, countable, limited options—they often lose the sense of depth or “thickness” that continuous variation has. Once they’re chopped into units, they feel more like surface-level toggles than aspects of being.
That shift naturally throws more weight toward quiddity.
Here’s why your intuition makes sense:
1. Quantized accidentals lose their fluidity.
In reality, accidental traits often vary on smooth continua: slight shifts of hue, micro-variations in tone, weight, contour, timing. When we quantize them—by measurement, categorization, or simplification—we flatten them into labeled steps. They become less “alive,” less tied to the being of the thing.
2. Essence doesn’t get quantized as easily.
Essence is qualitative, not stepwise. The more we discretize the accidentals, the more essence appears as the remaining “continuous” or indivisible core. It simply outlasts the breakdown process.
3. Quantization highlights the limits of accidentals.
When you notice that accidentals only rearrange within a finite or structured set, it reinforces the idea that they’re superficial arrangements on top of something more fundamental.
4. Pure quiddity often feels untouched by measurement.
Quantization is a human tool; quiddity feels like something the thing has by its own right. That contrast makes quiddity seem more real.
You can see this play out in several domains:
Physics: Quantizing fields or energy levels isolates the “behavioral possibilities,” which makes the underlying symmetry or structure look more primary.
Biology: Countable traits vary, but the organism’s form and function seem to have deeper unity.
Aesthetics: A painting’s pixel grid is accidental; the composition—its organizing principle—feels essential.
Your mind is picking up on a real philosophical dynamic:
the more we discretize the periphery, the more the center stands out.
===============================================
Exactly—and once you notice that, the whole landscape shifts.
If every accidental quality can be analyzed into constituents that themselves have essences, then the old hierarchy between “essence at the center” and “accidents at the edge” becomes a kind of **nested ontology** rather than a flat split. You’re seeing what medieval thinkers sometimes called *substantial depth*: the idea that anything that shows up as a surface feature ultimately rests on another layer of being with its own core.
A few ways this plays out:
**1. Accidents aren’t pure thinness—they’re expressions of deeper essences.**
A color is an accidental property of a leaf, but the color itself arises from molecular structures, pigment configurations, and photon interactions, each with their own quiddity. So the “accidental” is an interface, not a free-floating superficiality.
**2. This creates a cascade of essences.**
Essence shows up at every level:
* the leaf has an essence,
* its chlorophyll has an essence,
* the porphyrin ring that gives chlorophyll its absorption spectrum has an essence,
* the atoms making that ring have essences,
* the particles composing atoms… and so on.
In that view, the accidental-quality field isn’t accidental *all the way down*.
**3. It’s essence that lets an accidental be what it is in the first place.**
A shape, color, or texture hangs together only because deeper structures hold together in determinate ways. Without those structured essences, the accident would collapse into randomness.
**4. So the distinction becomes relational, not absolute.**
An accident is “accidental to *something else*,” but that same accident can be essential in its own domain.
The redness of a brick is accidental to the brick, but essential to the nature of the iron oxide molecules that create that redness.
**5. This makes the world feel more articulated than chaotic.**
Instead of seeing accidents as arbitrary overlays, you see them as the place where essences meet and express one another.
This is a very elegant metaphysical stance: **the accidental is never mere decoration; it’s a doorway into deeper quiddities.
=====================================
>>> And so I look into UPHGs from these lights.
That’s a fitting way to approach your UPHG and TPHG work. Looking at the project
through the lens of quiddities and accidentals actually clarifies the engineering
choices you make.
1. The UPHG has an essence—its organizing principle
At the core, the craft has a quiddity:
a human-portable, ultra-packable hang glider that unfolds into a stable,
controllable aerodynamic structure.
Everything else—materials, segment counts, joint geometries, sock styles,
hinge designs—is accidental relative to that essence.
2. Each accidental design choice has its own essence
A Joe Cup, a telescoped spar segment, a compression stick with dual stiffness—
each is “accidental” to the glider as a whole, but has its own quiddity:
• Coupler essence: limit insertion, stabilize the joint, protect tube ends,
allow nesting, take rigging load.
• Spar segment essence: carry compression, nest efficiently, maintain
stiffness/weight balance.
• Sock essence: lock geometry, distribute pressure, allow tolerance,
preserve collapsibility.
3. Quantization of accidentals clarifies the underlying essence
The design quantizes accidentals:
• fixed 4 ft spar lengths
• discrete segment types (A…H)
• fixed coupler positions
• nested/un-nested states
• loose/loaded rigging states
These discrete forms make the UPHG’s essence stand out more sharply.
The more configurational options are discretized, the more the aerodynamic
and structural principles show through.
4. The UPHG’s essence unifies the nested subsystem essences
Every accidental in the glider has its own quiddity. The designer’s task is
to harmonize these across levels:
• tube/segment essence
• glider structural essence
• assembly/disassembly essence
• nesting essence
• aerodynamic essence
Alignment among these levels makes the whole glider feel “right.”
5. This view explains the preference for elegant structural solutions
Thinking in terms of essences encourages:
• clean geometry
• natural load paths
• multi-functional parts with intrinsic structural unity
• minimal ad-hoc complexity
The goal becomes: discover the essence of the structure, then let every
accidental express and support it.
