Cosmos — Is reality, at bottom, made of things, numbers, relations, or process?
What is the universe made of at the deepest level? Material particles, or something more abstract? Today's four thinkers give four radical answers: Pythagoras says all things are number, the skeleton of the cosmos is mathematics; the Yijing says the Supreme Ultimate gives birth to the two modes, the cosmos is the layered generation of yin and yang; Huayan Buddhism says one is all, every speck of dust mirrors the entire dharma-realm; Whitehead says reality is not thing but process. As physics arrives at strings and fields and AI encodes the world into vectors, these ancient cosmologies are being revived in startling ways.
Pythagoras
West · Ancient Greece / Pythagoreans
Philolaus, fragment B4; Aristotle, Metaphysics A.5 · c. 6th century BCE
CORE THESIS · PRIMARY TEXT
καὶ πάντα μὰν τὰ γιγνωσκόμενα ἀριθμὸν ἔχοντι· οὐ γὰρ οἷόν τε οὐδὲν οὔτε νοηθῆμεν οὔτε γνωσθῆμεν ἄνευ τούτω. — All things that can be known have number; for without number nothing could be thought or known. — Philolaus, fragment B4
Thesis: number is not a tool for counting things but the very principle (archē) of all things. The cosmos is knowable precisely because it is itself built out of number and proportion.
CONTEXT & KEY INSIGHT
At the threshold where Greece turned from myth to a rational cosmology, the Pythagoreans made a stunning discovery: harmonious tones correspond to simple whole-number ratios (string-length 2:1 is the octave, 3:2 the fifth). The most ethereal of sensory phenomena turned out to be precisely fixed by integers, and they extrapolated boldly: the whole cosmos (kosmos, literally "order") is an expression of number and proportion — even the motions of the heavens a "music of the spheres." This was humanity's first claim that the floor of reality is not matter but abstract mathematical structure.
CROSS-DISCIPLINARY
This is no vague "the ancients knew math too" — Pythagoras's intuition is the core creed of modern physics. Galileo: "the book of nature is written in the language of mathematics"; Wigner marveled at "the unreasonable effectiveness of mathematics"; today string theory reduces particles to vibrational modes (almost literally a "music of the spheres"), and Tegmark goes further, claiming "the universe just is a mathematical structure" — physics keeps redeeming Philolaus's assertion.
CONTEMPORARY RELEVANCE
For BigCat: Pythagoras is the ancestor of "everything can be modeled." Deep learning encodes images, language, and sound alike into high-dimensional vectors — the extreme contemporary version of "all things are number." But the school was shaken by the irrational √2: use quantitative modeling for leverage, yet always remember which values (meaning, ethics, a child's laughter) refuse to be compressed into a vector.
ESSENCE · QUESTION
Irreplaceable insight: the floor of reality may not be matter but mathematical structure — knowability itself is the order of the cosmos.

Yijing · The Supreme Ultimate Begets the Two Modes
East · China / Yijing Studies
Book of Changes, "Great Treatise" (Xici I), ch. 11 · compiled Western Zhou–Warring States
CORE THESIS · PRIMARY TEXT
In change there is the Supreme Ultimate (taiji); it gives birth to the two modes (yin and yang); the two modes give birth to the four images; the four images give birth to the eight trigrams; the eight trigrams determine fortune and misfortune; and fortune and misfortune give birth to the great enterprise. — Book of Changes, "Great Treatise" I
Thesis: the cosmos begins from the undivided "Supreme Ultimate," and through the ceaseless splitting-in-two of yin and yang (the two modes) generates the myriad phenomena layer by layer. The world is not a finished product but a continuously differentiating, self-unfolding process of generation.
CONTEXT & KEY INSIGHT
The "Great Treatise" is the philosophical charter composed in the Warring States period for the hexagrams of the Yijing; its cosmology runs in a single line: taiji (1) → two modes (yin/yang, 2) → four images (4) → eight trigrams (8) — a precise binary doubling series. Two key points: first, the complexity of all things arises from the recursive iteration of one minimal rule (yin–yang bipartition); second, the root dynamic of the cosmos is the mutual transformation of opposites — "one yin and one yang, that is the Dao." This is a dynamic, processual cosmology, far from the West's static-substance tradition.
CROSS-DISCIPLINARY
After Leibniz invented binary, he was astonished to find the "Earlier Heaven" trigram arrangement was exactly the binary sequence 000–111, and said the Yijing had "anticipated" his arithmetic — a famous real encounter in intellectual history. The deeper echo is in complexity science: cellular automata prove that minimal local rules, through recursive iteration, can emerge into endless complexity — precisely the mathematical core of "the Supreme Ultimate begets the two modes."
CONTEMPORARY RELEVANCE
For BigCat: "taiji begets the two modes" is an ancient blueprint for "generating complex systems from simple rules," deeply resonant for an architect: the most robust systems don't pile up special cases but rest on a set of recursively composable minimal primitives (like Unix pipes). The same in parenting — rather than legislating every detail, give a few self-propagating root principles. The leverage of the AI age lies in finding that minimal generative kernel.
ESSENCE · QUESTION
Irreplaceable insight: infinite complexity can be generated from the recursive iteration of one minimal rule — the Dao is in the generating, not the finished product.
A complex system you maintain (product, team, habit) — can you trace it back to its original "two-modes" rule? Does it still hold?
Huayan School · One is All
East · China / Mahāyāna Huayan Buddhism
Fazang, Treatise on the Golden Lion & Commentary on the Avataṃsaka; Avataṃsaka Sūtra · Tang dynasty (7th c.)
CORE THESIS · PRIMARY TEXT
As when a jeweled net covers the palace of Indra: within a single bright pearl all images appear; and so it is with every pearl, each reflecting all the others, reflections within reflections, layer upon layer, without end. — Fazang, explaining "Indra's Net" One is all, and all is one.
Thesis: in the dharma-realm every thing mirrors all other things, like the jeweled net of Indra's palace where each pearl reflects every pearl, reflections within reflections, endlessly. The part is the whole, the whole is the part: the unobstructed mutual interpenetration of all phenomena.
CONTEXT & KEY INSIGHT
The Huayan school founded its teaching on the Avataṃsaka Sūtra; Fazang once expounded it to Empress Wu Zetian using the palace's golden lion as a metaphor, building the grandest cosmic vision in Chinese Buddhism. Its core is "dharma-realm dependent origination": all phenomena depend on and contain one another, and nothing can exist independently. "Indra's Net" is its signature image — one is all, all is one. This is relational ontology pushed to the limit of "dependent origination": the basic unit of reality is not an isolated "thing."
CROSS-DISCIPLINARY
The net's "one pearl mirrors the whole net" is strikingly isomorphic with physics's holographic principle: the entire information of a region can be encoded on its boundary surface, the part containing the whole. Quantum entanglement gives "unobstructed interpenetration" a physical counterpart — entangled particles, however far apart, are correlated as one indivisible whole.
CONTEMPORARY RELEVANCE
For BigCat: Indra's Net is the deepest metaphor for "systems thinking": each of your decisions ripples through the net, mirrored across team, family, market. The truth of the "AI super-individual" is not lonely peak but becoming a pearl in the net with stronger reflective power — the richer your connections and the clearer your reflecting, the greater the individual's energy. Drop the illusion of "solo achievement," and a whole-system perspective opens instead.
ESSENCE · QUESTION
Irreplaceable insight: nothing is isolated — each part mirrors the whole; the floor of reality is endless mutual containment.
A recent "personal achievement" of yours — if you honestly unpack the web of relations it depended on, how much truly belongs to you alone?
Alfred North Whitehead
West · Britain–USA / Process Philosophy
Process and Reality · 1929
CORE THESIS · PRIMARY TEXT
how an actual entity becomes constitutes what that actual entity is… Its 'being' is constituted by its 'becoming.' This is the 'principle of process.' — Process and Reality
Thesis: the ultimate units of the cosmos are not enduring, unchanging "substances" but "actual occasions" that arise and perish in an instant. To be is to become; it is not that things exist first and then change — change (process) itself is what is real.
CONTEXT & KEY INSIGHT
Whitehead was first a mathematician (co-author with Russell of Principia Mathematica). Late in life, facing the upheaval in worldview brought by relativity and quantum mechanics, he proposed process philosophy to correct the West's "substance bias" since Aristotle — the "fallacy of misplaced concreteness" that sees the world as a heap of static objects with fixed properties. He argued: reality is made of countless momentary "events of becoming," each "prehending" the past and contributing to the future. The cosmos is a creative stream of process.
CROSS-DISCIPLINARY
Process philosophy resonates deeply with quantum field theory: in field theory a "particle" is not a little ball but an excitation event of the field — the basic unit of reality really is "event," not "thing." Rovelli's relational quantum mechanics goes further, holding that physical quantities are determined only in interaction, almost isomorphic with "actual occasions"; and "to be is to become" also echoes the Buddhist "all conditioned things are impermanent."
CONTEMPORARY RELEVANCE
For BigCat: process philosophy gives "the self" a liberating redefinition: you are not a fixed "I" but a stream of becoming made of choices and occasions. This shares a root with the growth mindset — don't ask "what kind of person am I," ask "what am I becoming right now." See life, career, and parenting as process rather than finished product, and anxiety eases: nothing needs to be "completed" once and for all.
ESSENCE · QUESTION
Irreplaceable insight: the floor of reality is process, not substance — to be is to become; all things are events in the happening.
If "you" were not a noun but a verb (an ongoing process of becoming), what are you becoming today?
Four cosmologies, four keys: Pythagoras says the floor is number, the Yijing says it is the generation of yin and yang, Huayan says it is mutually containing relation, Whitehead says it is process. All four resist the same commonsense: the cosmos is not a heap of isolated, static, ready-made "things." In an age when AI is rewriting the world as a network of relations, this may be exactly the lesson most due for an update.
Going Deeper
Pythagoras says "all is number," Whitehead says "all is process" — can static number and dynamic process be reconciled?
They seem opposed but are complementary. Mathematical structure can itself be dynamic — differential equations and dynamical systems are precisely "the mathematics of process." Whitehead, as a mathematician, did not deny mathematics; he opposed only mistaking mathematical objects for static substances. Perhaps the floor is both process and obedient to mathematically describable patterns: number is the grammar of process, process the life of number.
The Yijing's "taiji begets the two modes" and Huayan's "one is all" — both Eastern, how do their cosmic pictures fundamentally differ?
The Yijing is "generationism" — stressing unfolding in time, one begets two, two begets four, a vertical, diachronic chain of derivation; Huayan is "containmentism" — stressing the horizontal mutual identity at any instant, where each thing here-and-now contains all. One answers "how the cosmos is generated," the other "how all things co-exist." Yet the two can be sutured: vertical generation × horizontal containment makes a complete picture.
If Huayan's "one is all" is true, are the holographic principle and quantum entanglement its physical proof?
Be cautious — structural isomorphism is not causal proof. The holographic principle and entanglement do show that "part encodes whole" and "non-local correlation" are physically real, strikingly like the image of Indra's Net. But Huayan is a contemplative insight about mind and the dharma-realm, while physics is measurable quantitative law; the levels of explanation differ. Seeing them as "echoes of one deep structure in different languages" is illuminating, but saying physics "proves" Buddhism overreaches.
For someone aiming to be an "AI super-individual," what does each of these cosmologies mean in practice?
Pythagoras teaches you to use modeling and quantification well while guarding the unquantifiable; the Yijing teaches you to generate complex systems from minimal rules; Huayan teaches you to replace lone-peak thinking with network thinking; Whitehead teaches you to favor process over finished product (mind "what am I becoming" rather than "what I am"). Together — mathematical leverage, mastering the complex through the simple, embedding in the network, embracing process — are the four inner disciplines of the super-individual of this age.
