On Nature (fragments)
Fragments and testimonia on limiters, unlimiteds, harmony, and the central fire
Philolaus of Croton
· c. 440–400 BCE
· Doric Greek
· Prose treatise (fragmentary — surviving in Stobaeus, Diogenes Laertius, Nicomachus, Iamblichus)
Tradition: Pythagorean cosmology / pre-Socratic philosophy
Nature was fitted together from unlimiteds and limiters — the first mathematical cosmology, with the Earth in motion
Philolaus's "On Nature" is the earliest Pythagorean text to circulate publicly. The authentic fragments (principally B1–B7 in Diels-Kranz, with a larger set of testimonia in Aristotle, Aëtius, and later doxographers) set out a cosmology built on three principles: limiters (perainonta), unlimiteds (apeira), and harmonia — the "fitting together" of limit and unlimit through number. The cosmos has a central fire (Hestia, the Hearth) at its centre, around which revolve ten bodies: the counter-earth (Antichthon), the Earth, the Moon, the Sun, the five planets, and the sphere of fixed stars — ten to satisfy the Pythagorean reverence for the decad. The Earth is thus displaced from the centre, making Philolaus the first thinker in the record to propose a non-geocentric cosmos. The harmonia doctrine — that what makes a thing the thing it is, is its numerical ratio, not its material stuff — is the most radical mathematical ontology before Plato's Timaeus, and Plato's own late metaphysics (the Philebus's limit/unlimited pair) is deeply indebted to it.

School Embodiments
Pythagoreanism
50%
Philolaus is the principal written source for Pythagorean cosmology. The system of limiters, unlimiteds, and harmonia codifies what may have been oral Pythagorean doctrine.
"Nature in the cosmos was fitted together from unlimiteds and limiters, both the cosmos as a whole and all things in it." (DK 44 B1)
Structuralism
20%
Things are constituted by structural relations (ratios, harmonies) rather than by material substrate — a proto-structuralist metaphysics.
"All things that are known have number; for it is not possible for anything to be thought of or known without this." (DK 44 B4)
Plato's Timaeus and Philebus draw heavily on Philolaus. The limit/unlimited pair of the Philebus is a direct development.
"Plato, when he came to Italy, bought Philolaus's books." (Diogenes Laertius 8.85)
Rationalism
15%
The claim that reality is knowable because it is mathematical — number is the condition of knowability — is a rationalist commitment.
"It is not possible for anything to be thought of or known without number." (DK 44 B4)
Internal Tensions
The tension between mathematical abstraction and physical realism: limiters and unlimiteds are abstract principles, but the central fire, the counter-earth, and the ten bodies are concrete physical posits. Is the cosmos fundamentally mathematical or fundamentally physical? Philolaus holds both, and Plato inherits the ambiguity.
⧖
I. Time
Cosmic time is cyclical — defined by the revolution of the ten bodies around the central fire. The "great year" is the period of cosmic return. Time is substantival, continuous, and deterministic.

IV. Observer
The observer grasps reality through number. "All things that are known have number" (B4) — to know is to know the mathematical structure. The soul transmigrates, carrying its knowledge. The cosmic principle is impersonal mathematical necessity.

Do you really choose?
If the brain is a physical system and physical systems are governed by laws, then every choice is also a chain of causes — which raises the question of what was really left to choose.
Choice is real within a determined order — agency and determinism aren’t opposites.
On this view, the future is determined and you are genuinely choosing. Those aren't contradictory because the determination runs through you rather than around you: your reasoning, deliberation, and assent are the way the determined outcome gets settled. Choice is what it feels like from …

Are addicts responsible for their addiction?
Addiction looks from one angle like the textbook case of agency failing — a person doing what they don't, in any meaningful sense, want to do. From another angle it looks like agency at work in hard conditions. Which it is depends on what agency is.
The addict is genuinely responsible within a determined order.
On this view, the addict is acting within a determined order but is genuinely acting — making decisions, endorsing or resisting urges, seeking or refusing help. Responsibility attaches not because some uncaused choice happened, but because the addict is the kind of agent through which …

Should we hold AI systems responsible for what they do?
When an autonomous AI takes an action that harms someone, the question of who or what is responsible — the developer, the operator, the model itself — turns on whether the model is the kind of thing that can be a responsible agent.
The AI can be a genuine agent within determined conditions — and therefore genuinely responsible.
On this view, what makes a being responsible is not indeterminism but the kind of process the being is. An AI that deliberates, considers consequences, can be given reasons, and modifies its behaviour on reflection is doing what responsible agency is, even if its underlying …

How much weight do future people deserve?
If a billion people will exist in the 25th century, do their interests count for as much as the interests of a billion people alive now? The answer turns on what kind of reality the future has.
Past, present, and future are bound in cycles — duties span generations as a matter of course.
On these views, time is not a one-way arrow but a structure of return: cosmic cycles, karmic cycles, the seasons, the succession of generations. To act now is always also to act for the ancestors who shaped your inheritance and for the descendants who will …

Is regret rational?
If the past is fixed and unchangeable, what kind of mental act is regret? An error, a duty, a lesson, a perspective on a moment that is still in some sense present?
The past is part of a cycle one keeps returning to; regret is one of the gates of the cycle.
On cyclical views, the past is not a fixed thing behind you — it is part of the ongoing structure of return: karmic cycles, cosmic cycles, the cycle of seasons and generations. Regret, on these views, is less about an unchangeable past and more about …

What is money?
The question of what money is — a measured store of real value, an agreed-on practice, a relational ledger of debts, or just a name we apply to many different things — sits behind every argument about inflation, cryptocurrency, debt, and the state.
Money is the ledger of obligations among real people.
On relational views, money is not a substance you have; it is a record of who owes whom what. Debts and credits are real because the relations they track are real — to kin, to community, to ancestors, to land. Money is the form this …

What is a nation?
Whether a nation is a real moral community with intrinsic character, a constructed legal-political artifact, a web of kinship and shared history, an imagined community, or a conventional partition of a deeper unity — these are real ontological positions with sharply different political downstream.
A nation is the web of kinship, ancestry, and shared land that hosts a people.
On relational views, the nation is the relational fabric — extended kinship, ancestral inheritance, shared ecology, communal practice — that hosts a people across generations. Borders matter less than belonging; lineage and land carry the weight that political structures only ratify.

What makes someone male or female?
Whether sex is a real biological kind, a constructed social category, a relational identity, a label applied to varied phenomena, or a conventional distinction within a deeper unity is the ontological question the contemporary dispute about gender is mostly about.
Sex and gender are constituted by relations of recognition.
On relational views, identity is not a property a person has alone; it is constituted by the web of recognition the person sits in. What makes someone a man or a woman in any thick sense is the relations of kinship, community, ritual, and recognition …

Should we edit the human germline?
Whether human nature is a given biological kind, a constructed category, a relational achievement, a family-resemblance cluster, or a conventional distinction within deeper unity is the ontological question the policy debate over heritable gene editing is mostly about.
Personhood is constituted by relations of descent and kinship; germline editing reshapes the relational fabric.

Is the world created from nothing?
Creatio ex nihilo is one of the most distinctive Western-theological claims. Whether matter was created from nothing, eternally exists, or is sustained moment-by-moment turns on what kind of thing matter is.
Matter is constituted by relations; the question of 'from what?' presupposes substance.
On this view, matter is not a stuff but a patterning — the standing relations among things, ancestors, processes, and places. The creatio-ex-nihilo question doesn't quite arise, because the ontology has no slot for a free-standing substance to be created or eternal. What persists is …

Is reality fundamentally digital?
Pancomputationalism, Planck-scale quanta, simulation theory and Kabbalistic letter-mysticism all say yes — but for very different reasons. The rest of the atlas says no.
Yes — but divinely-discrete: divine letters, momentary cognitions, atomistic theism.
On this view, the world is at bottom discrete, but the units are not bare bits. They are divine names, momentary cognitions, karmic atoms, sacred letters — the elementary acts of a creating or ordering agency. Discreteness is real and fundamental, and so is the …

Yes, theistic atomism — actual occasions, divine letters, momentary cognitions.
On this view, the atoms of experience are not bare quanta but agent-laden moments: Whiteheadian actual occasions in which subjectivity and the divine lure meet, Kabbalistic letter-cognitions in which divine names act, Buddhist Abhidharma moments of mind, tantric ksana.

Is memory stored or reconstructed?
Engrams and traces — or continuous re-narration each time you remember? The cognitive-science debate has a theological cousin: divine memory holding each hair, or the ancestors' continuous remembering.
Stored — in divine memory's discrete particulars, or in karmic-record units.
On this view, memory is held in discrete particulars by an agency: the Lord who knows each hair, the karmic ledger that records each act, the angelic scribe who writes each deed, the Kabbalistic letters that spell each soul. Storage is real; the storer is …

The political question of abortion sits atop an older ontological one: at what point does there exist a someone — a being with moral standing — rather than merely the materials from which one will form?
