Structuralism
Ladyman, French, Russell
Ontic Structural Realism holds that the fundamental constituents of physical reality are not objects with intrinsic properties but structures — patterns of relations that are ontologically prior to any relata. James Ladyman and Don Ross's 'Every Thing Must Go: Metaphysics Naturalized' (2007) argued that modern physics, from quantum entanglement to general relativity, systematically undermines the notion of self-subsistent individual objects, leaving only relational structure as the invariant content preserved across theory change. Steven French's 'The Structure of the World' (2014) developed this further, proposing that structures are all there is — objects are merely nodes in a web of relations with no independent reality. The tradition draws on Bertrand Russell's structural realism in 'The Analysis of Matter' (1927), which held that science reveals the structure of the external world but not its intrinsic qualities. This is distinct from linguistic structuralism (Saussure, Levi-Strauss), which concerns sign-systems rather than the structure of physical reality.
Worldview
The structural realist sees through the surface of objects to the mathematical relations that constitute them. What we call "things" — particles, fields, organisms — are not self-subsistent entities with hidden intrinsic natures but nodes in a network of structural relations that exhaust their identity. The electron is not a tiny ball with an unknowable inner life; it is the intersection of symmetry relations, conservation laws, and mathematical structures that our best theories describe. This orientation produces a distinctive intellectual experience: the world becomes transparent to its formal architecture, and the structural realist finds beauty and understanding not in the "stuff" of reality but in the patterns, symmetries, and invariances that survive across scientific revolutions. The framework classifies this as None: structuralism analyzes reality through relations and structures; no personal deity, cosmic ordering principle, or operative spirits are required by the framework itself. The framework reads this as Constructed moral authority: meanings, values, and norms are produced by the differential systems (language, kinship, exchange) within which they appear; no Scripture, Tradition, or transcendent Reason is final outside those structures.
Moral Implications
Structural realism complicates individualistic ethics by dissolving the notion of self-subsistent individuals with intrinsic moral worth independent of their relations. If persons are constituted by their structural roles — biological, social, informational — then moral consideration must attend to the relational networks in which individuals are embedded rather than to isolated selves. This supports institutional and systemic approaches to justice: changing the structure changes the individuals within it. At the same time, the structuralist must account for the felt reality of subjective experience, which resists reduction to abstract relational description. The moral challenge is to honor both the structural and the experiential dimensions of personhood.
Practical Implications
Structural realism is the philosophy of science most naturally aligned with contemporary physics, where symmetry principles, gauge invariances, and structural descriptions have proven more fundamental and enduring than any particular ontology of objects. Practically, this orientation supports the development of mathematical and computational tools for modeling complex systems — from climate models to economic networks — where the relational structure matters more than the identity of individual components. In technology, the structuralist approach favors modular, interoperable, and standards-based design, since what matters is the structure of the system rather than the intrinsic nature of its parts.
⧖
I. Time
Time is emergent from the relational structure of physical reality — Ontic Structural Realism holds that temporal relations are part of the fundamental structural furniture of the world, not properties of independently existing objects. Time is continuous, linear, and deterministic within the structural framework. Its extent is finite because the structure of the universe may have temporal boundaries.

✦
II. Space
Space is relational and structural — it is constituted by the network of spatial relations rather than existing as an independent container. Curvature is curved because the structural relations among physical entities determine the geometry. Space is local and three-dimensional at the structural level described by our best physical theories.

◉
III. Matter
Matter is emergent from structure — objects are nothing but nodes in a web of structural relations, with no intrinsic, non-structural properties. What we call "matter" is the pattern of relations itself. Matter is conserved and local within the structural description, but its identity is exhausted by its relational role.

IV. Observer
The observer is positioned within a structure — a system of rules, relations, and codes that precedes and shapes everything it can think, perceive, or know. Situated at a particular moment and location within the system, the observer's understanding is constrained by the structures it inhabits: language, culture, unconscious categories. Knowledge is always mediated and never transcends its structural conditions, yet structural knowledge itself is systematic and transmissible — it can be preserved and passed down through cultural and linguistic systems. The observer is embodied but passive in the sense that the deep structures do the real work; the individual subject is more a site where structures express themselves than an autonomous agent. Multiple observers share the same underlying structures.

V. Energy
Energy is emergent from physical structure — it characterizes the dynamical relations within the structural framework rather than existing as an independent substance. Conservation holds as a structural symmetry (Noether's theorem). Dispersibility is irreversible as a structural feature of the temporal ordering.

VI. Information
Information IS structure — reality is constituted by structural and informational relations, not by intrinsic properties of objects. It is discrete because structural relations can be fully specified by discrete mathematical descriptions. The framework distinguishes scales: information is conserved at the cosmic scale because structural relations are stable features of reality, but non-conserved at the personal-identity scale — a person is a node in structures that outlast them, but no individual pattern survives the dissolution of the node.

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 structural illusion — every event is fixed by the prior state.
On this view, the future is fixed by the present, and the observer is a recipient of causes rather than an originator of them. The sense of choosing is real — but what is being chosen is itself a consequence of brain states that were …

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's behaviour is the outcome of causes; 'responsibility' is a useful fiction, not a metaphysical fact.
On this view, the addict's brain state, history, genetics, and circumstances jointly produce the behaviour, and there is nothing inside the person that could have produced anything else. Calling the addict responsible is at best a social tool — useful for the deterrent and rehabilitative …

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.
An AI's behaviour is fully determined by training and input; 'responsibility' applies if at all to its makers.
On this view, the AI's output is a function of its training data, its architecture, and the input it received. There is no extra fact about the AI that could ground its responsibility, because there is no extra fact about the AI that could have …
Roads not taken
An AI without a free will is not the kind of thing that can be responsible. (69%) ·
The AI can be a genuine agent within determined conditions — and therefore genuinely responsible. (10%) ·
Neither AIs nor anyone else are the locus of free agency; the question is the wrong one. (6%)

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's apparent diversity is convention over a single underlying value.
On non-dual views, the diverse forms money takes are perspectival distinctions within a single underlying value — labor, energy, attention, or simply the One from which all value derives. The metaphysical question is mostly malformed at the conventional level where monetary policy lives, but the …

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.
Nations are conventional partitions of a single humanity.
On non-dual views, the distinctness of nations is a perspectival distinction within a deeper unity — one humanity, one consciousness, one underlying reality. Nations matter at the conventional level where ordinary politics lives, but the metaphysical weight they sometimes claim is unsupported.

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.
The distinction is conventional within a deeper non-dual reality.
On non-dual views, the distinctness of male and female — like every binary distinction between apparent selves — is a perspectival distinction within a deeper unity. Particular sex and gender designations operate at the conventional level where most of life is lived; at the ultimate …

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.
The distinction between edited and unedited is conventional within a deeper non-dual reality.
On non-dual views, the contrast between an 'edited' and an 'unedited' human — like every binary distinction between apparent selves — is a perspectival distinction within a deeper unity. The practical questions of safety, consent, and justice operate at the conventional level where most of …
Roads not taken
Human nature is a real biological kind given by reproductive biology or by creation; editing the germline transgresses what is given. (55%) ·

When does a person begin?
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?
From the standpoint of the One, the question doesn’t apply in the form it is asked.
On non-dual views, the apparent plurality of selves is itself a perspectival distinction within a deeper unity. The question of when one self begins within that One is conventional, not ultimate. What follows ethically is then a question for the conventional level — which is …

What is marriage?
Behind every disagreement about how marriage should be defined is a prior disagreement about what kind of thing it is — a given order to be recognized, a practice to be negotiated, or a web of relations to be woven.
All union is participation in the One — particular forms are conventional.
From the standpoint of non-dual traditions, the apparent distinctness of two people who marry is itself a perspectival distinction within a deeper unity. Marriage is one form of the underlying union all things participate in. The particular shape the institution takes is then a conventional …

What happens to "you" when you die?
Whether anything of you persists — and in what sense — depends on what you take a person to be.

What is our place in nature?
Whether humans are masters of nature, members of nature, or makers of nature is not a question climate science can settle. It depends on what nature is, what we are, and what kind of relationship is possible between us.
Humans and nature share an underlying unity — the separation was the mistake.
On non-dual views, the apparent distinction between human and non-human is itself a perspectival distinction within a single underlying reality. The work isn't to find our right relationship to a separate nature; it is to recognize that we were never separate. Climate harm, on this …

Should we colonize space?
The drive to extend human presence beyond Earth is sometimes framed as the next chapter of stewardship, sometimes as hubris, sometimes as escape from problems we ought to solve here. Which it is depends on what we take our relationship to nature to be.
From the standpoint of the One, expansion across substrate is just movement within the same.
On non-dual views, the difference between Earth and elsewhere is conventional — particular locations within a single underlying reality. Space colonisation as escape is therefore incoherent; nothing is escaped because nothing was elsewhere to escape from.

Prayer to a separate God presupposes a separation the non-dual view denies; the practice is remembrance and attunement.

Is the asymmetry between memory and anticipation a real feature of time, or just of us?
From the One's vantage, memory and anticipation are themselves conventional.

The offense is locally constituted by its substrate; when the substrate dissolves, the offense genuinely passes away.
