Topics — What a work is about. Nucleation holds whatever reading the owner files here, whether or not an Anthology of the SOTA topic could also hold it; instruction for ML practice belongs to the anthology (ADR-048). The words are seeded from the clusters the reading-time triage of 2026-09-25 found, and grow by decision.
Philosophy of biology — what life, organisms and biological functions are — teleology and function, organisation and closure, biological individuality and autonomy, and the demarcation of the living (group: philosophy; ADR-025).

| THEORY-071 v3 | Minimal agency requires individuality, interactional asymmetry and self-generated normativity, and individuality without the other two is not agency | Barandiaran, Di Paolo & Rohde (2009), LIT-566, read in NOTE-458. The three conditions are that the system distinguishes itself from its environment with no observer doing it, that it is the active source of modulations of its coupling with the environment, and that it regulates that coupling against norms its own organisation sets. Each is necessary, and together they are claimed to be sufficient. Individuality is the precondition of the other two and does not suffice. A cell in passive osmosis, a kitten warmed by its mother and a person with a Parkinsonian tremor are each individuals, and none of them is acting. The generative definition is an open autonomous organisation that adaptively modulates its coupling so as to maintain itself. Here “autonomy” and “self” mean organisational closure. They do not mean a subject or self-governance. Proposed: a conceptual analysis checked against intuitive cases, with an asymmetry criterion its authors call incomplete. | Proposed |
| THEORY-072 v4 | Organisms differ from dissipative structures such as a candle flame not by far-from-equilibrium self-maintenance, nor by circular self-maintenance alone, but by organisational differentiation: several distinct constraints that produce one another at different time scales | The record’s first answer to the demarcation question that NOTE-094 reports. Prigogine (LIT-516) supplies the dissipative structures, and nothing in his account separates them from organisms. Mossio, Saborido & Moreno (2009, LIT-570) grant a candle flame organisational closure. Its one macroscopic pattern keeps up the conditions of the combustion that makes it. They draw the line at organisational differentiation: in an organism several distinct structures make distinct contributions, where a flame makes “a unique contribution”. Montévil & Mossio (2015, LIT-582) narrow closure to mutual dependence among constraints. Each constraint must be both produced by and productive of another, with at least one slow and one fast dependence. On the record’s reading, that builds differentiation into closure, as Mossio and Bich (2014) already say of closure of constraints. No paper analyses a flame under the 2015 definitions. Neither paper says closure defines an organism. | Proposed |
| THEORY-073 v2 | In Friston’s 2013 formulation and the applications the record holds, a Markov blanket does not individuate a system: where it falls is fixed by modelling choices made before it is traced (the coupling graph, the internal set and the time at which steady state is assumed), and a blanket read from a fixed graph is the same whether the system produced the boundary or it was imposed | Bruineberg et al. (LIT-603) and Raja et al. (LIT-598) argue, by different routes, that the Markov blanket of the free-energy literature is placed and not found. The formal core is THEORY-066: the partition takes the internal set as input. This account adds what the critiques show about practice. In Friston’s soup (LIT-526) the graph was built from one kind of coupling and steady state was assumed when the run stopped. In published applications the blanket sits wherever the model needs it: in the receptors of a brain, the membrane of a bacillus, the beam joining two pendulums. The formalism also gives the same description to a membrane the cell makes and a beam nobody’s states make. So the blanket presupposes the boundary it is offered as the criterion of. Active since 2026-10-27, narrowed to the 2013 formulation and the applications held. The later steady-state definitions have not been read, and the unrestricted claim is THEORY-1097, Proposed. | Active |
| THEORY-135 v2 | Multicellular cooperation depends on suppressing cells that gain fitness at the expense of the organism, across five foundations (proliferation inhibition, controlled cell death, division of labour, resource allocation and maintenance of the extracellular environment); cancer-like cheating on them is found across the independent origins of complex multicellularity, so complex multicellularity can be understood as a system for detecting and suppressing cheaters | Aktipis et al. (2015), LIT-740. Multicellularity requires cell-level fitness to be suppressed; cancer is cheating on five foundations of cellular cooperation. A survey of the independent origins of complex multicellularity finds cancer-like cheating widely, division-of-labour cheating in every form. Proposed: a literature review whose survey is limited by what has been studied, with no model or new data. | Proposed |
| THEORY-141 v2 | In a major evolutionary transition, where formerly free-living units come to form a higher-level unit, the collective is stable only if selection between collectives comes to trump selection among the units within them, typically through mechanisms such as policing, kinship and division of labour that align the interests of the units; the levels at which selection acts are then a product of evolution, to be explained rather than assumed | Okasha (2022), LIT-749, restating with Buss and Michod a principle of the major transitions: a new collective can be undone by defectors, and succeeds only if higher-level selection trumps lower-level selection, usually through policing or aligned interests. The transitions make the hierarchy an explanandum. Proposed: a review stating general principles that Okasha himself says may explain any one transition only coarsely. | Proposed |
| THEORY-217 | A trait malfunctions when its operation does not correlate positively with the normative field, the minimum change its organization’s viability requires at each precarious state; malfunction needs no second order of regulatory norms, and regulatory traits can malfunction by the same standard | Barandiaran (2025), LIT-1026, read in NOTE-730. Against the dual-order account (Saborido, Moreno and Mossio), on which malfunction needs a regulated switch between regimes that a first-order trait fails to follow. The viability space has viable, precarious and terminal regions, and the normative field is the minimum constant parametric change at each precarious state that avoids disintegration. A trait functions when it correlates positively with the field, subfunctions when it does so too slowly, malfunctions when it does not, and is nonfunctional when it does nothing where it must. The standard is the organization’s own viability, not a designer’s goal, a selection history or a statistical norm. Proposed: a conceptual proposal with a one-variable model, and the field has not been computed for any real organism. | Proposed |
| THEORY-220 v3 | A far-from-equilibrium system that contributes to its own maintenance has functions relative to itself, with no history or observer needed, and one that switches among self-maintaining processes has indications of success that can be false by its own lights | Bickhard (2000), LIT-1029, read in NOTE-729. Function is contribution to a far-from-equilibrium system’s own persistence; the asymmetry between persisting and decaying gives function and dysfunction, always relative to the system served, so a parasite’s gut serves the parasite and harms the host. A candle flame has functions in this sense. Representation arrives with recursive self-maintenance: a system that picks its next interaction by how it has differentiated its environment implicitly predicates that the interaction will succeed, and can find the predication false. Proposed: a conceptual account, with no model, whose account of having a function (and so of malfunction) is deferred to another paper. | Proposed |
| THEORY-221 v2 | Organizational closure is a circular organization of efficient causes by which a system produces the conditions of its own existence, distinct from feedback, self-organization and catalytic cycles; systems whose loops do not regenerate the constraints that make them possible approximate closure without instantiating it | Rubin, Roli, Stano & Damiano (2026), LIT-1027, read in NOTE-727. A genealogy of closure notions from logic, cybernetics, systems theory, thermodynamics, relational biology and the biology of cognition, and an interpretive thesis drawn from it. The genealogy shows that “closure” names different things (information, operations, efficient causes, constraints, catalysts). The thesis picks efficient causes, adds that closure so read cannot be exhaustively described as a state-determined syntactic procedure, and concludes that current AI, agentic LLM systems included, is heteronomous. Proposed: the thesis is an interpretation, the irreducibility rests on Rosen’s unassessed arguments and a halting-problem argument the authors call provisional, and the AI verdict is drawn from the definition, not from analysis of any system. | Proposed |
| THEORY-232 | A whole can be compared in agency with its parts, relative to a chosen decomposition and the parts’ goals: it is more agential when its organization lets the parts resolve more of their mutual constraints than they do at the equilibrium of their former organization, which shows as delayed gratification | Watson (2023), LIT-990, read in full in NOTE-747. A perspective essay’s definition, argued and illustrated, not proved: agency of a whole with respect to its parts is the reduction in the parts’ total frustration at equilibrium that its organization achieves over the old one, shown by directed uphill excursions to lower minima. It is comparative and sets no threshold for an additional agent, and it holds only relative to a stipulated decomposition and stipulated goals for the parts. That bottom-up learning produces such organization is reported from earlier models, not shown here. | Proposed |
| THEORY-413 | ’Unit of selection’ names four separable roles, interactor, reproducer, manifestor of adaptation and beneficiary, and being an interactor at a level does not require engineering adaptations at that level, so showing that a level lacks them does not show it is not a unit of selection | Lloyd’s SEP entry (2005, revised 2024), LIT-160, read in NOTE-184. Her own programme, stated in the first person, and advocacy as well as a map. The four-question anatomy is the firm part. The diagnosis that conflating interactor and manifestor is “the most common error” is asserted, not counted. Its rulings on kin and group selection, the cheater problem and the Price equation are one school’s, not consensus. | Proposed |
| THEORY-418 v3 | A collective becomes a new level of individuality, on this sketch, only when collaboration toward a shared goal, rather than coordination or cooperation, organizes it and some core interactions have become generatively entrenched and, as the paper asserts without deriving it from entrenchment, it has organizational closure; such a community can then be reproduced only by exporting an organized sample of its roles and interactions, not of its members alone | Griesemer & Shavit (2023), LIT-188, read in NOTE-173. A conceptual sketch, so called by its authors, with no model, data or operational criteria. The paper’s two headline claims, that it describes evolutionary transitions non-circularly and that individuality is a special case of collectivity, appear only in the abstract and are not argued. Stage 3 is defined by a shared goal (§1), and §3 makes sustaining the community “a focal goal of every participating member”, which presupposes the group. The one argued conclusion, that inheritance at the new level evolves “in tandem”, is hedged and in tension with §2. | Proposed |
| THEORY-443 | Being a biological individual is not being an organism: evolutionary (Darwinian) individuality and physiological individuality come apart, and each is found among parts of organisms and groups of organisms as well as among organisms, so a part or a group can be an individual of one kind and not the other | Wilson and Barker (SEP, 2007; substantive revision 2024), LIT-168, read in NOTE-114. That organisms are not the only biological individuals is argued from examples; that evolutionary and physiological individuality is the most recognised distinction is a survey judgement. The nine-region framework that places each case is the authors’ own and tentative, and its figures draw as disjoint the categories the text says overlap. It offers no criterion of parthood and leaves holobionts open. | Proposed |
| THEORY-446 | Organism–environment reciprocal causation, taken diachronically, unrolls into an acyclic sequence of organism, environment and experienced-environment states joined by interventionist arrows; on that representation each niche-construction type has a characteristic causal pattern, and multi-species cases come apart only if organism and environment are kept distinct | Baedke, Fábregas-Tejeda & Prieto (2021), LIT-110, read in NOTE-111. A conceptual and visual model, worked by example for each type of niche construction and for two multi-species cases. There is no formal semantics, no completeness result and no empirical test; formalization is deferred. It sets synchronic co-constitution aside rather than refuting it, and the claim that the boundary is an “epistemic necessity” is stronger than the argument, which shows only that the model can draw one usefully. | Proposed |
| THEORY-448 | On a substance ontology, a gestated foster that is part of the pregnant organism either is no substance, so that mammals begin at birth and the foster is not the later baby, or is part and substance at once, which leaves no consistent count; a process ontology keeps both parthood and foster–neonate identity, at the price of a count between one and two that it does not define | Meincke (2021), LIT-142, read in NOTE-115. The critique of the Parthood View under substance ontology holds on its own and is the paper’s firm contribution. The positive view rests on five process-biology premises assumed for the sake of argument, and is programmatic by the paper’s own word; “something in between one and two” has no formal content. It keeps parthood rather than rejecting it, and it draws no ethical conclusion. | Proposed |
| THEORY-465 | Being reproduced does not entail reproducing: genes of multicellular organisms, like hearts, are reproducees with little reproductive autonomy and differ from hearts in reproductive causal control, and material overlap between parent and offspring is required of reproducers, which are whole life cycles, but not of reproducees | Bourrat (2025), LIT-157, read in NOTE-100. A definitional framework with no model or data. Both measures are recipes and neither is computed. The proxy for autonomy (conditional mutual information) measures resemblance given the environment, not the range of backgrounds the definition names, and the two recipes given for it differ. The overlap claim rests on a premise shown only for retroviruses, and the conclusion’s “necessarily” outruns it. | Proposed |
| THEORY-469 | Because persistence (mean absolute fitness at least 1) and selection (fitness differences) are logically independent, niche construction theory’s evolutionary niche, read externally as the factors producing fitness differences in a population, differs in extension from the realized population ecological niche even after unit and modality are matched, so it is not a simple translation of Hutchinson’s niche | Trappes (2021), LIT-169, read in NOTE-155. The non-identity follows from a conceptual argument the reading grades strong. The three kinds of case that populate the gap are weaker: habitat degradation rests on a projected persistence failure, commensalism on one field study after the author’s first candidate failed, and non-limiting resources on a “possible example”. The result is scoped to Odling-Smee, Laland & Feldman’s 2003 niche concept and to the externalist reading of selection pressure. It does not say the two niches differ much; they “still coincide to a large extent”. | Active |
| THEORY-473 | Scaled down to one organism, Hutchinson’s niche, defined as the conditions that give that individual an expected lifetime reproductive success of at least one, is observed only as a point; the rest of it is counterfactual, reached by translocation in only a few dimensions and otherwise inferred from other individuals, so in practice it is the niche of a phenotype class, and its authors call it mostly metaphorical | Takola & Schielzeth (2022), LIT-127, read in full in NOTE-170. The working definition (p. 5) gives the individualized niche an absolute-fitness boundary, expected LRS ≥ 1, and splits it into realized, potential, time-slice, prospective and trajectory-based niches. That the realized niche is a point and the potential niche unobservable follows from the definitions. The paper concedes there is “no empirical solution” at the individual level (p. 15), and its fix, marginalizing fitness functions across individuals, is schematic. It is a framework for structuring research, by its authors’ own account, not a measurement. | Active |
| THEORY-492 | Life was forced into existence by geochemistry: core metabolism, rooted in the reductive citric-acid cycle, formed as a channel relieving the free-energy stresses abiotic processes keep building, as lightning relieves a charge separation, so its early steps would recur on any similar planet and selection on metabolism came before replication | Morowitz & Smith (2006 working paper; Complexity 2007), LIT-528, read in NOTE-425. An essay with no calculation, which says itself that the thesis “has not been quantitatively demonstrated”. Its evidence is the structure of present-day core metabolism, read back into its origin. Its framework is Jaynesian entropy maximization over states that include currents, and it rejects entropy-production principles. The reading judged that no THEORY was indicated; this one is filed as Proposed, a conjecture with a stated research programme. | Proposed |
| THEORY-514 | Self-maintenance through closure of constraints does not single out organisms, since colonies, holobionts, symbioses and ecosystems meet it too, so a persister criterion applied at whatever level meets it turns organisms into parts; what is proposed to mark organisms is that they can also induce, control and come through phases of destabilised organisation and reach a new closure regime, though that only organisms can do so is asserted | Baedke (2025), LIT-167, read in full in NOTE-148. The negative half, that persister criteria are too permissive, is argued from the literature: closure has been applied to symbioses, ecosystems and eusocial colonies, and Mossio (2024) concedes that “organized systems are not necessarily organisms”. The positive half, the overcomer, is drawn “with rough brushstrokes” (p. 51) from three cases, two of which are lineage-level evolution or colony-triggered plasticity, and its uniqueness to organisms is asserted, with the one contrast (colony against ant) presupposing its verdict. Proposed. | Proposed |
| THEORY-532 | Systems pushed from equilibrium develop structures that degrade the applied gradient faster, and living systems and maturing ecosystems are such structures, continuous with convection cells and vortices, so the second law is a necessary but not a sufficient condition for life | Schneider & Kay (1994), LIT-533, read in NOTE-415. A “restated second law” (systems moved from equilibrium “utilize all avenues available to counter the applied gradients”) is offered as a corollary of Kestin’s equilibrium stability result and not derived from it. Bénard convection and a draining vortex show organized structures raising dissipation. One stressed marsh, airborne thermal scans and a satellite comparison are read as ecosystems developing to degrade more sunlight; all are correlational and confounded with water. The reading judged the claims too weak to source a THEORY; filed as Proposed. The paper itself says thermodynamics cannot tell the living from the non-living. | Proposed |
| THEORY-583 | An agent is the set of parts that pursue a goal together, bounded by the farthest events it can sense and try to regulate; cells joined by bioelectric coupling share measurements and so form larger agents with larger goals without ceasing to be agents, so a living system is many nested agents, not one, and cancer is the larger agent shrinking back to the cell | Levin (2019), LIT-439, a hypothesis-and-theory essay read in full in NOTE-341. A definition of the Self as a goal-pursuing collective, tied to a mechanism, gap-junctional coupling, from cited experiments on patterning and cancer. It has no model, no measurement of the light cone and no new data. Its goals are cybernetic set points, so any homeostat is a Self. Its Self is an agent and an individual, not a subject. The sentence against IIT’s single Self is a bracket, and the closing remarks on experience are labelled speculation. | Proposed |
| THEORY-607 | The individuals that appear in an evolutionary transition in individuality are a summary description of lower-level processes, not a new level of fact: a partition of particles defines collectives when predicting at the coarse grain matches predicting at the fine grain across many traits, and collectives become indispensable, and so quasi-ontological, only because finite measurement and computation make the fine-grained prediction unaffordable | Bourrat (2023), LIT-049, read in full in NOTE-064. The formal criterion is accuracy only: δC = C_T − C_P < θ across many traits, conditioned on the environment where ecology could fake coherence. As written it is degenerate, since the identity partition gives δC = 0. The cost that is meant to stop that is argued separately, by a 100-operation toy, and never put into the criterion. Nothing is computed on any model. The abstract’s “cannot be dismissed as merely epistemic” is stronger than the body, which says one “pretend[s] as if” the level of selection changed. | Proposed |
| THEORY-612 | Natural selection cannot be both a cause and an effect of a process such as niche construction: if selection is an emergent population-level process, niche construction partly composes it, and a whole and its parts are not independently fixable and so not causally related; if selection is not emergent, it is either no cause at all or incoherently individual-level. Niche construction can still cause the product of selection | Hazelwood (2023), LIT-156, read in full in NOTE-137. A dilemma against strong reciprocal causation in the extended evolutionary synthesis, aimed at Laland and colleagues. Emergence is Wilson’s synchronic dependence plus autonomy, cashed out as composition; causation is Woodward’s interventionism with independent fixability. Its force rests on a process/product split for selection and a compositional reading of realization, both defended by citation and flagged as contestable, and its second horn considers only two non-emergent options. The weak sense, that organisms and environments affect each other, is granted as unobjectionable. | Proposed |
| THEORY-628 v2 | Self-production alone gives a system only an all-or-nothing norm, to go on or to die, and that distinction is available to an observer, not to the system; a graded norm the system itself has, by which viable states are better or worse for it, needs adaptivity, a further capacity to detect tendencies toward the boundary of its viability and to act so as to reverse them, and sense-making and agency need adaptivity | Di Paolo (2005), LIT-1017, read in full in NOTE-719. A conceptual argument against Weber and Varela: autopoiesis in its original formulation entails conservation, not active homeostasis, so a bacterium whose intake is below consumption does not seek food “just because” it is autopoietic, and balancing at a cliff edge and falling over it both conserve autopoiesis. Adaptivity is defined, graded and recursive; pathology becomes failure of adaptivity while autopoiesis continues. There is no formal model, and the viability set is defined in one sentence. Proposed. | Proposed |
| THEORY-658 | Whether an account of organismal goal-directedness must separate genuine teleology from mere self-organisation, such as a candle flame, depends on what the account is for: a scientific model of agency need not and perhaps cannot draw the line, while an account of how mind and value fit into nature may have to, and need not be operationalisable | Nahas & Sachs (2023), LIT-192, read in NOTE-094 from the accepted manuscript. A metatheoretical argument: naturalising teleology serves at least two relatively autonomous projects, advancing biology and settling the naturalism debate, with different success criteria. It is worked on one dispute, the demarcation from dissipative structures. The positive pluralism (Deacon for naturalism, Walsh and the organisational approach for biology) is only “tempting to suggest”, and the boundary between the projects is never drawn. | Proposed |
| THEORY-666 | A system that produces itself, a network of production that regenerates the components which produce it and constitute it as a distinguishable unity, has by that fact an intrinsic purpose, the maintenance of its identity, and with it a point of view, valence and a world as distinct from an environment, so that teleology in organisms is real and not an observer’s as-if; the account is stated for the cell, and a multicellular organism is not itself autopoietic | Weber & Varela (2002), LIT-1018, read in full in NOTE-720. An essay of exegesis and convergence: Kant’s natural purposes read non-reductively, Jonas’s metabolism-based philosophy of the organism, and autopoiesis. The step from self-production to purpose is asserted (“Bluntly stated”), the step to subjectivity is Jonas’s phenomenological inversion, and no observable is proposed for the “empirical feature” the conclusion claims. What sets autopoiesis apart from dissipative structures is placed in “concern”, not in organisation. One paragraph runs from self-maintenance to a right to life. | Proposed |
| THEORY-673 v2 | The Price equation follows from any ancestor–descendant mapping in a closed population and is, like f = ma, a generalization-sketch: a schema that is empty of predictions until a specific model supplies entities, characters, time step and causes, whose value lies in unifying and guiding model construction, so the charges that it is a tautology or lacks predictive power and dynamic sufficiency ask of it what only its specialisations can supply | Luque (2016), LIT-205, read in NOTE-101 from the PhilSci manuscript. The derivation and the diallelic re-derivation are strong; the generalization-sketch reading is a moderate argument by analogy with f = ma plus two case studies, whose authors recovered results already derivable otherwise. The reply to “tautology” answers the word, not the critics’ point, which Luque concedes in §7.2. The paper’s prescription, that biologists should adopt the equation, is asserted without comparison. | Proposed |
| THEORY-770 | In a closed population, any mapping of ancestors to descendants gives the Price equation: mean fitness times the change in mean character equals the covariance of fitness and character plus the fitness-weighted mean of the change in character, over any time interval and with no assumption beyond closure | Luque (2016), LIT-205, §3, read in NOTE-101, after Price (1970); the derivation re-derived by the promotion audit. An identity, not a model: it says nothing about which partition of the change a causal model licenses, predicts nothing until fitness and transmission are specified, and fails without closure (migration). | Active |
| THEORY-874 | Whether a view of mind is organicist or informationalist is a dimension orthogonal to whether it is cognitivist or embodied, and the enactive approach of The Embodied Mind is set apart from other embodied views by organicism with experiential primacy and reciprocity, not by sensorimotor emphasis | Ward (2026), LIT-1356, read in the accepted manuscript in NOTE-1065. Views differ on where cognition’s processes are (skull or brain–body–world) and, separately, on what the meaning of mental states depends on (information, or organization distinctive of the living). Embodied predictive processing, extended functionalism and cybernetics are embodied and informationalist; the enactive approach is organicist, and further marked by experiential primacy and reciprocity. The sharp edge: it is a taxonomy argued from examples and exegesis. It does not argue that organicism is true, and the line between distinctive and characteristic properties of life is left without a criterion. | Proposed |
| THEORY-1097 | A Markov blanket, in any formulation including sparse coupling at nonequilibrium steady state and time-varying blanket states, does not individuate a system: where it falls is fixed by modelling choices made before it is found, so it presupposes the boundary it is used to find, and it cannot represent a boundary the system produces | The wider claim dropped when THEORY-073 was narrowed to Friston’s 2013 formulation and promoted on 2026-10-27 (ADR-047 v4: a narrowing’s dropped claims go to Proposed entries). Both critiques argue the general form, and the record holds neither of the later formulations it would have to reach. Its promote_when is THEORY-073’s own, moved here unchanged. | Proposed |
| THEORY-1119 | Barandiaran, Di Paolo and Rohde propose that minimal agency requires individuality, interactional asymmetry and normativity set by the system’s own organisation, each necessary and together, they say, sufficient; that individuality without the other two is not agency; and that a system optimizing an externally fixed function is not a model of agency | What the paper proposes, split from THEORY-071 by the tenth status review on THEORY-1110’s pattern, so that claims needing only the proposal can stand on it. The paper was read in full (NOTE-458), so the reading of what it proposes is held. Whether the definition is right, which turns on an asymmetry criterion its authors call incomplete and on applying the conditions to explicit models, stays THEORY-071’s question, Proposed. | Active |
| THEORY-1122 | Weiss’s mark of a system, that the whole varies far less than the summed variances of its parts, is met by any aggregate of independent parts when the whole is measured as their average; when it is measured as their sum, it holds only if the parts’ fluctuations compensate one another, with ∑ᵢ<ⱼ Cov(xᵢ, xⱼ) close to −½ ∑ᵢ Var(xᵢ) | Nicholson (2026), LIT-1821, read in NOTE-1340, reports Weiss’s one formula, VS ≪ ∑ (va + … + vn), as a property “we would invariably find, if we studied any system”, and as a way of identifying systems empirically. The variance of a sum settles what it can show. Active: an identity, checked numerically. It does not say Weiss’s systems lack compensating covariance, only that the inequality as stated does not test for it. | Active |
| THEORY-1126 | In animal development the organ-level outcome is reproducible while the trajectories of individual cells differ between embryos raised alike, so developmental regularity is imposed on variable cell behaviour rather than read out from a fixed sequence of cellular events (Weiss, as Nicholson reconstructs him), with invariant lineages such as that of C. elegans the conceded exception | Nicholson (2026), LIT-1821, read in NOTE-1340. Weiss’s “determinacy in the gross despite demonstrable indeterminacy in the small”, shown as a redrawn schematic (Fig. 5) and supported by citations to work on stochastic gene expression and cell-fate decisions. This is the only one of the paper’s four critiques that rests on evidence, and the paper presents none of the evidence itself. Proposed. | Proposed |
| THEORY-1166 | Di Paolo argues that autopoiesis as originally defined entails conservation and not active homeostasis, so it gives a system only an all-or-nothing norm, to go on or to die, which an observer and not the system can use; that a graded norm the system itself has needs adaptivity, a capacity to detect tendencies toward the boundary of its viability and to act so as to reverse them; and that sense-making and agency need adaptivity | What the paper argues, split from THEORY-628 by the twelfth status review on THEORY-1110’s pattern, so that claims needing only the argument can stand on it. The paper was read in full (NOTE-719), so the reading of what it argues is held. Whether the argument is right stays THEORY-628’s question, Proposed. It turns on three things: a reading of autopoietic theory that Di Paolo grants later formulations may not share (note 1), cases chosen to illustrate it, and its rival THEORY-666. | Active |
| THEORY-1247 | Griesemer and Shavit propose, as a first and rough sketch, that a collective becomes a new level of individuality only when collaboration toward a shared goal, rather than coordination or cooperation, organizes it, some core interactions have become generatively entrenched, and it has organizational closure, and that such a community can be reproduced only by exporting an organized sample of its roles and interactions, not of its members alone | What Griesemer and Shavit’s sketch proposes. The twenty-fourth status review split it from THEORY-418 (ADR-065 §3), so that the record holds the reading of the proposal apart from the proposal. The paper was read in full (NOTE-173), so the reading is held. Whether the proposal is right is THEORY-418, Proposed, which extends this entry. That needs criteria that sort real groups into the three grades, and worked cases. The paper’s two headline claims, non-circularity and individuality as a special case of collectivity, are in its abstract only and are not part of this entry. | Active |
| THEORY-1251 | Mossio, Montévil and Longo take organization, as closure of constraints, to be a theoretical principle of biology, posited a priori as physics posits its phase space and defining the domain together with variation, so that every system meeting both is biological by definition and organisms are one class of such systems; on this reading “organisms are organized” is constitutive, not an empirical finding, and the principle is to be judged by what it makes intelligible | Mossio, Montévil and Longo (2016), LIT-1888, §§1 and 4, read in NOTE-1461; the definitions are Montévil and Mossio’s (LIT-582, TERM-070). The paper states the principle’s status and scope and supports it by history and analogy; it derives nothing from it here. Proposed: what the principle buys is untested in this paper. It does not say that closure is observed in every organism, nor that only organisms realize it. | Proposed |
| THEORY-1271 | Mossio, Montévil and Longo argue that closure of constraints both stabilizes and propagates variation: it regenerates each constraint beyond the time scale at which it is conserved, and removes a variation only if the variation does not reach the constraints that regenerate the varied one; when it does reach them, the variation propagates and the system either loses closure and disintegrates or comes to realize a new closure, which they say a rock, a flame or a table cannot do | Mossio, Montévil and Longo (2016), LIT-1888, §5, read in NOTE-1461. The conditional is close to definitional. That regeneration actually recovers is a dynamical claim the paper does not model, and the contrast with non-organized systems rests on three examples. Proposed. It does not say how large a variation closure can absorb, nor that recovery follows whenever the structural condition holds. | Proposed |
| THEORY-1289 | In a dynamical model anchored to an identified mechanism, holding one part’s variable fixed and finding that the phenomenon persists indicates that the part is not a component of the mechanism responsible for that phenomenon, as when Smolen et al. fixed CLOCK and circadian oscillation continued; the verdict is relative to the phenomenon and only as good as the model, and it decides which pathways the phenomenon needs, not which lie inside the system | Bechtel and Abrahamsen (2010), LIT-1936, contribution C3 (p. 326), read in NOTE-1492. Smolen et al. (2001) fixed the concentration of CLOCK in a reduced model of the Drosophila clock, and oscillation continued. They concluded that the positive CLOCK loop “was not critical”. That is a part that belongs to the system and not to “the responsible mechanism for that particular phenomenon”. The clamp is an ideal intervention, cheap in a model and hard in vivo. It is not a test of where the system’s boundary lies. | Active |
| THEORY-1292 | Whether a coupled oscillator sustains its own rhythm or is a damped oscillator driven from outside is settled directly by removing the drive, and, because the two arrangements are not dynamically equivalent, may also show in how they respond to a shift of phase: in Leise and Siegelmann’s model, damped peripheral clocks regain their phase relation to the central clock quickly, while self-sustained ones take longer, need strong coupling, and sometimes resynchronize by a long delay instead of an advance | Bechtel and Abrahamsen (2010), LIT-1936, §3.6, p. 328, read in NOTE-1492. Peripheral clocks were once taken for “slaves” of the SCN, damping without it. Later evidence suggested they keep oscillating and lose synchrony, so the SCN is “a conductor” rather than “a ringmaster”. The paper’s reading is that models of both kinds “can reveal the empirical signatures that each may leave”. This is a biological instance of the record’s question where maintenance is realized. It is also a case outside CLAIM-522’s ideal limit: the outside drive does not reproduce the inside law, so a perturbation of state may tell them apart. | Proposed |
| THEORY-1351 | In West, Fisher, Gardner and Kiers’s account, a transition in individuality is defined by two separable conditions, mutual dependence (parts that once replicated alone can replicate only within the larger unit) and negligible within-group conflict, and proceeds by forming a cooperative group and then transforming it, with no clear border between the steps; across transitions what explains them is an ecological benefit to cooperation together with group formation that unites the members’ interests (clonal bottlenecks, lifetime monogamy, vertical transmission of clonal symbionts), while kin discrimination and the repression of competition played relatively minor roles | West et al. (2015), LIT-2003, read in NOTE-1538. A colloquium review: the definition and the two steps are the authors’ framework, and the explanatory claim is drawn from the comparative literature they cite. Proposed because they call it “tentative”, and because the theory for transitions between species is missing on their own account. It differs from THEORY-141 on mechanism: group formation, not policing, does the work. | Proposed |
