1. From Form as Model to Form as Event

1.1. The Problem of Form: Heritage and Presupposition

The entire Western philosophical tradition, when speaking of form, presupposes a causal relationship so naturalised that it is rarely articulated: form is cause, model, essence, law, or regularity that matter follows or realises. This presupposition is not innocent, it is the result of a specific conceptual operation occurring at multiple points across the tradition, within seemingly distinct regimes. It is not that the tradition simply ignored instability or becoming, it ignored them precisely because it subordinated everything to a regime of form that was transcendent or immanent, yet always determining. The question never asked, the question suspended throughout philosophical genealogy, is elementary: what if form does not pre-exist? What if form is not an orienting cause, but an effect that emerges when specific constraints combine?

This presupposition of form as cause appears across distinct registers, in contexts seemingly incommensurable, yet with identical grammar. In Platonic Forms, the perfect, eternal, immutable model, of which imperfect copies in the sensible world are mere shadows, incomplete participations. Form lies on the side of true being; matter on the side of illusory becoming. In Aristotle's formal cause, form as that which makes a thing be what it is, the principle determining identity and essential properties. Form is immanent, yet it remains that which determines; matter is that which is determined. In modern science's "laws of nature", regularities that "govern" as though external to matter, or at least external to the concrete material event. Command commands. In every instance, matter is conceived as fundamentally passive, it receives, realises, obeys. Form is active, orienting, determining.

Yet this framework suffers from an internal incoherence that the history of philosophy never managed to resolve, only to sophisticate. If form pre-exists matter (Platonism), how does form come to be present in the material world? How does the eternal act upon the temporal? If form is an immanent cause (Aristotelianism), how is form not simply a material property, indistinguishable from matter? Why is form not merely a name for the configuration we observe? The history of modern philosophy consists of attempts to resolve this incoherence while rigorously preserving the original presupposition: Descartes with the clear and distinct idea represented by the mind; Leibniz with the intelligible "programme" contained in every monadological substance; Kant with the a priori structures of knowledge that make knowledge possible but are not themselves known. None of these solutions escapes the fundamental dilemma: form is either exterior and inexplicable in how it acts upon matter, or interior and thus indistinguishable from matter, reducing to mere description.

The solution lies not in refining the presupposition, it lies in abandoning it. Not because it is false, but because it is an ill-posed question carrying inside itself a presumption undeserving of being presupposed. Form is neither cause nor model. Form is what happens when material constraints, under specific conditions, come into friction and crystallise into recognisable configurations. Form is an effect of the material process, not its cause. This is not a reduction of form to amorphous matter, it is the recognition that form is a property of the process, not a principle separate from the process.

This displacement is not purely speculative. It has observable roots disclosed by twentieth-century science. Non-equilibrium chemistry (Prigogine) demonstrated that organised structures can emerge spontaneously far from thermodynamic equilibrium, without a prefiguring programme, without a formal cause to orient them. Order is no rare exception, it is a predictable consequence of dynamics when certain thresholds are crossed. Non-linear dynamics revealed that simple deterministic systems can generate complex patterns from simple rules, not because the pattern was "hidden" within the rules, but because the rules produce that pattern when acting under specific initial conditions. Self-organising systems (growing crystals, forming dunes, pulsating turbulences, biological population patterns) reveal that material order can emerge from local interactions without global coordination, without a prior plan, without a determining essence. In all these cases, observable, measurable, replicable, there is no "pre-existing form that matter realises". There is a process that makes form. Form emerges when conditions are such that materiality cannot arrange itself otherwise. The philosophical challenge, the true task, is to describe this process without re-enchanting matter with terms belonging to the regime of transcendent form, without projecting onto raw material the properties that only the symbolic regime possesses.

1.2. Genealogy: Six Strategies of Form Capture

Plato installed an argumentative pattern that would contaminate the entire subsequent tradition. It is not a matter of considering him merely as a historical starting point, it is a matter of recognising that in Plato a conceptual operation crystallises which, even when criticised or reformulated, is never truly abandoned. The doctrine of Forms (or Ideas) states the following: what is truly real is the Form, the perfect, eternal, immutable model, subsisting in itself, unaffected by becoming. Material copies in the sensible world are degradations of that perfection, shadows, incomplete participations. Form is not a property of matter, it is the model in which matter imperfectly participates. The ontological consequence is clear: permanence is worth more than change; the model is worth more than the realisation; the immutable is worth more than becoming. This is not a neutral theoretical stance on how to know, it is an ontological operation that places different layers of being into hierarchies. Form is true being; matter is non-being (in the sense of being mere potentiality). The difficulty Plato himself encounters, the problem of the "third man", the impossibility of explaining how participation functions, does not lead to the refutation of the fundamental scheme. It leads only to its permanent sophistication in Aristotle, in Kant, throughout subsequent metaphysics. The pattern persists: form = orienting cause/model/essence.

Aristotle criticises Plato on fundamental points, yet retains the essential: form is that which makes a thing be what it is. He rejects the separate world of Forms, form is immanent, inseparable from matter. Yet he maintains that change must be understood in terms of form: matter possesses the capacity (dynamis) to receive form (morphe); the realisation of that capacity is actualisation (energeia). Form is that which actualises the potential of matter. The identity of a thing lies in its form, not its matter, matter is that which is subject to change, form is that which remains. The consequence is insidious: if form is what makes a thing be what it is, if form is that whose presence determines the identity of a thing, then discovering forms is discovering the essences of things. And if there are essences, there is an order in matter that precedes any human observation. The task of science becomes the discovery of hidden forms, not the description of processes. This Aristotelian pattern would dominate all medieval and modern metaphysics, and all biology, from the medieval notion of "species" (a thing defined by specific essence) to Mendelian genetics, where the "gene" functions as a tiny immanent form, a small material essence predetermining development.

Differentiation from the position developed here: Aristotle maintains that form is immanent yet still a determining cause; here, form is a (contingent) effect of resolving material constraints, without any formal cause governing them. Immanence is retained, everything is material, everything is process. Causality is refused, no form determines what matter does.

Spinoza rejects God as an external cause of order, everything is immanent to the Single Substance. There is no transcendent God creating and governing the world; there are no two substances (thought and extension separated) miraculously coordinating. There is a single Substance expressing itself simultaneously as thought and extension. Yet what Spinoza gains in immanence he loses in freedom: if everything is Substance, then the order we observe is not contingent, it is the necessary expression of Substance's geometric nature. Everything that exists is necessary; nothing could be otherwise. Spinoza seeks to dissolve God yet retains the divine as an eternal structure of determination, Substance does not choose, does not deliberate, merely is; and all that is flows necessarily from that nature. His system offers radical immanence, eliminating external causality, but at the price of absolute necessitarianism. For Spinoza, everything is eternal and geometrically necessary.

Differentiation from the position developed here: Spinoza's immanence is retained (there is no external cause, everything is material process), but necessity is rejected. For Spinoza, all that exists is necessary and eternal (the geometry of God). Here, all that exists is contingent and transitory. The geometry of matter is not necessary, it is compatibility that could have been otherwise had initial conditions differed. Differentiation: Spinoza retains immanence and geometric necessity; we refuse necessity, retaining only immanence and constitutive contingency.

Bergson criticises all Western philosophy for domesticating becoming within static categories, form, essence, law, structure. True becoming is continuous creation, not the realisation of a plan. Life does not follow a plan, it invents continuously. Yet Bergson places the source of this creation in an interior capacity of life, the élan vital, a creative impulse that orientates without being a law. This remains, in a sense, transcendent form, merely relocated to the interior of life rather than a separate Platonic world. Creation comes from within, but comes from a principle that precedes and orientates, the vital impulse.

Differentiation from the position developed here: Bergson's critique of staticism is maintained here, order is not the realisation of transcendent form, it is continuous creation. But the élan vital is rejected: creation comes from material frictions, from colliding constraints, from resolving incompatibilities, not from a unified creative impulse permeating life. Form does not emerge from a tendency towards organisation, it emerges from specific, local encounters between material forces. Differentiation: Bergson retains creativity irreducible to law, refusing the quantitative homogeneity of space; here, creativity is retained, the unifying vital principle is rejected as a source, pure material heterogeneity is maintained, without unity, without a shared impulse, only diverse and local processes.

Whitehead (in Process and Reality) criticises the Western tradition for separating form and matter as though distinct substances, true unity is process. Concrete entities are not "things" with properties; they are processes, events, occurrences. Forms are abstractions from these processes, useful for analysis, but not fundamental. Simondon (in L'Individuation à partir des systèmes) goes further: there is no preformed individual, no essence determining what something is. The individual is the outcome of an individuation process that never truly completes, it exists always in a state of quasi-stability around a pre-individual state.

Differentiation from the position developed here: The position developed here receives this heritage: form is not a substance separate from matter, it is the continuous reconfiguration of material compatibilities. Process is fundamental, not forms. Yet there are important differences. Whitehead places at the heart of every process a "prehension" (a proto-conscious experience of one event by another event), this is a projection of the symbolic/mental dimension onto the pre-symbolic. This is rejected: there is only material process, without prototypical experience, without proto-consciousness. Simondon speaks of a "pre-individual charge" as that which resolves in individuation, there is a tendency towards resolution, towards stabilisation around a defined individual. Here, we speak of "excess" as that which does not resolve, persisting as a permanent source of instability and reconfiguration. Metastability is not quasi-resolution, it is constitutive irresolvability. Differentiations: Whitehead retains processuality and creativity, rejecting proto-experience and eternal objects. Simondon retains metastability as permanent and retains the notion of a partially resolving charge; here, we radicalise this: excess as permanently unresolved, a continuous source of differentiation.

Deleuze (in Difference and Repetition) shows that the tradition confused difference with diversity. Diversity is multiplicity within a genus, many exemplars of a single form, with variations. True difference is that which cannot be reduced to any genus, that which is creation without a prior model. It is difference that generates creation, not the realisation of a pre-existing form. Prigogine (in The End of Certainty) demonstrates experimentally what Deleuze theorised: in systems far from equilibrium, the irreversibility of time is constitutive, not merely statistical. Novelty emerges not through the tightening of a pre-existing law, but as genuine bifurcation at critical points where multiple futures are possible.

Differentiation from the position developed here: The position developed here integrates this insight: the form emerging from friction is not the realisation of a model, it is the material opening of possibilities uncontained in anything prior. Contingency is not ignorance (as Laplace imagined, the Demon knowing everything could predict everything). It is a property of the material real. Differentiations: Deleuze retains the virtual/actual distinction as fundamental, there are virtualities that actualise. Here, the virtual is viewed as a useful symbolic fiction for thought, but not as a property of the real. There is only the real (material process without capture) and the concrete (the real rendered legible via a symbolic regime). Prigogine retains dissipative structures as order emerging far from equilibrium. Here, "order" as a category is rejected, there is only contingent configuration, compatibilities that resolve, without this constituting "order" in the sense of a necessary structure.

1.3. Scientific Anchoring: The Immanent Genesis of Form

Crystallisation is the most elementary paradigm where form emerges without a pre-existing model, without a formal cause governing it, without a programme prefiguring it. It is not a metaphor, it is an observable, measurable, replicable phenomenon. A salt crystal does not "follow" a pattern, the pattern emerges from the compatibility between sodium and chlorine atoms when they approach under specific conditions: temperature, concentration, pH, presence or absence of impurities. The cubic geometry of the crystal is nowhere before crystallisation, it is in no World of Forms, it is not encoded in a gene (salt has no gene), it is not foreseen in a law of form. It emerges from the resolution of electrochemical tensions. The atoms approach, their electronic charges create repulsion and attraction, the atoms reorganise until finding a configuration where tensions balance. That configuration is the crystal. The observed symmetry is not a model being realised, it is a consequence of electrochemical compatibility. If temperature changes, the crystal changes. If concentration changes, the crystal changes. If impurities are present, the pattern deforms. No form is eternal, all crystals grow, reach equilibrium, then may dissolve if conditions reconfigure. This is a brute fact of ordinary chemistry. No magic, no essence, merely matter rendering itself compatible under physical constraints.

This is the paradigm that all subsequent analysis generalises: at every scale of material organisation, form emerges from resolving constraints, not from realising models. The crystal's geometry is perfect for illuminating this because it is minimal, observable, repeatable, there is no mystery, no lacking capacity of "understanding". It is pure ordinary chemistry, so common it rarely merits reflection. Yet it contains the conceptual structure that all material organisation exemplifies.

Polymorphism is the phenomenon that definitively destroys any idea that the "essence" of material determines form. The same material, the exact same atoms, can crystallise into multiple radically different forms, depending on pressure, temperature, and other precipitation conditions. Carbon crystallises as diamond or graphite, two solids with completely different properties (hardness, conductivity, appearance), yet they are the same element. Calcite and aragonite are both calcium carbonate, same chemical formula, different geometries. This destroys all essentialism: the "essence" of material does not determine form. Form emerges from external conditions. The same material under different constraints makes radically different forms. This means: there is no reading of form from material constitution. Form does not flow from the "nature" of material. Form is an effect of the configuration of tensions in a specific context. The lesson is definitive: there is no essence determining form, form is contextual, transitory, contingent.

Polymorphism functions as a proof of principle against essentialism: if the "essence" of carbon were diamond, it could never be graphite under pressure, it would be an ontological contradiction. But reality shows that the same "essence" (carbon's atomic constitution) is compatible with multiple forms, depending on the context of realisation. This reveals that "essence" (molecular structure) is not what determines form, it is external constraints, conditions of temperature and pressure, that determine which material potentiality will crystallise. Material contains multiple compatibilities, and which compatibility materialises depends entirely on specific circumstances. Order does not come from material "in itself"; it comes from the resolution of tensions between material and contextual constraints.

Expanding the scale: a cloud of gas and cosmic dust does not "follow" the form of a star, the star's form emerges when mutual gravitational attraction overcomes the thermal pressure of the gas. The sphere is the least energetic configuration (lowest potential energy for this mass distribution), gravitation does not "force" the form, materiality simply reorganises into a configuration where tensions balance minimally. This resolution is not the expression of a star's "essence"; it is the mechanical result of a cloud collapsing under a specific regime of forces.

The process of gravitational collapse is exemplary because it shows clearly that form does not pre-exist: prior to collapse, the gas cloud is formless, without apparent structure, a dispersed distribution of molecules in a regime of thermal pressure. But as cooling permits gravity to gain dominance, this formless distribution crystallises into a geometry, the sphere, not because the sphere was "encoded" anywhere, but because the sphere is the configuration that minimises gravitational potential energy. Form is a solution to a material problem: given this quantity of mass in this gravitational regime, what configuration stabilises? The answer is the sphere. This is the answer to the friction between "I want to disperse" (gas thermal pressure) and "I want to collapse" (mutual gravitational attraction). As temperature drops, friction rebalances in favour of gravity, and collapse begins.

When the star ages and nuclear fuel dwindles, tensions reconfigure: it may collapse into a white dwarf (electronic repulsion overcomes gravity), a neutron star (nuclear forces overcome gravity), or a black hole (gravity collapses everything). None of these forms is essential to the star, each is an effect of reconfiguring forces when certain thresholds are crossed. A star's fate is not prefigured at its birth, it depends entirely on one variable: its mass. Stars of different mass end in completely different forms. A star of eight solar masses dies as a white dwarf; one of twenty solar masses dies as a neutron star; one of one hundred dies as a black hole. Death is not a drop into a pre-determined essence, it is a material bifurcation in response to values exceeding critical thresholds.

The pattern is identical to that of the crystal: form is the provisional resolution of transforming constraints, not the prefiguration of a model. The difference is scale (cosmic gas vs. aqueous solution), dynamics (gravity vs. electrochemistry), and duration (a billion years vs. seconds), yet the logical structure is entirely identical. In both cases, material compatibilities resolve into a specific configuration, and that configuration persists for as long as the constraints that produced it continue to operate.

Turing structures and non-linear dynamics offer genuine understanding of how complexity emerges from simple local rules. Alan Turing demonstrated (1952), through mathematical analysis of chemical reactions under heterogeneous diffusion, that extraordinarily complex patterns, spots, stripes, ripples, can emerge spontaneously without global instructions, without a pre-existing pattern orienting formation. The origin of these patterns is pure local dynamics: a chemical reaction produces substance A in a particular zone, substance A diffuses to a neighbouring zone, reacts with substance B, and the reaction produces an inhibitor blocking local formation of more A, thus creating a pattern wave. No one "draws" the pattern; no genetics are involved; no instruction in DNA prefigures the result. There is only compatibility between chemical rules and diffusion geometry producing, necessarily, these structures.

Examples abound in nature: sand dunes are not "taught" to take crescent form by sand grains, the grains obey local rules (friction, cohesion, wind action) and the crescent form emerges as a consequence of aggregating local behaviours. Turbulence patterns in fluids, vortices, eddies, bifurcation cascades, emerge from Navier-Stokes rules applied locally without anyone specifying global form. Convection structures in Rayleigh-Bénard convection, the transition from conductive to convective regime when temperature exceeds a critical threshold, emerge from incompatibility between thermal destabilisation and viscous resistance, resolved into a pattern of hexagonal cells. Pigmentation patterns on animal coats (zebra, leopard, giraffe) obey, very likely, Turing reaction-diffusion dynamics: embryonic animal development brings two cellular populations producing different pigments into contact, diffusion creates gradients, and reaction between gradients produces a pattern of stripes or spots. The pattern emerges from local dynamics, it is not encoded in the gene; only the capacity to produce pigments is encoded; the specific pattern is an effect of diffusion geometry and reaction.

This makes form contingent, had local rules been slightly different (different chemistry, different diffusion coefficient, different geometry), form would be radically different. Two animals with the same "pigmentation" gene can have completely different patterns if developing at different temperatures during embryogenesis (altering the pigment diffusion coefficient through temperature alters the final pattern). This also makes form stable, for as long as rules hold, form persists recognisably. There is no hidden model, there is only the material emergence of pattern from local dynamics, incompatibilities resolving into observable structure.

1.4. Three Founding Distinctions

The Western tradition confused law with form, treating them as though identical. Yet they are radically different. A law is universal, necessary, timeless, valid always and everywhere, applicable to all contexts where its conditions are verified. A form is contingent, transitory, localised, existing only for as long as the specific conditions producing it remain combined. A crystal follows laws of chemical and electrostatic bonding, yet the form of the crystal (number of faces, symmetry, size) is not derived from the law of bonding. Form is derived from the resolution of constraints within a specific context. Describing laws is not describing forms. Physics describes laws, relations holding universally. Chemistry describes how those universal laws produce material conformities within specific contexts. The confusion between law and form is a slide into essentialism: the belief that law determines form, that knowing the law means knowing the form. But law is one dimension, form is the result of law acting within a situation. Different situations produce different forms under the same laws. Law does not specify form, it merely constrains it.

The tradition used the word "essence" to perform two completely different tasks simultaneously, creating permanent confusion. An essence had to describe ("this is what the thing is") and prescribe ("this is what the thing must be, its necessary nature"). Description is an account of what is observed in this context, properties the thing possesses in this situation. Prescription is a declaration that this is necessary, that the thing "realises" an essence, that it could not be otherwise. These are completely different operations. When we abandon the idea of transcendent form as cause, we can separate these functions. Description says: "under these specific conditions, this configuration of properties emerges". Prescription vanishes, there is no ontological duty, only material conformity to local constraints. This liberates thought from the ontology of the necessary. Everything is contingent, it could have been different. Yet everything is also conformed, it is not chaotic, it follows patterns, it possesses specific compatibilities.

The tradition placed the model as prior and repetition as posterior, the model is cause, the copy is effect, repetition is an imperfect imitation of the model. Yet when we observe nature, we see no copies of a model. We see the repetition of conditions producing variants upon a pattern. Two salt crystals are not "copies" of one another, both are products of the same chemistry in slightly different contexts (slightly different temperature, concentration, pH). Forms are similar but not identical, there is variation. Two snowflakes do not reproduce a "snowflake model" existing in some ideal realm, both emerge from water condensing into crystals under slightly different regimes of temperature and humidity. No perfect copy, only a recognisable pattern with permanent variation. This completely repositions thought on form: there is no hidden model, only the material reproduction of similar circumstances generating variants. Variation is constitutive, not exceptional. There is no ideal type that instances imperfectly realise, there are only populations of forms produced by similar processes with outcomes always slightly different.

Form is not what matter is. Form is what matter does.

2. Essence as Symbolic Effect

2.1. Genealogy of Essentialism: From Aristotle to Biology

The question of essence runs like a metallic thread through the entire Western philosophical tradition, and perhaps no question is more central to understanding why form persists, nor more misleading in the answers it offers. To comprehend the present of organised matter, it is necessary to exhumate the history of how we attempted to fix what cannot be fixed, how each era relocated the foundation when the previous location proved untenable.

Aristotle formulated the question with a precision that still resounds across two thousand years. Essence, ti esti, that which a thing is, is not one property among others; it is that which, if removed, leaves the thing no longer what it is. Remove colour and the object remains; remove geometric shape and it remains; but remove the essential quality and the object itself vanishes. An animal is essentially an animal because it has a soul coordinating its parts according to purpose; a metal is essentially a metal because it has a crystalline structure granting it rigidity and thermal/luminous conductivity. Essence is a cause, not an efficient cause (that which moves or produces movement), but a formal cause (that which makes a thing be what it is, granting it identity and enabling recognition).

This definition is powerful because it offers simultaneously a criterion for intelligibility and a criterion for classification: things with the same essence belong to the same genus, and different essences explain cosmological diversity in genera and species. Everything we observe as change is, within this scheme, an alteration of accidental properties, the cloth changes colour and size (accidents) yet remains cloth (essence). A child grows, matures, grows rigid (accidents) yet remains human (essence). Change is intelligible because there is something immobile beneath, the essence persisting while everything else fluctuates, changes, transforms.

The power of this conception is twofold. It offers an answer to the problem of flux, how is there knowledge and stability if everything is in motion?, through the distinction between essence (immobile) and properties (mobile). And it offers an answer to the problem of diversity, how is a thing one (possessing identity) if its constituents change continuously?, through form that persists. Essence unifies; essence remains; essence is the cause of being.

Yet there is a profound presumption here that is rarely articulated: the presumption that there is something immobile and definable, something whose nature cannot vary, at the heart of every thing. The history that follows is a history of permanent attempts to safeguard this presumption despite growing evidence that change is more radical, deeper, more constitutive than Aristotle admitted. Essence must remain fixed while everything changes, yet how can it be immobile if it is within movement? Where is this immobility located? At what temporal scale does it exist? These questions prove increasingly intractable the more precisely we pose them, and every attempt to answer one creates fresh difficulty in the others.

Modern science inherited this presumption but relocated it cleverly. Essence ceases to be a Platonic Form (eternity outside time) or an Aristotelian immanent form (in matter itself yet immobile); it becomes a material property: the "nature" of a thing, its "constitution", its microscopic structure, that which makes it function as it functions and not otherwise. If essence cannot reside outside the material world, it resides within it, in a structure that, though invisible, can be discovered through systematic investigation.

Nineteenth-century chemistry exemplifies this strategy clearly. It sought the "essential properties" of elements, a radical attempt to reduce all observable phenomenal diversity to simple elementary essences. Mendeleev in 1869: sixty-three known elements, each representing a fundamental type of matter? This seemed to fill perfectly the space left by Aristotelian form, matter finally had discovered essences, and all chemistry was a combinatorics of elementary essences. Periodic order emerged as the confirmation of hidden structure.

Twentieth-century genetics inherited the exact same search strategy, but relocated once again. The gene was treated, methodologically at first, then ontologically, as the essence of heredity: the hidden cause of visible traits, the ground of all physiognomy, the secret explaining why offspring resemble parents, why traits persist across generations. The discovery of DNA's structure by Watson and Crick in 1953 confirmed and expanded this intuition to a new level: here finally was the ultimate essence, a molecule encoding the integrity of an organism, a structure persisting and replicating, an information pattern remaining immobile while the body ages, transforms, and dies.

Yet a persistent problem remains, a problem emerging only when we seek to apply the discovered essence: the more sciences advance in precision and detail, the less they find essences in the sense originally sought. Properties of "elements" reveal themselves as radically contextual, oxygen behaves differently in iron oxide compared to water; gold does not behave as an isolated gold oxide does when alloyed with copper or silver; chlorine is a lethal poison in isolation yet an essential component of life in sodium chloride. An element's essence is not what determines it in a real situation, it is merely an aggregation of properties occurring when isolated in an artificial laboratory context.

Genes do not determine traits in the manner classical genetics claimed. A gene does not encode a complete eye; it encodes a protein that, under specific contexts, environmental conditions, and interactions with other genes, contributes to a process that, if all goes well, produces an ocular structure. The same genetic sequence produces radically different phenotypes depending on environment: a Drosophila melanogaster organism with an identical genotype can develop large, fully functional wings or non-functional vestigial wings, depending on temperature during development. Epigenetics, discovered at the turn of the twenty-first century, shows that genes can be silenced or activated without any change in DNA sequence, what persists is not a genetic code (immobile), but a regulatory pattern (mobile, contingent, responsive).

The metaphysical promise, to find in molecular biology the essence of life, that which makes it alive, dissolves into a tangle of contextual dependencies, epigenetic regulations, and signalling flows varying according to circumstance.

Biology consolidated essentialism in a particular and exceptionally powerful manner: through the category of "species". A species is conceived as a natural class of organisms sharing a common essence, mutual reproductive capacity (different species cannot produce viable offspring), similar genotype (recurrent chromosome and gene pattern), typical anatomy (recognisable structural traits permitting identification). Species was the natural unit around which all biological diversity organised itself, and species essence explained why members were similar to one another and reproductively isolated from other organisms. Here essentialism found fertile ground: on the surface there was diversity, millions of different organisms, yet underneath there was simplicity, each organism was a member of a species with a defined essence.

Darwin undermined this methodologically and irrefutably. If evolution through natural selection is true, if species were not created fixed but evolve continuously through the gradual change of populations, then there is no special essence defining species. There is only a population in continuous genealogical flux, a gradual shift in genetic frequencies, transformation across generations. Boundaries between species are human conventions, classification tools used to organise continuous diversity, not realities residing in things themselves. An organism is not a member of a species because it realises a pre-existing essence; it is a member because it occupies a place in a genealogical continuity that we, modern observers, have decided to classify as belonging to a unit called species.

This did not eliminate essentialism, it merely relocated it ingeniously. Instead of seeking a static species essence, one began seeking an adaptative function essence: natural selection "chooses", and here teleological language returns, the fittest, the most adapted. That is, it selects organisms whose structure renders them adapted to the environment in a particular way. Essence transmigrated once more: it ceased to be form and became function; it ceased to be static and became dynamically oriented towards the future. Yet the fundamental metaphysical pattern persists: there is something immobile, fixed, unchanging in a radical sense beneath the shifting surface, this time not a Platonising form, but an adaptive function.

Kripke, in the 1980s, gave fresh impetus to this essentialism via exclusively semantic and logical routes. He argued, from the analysis of proper names and natural kind terms in counterfactual propositions, that such names possess a fixed reference based upon an "essence": a constellation of properties making that thing precisely that thing. A diamond is a diamond because it is carbon crystallised in a specific tetrahedral configuration. A whale is a whale because it possesses a specific biological structure (aquatic mammal, pulmonary respiration, etc.). Essence is no longer merely the property we observe in the object; it is that which explains how the name maintains fixed reference and how it manages to point to that particular object.

This argument offers philosophical comfort: there is something fixed and determined in the relation between word and world, a semantic anchor that is no mere social convention. But it creates a profound problem: essentialism returns through the back door, now in more sophisticated garb. If there are essential properties grounding name reference, then there is something deep within things themselves, an ontological depth, that language can capture and communicate.

Here the position governing this book, the position emerging from the accumulation of twentieth-century scientific evidence and subsequent philosophical critique, refuses with precision and fullness this Kripkean conclusion. Properties we use to define, those supposedly functioning as fundamental essences, are always relative to specific investigative contexts, always approximate, always revisable as new knowledge emerges or material circumstances change. It is not because language is fundamentally deficient or limited, it is because material reality contains no essences of the type the philosophical tradition sought to discover and fix. What changed fundamentally in the twentieth century is that we learned experimentally that what seemed essential, immobile, necessary, is actually contingent: every property can be different under different circumstances, was different in other cosmological epochs, will be different when unoccurred circumstances combine. Essence, therefore, is merely that which we have not yet managed to lose, while we have not yet lost it, while the conditions sustaining it have not yet changed.

2.2. Essence as a Name Given to Equilibrium

Essence is not an ontological property, it is not a thing existing in the material world or in a deep layer of reality independent of our mode of knowing. It is a symbolic effect, a linguistic phenomenon, a product of how we describe, name, fix, and conceptualise what we observe. When we fix our gaze upon an object during a period of observation, a crystal in a saturated solution, a star mid-way through its long life of a billion years, an organism in full biological maturity, in a state of apparent relative stability, we perform a specific and peculiar symbolic operation: we name that stable state as essence, we retroject the fixedness and permanence observed in this moment into the distant past (creating a narrative that "it was always thus"), we declare "this is what the thing truly is, this is its fundamental nature, this remains constant while all else changes". It is an act of language, of conceptualisation, of symbolic fixation.

Yet the present state is radically contingent, it is the outcome of a specific history that could have been entirely different in almost every detail. A crystal is cubic because the chemical and physical conditions of supersaturation, solute concentration, temperature, pH, evaporation speed, produced cubicity as a geometric configuration. Had solution concentration been marginally different, had temperature fluctuated at a critical moment during nucleation, had an exogenous particle entered a different medium of transformation, the crystal would be tetragonal instead of cubic, or rhombohedral, or completely amorphous (lacking crystalline structure). A living organism possesses this particular genotype, this specific sequence of three billion nucleotides, because this genealogical lineage underwent this particular sequence of mutations, in this order, within these geographically isolated populations. It would possess a radically different genotype had mutations been different, or occurred in a different order, or had populations remained geographically connected.

Nothing in this result is necessary. The material history that produced it could have taken different bifurcations at almost any point.

The operation of retrojecting fixedness is pure symbolic operation, it is an operation occurring within the domain of the symbolic, in the regime of language, in the manner we, as knowers, fix and name. It consists of observing what persists at a specific temporal scale, the scale we elect to observe, corresponding to our lives, our generations, our instruments, and transforming that relative persistence into an essential property, as though it were a property of the object itself. This operation is indispensable for any practice: we need it to communicate meanings, to allow the name "salt crystal" to refer always to the same type of thing, to classify organisms stably, to find tomorrow what we sought today. Yet it conceals a radical truth: observed persistence is always relative, relative to our scale of observation (hours, years, centuries), relative to our measurement instruments (what we can see, measure, record), relative to our epistemic and practical interests (what matters to us to know about this). Essence is a name, a word, a designation we give to the conformity of perseverance under specific observation, it is not a property we discover inhabiting the interior of objects.

Everything we observe in "equilibrium" is actually in a transitory quasi-equilibrium, an equilibrium that is always local, always temporary, always preserved only for as long as external constraints remain within a specific range. The crystal is not permanent, it dissolves if the solution undergoes a change in temperature or pH, fractures if subjected to mechanical pressure, ages microscopically if ultraviolet radiation bombards it over centuries. The star is not eternal, it consumes nuclear fuel in an irrevocable process, its life finite on a cosmic scale measured in billions of years before dying as a red giant, white dwarf, or another form. The organism is not fixed, it undergoes spontaneous mutations in every generation, ages through the accumulation of cellular damage, dies when the processes sustaining it cease. The illusion of permanence emerges from the radical disparity between our temporal scale of observation (the duration of our life, our civilisation) and the scales that truly determine the history of each thing.

We observe a crystal for hours or days, and across that extremely short duration it does not change visibly in form, impurities have not migrated significantly, structural defects have not expanded. We observe a star through generations of astronomers recording position, brightness, millennia, and across that duration it persists in a relatively stable form. We observe an organism for decades (a human lifespan), and across that duration it maintains general form and recognisable function despite continuous cellular change. Yet all these scales, hours, millennia, decades, are trivial compared to the scales truly determining history: the crystal was formed millions of years ago through complex geological transformations; the star was born a billion years ago from the gravitational collapse of a nebula and will collapse further in the future; the organism is the outcome of four billion years of evolution before arriving at any present form.

Essence, within this scheme, is the name we give to that which persists while we observe. This is literally all it is, nothing more, nothing less. Persistence is relative because it is always relative: relative to our observation scales, to the instruments we construct to measure, to the epistemic and practical interests guiding us. This is not relativism, there is a critical difference between "relativity" (the observer depends on a reference frame, yet invariant laws hold across reference frames) and "relativism" (everything is arbitrary according to opinion). It is the recognition that observed fixedness is perspectival: fixedness from a specific observation viewpoint, and only for as long as that viewpoint (and the constraints sustaining it) holds.

Naming by essence conceals simultaneously three dimensions of the reality it names. First dimension: it conceals the history that produced that form. When we declare that a diamond is essentially "carbon in a specific tetrahedral configuration" (the crystallographic definition), we focus entirely on present form as a final state, ignoring completely the processes that produced it, millions of years of variable pressure and temperature, chemical reactions, transformations through multiple crystalline phases (graphite, carbonado, intermediate forms), processes of material reconfiguration before arriving at the structure we observe. History, the becoming that produced, vanishes in the naming, subsumed by the artificial eternity of essence.

Second dimension: it conceals the instability persisting continuously within the appearance of stability. A crystal is filled with chemical impurities, crystalline structural defects, dislocations permitting certain movements, vacancies permitting gradual atomic diffusion, contaminations altering electronic properties. A star possesses interior turbulence, layer convection, dynamic instabilities creating detectable oscillations (brightness variations astronomers measure). An organism is under permanent biochemical stress: metabolism functions far from thermodynamic equilibrium (this is what distinguishes it from dead matter), immune systems combat pathogens continuously, cellular signalling competes for scarce resources, senescence processes begin at birth. None of this, none of this instability, is visible in the simple declaration "this is the essence".

Third dimension: it conceals the radical contingency of the entire outcome. This could have been very different, not as counterfactual fiction, but as material reality. Under marginally different initial conditions during crystallisation, a completely different form would arise. Under a different selective environment during evolution, an entirely other morphology would emerge. The necessity we feel, the sense that "this absolutely had to be this way", is retrograde projection: projecting onto the contingent past the appearance of necessity that the present (which has already occurred, which is already fixed) possesses.

In calling the present state "essence", we create a profound illusion that something fixed, determined, necessary exists inside things, when in truth what exists is contingency temporarily stabilised, frozen into a particular configuration only for as long as specific constraints hold. Essentialist language is extraordinarily comfortable: it offers immediate taxonomic clarity, permits stable reference (finding the same object tomorrow under the same name), functions as a communication tool. Yet it is deceptive at the ontological level: it projects fixedness and necessity where there is only relative persistence, where there is only contingency that has not yet changed.

If essence is a retrospective effect of fixation, if it is a symbolic operation freezing what we observe in an instant of observation, then form is not determined by essence. It is the direct opposite: form is that which produces the "appearance" of essence. The form we observe is the result of material processes arriving at a provisional quasi-equilibrium, maintaining relative persistence only for as long as chosen observation scales remain adequate, and only for as long as the constraints that produced it remain present in the current configuration. Calling this "essence" is merely registering nominally that relative persistence occurred, that something remained approximately constant while we observed within our limited temporal window.

This inversion is decisive: essence does not explain form. Form explains the illusion of essence. Form is what it is, material configuration, state of a system, and we call "essence" the pattern that form maintains while we observe. When form changes (and eventually it changes), the essence we proclaimed discovers itself as never having been essence, it was merely a name given to contingent persistence that has now ceased.

This fundamental realisation radically reorients the entire discourse on forms and natures. It ceases to be a metaphysical search for depth (what is the hidden essence explaining and grounding this form?). It becomes instead systematic empirical diagnosis: what are the specific material conditions that produced these particular configurations, what is the temporal history that caused them to emerge in this way and not another, what are the dynamics sustaining them continuously, what are the instabilities pulsating beneath the appearance of order and stability. Form is not the realisation of an essence preformed on some higher level awaiting actualisation. Form is a contingent event, a material irruption of configurations combining in this moment under these constraints, persisting for as long as these constraints hold.

2.3. Law, Description, and Repetition: What Regularity Does Not Prove

We observe that nature possesses deep and seemingly inviolable regularities. Gold does not oxidise spontaneously when exposed to dry air at room temperature, it behaves consistently thus, reliable, predictable. Ice floats on water, an anomalous, repeatable behaviour revealing different density in solid state compared to liquid. Planets orbit in predictable orbits, calculable with extraordinary precision, repeating in identifiable cycles (Martian year, Venusian period). Historically, from the ancients to modern classical physics, this observation was interpreted as decisive proof: there are "laws" that "govern" nature, immutable rules forcing behaviour, and the task of all science is to discover these hidden laws, to reveal the secret code keeping the universe running.

Yet regularity does not prove determinism, it does not prove there is a forcing law, that something internal to objects "forces" behaviour. It proves only this: under repeated conditions, similar results consistently occur. This is radically compatible with contingency: on each specific individual occasion, the outcome is contingent, dependent on specific initial conditions, present energy configuration, local interactions. Yet because conditions (temperature, pressure, chemical composition) possess a similar pattern (gold molecules behave like other gold molecules because they share similar atomic properties, water freezing cycles repeat because phase change processes repeat), outcomes exhibit a similar pattern. Law is not that which forces the outcome, it is precisely the description of the pattern emerging, regularly, when similar conditions encounter and combine similarly.

A physical law is a description of pattern, not a cause of pattern. This is true even if it seems obvious, and the evidence that it seems obvious is a measure of how completely this confusion has naturalised in our language. When classical Newtonian mechanics formulates $F = ma$ (force equals mass times acceleration), it describes an empirical relational pattern holding consistently: whenever force is applied to a mass (in a non-relativistic, non-quantum regime, outside extreme gravitational fields), the resulting acceleration follows a specific proportion to applied force and is inversely proportional to object mass. It is a repeating relationship, true across a vast number of cases. Yet the law does not explain why this is so, why nature behaves in this specific way rather than another. It merely describes that it is so.

Law describes pattern; law does not cause pattern. This is crucial, and frequently confused, because the confusion has deep roots in language itself. When we say in ordinary language "gravity makes planets orbit", we commit a semantic error: gravity does not "make" anything, it does not act as an agent. What actually occurs is that a body's mass produces curvature in the space-time continuum around it (this is the content of Einstein's general relativity), and in that curved space-time, a moving object (the planet) follows a geodesic, the path of least (curved) distance, and that geodesic takes the form of an elliptical orbit. This is what occurs, this is the physical process. The law of gravitation (the field equation) describes how mass distribution curves space-time; it does not "force" an orbit to exist, does not "compel" a planet to obey. The orbit is a necessary geometric consequence of following a geodesic in curved space-time.

Confusing description with causality opens a direct door to essentialism: it leads to thinking that law "forces" form to be as it is, that law is a deep hidden cause determining everything, governing the universe like an invisible sovereign. Yet law is merely observed regularity, identified and described pattern, the manner in which things recurrently occur under similar conditions, not an invisible agency dragging the future, not a hidden power ordering events.

This is particularly important when considering different scales and regimes in which the same object manifests. The same thing, the same crystal, the same planet, the same organism, behaves differently at different scales because different processes dominate at different scales. The law describing a planet in classical Newtonian orbit differs from the law describing that same planet in an extreme relativistic regime near a black hole because relativistic processes that were negligible become dominant. The law describing an isolated atom's behaviour at the quantum scale differs from the law describing a gas of many atoms at the statistical thermal scale because statistical properties emerge from aggregation. This does not mean nature changes essence, mysteriously obeying new and different laws like a chameleon changing colour. It means different mathematical descriptions are appropriate in different operating regimes. Description is regime-dependent because observable behaviour is regime-dependent, because different processes dominate dynamics at different scales.

Direct consequence: we cannot say the law of gravity "forces" the planet to orbit necessarily, such that it could do nothing else. We can only say that, given specific initial conditions (current position, current velocity), gravitation (described by Einstein's field equation) produces an orbit of a certain geometrically necessary form, had initial conditions differed (planet 1 AU closer, or 1 AU further), the orbit would be substantially different. Law does not determine initial conditions, this is what matters. Law does not determine the starting point; only what unfolds from the starting point when law operates. Law does not govern the universe in the sense of coercing it, it describes. Law does not force behaviour, it reports observed regularity.

Nature does not execute an implicit cosmic "plan" within laws as though interpreting instructions. Nature merely produces conditions, specific material conditions, specific energy states, specific dynamic configurations, and when similar conditions encounter and combine similarly, similar results emerge as necessary consequences of that combination. This is the foundation of all empirical science: being able to perform an experiment twice under conditions as identical as possible (same starting point, same forces, same restrictions) and obtain an equivalent result. Repetition is possible because nature is sufficiently regular in certain dynamic regimes to permit recognisable and predictable patterns.

Yet this does not mean there exists a prior "model" or transcendent "plan" that nature realises, as though an a priori invisible mould, a Platonic form, existed which every empirical realisation fulfils or approximates. It means only that nature is sufficiently stable in certain specific regimes to permit predictable patterns. But in other regimes, very near critical phase transitions where a system bifurcates entirely, very near deterministic chaos where stable systems become aperiodic, repetition breaks down spectacularly. Same initial conditions, measured with precision considered identical in a contemporary laboratory, produce dramatically different results because the system is hypersensitive to detail, overly sensitive to perturbations we cannot measure with sufficient precision, to thermal and quantum fluctuations we cannot control.

Law describes where the system is relatively insensitive to variation, a regime where small differences in initial conditions produce only small differences in observed final results. Yet there are regimes where such insensitivity ceases completely and the system enters a regime of maximum sensitivity to detail. Local determinism, predictability, the very possibility of universally valid law, all this is a local conquest, regime-dependent, a conditional expression of stability within a limited and specific domain, not a fundamental universal property characterising material reality in its totality or deep essence.

The repetition of patterns, the circumstance that similar conditions produce similar results, requires no prior invisible model for nature to realise. It requires only this: when similar conditions occur again, physical processes (which do not change, which are the same) process those conditions identically, producing similar results. A law is valid when it accurately describes this behaviour in that regime. When regime changes, when we exit the domain of validity (particles moving very fast, very low temperatures, very high densities), law ceases to describe accurately. Not because nature violated the law, because the law never applied to that new regime.

2.4. From Essence to Instability

The philosophical history of essentialism is a history of defence against change, against fluidity, against transience. It is a history of fear, fear that if nothing is fixed, nothing can be known; if everything changes, nothing possesses permanent value; if everything is transitory, the search for truth is futile. Plato required Forms, eternal, immobile, perfect realities beyond time, because the material world changes continuously: grows and ages, becomes and vanishes, ever unstable and eternally transitory. If everything we observe in the sensible world changes incessantly, how is there knowledge? How do we know something with certainty if that about which we supposedly know is perpetually in flux, ever transforming? The Form offered a reassuring answer: knowledge reaches that which truly does not change, that which persists eternally, the immutable structure beneath all contingent surface transformation.

Aristotle rejected the Platonic Form, it was ontologically overloaded, multiplying entities unnecessarily, yet preserved the fundamental necessity: there must be something immobile within movement, something unvarying within variation. Immanent form, essence, the formal principle remaining unchanged while all else material changes continuously. This offered scientific knowledge without metaphysical hypertrophy: essence resides in the natural object itself, not in a separate realm of eternal Forms. It is here, in this thing, present in matter.

Kant, eighteen centuries later, faced a similar problem in a new key. The empirical world is diverse, multiple, mutable, how is universal scientific knowledge possible? If sensory experience is always particular and contingent, how do we account for universal laws of physics holding for all possible experience? Kant displaced the ground to the interior: a priori categories of the mind, knowledge structures framing all possible experience, not because nature in itself possesses them, but because the structures of the knowing intellect impose them. There is something immobile, fixed: not in things in themselves (which remain unknowable), but in the transcendental apparatus knowing them. Necessity lies in the knowing mind, not the known object.

In every instance, Plato proposing Forms, Aristotle proposing immanent essence, Kant proposing a priori categories, essentialism is a response to a deep fear never fully verbalised. The fear: if nothing is fixed, how do we know anything with certainty? If everything changes continuously, how do we act rationally? If everything is contingent, how do we construct knowledge deserving of the name? Essence is always proposed as an anchor, that which changes not at all, that which remains immobile, that around which all else circulates unstably like satellites in orbit around a fixed sun.

Yet this defence, this millenary project of seeking and fixing essences, reveals itself in the modern era as built upon a fundamental illusion. We discovered, especially through twentieth-century quantum mechanics, non-equilibrium thermodynamics, and chaos theory, that there is no anchor, there is nothing fixed hidden beneath the shifting surface of the sensible world. Everything is in movement, in permanent reconfiguration, in an open state that permits no ultimate foundation. Essentialism is a hope for a stable, ordered, grounded reality, a hope that material reality systemically defeats and contradicts.

Let us take a careful inventory of what would seem most "essential", most absolutely impossible to lose without leaving the entire thing no longer what it is. Take the identity of elementary particles, would this not be defining essence if anything were? What is more essential to an electron than being an electron, possessing this specific electric charge ($-1$ in fundamental units), this specific rest mass, this specific intrinsic spin ($1/2$)? Yet quantum mechanics discloses that particles possess no fixed identity in the classical sense, they possess only probability amplitudes, wavefunctions describing possibilities. Prior to interaction or measurement, there is no defined electron, no fixed properties, only a spread amplitude of possibility. Identity and specific properties emerge only in interaction, in wavefunction collapse, in the encounter with a specific measuring apparatus.

The chemical composition of elements? Elements transmute in nuclear reactions, gold transmutes into lead through natural radioactivity, exactly as alchemists desired, only not through human intentional art but as a spontaneous process of nature. The form of living organisms? They evolve continuously, vary in response to environment, weaken or strengthen under selective pressure, transform across generations. The geometry of cosmic bodies? Gravity deforms them continuously, orbital motion alters form over time, collisions reconfigure them radically. Matter itself as a category? Antimatter exists, symmetrical and opposite; energy can convert into matter and matter into energy according to Einstein's mass-energy equivalence.

Nothing is an exception to this universal change. Nothing persists in a fixed, immobile form. Everything is subject to change, not as an accident or secondary property, but as a fundamental mode of being. Instability is no special or anomalous regime, no flaw in cosmic functioning, no exception proving the rule. It is a constitutive regime, the manner in which matter fundamentally exists and operates. What persists, what we still manage to call "relatively stable" or "enduring", is merely contingency holding under specific conditions that have not yet changed, which will eventually change.

This recognition, that there is no anchor, that everything is subject to instability, that change is the normal and constitutive mode of existence, is absolutely foundational, and cannot be understated, for everything that follows in this book and investigation. If form has no essence fixing it ontologically, if essence is a symbolic effect of retrospective fixation, then form is an event. It is not the realisation of a pre-existing plan, not the execution of prior cosmic design or intention, not the actualisation of latent possibility contained in a transcendent foundation. Form is that which emerges when specific material constraints combine in a specific manner, persisting for as long as those constraints continue to combine, vanishing or transforming entirely when constraints change, bifurcate, or cease.

A form's relative persistence is always contingent, not contingent in the sense of our epistemic ignorance (we know no better, though in itself it were necessary), but contingent as a constitutive property of the material real. Form persists relatively, not absolutely, because material conditions producing it still combine similarly, yet those combinations of conditions can always change, vanish, or reconfigure by bifurcating in new directions. Change of form is no deviation from immobile essence, no corruption of an original state of purity, no ageing or degradation in an inevitable direction towards death. It is the normal mode of existence, the way matter exists, continuous reorganisation, permanent reconfiguration.

The book opening here, the program of investigation governing this writing, unfolds the cascading consequences of this recognition: if forms are contingent, then the co-emergence of material body and energy field is no realisation of a cosmic plan or universal telos, but a permanent adjustment between processes possessing their own constraints, incomplete-nesses, openings. If forms are transitory, then order is not a telos, not a finality towards which nature tends or is oriented, but a provisional conformity to material constraints that can change. If forms change continuously, then time is no inert dimension in which events occur as on a static canvas, but a process of continuous material reconfiguration, and within that material reconfiguration possibility emerges that was not there before, an uncontained future opens.

Essence does not ground form; it registers nominally a relative persistence.

3. Universal Transience and Ungrounded Persistence

3.1. Instability Across All Scales

Everything assuming form in the universe is subject to permanent reconfiguration. This is no metaphysical principle nor generic philosophical thesis, it is a conclusion derived from systematic observation across multiple physical scales. From the quantum domain to cosmological systems, matter does not exist in a fixed, determined, essential state. It exists in a state of continuous transience, constrained not by an immutable essence, but by material compatibilities that change over time.

At the quantum level, indetermination is not ignorance, it is a property of the real. A quantum particle possesses no defined position prior to measurement; it possesses only a spectrum of position potentialities, weighted by a wavefunction. What the orthodox interpretation of quantum mechanics forces us to recognise is that there is no property "in itself" awaiting revelation. There are only compatibility relations: a horizontal spin measurement renders a vertical spin measurement incompatible, not because the first "revealed" a property that "concealed" the second, but because these properties are mutually exclusive within the formalism. The quantum system is in itself indeterminate until coupling with a measuring apparatus. This is crucial: it is not that we cannot know, it is that there is nothing to know at that level of description. Matter at the quantum level is "unstable" not in the sense of continuous change from one well-defined state to another, but in the sense of fundamental non-definition. The very notion of "property" requires reformulation: there are only potentialities, compatibility relations, incompatibilities structuring the space of possible interactions.

Ascending in scale to the chemical level, instability assumes a different yet equally penetrating form. A water molecule is stable under certain conditions (pressure, temperature, concentration), yet alter one of these conditions and the molecule decomposes. What stabilises the bond between oxygen and hydrogen is not an essence that "wants" to be water, it is an equilibrium between electromagnetic forces that, given certain parameters, converges on this configuration. Alter parameters and the equilibrium shifts. A chemical reaction seeming "slow" (a candle slowly burning) can, under sufficient pressure or temperature, become an explosion. A reaction cascade (reactions catalysing reactions catalysing further reactions) can lead to explosive amplification without advance warning. A small pH change can precipitate molecules that were in solution. A phase transition (water becoming ice) is a sudden reorganisation of the entire molecular structure in response to temperature change, form shifts from fluid to crystalline, not because the system "decided" to become solid, but because compatibility between water atoms changed, rendering a crystalline configuration more stable than the preceding form. All this demonstrates that apparent chemical "stability" is a perspectival illusion: the system is ever on the verge of transitions, ever under pressure of change, ever contingent upon the conditions sustaining it.

At the astrophysical scale, planetary orbits seeming eternal, one of the classic images of stability and necessity, reveal themselves as chaotically unstable across sufficiently long time scales. The solar system is stable for a few billion years (a scale compatible with biological life on the planet), yet eventually disorganises: a planet is ejected by an encounter with a foreign body, orbits enter chaotic resonance, the system as a whole fragments and reorganises into a new configuration incompatible with life as we know it. Nothing is eternal, everything possesses a finite lifespan, after which known forms reorganise completely.

At the geological and thermodynamic scale, instability assumes a more persistent yet equally fundamental character. Earth seems permanent, and is permanent compared to human life, yet is not on a geological scale. Plate tectonics move continents; continental shapes change radically over hundreds of millions of years. The supercontinent Pangaea existing ~250 million years ago fragmented into continents we would not recognise on an ancient planetary map. Erosion wears down mountains appearing immobile, the Himalayas grow by only a few hundred metres per year through plate collision, yet erosion removes mountains radically faster on scales of tens of millions of years. Climate fluctuates between glacial and warming periods on a scale of tens of thousands of years. The ocean shifts chemistry as sediments deposit and dissolve, altering salinity and pH across geological time. All these processes, varied in mechanism and scale, are governed by a fundamental thermodynamic principle: entropy ever increases, all structure is susceptible to degradation, all organisation susceptible to dispersion. This is no vague threat, it is a material engine constraining every configuration towards eventual disorganisation.

The concept of dissipative structure, developed by Ilya Prigogine, is fundamental here for comprehending how order can emerge and persist within this universal regime of degradation. A dissipative structure is a system maintaining order (internal organisation, pattern, differentiation) so long as it imports energy from the exterior, yet this order is metastable, depending completely on continuous energy flow. When energy flow ceases, the structure disorganises, entropy wins, everything disperses into a state of thermal equilibrium. Living cells, complex organisms, ecosystems, landscapes, hurricanes, space plasma jets, stars, all these are dissipative structures: organisation persisting only while nourished by a continuous influx of external energy.

Prigogine demonstrated that far from thermodynamic equilibrium, new structures can emerge, organisation patterns that did not exist near equilibrium. This was a conceptually revolutionary discovery because it disproved a deep assumption: that order (organisation, pattern) is a rare exception requiring special explanation, while disorder is the natural state towards which everything tends. Prigogine showed that the relationship is inverted: far from equilibrium, systems can organise spontaneously into increasingly complex structures if energy influx is sufficient. Order is no exception, it is a consequence of thermodynamic dynamics far from equilibrium. A living cell is no anomaly violating thermodynamics, it is a system existing only because it imports energy (food) from the exterior, and this energy permits the system to organise in ways impossible at equilibrium.

The thermodynamic difference between organisation near equilibrium and far from equilibrium is radical. Near equilibrium, possible structures are only those minimising free energy (a stable state). Far from equilibrium, with permanent energy flow, extraordinarily more complex structures become possible because incoming energy permits the maintenance of gradients and differentiation patterns impossible otherwise. A temperature difference between two points, maintained by continuous energy influx, permits the emergence of convection (organised fluid movement). A food concentration maintained by continuous influx permits the emergence of an organised biochemical reaction network (metabolism). Without energy flow, that is, in an equilibrium regime, none of this exists. There is only homogeneous soup, uniform temperature, uniform concentrations. Order emerges precisely because non-uniformity is maintained by external influx.

Yet here it is crucial to distinguish two positions that may seem convergent yet diverge profoundly. Prigogine emphasises that dissipative structures emerge "spontaneously", order emerges far from equilibrium without requiring prior plan or intention, and the discovery is that this is a necessary consequence of thermodynamics. We retain the conclusion: order can emerge without a prior plan. We refuse the suggestion that there is any immanent intentionality or unified engine within these structures, or that order represents any kind of "triumph" or directed progression. Dissipative structures are material configurations persisting while compatible constraints hold. When constraints change, when energy flow shifts, when external temperature rises or falls, when chemical composition alters, the structure reorganises. There is no force that "wants" organisation, there is only material dynamics in response to changing compatibilities, and that dynamics is indifferent to outcomes.

Instability, therefore, is no special or anomalous regime, it is the constitutive regime of all material real. There is no scale at which we do not encounter fundamental transience. What persists (atoms, molecules, celestial bodies, organisms) persists only while specific conditions combine compatibly. Alter conditions and everything reconfigures.

3.2. Genealogy of Permanence and Becoming

The tension between fixedness and change traverses the entire history of Western philosophy, and its origin is the confrontation between Heraclitus and Parmenides at the dawn of Greek thought. Heraclitus insisted that everything flows, that change is constitutive of the real, that the river is never the same river because the water continues to change. Yet his successors rejected this conclusion as contrary to philosophy's most fundamental requirement: knowledge. If everything changes, how do we know anything? How can we speak of "this" if "this" is constantly transforming into "that"?

Parmenides answered this philosophical crisis with a radical conclusion: then change is not real. What is real is being, immobile, eternal, ungenerated, incorruptible. Becoming, change, is an illusion of the senses. True being is undifferentiated, eternal, outside time. This response established a pattern that would contaminate all Western metaphysics: the choice between two extremes, either everything is change (reductionism to becoming), or there is something immobile (essentialism denying change).

Neither side of this dichotomy describes the real, both describe fictions. There is no pure being, immobile, eternal (everything is subject to continuous material reconfiguration, as seen in 3.1). Yet there is also no pure amorphous, indeterminate becoming (there are regularities, patterns, material compatibilities constraining change and producing relative persistence). The true situation is more subtle: change is constitutive of the real, yet change is constrained, ordered, paced by specific material dynamics.

Henri Bergson offered a crucial contribution to rethinking this problem when he criticised the philosophical tradition for spatialising time. Western metaphysics, according to Bergson, treated time as a geometric dimension, a line on which past, present, and future points already exist, merely awaiting sequential revelation. Yet this falsifies the nature of time. Real time (duration, in his own words) is that which produces novelty irreducible to law, time is creative in the literal sense that it creates states uncontained in preceding conditions. Change is not an alteration of property in a previously determined state; it is the creation of a new state, genuinely new, non-deducible from the past.

This critique is penetrating and its lesson remains: time is truly creative, the future is no pre-determined copy of the present, change is no decoration upon a fundamentally deterministic process. We refuse the mechanism Bergson places as the engine of this creativity. Bergson postulates an "élan vital", a unified vital impulse traversing all life, constantly pushing matter into new configurations, responsible for increasing complexity and creativity. For Bergson, there is a single movement of the real towards growing complexity and differentiation.

This unified impulse cannot be accepted as an engine because it would reintroduce the essentialism and teleology we sought to avoid. Creativity comes from material frictions, from incompatibilities between constraints, from permanent reconfiguration in response to energetic pressures. There is no élan, there is only material dynamics. There is no unification, there are only local pattern compatibilities. Bergson retains creativity irreducible to law and refuses quantitative homogeneity; the position sustained here maintains this yet eliminates the vital unifier Bergson places at the centre.

Whitehead, Simondon, and Deleuze developed, in different contexts and vocabularies, a perspective deserving of inheritance and recalibration: that processuality is more fundamental than substance. The substantialist model, the idea that there are things with properties, is a surface model. The true foundation is process. Whitehead reformulated philosophy entirely around the category of "event" rather than "thing": what is real is not an object with properties, but a process of realisation involving prehension (reception of influences) and concrescence (convergence into unity).

Simondon formulated this with even greater precision: "there are no things, only individuations". A thing is not a ready-made entity existing simply, it is a process of individuating itself, differentiating from a background, acquiring gradual specification. The individual is always the outcome of a process, never the starting point. This revolutionises ontology: the true level of analysis is not the ready thing (the tree, the animal, the atom) but the process of differentiation producing the thing.

Deleuze insisted upon a variation of this perspective: becoming is not a continuous amorphous flow (this would merely be a sophisticated version of Bergsonian essentialism). Becoming is structured differentiation. Reality differentiates according to specific vectors, the virtual (a plane of potentialities) differentiates into actuality (a plane of concrete forms). This differentiation is not random; it follows lines of tension, compatibilities, attractions and repulsions inherent in the structure of differentiation.

This triple heritage, Whitehead's processuality, Simondon's individuation, Deleuze's differentiation, is received and reformulated. Form is no separate substance endowed with essence. Form is an emerging pattern of a material process persisting while the dynamics sustaining it continue to operate. Yet where Whitehead speaks of "resolution" (process naturally tending towards a certain equilibrium of prehension), and where Simondon speaks of "resolution" of pre-individual charge into consummated individuation, the position sustained here speaks of contingent persistence, form persists while constraints hold, not because it "resolves" into a final stable or naturally determined state.

The differentiations here are deep. Whitehead retains "prehension", a form of proto-conscious experience every entity occasions; this proto-experience is rejected here because it introduces semiotic projection into the pre-symbolic domain. Simondon places at the foundation a "pre-individual charge" that is an ontological stratum susceptible to resolution; the position sustained here places at the foundation an "excess", a dynamics without final resolution, ever in a state of reconfiguration, incapable of definitive stabilisation. Deleuze retains the "virtual" as a plane of potentialities ontologically real and distinct from the actual; the virtual is dissolved here into symbolic fiction, what exists are material compatibilities constraining change, not a metaphysical plane of potentialities.

Thus, the genealogy of permanence and becoming reveals itself as a tension between two complementary errors: essentialism denying change, and fluxism denying constraint. The truth lies between these extremes, not as a mediating tertium quid, but as the recognition that change is real and fundamental, that persistence is merely relative and contingent, that there is no substrate that does not change nor any change that is pure amorphy. Reality is constrained process, dynamics under specific material compatibilities, structured becoming rather than chaotic becoming or eternal being.

3.3. Stability as Scale Effect: Dissolution of Substrate

If everything is subject to change, then what do we understand by "stability"? The answer is: stability is a retrospective effect of observation scale. What we call "stable" is that which does not change on the time scale relevant to our observation.

An atom seems stable, and its stability is one of the most fascinating characteristics of matter. A gold nucleus is practically indestructible through ordinary chemical processes. This made gold a precious metal, because it does not oxidise, decay, or degrade like iron or copper. Yet "practically indestructible" is not "eternally stable". A gold nucleus undergoes radioactive decay, there is a probability that, spontaneously, the nucleus emits particles (alpha, beta, etc.) and transmutes into a different element. The time scale of this decay is gigantic, far larger than the age of the universe for certain isotopes, yet still finite. What safeguards the atom from collapse is a quantum regime different from what we would have if nothing operated, yet the fundamental point remains: even the "most stable" we know possesses a finite duration and is under permanent constraint. We call it "stable" merely because our observation scale (years, days, even millions of years) is trivial compared to the scale of nuclear decay. Shift the observation scale to a billion years and the "stable" becomes "slowly dissolving".

A diamond crystal exemplifies this principle with even greater clarity. The diamond is known to be one of the hardest, most stable, most permanent substances in nature. Historically, it was a symbol of eternity and immutability, "diamonds are forever", proclaims advertising. Yet the genealogy of a diamond demonstrates this perfectly: it is carbon subjected to extreme pressures and temperatures over millions of years, during that time it underwent countless reactions, deformations, material reconfigurations, before "crystallising" into the form we observe now. Present form is an effect of specific history, contingent upon particular conditions that occurred, not an eternal substrate that pre-existed. Most diamonds we know were formed within a very specific regime: between 150 and 200 kilometres depth in Earth's mantle, where temperature is between 1,000 and 1,200 degrees Celsius, and pressure is between 50 and 60 kilobars. This is a very precise requirement. Alter any of these parameters to a lower tier, depth reduces to 100 kilometres, temperature drops to 700 degrees, and what forms is not diamond, but graphite or another allotrope. Diamond is not "natural", it is the realisation of a very specific set of constraints.

And even now, "crystallised", diamond is slowly transforming: it is metastable, not stable. Under certain conditions of pressure and temperature (not as extreme as those of its birth, yet significant), diamond tends to convert into graphite, another form of carbon, less dense, less "beautiful", yet thermodynamically more stable on a scale of a billion years. The diamond you hold is eternal only on a scale of millions of years, the scale of human life. Yet on a scale of a billion years, even diamond decomposes, transforms, dissolves into a more stable form. Diamond also undergoes slow oxidation when in contact with air and water, a diamond exposed to weathering over a period of tens of millions of years can be progressively consumed by oxidation. It is no rapid process, the oxidation rate is extraordinarily slow, yet it is real. Diamond is no top of the ladder of material evolution, it is merely a provisional station on a trajectory of continuous transformation, a configuration persisting while specific constraints hold, which will transmute into something else as temperatures and pressures change, as the planet ages, and as geological processes reposition it in different zones.

A living organism offers an even more radical example of this substrate dissolution. An organism seems to be a stable unit, it possesses recognisable form, predictable behaviour, persistent identity distinguishing it from the environment. This appearance of stability is an illusion even deeper than that of diamond. An organism is a continuous flow of matter, it is not a container retaining substance, it is a process of permanent material reconfiguration. Molecules constituting it are constantly entering and exiting, replacing one another. Respiration is permanent exchange, each breath removes carbon dioxide from the interior (metabolic combustion product) and brings fresh oxygen from the exterior. Nutrition is the incorporation of exterior matter (food) and elimination of waste no longer compatible with the pattern. Cellular renewal is extraordinary: in an adult human, approximately 330 billion cells die and are replaced each day.

A human being is constituted of approximately 70% water, and that water is constantly being replaced. A study using isotopic tracers demonstrated that body water is completely replaced approximately every ten days. Red blood cells possess a lifespan of approximately 120 days, when they die, they are destroyed by the liver and haemoglobin recycled to manufacture new blood cells. Intestinal cells, facing a highly acidic and abrasive environment, are replaced every three to five days. Skin cells every two to four weeks. Even bone cells, appearing as permanent structures, are under continuous remodelling, there are cells (osteoclasts) constantly removing old bone and cells (osteoblasts) constantly constructing new bone. In an adult, the rate of bone remodelling is such that approximately 10% of bone mass is replaced each year. Over ten years, practically the entire skeleton has been replaced.

What persists is not matter, it is a pattern of reaction, organisation of processes, compatibility between functions maintaining living structure while energies flow through it. The organism is a true dissipative structure in the sense Prigogine described: it imports energy (food, respiration), exports entropy (waste, heat), and while this flow holds, structure persists. The organism's form, its size, general geometry, functional capacities, persists because processes sustaining it continue to function. Every cell dies within weeks or months, yet the pattern of cell types, the pattern of their connections, the pattern of signals between them, persists recognisably. It is a pattern of process, not material composition.

The organism's identity is an illusion of the same type as the identity of Heraclitus's river, not because matter changes (though it does), but because what we call "identity" is an organisation pattern, not a static composition. The pattern can persist while matter changes radically, the river possesses identity because water molecules continue flowing in a recognisable pattern, not because the same molecules remain. When metabolism ceases (death), the pattern disorganises almost immediately: without energy influx, entropy wins, molecules disperse, structures collapse. Proteins begin denaturing within hours. Cells disintegrate. Tissues rot as bacteria consume released matter. The organism's "identity" was merely a pattern of constraints maintaining order, when those constraints cease operating (because metabolic energy no longer flows), what we called "organism" vanishes, and all that remains is matter dispersed into decomposers and climate.

The difference with Bergsonian theory is decisive here. Bergson proposed that life possesses a "tendency" to organise itself, an élan vital constantly pushing against entropy, creating novelty and growing complexity. For Bergson, there is something at the heart of life rendering it tendentially creative, tendentially oriented towards growth. Yet what thermodynamics discloses is different: organisms possess no tendency towards anything, they possess only compatibility with energy flow. While energy enters, they organise. When energy ceases, they disorganise. There is no vital impulse, there is only a response to energy availability. The creativity, the growing complexity we observe in biological evolution, comes from no immanent tendency, it comes from response to natural selection of organisms managing to capture and utilise energy efficiently. There is no telos, no pre-oriented direction. There is only differential reproduction of organisms as they manage to survive and reproduce, and this, accumulated over generations, may seem like directed tendency, yet is merely the cumulative outcome of selection without orientation.

This reveals a profound truth concerning the ontological ground of all we call stable or permanent: there is no substrate that does not change. Across every scale, quantum, atomic, crystalline, biological, astrophysical, what we understand by "permanent" is merely "sufficiently persistent on the observation scale we choose". Permanence is perspectival, relative, contingent upon the choice of temporal horizon. Defeat this choice, expand the scale sufficiently, and everything reveals itself as transitory.

This conclusion defeats all substantialist metaphysics. Substantialist metaphysics rests upon a simple idea: there is something "below", a ground that does not change, around which all else changes. It may be called "indivisible atom" (like the ancient Atomists), "essential property" (like the Scholastics), "thing-in-itself" (like Kant), "transcendental subjectivity" (like German Idealism). The pattern is ever the same: there is something persisting unconditionally, and change is merely accidental modification of that permanent something.

Yet what we saw in 3.1 and have now explored in 3.3 renders this framework untenable. What exists is pattern across multiple scales, pattern persisting while specific conditions combine compatibly, vanishing or transmuting when conditions change. There is no deeper layer of immutability. The deeper we go (to the quantum level), the less definition we find, not more. Reality is no inverted pyramid with an essence peak at the bottom; it is a network of constraints across multiple scales, each dependent upon others, none fundamental.

3.4. From Instability to Forces: Threshold of Opening

Universal instability, the transience permeating every scale of reality, is not synonymous with chaos. This is a fatal confusion that must be dissipated. Instability means the permanent reconfiguration of matter in response to specific dynamics. Yet that reconfiguration is not amorphous, not random in the sense of being completely indeterminate. It possesses pattern, direction, regularity, not the regularity of immobility, but the regularity of paced change.

Deterministic chaos offers a paradigmatic example of this recognition. A system evolving according to deterministic laws (without randomness in any sense) can still be non-predictable because it is extraordinarily sensitive to initial condition detail. The famous "butterfly effect", the idea that a minuscule alteration in initial conditions (flapping butterfly wings in one city) can lead to radically different consequences (a storm in another city weeks later), is a manifestation of deterministic chaos. The system obeys precise laws; the system possesses no randomness; the system is nonetheless unpredictable because sensitivity to initial conditions is such that we can never know conditions with sufficient precision.

Yet even in this chaos there is no amorphy. Deterministic chaos possesses structure. The strange attractors describing the behaviour of chaotic systems possess fractal dimensionality, they are not simple points, not conventional lines or surfaces, but intermediate geometric structures between one and two dimensions. The pattern is invisible at first glance, yet it is there: the system's trajectory is non-predictable long-term, yet the trajectory is not random, it follows a path through the strange attractor, repeats infinitesimal patterns at multiple scales, remains confined to a specific region of phase space.

This means instability does not annul constraint, it merely renders constraint more refined, less obvious, more dependent on detail. Matter does not do what it wants, it does what the compatibility of constraints permits it to do. These constraints are multiple: energetic constraints (the first law of thermodynamics), entropy constraints (the second law), chemical compatibility constraints (covalent bonding happens only when electronic orbitals can hybridise), symmetry constraints (fundamental forces exist because certain symmetry groups are realised), topological constraints (the shape of a manifold constrains which geometries can inhabit it).

The notion of "opening" emerges precisely in this recognition. The universe is no closed system in which everything that can happen is already determined by initial conditions (this would be pure classical determinism). The universe is also no complete chaos where anything can happen (this would be unconstrained licence). The universe is an open system, open in the sense that the future is no mere replication of the past, that there is room for reconfiguration, that novelty can emerge.

Yet "open" is not "infinitely plastic". It is not "anything is possible". There are constraints. Matter is open within boundaries drawn by material compatibilities. This is the true function of opening: opening space for possibility, for contingency, for creativity, yet within specific material guardrails. The following chapters explore in detail how these constraints produce order; how this order is always relative, always contingent; how change is the normal mode of existence, not an accidental deviation from ideal stability.

Matter does not wait to be essential. Matter reorganises continuously in response to what forces it to change, energies traversing it, dynamics constraining it, frictions deforming it. And it is in these frictions, in these permanent reconfigurations, in these reorganisations that the forms emerge which we later observe, designate, and attempt to comprehend.

What this means is that forms we perceive as stable, a person, a mountain, a star, a crystal, are not realisations of pre-existing essences. They are effects of dynamics that have reached a point of relative equilibrium. They are the fruit of a contingent history, of compatibilities of constraints combining in a specific manner, of energies flowing through material processes. Every form possesses a genealogy, a past that produced it, and every form possesses a future, a trajectory of change that will transform it into something else. No form is final, none is essential, none is necessary.

This may seem an uncomfortable conclusion, the dissolution of substrate, the denial of foundation, the acceptance that everything is in permanent reconfiguration. Yet it offers compensation: recognising that there is no substrate to grasp onto means recognising also that there is genuine freedom for the new. Were form not contingent, were it the realisation of a necessary essence, the future would be a predetermined copy of the past. But because form is contingent, because it emerges from frictions and compatibilities not written in eternal stone, the future is genuinely open. Matter is no prisoner of essence. Matter is open to permanent reconfiguration.

This opening is that which permits all subsequent complexity: the emergence of order from dynamics, the persistence of form even in transience, the evolution of increasingly complex structures, the possibility of life and, eventually, consciousness. All this is possible precisely because matter is not fixed in essence, because it is open to change, because it is capable of permanent reconfiguration.

Closing

The stable is the unstable we have not yet watched change.
