The Intolerances of Scientific Explanation: 3 What Explanation Cannot Contain

Scientific explanation is among the most powerful achievements of human thought. It stabilises patterns, constrains possibility, and renders the world tractable. Across domains, it delivers prediction, control, and coordination at scales previously unimaginable.

And yet, wherever explanation succeeds most completely, something presses back.

This post is not an argument against explanation. It is an attempt to name, carefully and without polemic, what explanation cannot contain.

---

Explanation as Productive Constraint

To explain is not merely to describe; it is to constrain.

Every explanation performs an act of selection:

• it fixes a unit,

• privileges a level,

• establishes variables,

• and excludes relations that cannot be stabilised within the frame.

This exclusion is not a flaw. It is what makes explanation possible. Without it, explanation dissolves into an undifferentiated field.

But exclusion has consequences.

---

The Remainders of Explanation

Across the sciences we have traced, certain elements return with remarkable consistency:

• Meaning, in neuroscience.

• Agency, in artificial intelligence.

• Contingency, in evolutionary biology.

• Description itself, in quantum theory.

These are not gaps waiting to be filled. They are remainders — aspects of the relational field that do not survive the cut required for explanation.

They do not disappear. They return as discomfort, debate, resistance, and intolerance.

---

Why These Remainders Persist

The persistence of these remainders is not due to insufficient data or immature theory.

It is structural.

Meaning is relational and perspectival; explanation requires stabilisation.

Agency requires participation; explanation abstracts from participation.

Contingency resists inevitability; explanation favours necessity.

To contain these fully would be to abandon explanation itself.

---

The Error of Closure

The most common mistake made in response to these remainders is the insistence that nothing has been excluded.

This insistence appears in many forms:

• claims that meaning is “just” neural activity,

• claims that agency is “just” optimisation,

• claims that contingency is “just” ignorance,

• claims that description mirrors reality without remainder.

These moves are not clarifications. They are acts of closure — attempts to deny the cost of the explanatory cut.

It is here that intolerance emerges most sharply.

---

Intolerance as Signal

Intolerance arises when explanation is asked to do what it cannot:

• to exhaust the field it cuts into,

• to absorb relational excess without remainder,

• to replace perspective with mechanism.

Resistance, anger, and conceptual revolt are not pathologies in this context. They are signals — indications that the field exceeds the form.

To read them as errors is to misread the phenomenon.

---

Explanation Without Sovereignty

What emerges from this series is a view of explanation that is powerful but not sovereign.

Explanation:

• works,

• constrains,

• clarifies,

• and always leaves something out.

This is not a weakness to be repaired, but a condition to be acknowledged.

Scientific understanding advances not by eliminating these remainders, but by learning to live with them — by recognising where explanation must stop without mistaking that stopping point for failure.

---

A Relational Orientation

Seen relationally, explanation does not reveal a world independent of perspective. It actualises intelligibility from within a field of constrained possibility.

Meaning, agency, and contingency are not external to science. They are what science must continually negotiate, suppress, and encounter again as resistance.

The task is not to resolve this tension, but to remain attentive to it.

---

What Remains

What explanation cannot contain is not noise or illusion. It is the relational field itself — the conditions under which explanation becomes possible, and beyond which it cannot go.

To recognise this is not to retreat from science, but to understand its power more clearly.

The cut will be made again.

The remainder will return.

And the work, each time, will be to read that return with care.

The Intolerances of Scientific Explanation: 2 Artificial Intelligence and the Intolerance of Agency

Artificial intelligence does not introduce a new problem.
It exposes an old one without the protective ambiguities of biology.

Where neuroscience still deals with organisms — embodied, historical, affect-laden — artificial intelligence presents behaviour without life, optimisation without experience, and performance without perspective. What was previously contested now becomes stark.

The discomfort that surrounds AI is therefore not primarily ethical, social, or speculative. It is ontological.

---

Behaviour Without a Subject

Artificial intelligence stabilises a particularly severe explanatory cut:

• behaviour is produced by optimisation,

• success is defined by performance metrics,

• learning is adjustment within a predefined space of possibility.

From within this frame, AI systems can outperform humans, adapt to environments, and generate outputs indistinguishable from intentional action.

What they do not do is act.

There is no perspective from which the behaviour occurs. No stake, no concern, no situated point of view. The system performs, but it does not participate.

This absence is not accidental. It is required.

---

Optimisation as Explanatory Closure

AI explanation is at its most confident when it is most minimal:

• inputs,

• objectives,

• loss functions,

• updates.

Nothing else is needed. No meaning, no intention, no understanding.

This is not a failure of AI. It is its triumph. The system works precisely because agency has been excluded from the explanatory frame.

But this exclusion carries a cost.

---

The Return of Agency

The debates that surround AI are strikingly repetitive:

• Is it intelligent?

• Does it understand?

• Can it intend?

• Is it responsible?

• Is it conscious?

These questions are often dismissed as category errors — as anthropomorphic confusion or misplaced intuition. But their persistence suggests something else.

Agency is not being mistakenly projected. It is being structurally withheld, and its absence is felt.

The discomfort does not arise because AI is misunderstood, but because behaviour now appears without construal.

---

Agency as Relational Phenomenon

Agency is not a property that can be added to a system once performance is sufficient.

It is:

• perspectival,

• situated,

• historically and socially constituted,

• bound to participation in a field of significance.

Agency exists only where actions matter to the one acting — where outcomes are not merely optimised, but owned.

AI systems do not lack agency because they are insufficiently complex. They lack it because they are not sites of construal.

---

Why the Intolerance Intensifies

In neuroscience, meaning resisted reduction while remaining attached to living bodies. In AI, that attachment is gone.

The same explanatory cut now produces a sharper effect:

• behaviour is flawless,

• performance is measurable,

• explanation is complete,

• and yet something is unmistakably missing.

This generates an intolerance of agency — a refusal to accept that behaviour alone exhausts action.

The insistence that “nothing is missing” is precisely what provokes resistance.

---

Responsibility Without Ownership

This intolerance becomes acute around responsibility:

• Who is accountable?

• Who decides?

• Who acts?

The answers cannot be found inside the system. Responsibility does not belong to optimisation procedures.

The attempt to locate agency where there is only execution produces anxiety — not because the system is dangerous, but because the explanatory cut has removed the very locus where responsibility normally resides.

---

A Familiar Structure, Now Exposed

Once again, the same pattern appears:

1. A field of constrained possibility (action within a world of significance).

2. A necessary explanatory cut (optimisation and performance).

3. Extraordinary success.

4. Suppression of construal.

5. Intolerance and unease.

AI does not create this structure. It reveals it without distraction.

---

What AI Forces Us to See

Artificial intelligence confronts scientific explanation with its own limit:

• Explanation can produce behaviour.

• It cannot produce participation.

• It can optimise outcomes.

• It cannot generate perspective.

The discomfort surrounding AI is not a failure to understand machines. It is a recognition — often unarticulated — that agency cannot be engineered by optimisation alone.

---

Closing the Loop

From quantum theory to evolutionary biology, from neuroscience to artificial intelligence, the same cut has been repeated:

• stabilise explanation,

• suppress relational excess,

• provoke resistance.

Artificial intelligence is simply the point at which the absence becomes impossible to ignore.

What remains is not to resolve this tension, but to learn how to read it — not as error, not as fear, but as a structural signal of what explanation cannot contain.

The Intolerances of Scientific Explanation: 1 Neuroscience and the Intolerance of Meaning

Neuroscience is one of the great successes of modern science. Its explanatory power is undeniable: neural circuits can be mapped, manipulated, modelled, and predicted with increasing precision. Behaviour can be altered by intervention; capacities can be impaired, restored, or reshaped. Few domains demonstrate more clearly what mechanistic explanation can achieve.

And yet, no scientific field generates more persistent unease about what has been left out.

This post is not concerned with whether neuroscience is correct. It is concerned with what neuroscience must exclude in order to be explanatory at all, and with the form of resistance that exclusion inevitably provokes.

---

Mechanistic Explanation Without Apology

Neuroscience proceeds by stabilising a particular explanatory cut:

• neural activity is taken as causally sufficient,

• cognition is treated as neural process,

• behaviour is explained through circuits, signals, and dynamics.

This cut is not optional. Without it, there is no neuroscience. Mechanisms must be isolable; variables must be measurable; causal pathways must be traceable.

The success of the field depends precisely on this restriction.

---

The Explanatory Cut

To make neural explanation work, something must be bracketed.

Experience — what it is like to perceive, to feel, to intend, to understand — is not denied, but it is repositioned:

• as report,

• as correlate,

• as output,

• as side-effect.

Meaning does not disappear, but it is displaced. It becomes something to be explained away, or explained indirectly, once the real causal work has been done elsewhere.

This is not an oversight. It is the cost of the cut.

---

Meaning as Relational Excess

Meaning is not a localisable object.

It is not contained in a neuron, a region, or a firing pattern. It is:

• contextual,

• perspectival,

• historically situated,

• relationally constituted.

Meaning arises only within a field of relations — between organism and environment, intention and action, history and anticipation. It is not a thing that can be isolated without being transformed.

For mechanistic neuroscience, this makes meaning structurally inconvenient.

---

The Return of the Suppressed

The persistence of certain debates in neuroscience is therefore unsurprising:

• the “hard problem” of consciousness,

• the explanatory gap,

• the unease surrounding reduction,

• the intuition that something essential has been missed.

These are not signs of ignorance or mystification. They are pressure points — places where relational excess presses back against a mechanistic cut that cannot accommodate it.

The more complete the neural account becomes, the sharper the discomfort can feel.

---

Intolerance, Not Failure

It is tempting to interpret this discomfort as resistance to science itself. That interpretation is mistaken.

What is resisted is not explanation, but closure: the implication that mechanistic sufficiency exhausts intelligibility.

The intolerance that appears here is an intolerance of meaning being treated as dispensable — as something that can be fully replaced by causal description without remainder.

This intolerance is not an error. It is structurally generated.

---

Why the Debate Cannot End

No amount of additional data will eliminate this tension.

That is not because neuroscience is incomplete, but because meaning does not belong to the same explanatory register as mechanism. To insist that it must be fully absorbed is to misunderstand what the explanatory cut accomplishes — and what it necessarily excludes.

Neuroscience can explain how neural activity constrains experience. It cannot turn meaning into a mechanism without destroying what makes it meaning.

---

A Relational Diagnosis

From a relational perspective, neuroscience reveals the familiar pattern:

1. A field of constrained possibility (organism–world relations).

2. A necessary explanatory cut (neural mechanism).

3. Extraordinary formal success.

4. Suppression of relational meaning.

5. Persistent resistance and unease.

This is not a problem to be solved. It is a structure to be recognised.

---

Toward Artificial Intelligence

This matters because neuroscience is not the end of the story.

When mechanistic explanation is no longer applied to organisms, but to engineered systems — when optimisation replaces adaptation and design replaces history — the same intolerance reappears, amplified.

If meaning already resists reduction in brains, what happens when behaviour is generated without lived perspective at all?

That is where the next cut will be examined.

The Intolerances of Scientific Explanation: Introduction

Scientific explanation is often imagined as a progressive smoothing of difficulty. Better data, better models, better theories — and the rough edges are expected to disappear. Disagreement, affect, and resistance are treated as temporary artefacts of incomplete knowledge or social interference.

This series begins from a different observation: some forms of resistance do not disappear with explanatory success — they intensify.

---

Explanation as Stabilisation

To explain is to stabilise.

Every scientific explanation performs a necessary act of construal:

• it selects a unit,

• fixes a level,

• foregrounds certain relations,

• suppresses others.

Without this stabilisation, explanation cannot proceed. There would be no variables, no laws, no mechanisms — only an undifferentiated field. Explanation depends on cuts.

But these cuts are never exhaustive.

---

When Success Generates Resistance

In many scientific domains, the most intense disagreement does not occur at the margins of failure, but at the centre of success:

• Quantum theory predicts with unmatched precision — yet provokes foundational unrest.

• Evolutionary biology explains diversity and adaptation — yet generates persistent disputes over units, levels, and determinism.

• Neuroscience maps mechanisms — yet confronts irreducible phenomenality.

• Economics models rational agents — yet encounters systematic deviation.

• Artificial intelligence optimises behaviour — yet unsettles concepts of agency, meaning, and responsibility.

In each case, the better the explanation works, the sharper the resistance becomes.

This is not accidental.

---

Intolerance as Structural Phenomenon

This series treats intolerance not as error, ignorance, or bad faith, but as a structural signal.

Intolerance appears when:

• an explanatory cut is treated as final,

• a stabilised unit is mistaken for an ontological primitive,

• a perspective is naturalised as reality itself.

What is resisted is not explanation, but closure — the foreclosure of relational possibilities that the cut cannot accommodate.

Anger, polemic, and conceptual revolt mark the point where the field exceeds the form.

---

Relational Diagnosis

Across disciplines, the same pattern recurs:

1. A field of constrained possibility.

2. A necessary explanatory cut.

3. Formal success.

4. Suppression of relations.

5. Resistance and intolerance.

This series does not seek to adjudicate between competing theories, nor to offer a higher-order synthesis that resolves disagreement. Its task is diagnostic rather than reconciliatory.

The aim is to ask, repeatedly and carefully:

• What has been stabilised here?

• What relations have been suppressed?

• What form of intolerance has emerged as a result?

---

Beyond Error and Ideology

By reading intolerance structurally, long-standing scientific disputes can be seen in a different light:

• Not as battles between truth and falsehood.

• Not as conflicts between progress and obstruction.

• But as pressure points where explanation meets its limits.

The persistence of these conflicts is not a sign that science has failed, but that it has reached regions where relational excess cannot be neatly contained.

---

What This Series Will Do

The posts that follow will move across scientific domains, tracing how different explanatory strategies generate different forms of intolerance:

• intolerance of determinism,

• intolerance of reduction,

• intolerance of unitary explanation,

• intolerance of scale,

• intolerance of perspective,

• intolerance of incompleteness.

Each will be treated not as a pathology, but as an intelligible response to the demands and costs of explanation.

---

The Work Ahead

Scientific explanation does not eliminate the field of possibility; it cuts into it. The discomfort that follows is not a problem to be solved, but a phenomenon to be understood.

This series takes that discomfort seriously — not in order to dissolve it, but to read it.

What follows is not a critique of science, but an exploration of the pressures that make science possible at all.

The Same Cut, Repeated

The series of conversations that have unfolded here — first with the architects of quantum theory, then with its interpretations, and more recently with evolutionary biology — may appear to range widely across domains. Physics, biology, history, probability, fitness: the surface diversity is obvious.

What is less obvious, but more important, is that the same structural problem has been appearing again and again.

This work has not been about particles, or genes, or organisms. It has been about explanation under constraint — about what happens when a field of possibility must be cut in order to become intelligible.

---

The Necessity of the Cut

Every scientific explanation begins by stabilising something:

• a unit,

• a variable,

• a law,

• a level,

• a mechanism.

Without such stabilisation, there is no explanation — only an undifferentiated field.

The cut is not an error. It is a necessity. It allows prediction, calculation, coordination, and communication. Quantum theory and evolutionary biology are not exceptional in this regard; they are exemplary.

But the cut is never neutral.

---

Quantum Theory: The Cut at the Limits of Description

In quantum theory, the cut appears at the point where description itself falters:

• the wavefunction stabilises possibility,

• measurement actualises an outcome,

• probability mediates between theory and event.

The interpretive struggles that follow — over collapse, realism, locality, determinism, or multiplicity — do not arise because the theory fails. They arise because the theory succeeds while suppressing relations it cannot accommodate.

What cannot be said is mistaken for what cannot be real. The limits of description are reified as properties of nature.

The resulting discomfort is structural.

---

Evolutionary Biology: The Cut at the Limits of History

In evolutionary biology, the cut appears elsewhere:

• the gene,

• the organism,

• fitness,

• selection,

• lineage.

These stabilisations make evolution describable. They allow patterns to be tracked and mechanisms to be inferred.

But again, the success of explanation generates resistance. Variation, contingency, multi-level causation, and historical singularity press against unitary cuts. What is foregrounded clarifies; what is suppressed returns as critique.

Determinism is resisted. Reduction is resisted. Closure is resisted.

Not because the science is wrong — but because the field is richer than the cut.

---

One Structure, Not Two Analogies

It would be a mistake to treat these cases as merely analogous.

The disputes in quantum foundations and evolutionary theory share the same underlying structure:

• A continuous field of constrained possibility.

• A necessary explanatory cut.

• Formal success.

• Relational suppression.

• Interpretive resistance.

Particles and organisms are not the point of unity. The structure of explanation is.

---

Intolerance as Diagnostic

The intensity of scientific disagreement in these domains is often read as personal, political, or ideological. From a relational perspective, it is better understood as diagnostic.

Intolerance appears precisely where:

• an explanatory cut is pushed too far,

• a unit is treated as ontologically final,

• a perspective is mistaken for a view from nowhere.

Resistance marks the return of suppressed relations.

Einstein’s refusal of dice, Gould’s defence of contingency, Lewontin’s insistence on context, and Bohr’s careful restriction to phenomena all name the same pressure from different directions.

---

The Field of Constrained Possibility

What these debates have been circling is not a missing mechanism or a better model. It is the field within which models become possible at all.

This field is:

• structured, but not fully formalisable;

• constrained, but not deterministic;

• intelligible only through cuts that never exhaust it.

Explanation does not reveal this field directly. It presses against it.

---

Beyond Physics and Biology

If this structure appears in quantum theory and evolutionary biology, it is not because these sciences are uniquely troubled. It is because they operate at points where relational excess cannot be easily hidden.

There is no reason to expect the pattern to stop here.

Wherever explanation requires stabilisation — in neuroscience, economics, climate science, artificial intelligence, or elsewhere — the same cut will be made, and the same resistance will appear.

The task ahead is not to resolve these tensions, but to trace them: to follow the cut as it is repeated across domains, and to read intolerance not as failure, but as signal.

That is the work that now opens.

The Intolerances of Evolutionary Explanation: 4 Relational Field of Evolutionary Debate — Intolerance in Practice

The heated debates between Dawkins, Gould, Rose, and Lewontin are often framed as disagreements over methods, empirical findings, or interpretive preference. Viewed relationally, they are far more revealing: they expose the structural pressures and intolerances inherent in evolutionary explanation.

---

Four Construals, Four Cuts

Each participant enacted a distinct relational cut through the field of evolution:

1. Dawkins — Gene as Unit

   • Privileges a single level of selection.

   • Formalises fitness as a directional, if probabilistic, outcome.

   • Generates the perception of inevitability, and hence provokes resistance.

2. Gould — Variation as Resistance

   • Elevates contingency, heterogeneity, and historical unpredictability.

   • Resists determinism implicit in unitary gene-centred explanation.

   • Protects the relational field against collapse into inevitability.

3. Steven Rose — Multi-Level Relationality

   • Emphasises interactions across organism, population, and environment.

   • Resists reductionist simplification.

   • Ensures causation is distributed and contextual.

4. Lewontin — Structural and Ecological Context

   • Highlights organism–environment interplay and the emergent nature of adaptation.

   • Exposes the insufficiency of unitary explanatory levels.

   • Maintains relational complexity in the face of formal reduction.

Each cut is internally coherent, but each suppresses aspects of the relational field that the others foreground. The intensity of disagreement signals the structural intolerances at play, rather than mere personalities or empirical mistakes.

---

The Intolerances Revealed

Across these debates, several forms of intolerance manifest clearly:

1. Intolerance of unitary cuts: Gene-centred or single-level explanations are resisted when they marginalise other relational levels.

2. Intolerance of determinism: Contingency, variation, and historical unpredictability are defended against formal inevitability.

3. Intolerance of reduction: Distributed, multi-level causation cannot be compressed into a single explanatory scale without resistance.

4. Intolerance of suppression of relational field: Each formalisation or abstraction provokes pushback when it occludes interactions and possibilities that cannot be captured at that level.

These intolerances are not failures; they are the field of evolutionary explanation in action. They reveal how scientific reasoning, affect, and epistemic commitment intersect when relational possibilities are constrained.

---

Relational Reading of the Debate

Viewed relationally:

• Dawkins’ formalism clarifies and constrains.

• Gould’s contingency liberates and pluralises.

• Rose and Lewontin distribute causation across levels, preserving relational richness.

The confrontation is a laboratory of relational cuts, showing how explanatory precision, methodological tractability, and conceptual comfort are balanced against the openness, complexity, and contingency of evolution.

---

Lessons for Evolutionary Thought

1. Explanatory cuts are unavoidable: Science must always foreground some relations and suppress others.

2. Resistance is intelligible: Opposition signals which relational dimensions are being occluded.

3. Plurality is disciplined: Multiple cuts can coexist, revealing different aspects of the same relational field.

4. Understanding emerges relationally: The field, not any single cut, constitutes evolutionary intelligibility.

---

Closing the Mini-Series

Dawkins, Gould, Rose, and Lewontin together illuminate how intolerance operates in evolutionary science — not as personal quarrel, but as structural pressure.

The intensity of these debates teaches a broader lesson: explanation is always perspectival, provisional, and relational. To read evolution fully is to attend to the cuts, to the constraints, and to the forms of resistance they provoke — to see the field, not just the units.

The Intolerances of Evolutionary Explanation: 3 Rose and Lewontin — The Intolerance of Reduction: Multi-Level Relationality in Defence

While Gould resisted determinism by foregrounding variation, Steven Rose and Richard Lewontin — among others — resisted reductionism by emphasising the relational distribution of causation across multiple levels.

Their work reminds us that evolution is never the story of a single unit, trait, or level. It is a network of constraints and actualisations, operating across genes, organisms, populations, and environments simultaneously.

---

The Reductionist Temptation

Reductionism in evolutionary biology manifests as:

• Gene-centrism: privileging the gene as the exclusive bearer of selection.

• Trait-centrism: treating phenotypes as fully predictable from underlying genes.

• Adaptationist narratives: smoothing over complexity by assuming linear causal pathways.

These reductions simplify explanation, improve tractability, and promise clarity — but they suppress relational multiplicity.

Rose and Lewontin observed that this simplification cannot account for what actually occurs in living systems.

---

Multi-Level Causation

Lewontin’s insistence on organism-environment interaction and Rose’s focus on experimental life-history evolution reveal that:

• Fitness cannot be assigned solely to genes or organisms; it emerges relationally.

• Selection acts across interacting levels: gene, cell, organism, population, and ecological context.

• Constraints and opportunities are distributed; outcomes cannot be predicted from any single level alone.

Reductionist explanations obscure these relational dynamics. They attempt to stabilise the field by privileging one level of analysis — a move that relational ontology identifies as an intolerance of relational complexity.

---

The Intolerance Revealed

Rose and Lewontin’s critiques highlight a structural pattern familiar from previous posts:

1. Intolerance of reduction: a refusal to accept that complex causation cannot be compressed into a single explanatory scale.

2. Intolerance of unitary explanation: the field is plural; multiple interacting units participate in actualisation.

3. Intolerance of fixed construals: meaning and causality are distributed and context-dependent; attempts to fix them provoke opposition.

Their arguments are not rhetorical flourish. They are methodological and ontological interventions, defending relational openness against formal compression.

---

Relational Perspective

Viewed relationally, the contributions of Rose and Lewontin are acts of structural preservation:

• They preserve multi-level relationality, ensuring that no single level dominates explanation.

• They preserve ecological and developmental context, resisting the abstraction of traits and units from the field in which they are actualised.

• They preserve contingency, allowing outcomes to remain contingent on distributed constraints rather than predetermined by unitary mechanisms.

In short, they enact resistance as methodology — an intolerance of oversimplification.

---

Consequences for Evolutionary Explanation

By highlighting distributed causation, Rose and Lewontin expose the limitations of formal reduction:

• Fitness is relational, not intrinsic.

• Novelty emerges from interaction, not from a single unit.

• Lineages and patterns cannot be fully stabilised at any one level.

Their work demonstrates that relational cuts are inevitable, but must be made consciously, not imposed by reductionist formalism.

---

Reading Their Critique Relationally

The debates over gene-centrism, reductionism, and adaptationist overreach can thus be interpreted as clashes of relational construal:

• Dawkins’ cut foregrounds one level (gene) and one kind of causation (replication-based fitness).

• Gould’s cut foregrounds variation and contingency.

• Rose and Lewontin foreground distributed, multi-level causation.

Each cut is intelligible within its own frame — and each provokes resistance when it suppresses aspects of the relational field.

---

Looking Ahead

With Gould defending contingency and Rose/Lewontin defending distributed causation, the relational pressures in evolutionary explanation become starkly visible:

• Units are provisional.

• Fitness is relational.

• Novelty cannot be fully predicted.

• Persistence emerges through interaction, not essence.

The final mini-post in this series can draw these threads together as “Relational Field of Evolutionary Debate: Intolerance in Practice”, synthesising these confrontations and highlighting what they reveal about the structure of explanation itself.

The Intolerances of Evolutionary Explanation: 2 Gould and the Intolerance of Determinism — Variation as Resistance

Stephen Jay Gould’s evolutionary vision pivots around one insistence: evolution is not predetermined.

Where Dawkins’ gene-centric view foregrounds directional outcomes through unitary selection, Gould foregrounds variation, contingency, and the open-endedness of history. This is not mere empirical preference. It is a defence against deterministic construal.

---

Variation First

For Gould, variation is not raw material to be sorted by selection.

• Variation is primary, pervasive, and relational.

• Patterns of difference are not subordinate to fitness, units, or optimisation.

• Contingency is not an inconvenience; it is constitutive.

In emphasising variation, Gould refuses to allow evolution to be read as inevitable, predictable, or fully explainable through mechanistic reduction. Variation becomes a resistance to deterministic cuts.

---

Determinism as Target

Gould’s opposition to Dawkins is not simply a matter of genes versus organisms. It is a matter of ontological and explanatory determinism:

• Dawkins’ formalism implies inevitability: given the gene, the trajectory of adaptation follows.

• Gould insists that history matters: the order, timing, and context of variation can redirect evolutionary paths in ways that no single unit can anticipate.

• Contingency ensures that evolution is non-linear, plural, and perspectival.

Gould’s critique highlights what relational ontology foregrounds: actualisation is perspectival, not inevitable.

---

Variation as Relational Cut

Gould treats variation itself as a cut in the field of evolution:

• It is relational, dependent on environment, development, and interaction.

• It cannot be reduced to gene-level differences alone.

• It foregrounds multiplicity, revealing alternative pathways that a deterministic model would obscure.

Variation is simultaneously a phenomenon and a lens: it both exists in the field and structures the way the field can be read.

---

The Pressure of Intolerance

Gould’s resistance exposes a familiar pattern of intolerance:

1. Intolerance of determinism: the imposition of inevitability is rejected.

2. Intolerance of reductionism: single-unit explanations are insufficient for relational multiplicity.

3. Intolerance of reification: traits, lineages, and adaptations cannot be fully treated as stable entities.

These intolerances are not failures of reasoning. They are structural pressures generated when relational possibilities confront formal simplification.

---

Emergence, Contingency, and Open-Endedness

Gould’s emphasis on contingency allows emergence to appear without being tamed:

• Traits arise not from inevitability, but from the interaction of multiple relational constraints.

• Patterns persist not because they are optimal, but because they survive in context.

• History matters: what occurs depends on what came before, but also on how it came.

This relational approach foregrounds possibility over necessity, resisting the temptation to reduce evolution to deterministic computation.

---

Anger as Epistemic Signal

The spirited opposition to Dawkins is instructive. It reveals that:

• Resistance is often driven by epistemic and ontological stakes, not personality.

• Intolerance is a signal of what is at stake in construal: the preservation of relational multiplicity, contingency, and non-deterministic becoming.

• Scientific argument and affect are entangled when the field of possibility is threatened by overly formal cuts.

---

Relational Takeaway

Gould teaches that variation is not secondary, not merely raw material, not a statistical backdrop.

It is a field of resistance — a way to preserve relational openness against the sedimenting pressures of determinism and reduction.

To read Gould relationally is to see resistance as method, and contingency as structure.

---

Looking Ahead

The next post in this mini-series can explore Rose and Lewontin — the Intolerance of Reduction.

Here, the focus will shift from the philosophical defence of contingency to multi-level, distributed, and ecological relationality — further tracing how evolutionary thought generates intolerances when confronted with relational pressures.

The Intolerances of Evolutionary Explanation: 1 Dawkins and the Gene as Unit — Intolerance in Action

When Richard Dawkins foregrounded the gene as the central unit of selection, he did more than propose a convenient analytical abstraction. He reordered the explanatory field of evolutionary theory.

Genes became the locus of persistence, the bearers of “fitness,” the axes along which adaptation was to be understood. And with this formal move came an implicit determinism: given variation, given differential replication, outcomes could be traced — at least in principle — along predictable pathways.

---

The Gene as Cut

From a relational perspective, Dawkins’ gene is a cut through the field of evolution:

• It foregrounds certain relations (inheritance, replication, differential success).

• It suppresses others (developmental contingency, ecological interaction, multi-level causality).

This cut is formal, elegant, and productive. But it is not neutral. It shapes what can be seen as explanation, privileging mechanistic causality at one scale over relational multiplicity across scales.

---

The Roots of Controversy

The opposition of Stephen Jay Gould, Rose, Lewontin, and others cannot be reduced to mere empirical disagreement. Their unease is epistemic and ontological:

• Dawkins’ formalism appears deterministic, even if probabilistic. Outcomes are framed as necessary given the success of particular genes.

• Gould emphasises variation, contingency, and developmental plasticity, preserving relational multiplicity and resisting inevitability.

• Rose and Lewontin highlight environmental, organismic, and population-level interactions, showing that causation is distributed, contextual, and perspectival.

In short, the conflict is a clash of construals: one seeks explanation through unitary, directional cuts; the other defends the relational field itself.

---

Intolerance in Action

What emerges is a vivid illustration of intolerance at the level of perspective and unit:

1. Intolerance of unit: Gene-centrism marginalises organism, population, and ecological levels, provoking defensive resistance.

2. Intolerance of determinism: Gene-level inevitability threatens relational multiplicity and the open-endedness of variation.

3. Intolerance of reduction: Compressing evolutionary causation into a single formalism provokes pushback from those attuned to multi-level complexity.

The heat of debate is not simply personal or rhetorical. It is a visible manifestation of the pressures inherent in evolutionary explanation — the intolerances that the previous series traced abstractly now take concrete form.

---

Relational Perspective

Viewed relationally, the Dawkins-Gould debates are not zero-sum disputes about correctness. They are contests of construal:

• Dawkins’ construal prioritises clarity, formal tractability, and selective focus.

• Gould’s construal prioritises relational multiplicity, historical contingency, and emergent unpredictability.

Neither is “wrong.” Each enacts a cut through the field of constrained possibility, highlighting some aspects while suppressing others. The intensity of disagreement reveals how intolerances operate when construals collide in practice.

---

What This Illuminates

This episode shows:

• Intolerance can appear as scientific rigour.

• Deterministic formalism may provoke resistance even in empirical science.

• The stakes in methodological choices are ontological as well as explanatory.

• Relational cuts always produce shadows — aspects of the field that are displaced, overlooked, or resisted.

The Dawkins-Gould-Rose-Lewontin confrontation thus becomes a laboratory of intolerance, a case study in how perspective, unit, and determinism generate both insight and opposition.

Looking Ahead

Subsequent posts in this mini-series can trace:

1. The finer contours of Gould’s anti-determinism and its insistence on relational variation.

2. Rose and Lewontin’s critique as a defence of multi-level and distributed explanation.

3. The ways these conflicts illuminate broader structural intolerances in evolutionary thought.

This mini-series will not adjudicate who was “right.” It will show the pressures, constraints, and relational dynamics that make evolutionary theory intellectually and emotionally charged.

Evolution Without Essence: 6 Evolution as a Field of Constrained Possibility

The evolutionary series does not offer final answers. It does not declare a privileged unit, locate the “true” fitness, or define the essence of novelty. It refuses closure.

And yet, it offers something equally rigorous: a vision of evolution as a field of constrained possibility, where patterns persist, actualise, and transform — not as objects with intrinsic identity, but as emergent outcomes of relational cuts.

Variation, Fitness, Units, Novelty, and Lineage

Across the series, five pressures converge:

1. Variation Without Ground — the restless heterogeneity that precedes selection, unanchored by essence.

2. The Intolerance of Fitness — the refusal to accept that differential persistence is relational, contextual, and emergent.

3. The Intolerance of the Unit — the demand for a bearer of selection, resisted by the distributed nature of evolutionary processes.

4. The Intolerance of Novelty — the compulsion to reframe emergence as recombination, rather than allowing genuine difference.

5. The Intolerance of Lineage — the insistence on persistent entities across time, resisted by non-identity and relational persistence.

Each intolerance is an attempt to stabilise explanation, to preserve coherence, and to protect intelligibility. Each is also a refusal: of relationality, of incompleteness, of becoming.

What Evolution Refuses

Evolutionary thought has long struggled with the implications of what it describes:

• No entity persists fully; identity is partial and context-dependent.

• Novelty is not reducible; emergence cannot be entirely explained retrospectively.

• Selection is not localised; it is distributed across interacting constraints.

• Fitness is relational; it is not a property to be possessed, only a pattern to be enacted.

Science often responds to these pressures with compensatory measures: adaptationist narratives, gene-centrism, optimisation metaphors, hierarchical units. These strategies make evolution palatable — but they obscure its relational character.

Evolution as Relational Discipline

From a relational perspective, evolution is not about discovering fixed truths.

It is about observing how possibilities are constrained, actualised, and patterned.

• Variation is the material of possibility.

• Selection is the articulation of constraint.

• Units are provisional lenses through which patterns are seen.

• Novelty is the emergence of previously unactualised possibilities.

• Lineages are patterns of persistence enacted through relational cuts.

Explanation is not the enumeration of essences. It is the disciplined tracing of relations.

A Field, Not a Map

The evolutionary landscape is not a terrain to be fully mapped.

It is a field in which:

• multiple patterns coexist, intersect, and diverge

• relational constraints shape outcomes without determining them

• persistence and change co-occur, without reducing one to the other

• explanation is partial, perspectival, and accountable

The field does not yield a single, privileged description. It allows multiple, overlapping, and mutually incompatible perspectives — all disciplined by relational actualisation.

---

What This Concludes

The evolutionary series does not offer closure.

It does not resolve debates over units, fitness, novelty, or lineage.

It does something more subtle: it shows how the very intelligibility of evolutionary explanation depends on what is repeatedly refused — the relational, the incomplete, the emergent, the distributed, the provisional.

To see evolution fully, one must see the intolerances and let them speak together.

Becoming Without Essence

If quantum theory taught that phenomena are relationally cut and constrained, evolution teaches that life itself is relationally patterned.

Persistence, change, emergence, and selection are not accidents or defects. They are the actualisation of possibilities within a field of constraints.

To read evolution relationally is not to simplify. It is to attend to the discipline of participation: the patterns that hold, the possibilities that unfold, and the cuts through which explanation is enacted.
