The Cost Language Made Precise
Evan Thompson’s enactive framework makes your “cost” language precise: cognition is not neutral information processing but life-maintaining sense-making that is inherently metabolic, precarious, and thus costly [1].
Enactive Cognition: Action, Not Representation
Thompson, building on Varela and Rosch, defines the enactive approach by rejecting the idea that cognition is the internal manipulation of representations of an independent world.
Instead, cognition is:
“The enactment or bringing forth of a world of significance through embodied action,” not the mirroring of a pregiven environment. [2]
The Internet Encyclopedia of Philosophy summarizes this core shift: enactivism “rejects the standard view that cognition consists in building up internal representations” and holds that cognitive agents “actively bring forth or enact their own cognitive domains.” [4]
The Nemetic Translation
This is your point that:
“The organism doesn’t process information about its environment; it enacts an environment.“
What counts as a world for the agent is constituted through its ongoing activities and sensitivities, not passively received.
Structural Coupling and Autonomy
A key enactive concept is structural coupling: a living system and its environment mutually specify each other through recurrent interaction without losing their organizational autonomy [4].
Thompson and Di Paolo describe the enactive view as treating the body as an autonomous system that:
“Actively generates and maintains the distinction between itself and its environment,” rather than being simply identified by external convention. [4]
Autonomy = Operational Closure + Precariousness
This autonomy depends on: - Operational closure: the system’s processes are self-organizing - Precariousness: constantly on the edge of breakdown, must continually counteract tendencies toward disintegration
Di Paolo and Thompson explicitly connect this to metabolism:
Autonomy is modeled as a network of metabolic processes far from thermodynamic equilibrium that must incessantly “buy time” against entropy. [1]
This is exactly your “metabolism, not replication”: the organism is not copying information; it is perpetually remaking itself in a materially costly coupling with its surroundings.
Mind in Life: Life-Mind Continuity and Cost
In Mind in Life, Thompson defends the life-mind continuity thesis:
“Mind is literally life-like, and basic cognition is continuous with, and grounded in, the self-organizing, self-maintaining activity of living systems.”
Mind does not appear ex nihilo at the level of brains; rather, the brain “expands the range of mind already present in life.” [3]
Sense-Making as Normative Dimension
The enactive notion of sense-making captures the normative dimension of this coupling:
An autonomous system “produces and sustains its own identity in precarious conditions… and thereby establishes a perspective from which interactions with the world acquire a normative status.” [3]
From this standpoint, a system is cognitive when its behavior is governed by the norm of its own continued existence and flourishing, not by the accurate representation of an external reality.
The Cost of Meaning
Thompson puts it as:
“Meaning is generated within the system for the system itself—that is, it is generated and at the same time consumed by the system.” [3]
Sense-making is metabolic: meaning is produced and consumed in the same act, at a material cost, against entropy, at the edge of breakdown.

Enactive Cognition (E011)
Φ(Enactive_Cognition) = γ(enactment-process) ∘ ρ(coupling-resonance)
∘ β(sense-making) ∘ σ(self-environment) + ε | :cycling
γ (cycling) in primary position: cognition as ongoing process, not representation.
β (exploration) as sense-making: bringing forth world of significance.
Structural Coupling (E012)
Φ(Structural_Coupling) = ρ(recurrent-resonance) ∘ σ(autonomy-distinction)
∘ γ(coupling-process) ∘ δ(precarious-transformation) + ε | :cycling
ρ (resonance) in primary position: mutual specification through interaction.
δ (transformation) as precariousness: constantly on edge of breakdown.
Sense-Making (E013)
Φ(Sense_Making) = γ(identity-sustaining) ∘ ρ(normative-resonance)
∘ σ(perspective-distinction) ∘ β(flourishing-seeking) + ε | :cycling
γ (cycling) as identity-sustaining: producing/consuming meaning in precarious conditions.
ρ (resonance) as normative: world acquires meaning from system perspective.
The Costly Stack
| Level | Concept | Thinker | Cost Dimension |
|---|---|---|---|
| Biology | Sense-Making (E013) | Thompson | Metabolic, precarious, buying time against entropy |
| Ontology | Actual Occasion (A003) | Whitehead | Prehending, metabolizing past |
| Method | Tentacular Thinking (WO007) | Haraway | Staying with trouble, no overview |
| Infrastructure | Tertiary Retention (M010) | Stiegler | External memory, pharmakon |
The Core Insight
Cognition is not neutral information processing.
Cognition is life-maintaining sense-making.
Cognition is inherently metabolic, precarious, and costly.
The organism must incessantly “buy time” against entropy—perpetually remaking itself, generating and consuming meaning, at the edge of breakdown.
The Question
The question is not: “What does the organism know about its environment?”
The question is: “What world is the organism enacting? What does it cost to maintain? And how close to the edge is it willing to go?”
