Cognition — Where Does It Belong in Biology?

Abstract

This article repositions cognition within biology as a specific organisational development of viability-oriented systems rather than a general feature of life or a specialised property of nervous systems. It shows how cognition arises when evaluative activity becomes temporally extended and integrated, enabling present regulation to be structured in relation to conditions beyond the immediate present.

What This Article Does

This article clarifies where cognition belongs within biology. Rather than treating cognition as a specialised mental domain associated with brains, behaviour, or information processing alone, APS situates cognition within the organisation of viability-oriented living systems.

For an account of how biological explanation is structured, see The Explanatory Geometry of Biology. For how such explanations are evaluated, see APS Diagnostics.

The question addressed here is:

If living systems are viability-oriented organisations, what role does cognition play in sustaining that organisation?

The Conventional Placement of Cognition

Cognition is often treated as a late and specialised development in evolution. It is typically associated with:

nervous systems
information processing
representation and internal models
behaviour in complex organisms

Within this framing, cognition appears as an add-on to biological organisation—something that only certain organisms possess.

This creates a separation between:

life (basic biological organisation)
and cognition (advanced mental capacity)

APS rejects this separation.

Nor does APS identify cognition with computation, information processing, or behavioural complexity considered independently of viability-oriented organisation.

This difficulty reflects a more general issue in how cognitive concepts are extended across biological systems.

APS Box — Biological and Psychological Interpretation

Cognition is often interpreted through concepts derived from human psychology—perception, memory, reasoning, and decision-making. When these concepts are applied across biological systems, two contrasting interpretive tendencies can arise.

One approach understands human cognition as a specialised form of more general biological organisation. On this view, cognitive capacities are grounded in viability-oriented activity through which organisms differentiate and respond to conditions relevant to their persistence. Human cognition is then a highly integrated and extended form of this broader biological organisation.

A second approach interprets other organisms through human psychological categories, attributing features such as perception, memory, or decision-making in ways that may depend on specifically human forms of organisation. While this can be heuristically useful, it risks projecting categories beyond the conditions under which they are well-defined.

APS clarifies this distinction by grounding cognition in biological organisation rather than in human psychological categories. What varies across organisms is not whether cognition is present, but how viability-oriented activity is organised, integrated, and extended across time.

This distinction reflects a more general feature of explanatory grammar: concepts can be extended across domains either by abstracting their organisational basis or by projecting domain-specific categories. Only the former preserves explanatory coherence.

Cognition as a Property of Living Organisation

APS begins from a different starting point: living systems are viability-oriented, constraint-closed organisations that must continuously sustain the conditions of their own persistence.

This shift requires a clarification of what is meant by cognition in APS:

APS Box — What APS Means by Cognition

In APS, cognition does not refer to thought, consciousness, or representation. It refers to a mode of biological organisation.

Cognition is the structured, temporally extended organisation of evaluative activity through which living systems regulate viability-relevant differences beyond the immediate present.

Living systems do not passively receive or encode information. Their organisation determines what counts as a relevant difference and how that difference is acted upon. Cognition is the way this selective differentiation is structured and coordinated within systems whose activity is oriented toward their own persistence.

All living systems exhibit biological agency and evaluative responsiveness, but cognition arises only where this activity becomes sufficiently structured, integrated, and temporally extended. Cognition develops where evaluative semiosis becomes coordinated across time in ways that regulate activity beyond immediate conditions.

In more elaborated systems, cognition may involve:

integration across multiple viability-relevant conditions
context-sensitive modulation of activity
temporal extension (counterfactual depth), where present activity reflects past or possible conditions
cross-scale coordination linking local processes with system-wide organisation

These are not defining requirements, but ways in which the organisation of cognition can become more complex.

Cognition, in this sense, is not a separate layer added to life. It is a developed mode of evaluative biological organisation emerging from viability-oriented activity when that activity becomes sufficiently structured, integrated, and temporally extended. It does not require subjective awareness or reflective thought.

With this clarification in place, cognition can be located precisely within biological organisation. It is not a general feature of all living systems, but a specific way in which viability-oriented activity becomes organised.

This requires more than passive maintenance. Systems must:

differentiate between conditions that support or threaten viability
regulate their interactions with the environment
reorganise in response to changing conditions

This differentiation is structured through semiosis: the way in which differences come to matter for the system in relation to viability.

These activities are intrinsically evaluative: they involve the differential modulation of activity in relation to conditions that support or undermine viability. They involve determining what matters for continued existence and acting accordingly.

From this perspective, cognition is not an additional feature layered onto life, but a specific organisational development within it.

Cognition arises only when viability-oriented evaluation becomes sufficiently integrated and temporally extended such that present activity is structured in relation to conditions beyond the immediate present.

Cognition can therefore be understood as the temporally extended integration of evaluative activity across the system, coordinating multiple agential processes in relation to viability across non-immediate conditions.

This integration does not require any particular anatomical structure or representational architecture. Different organisms may realise similar cognitive capacities through very different material organisations while participating in related functional lineages. What persists across such lineages is not structural identity but the continuity of viability-oriented organisational roles.

It therefore does not emerge wherever living systems sustain themselves, but only where evaluative activity exhibits counterfactual depth and system-wide coordination.

Counterfactual depth refers to the extent to which evaluative activity is organised in relation to conditions not immediately present but still relevant to viability.

From Viability to Evaluation

The transition from organisation to cognition can be made explicit.

Viability defines the conditions required for persistence
Normativity establishes what matters relative to those conditions
Evaluation is the differential modulation of activity in relation to those conditions
Semiosis structures differences as mattering within that modulation
Cognition arises when this evaluative activity becomes temporally extended and integrated across the system

This sequence does not introduce new entities. It makes explicit a structure already present in living organisation.

Cognition therefore does not introduce a separate explanatory domain beyond life, but a further organisational development within viability-oriented evaluation itself.

Evaluation is the enactment of normativity in real time: it is how systems modulate their activity in relation to what sustains or undermines their persistence.

Cognition is a further development of this process. It arises when evaluative activity is organised such that present regulation is structured in relation to conditions that are not currently realised but remain relevant to viability.

In this sense, cognition is not identical with evaluation, but what evaluation becomes when it is extended across time and coordinated at the level of the system as a whole.

This clarification of cognition is part of a broader pattern in biological explanation, in which widely used concepts capture real phenomena but require grounding in explicit organisational terms.

APS Box — Why APS Replaces Placeholder Concepts

Biological explanation often relies on concepts such as emergence, information, design, and cognition to describe complex organisation and system-wide behaviour. These terms capture real features of living systems, but they are frequently used as explanatory placeholders: they mark phenomena without specifying the organisational conditions that produce and sustain them.

APS clarifies these concepts by grounding them in viability-oriented, constraint-closed organisation. Rather than treating them as explanatory primitives, it shows how they arise from the structured organisation of activity in living systems.

Emergence refers to the reorganisation of constraint-closed systems across scale and time
Information reflects differences that matter for viability through evaluation and semiosis
Cognition arises when evaluative activity becomes sufficiently integrated and temporally extended
Design is the structured organisation of activity through which systems sustain their own persistence

These are not separate explanatory domains, but different expressions of the same underlying organisation. APS replaces placeholder concepts with an explicit account of how biological systems are organised, maintained, and transformed.

Key Point
APS does not eliminate concepts such as emergence, information, design, and cognition, but re-specifies them within a unified framework of viability-oriented, constraint-closed organisation.

Cognition Without Representation

In many accounts, cognition is defined in terms of representation: systems are said to model or encode the world internally. APS does not require this assumption.

A system can evaluate its environment without representing it in a symbolic or model-based sense. What matters is whether differences in the environment:

affect the system’s viability
are detected and acted upon
are integrated into ongoing regulation

Cognition in this sense is grounded in viability-oriented function and organisation rather than in internal symbolic representations or computational models alone.

APS therefore distinguishes biological cognition from adaptive information processing alone. Artificial systems may simulate responsiveness, optimisation, or context-sensitive behaviour while remaining externally maintained systems lacking viability-oriented organisational persistence. For a fuller discussion, see Why AI Is Not Biological Agency.

This allows cognition to be understood as a biological phenomenon grounded in life processes, but not identical with them.

Meaning in APS is not representational content, but the organisation of differences that matter for viability within evaluative activity.

Degrees of Cognition

Cognition is not all-or-nothing, but neither is it ubiquitous. It arises only when evaluative activity is organised with counterfactual depth.

Systems differ in:

the range of conditions—present, past, or possible—that are integrated into their evaluative organisation
the flexibility and context sensitivity of their responses
the extent to which activity is coordinated across time and scale

More complex organisms exhibit more elaborate forms of cognition, but these build on the same underlying organisational pattern rather than introducing a fundamentally different kind of process.

This also allows cognition to be compared across structurally diverse organisms. Different systems may belong to related functional lineages despite major differences in anatomy or mechanism, provided they sustain comparable forms of temporally extended evaluative organisation.

Cognition therefore admits of degrees, but only within systems that satisfy the conditions for its presence. It spans a continuum:

from minimally integrated, shallow forms of temporally extended evaluation
to highly integrated, flexible, and multi-scale coordination of activity across time

This graded structure allows cognition to be compared across systems without treating all viability-oriented regulation as cognitive. A distinction is therefore maintained between non-cognitive systems, in which evaluation remains tightly coupled to immediate conditions, and cognitive systems, in which evaluation is organised with respect to non-present conditions.

Cognition and Biological Agency

Cognition and biological agency are closely related but not identical.

Agency refers to the ongoing activity through which a system sustains its own organisation
Evaluation refers to how that activity is differentially modulated in relation to viability
Cognition refers to a further organisational development in which evaluative activity is temporally extended and integrated

Cognition can therefore be understood as a specific mode of agency in which evaluation is organised across time.

Cognition is not the presence of evaluation as such, but what evaluation becomes when it is structured in relation to conditions beyond the immediate present.

This relationship ensures that cognition remains grounded in biological organisation while preserving a clear distinction between life, evaluation, and cognition.

Implications for Biology

Repositioning cognition in this way has several consequences.

First, it situates cognition within biology as a whole, rather than isolating it within neuroscience or psychology.

Second, it provides a principled framework for comparing systems across scales without relying on behavioural or representational criteria. This comparison is grounded in functional lineage rather than structural similarity alone, allowing cognitive continuity to be understood organisationally across diverse forms of life.

Third, it aligns cognition with the same explanatory and diagnostic principles that apply elsewhere in APS.

Cognition is therefore explained through the same organisational grammar governing biological explanation more generally.

it is explained through the relations of agency, process, and scale
it is evaluated through perturbation and viability-relative outcomes

Cognition is therefore not an exception within biology, but a specific organisational development within how living systems sustain themselves.

Where Cognition Belongs

Cognition belongs neither outside biology nor at its upper limits. It belongs:

within the organisation of life itself, as a specific form of evaluative activity in which present regulation is structured in relation to conditions beyond the immediate present.

Understanding cognition in this way allows it to be integrated with the rest of the APS framework without introducing new explanatory categories.

Spatiotemporal organisation also underlies evaluation and cognition (see Spatiotemporal Organisation and Scale). The differential modulation of activity depends on how processes are distributed and coordinated across space and time, determining what can be detected, integrated, and acted upon. In systems that exhibit cognition, this organisation extends across time such that present activity is structured in relation to conditions beyond the immediate present. This temporal extension corresponds to counterfactual depth: the extent to which non-present conditions are integrated into ongoing regulation. In this way, spatiotemporal organisation conditions what matters for the system and how it can respond, grounding the emergence of more complex forms of coordination such as cognition without introducing additional representational structures.
