Why APS Is Not Holism — An APS Clarification

APS strongly rejects reductionist approaches that attempt to explain living systems entirely in terms of isolated components, molecular mechanisms, or local causal interactions considered independently of the organised systems within which they operate. Because of this, readers sometimes conclude that APS must therefore be a form of holism.

This interpretation is understandable but ultimately misleading.

APS agrees that organisms cannot be adequately understood as mere aggregates of separable parts. Living systems are organisationally integrated, historically situated, and dynamically maintained across multiple scales. Biological explanation therefore cannot proceed through decomposition alone.

However, APS does not respond to these limitations by replacing reductionism with an unrestricted appeal to “the whole.” It does not invoke mysterious emergent powers, deny the legitimacy of mechanistic analysis, or treat wholes as explanatorily sufficient in themselves.

Instead, APS proposes that biological explanation depends on understanding how components participate in viability-oriented, constraint-closed processes of organised persistence.

The framework is therefore organisational rather than merely holistic.

Why APS Is Often Mistaken for Holism

APS emphasises several themes historically associated with holistic biology.

These include:

• the organisational unity of organisms,
• the interdependence of biological components,
• the importance of relational structure,
• multi-scale integration,
• and the inadequacy of purely atomistic explanation.

APS also argues that biological properties such as function, normativity, adaptation, and agency cannot be adequately understood through isolated local mechanisms alone. Biological significance depends on how processes contribute to the continued persistence of the organised system.

Because APS repeatedly stresses organisation, integration, and system-level persistence, it can initially resemble broader holistic traditions in biology and philosophy.

Yet this resemblance must be interpreted carefully.

APS does not argue that wholes possess irreducible mystical powers, nor that scientific analysis should be abandoned in favour of global description. Instead, it argues that biological explanation requires understanding the organisational relations through which systems maintain themselves across time.

The explanatory target is not “wholeness” itself, but organised persistence.

What Holism Traditionally Means

Holism has appeared in many different forms throughout the history of biology and philosophy.

Some forms emerged as reactions against mechanistic reductionism, arguing that living systems possess properties that cannot be derived from isolated parts alone. Early twentieth-century organicist and holistic traditions frequently emphasised organisation, integration, developmental coordination, and organism-level unity.

Jan Smuts’ Holism and Evolution (1926) gave one of the most famous formulations of this perspective, presenting wholes as fundamental features of nature rather than merely collections of parts. Organismic biologists and systems theorists later developed related approaches emphasising hierarchical organisation, systemic interaction, and the limitations of reductionist explanation.

General systems theory, associated especially with Ludwig von Bertalanffy, argued that biological systems display organisational principles not adequately captured through linear mechanistic decomposition alone. Later traditions in systems biology, dialectical biology, autonomy theory, and process philosophy likewise stressed the importance of relations, organisation, and dynamic integration.

These traditions identified genuine limitations in strongly reductionist accounts of life.

However, “holism” has often remained conceptually ambiguous.

In some contexts it refers simply to organisational integration. In others it implies explanatory irreducibility, anti-mechanism, or even metaphysical claims about wholes possessing autonomous causal powers independent of their material organisation.

APS does not adopt these stronger interpretations.

What APS Accepts from Holistic Traditions

APS agrees with several major insights associated with holistic and organismic traditions.

First, organisms are not merely collections of independently existing parts. Biological components acquire their significance through their participation in organised systems of activity.

Second, relations matter biologically. The role of a structure or process cannot be understood solely through its isolated physical properties. Biological function depends on how components contribute to the maintenance and persistence of the organised system.

Third, explanation in biology must often proceed across multiple scales simultaneously. Cellular, physiological, behavioural, developmental, ecological, and evolutionary processes interact in ways that cannot be adequately represented through purely local accounts.

Fourth, organisms actively maintain themselves. Living systems are not passive objects but dynamically organised processes continuously regenerating the conditions of their own persistence.

APS therefore shares with many holistic traditions a rejection of strict atomism and an emphasis on organisation, integration, and systemic dependence.

Why APS Is Not Simply Holism

Despite these overlaps, APS differs fundamentally from many forms of holism.

APS does not reject analysis or decomposition. Mechanistic explanation remains indispensable to biology. Molecular pathways, physiological mechanisms, genetic regulation, ecological interaction, and developmental processes all contribute to biological explanation.

The problem is not analysis itself.

The problem arises when isolated mechanisms are treated as explanatorily sufficient independently of the organised systems within which they function.

APS therefore rejects reductionism without rejecting analytic inquiry.

Nor does APS claim that wholes possess mysterious properties existing independently of organisational structure. Biological organisation is not treated as a metaphysical essence hovering above material processes. Instead, organisation refers to empirically tractable patterns of constraint, regulation, coordination, and persistence.

APS also avoids treating “the whole” as explanatorily primary in a simple top-down sense. Organised systems exist only through the continuous activities of their components, while components acquire their biological significance through participation in the organised system. Explanation therefore proceeds through reciprocal organisational relations rather than through the unilateral priority of either parts or wholes.

APS is therefore neither atomistic nor anti-analytic.

It is organisational.

Organisational Explanation Versus Holistic Description

Many holistic frameworks successfully emphasise integration while remaining comparatively vague about the mechanisms through which organisation is maintained.

APS attempts to move beyond holistic description toward organisational explanation.

The central question is not merely whether organisms behave as unified wholes. The question is how organised systems continuously regenerate the conditions of their own persistence across time.

This shifts explanatory attention toward:

• viability maintenance,
• constraint organisation,
• functional integration,
• adaptive regulation,
• process continuity,
• and scale-dependent coordination.

APS therefore treats organisation as an explanatory structure rather than as a descriptive label.

Biological properties become intelligible through their roles in the ongoing maintenance of viability-oriented organisation.

Function concerns contributions to persistence.

Normativity concerns the conditions under which organisation succeeds or fails.

Adaptation concerns the modulation of organisation across changing conditions.

Evolution concerns the historical transformation of organised persistence across lineages.

In this sense APS attempts to provide an explanatory grammar for biology rather than a general appeal to systemic wholeness.

Organisation Rather Than Wholeness

APS does not begin with the abstract idea of “the whole.”

It begins with organised biological activity.

Living systems persist only because they continuously regulate, repair, reorganise, and reproduce the conditions enabling their own continued existence. Organisms therefore cannot be adequately understood either as static structures or as mere collections of mechanisms.

They are temporally extended processes of organised persistence.

This organisational perspective explains why biological entities:

• display functional normativity,
• maintain internal coherence,
• regulate perturbations,
• adapt across changing environments,
• and preserve continuity across time.

The explanatory focus is therefore not wholeness as such, but the organisation through which viability is sustained.

APS accordingly differs both from reductive atomism and from forms of holism that appeal to undifferentiated systemic unity without specifying the organisational relations involved.

APS as an Organisational Framework

APS proposes that biological explanation must integrate:

• agency,
• process,
• scale,
• persistence,
• and organisational constraint.

These dimensions together provide a framework for understanding how living systems maintain themselves across time while remaining open, dynamic, and historically transformable.

The framework therefore rejects the false opposition between reductionism and holism.

Reductionism becomes inadequate when organisation disappears from explanation.

Holism becomes inadequate when organisation is replaced by vague appeals to integrated wholes.

APS instead proposes an organisational approach in which:

• mechanisms matter,
• components matter,
• relations matter,
• scales matter,
• and persistence matters.

Biology becomes intelligible not through isolated parts alone, nor through abstract wholes alone, but through the organised processes by which living systems sustain themselves across time.
