Why APS Is Not Organicism

APS shares important concerns with historical organicism. Both approaches emphasise that living systems are not merely collections of independent parts, but organised and self-maintaining wholes whose components derive their significance from the organisation of the system as a whole.

For this reason APS may initially appear to belong within the organicist tradition of theoretical biology. APS rejects strongly reductionistic conceptions of life, emphasises organisation and persistence, and treats organisms as dynamically integrated systems rather than passive assemblies of material components.

Yet APS is not simply a contemporary form of organicism.

Historical organicism was an important attempt to defend the distinctive organisation of living systems against both mechanistic reductionism and vitalism. However, many forms of organicism remained conceptually broad, operationally imprecise, and insufficiently diagnostic. APS inherits several of the core insights associated with organicist biology while reconstructing them through explicit organisational, explanatory, and empirical criteria.

The result is not a rejection of organicism, but a reconstruction of its strongest insights within a more operational and biologically tractable framework.

What Was Organicism?

Organicism emerged in the late nineteenth and early twentieth centuries as a response to two dominant approaches to life.

The first was mechanistic reductionism, which attempted to explain organisms entirely in terms of machine-like interactions among isolated parts. The second was vitalism, which proposed that living systems depended upon special non-physical forces or principles irreducible to ordinary physical processes.

Organicism rejected both positions.

Against mechanism, organicists argued that organisms could not be adequately understood as mere aggregates of components. Biological systems exhibited organisation, integration, regulation, development, and persistence in ways that could not be captured through atomistic analysis alone.

Against vitalism, most organicists insisted that organisms remained fully natural systems. The distinctive features of life did not require mysterious vital forces, but instead arose from the organised relations among components within the living system itself.

Although organicism took many forms, several recurring themes characterised the tradition:

• organisms are organised wholes rather than mere collections of parts,
• biological explanation requires attention to system-level organisation,
• parts derive their functions from their roles within the larger system,
• living systems actively maintain themselves across time,
• biological causation is distributed across multiple organisational scales.

These themes strongly influenced later developments in systems biology, cybernetics, autonomy theory, process philosophy, developmental systems theory, and contemporary organisational approaches to biology.

What Organicism Got Right

Many of the central intuitions of organicism remain important.

Organisms are not adequately understood as static objects assembled from independently meaningful parts. Living systems persist only through continuous processes of self-production, regulation, repair, exchange, and reorganisation. Biological organisation therefore matters explanatorily.

APS strongly agrees with this general orientation.

In APS, living systems are understood as viability-oriented, constraint-closed organisations sustained across time. Biological explanation therefore cannot be reduced exclusively to the local behaviour of isolated components detached from the organised systems within which those components function.

A membrane, enzyme, signalling pathway, or behavioural process has biological significance only insofar as it contributes to the persistence and viability of the larger organised system.

APS also agrees with the organicist insight that biological explanation is inherently multiscale. Organisms are neither reducible to molecular events nor explainable solely through global descriptions detached from underlying processes. Biological intelligibility instead depends upon understanding the reciprocal relations among processes occurring across multiple organisational scales.

Similarly, APS shares the organicist emphasis on persistence. Living systems exist only insofar as they continuously regenerate and stabilise the conditions necessary for their continued existence. Organisms are therefore not passive structures but ongoing organisational processes.

In these respects APS clearly belongs within the broader organism-centred and organisational traditions of theoretical biology.

Why Classical Organicism Was Insufficient

Despite these important insights, historical organicism often remained insufficiently precise as an explanatory framework.

Many organicist accounts correctly emphasised the importance of organisation while failing to specify exactly what organisational properties distinguished living systems from non-living systems. Terms such as “integration”, “wholeness”, or “organismic order” were frequently invoked without explicit operational criteria capable of distinguishing biological organisation from other forms of physical organisation.

As a result, organicism sometimes drifted toward explanatory vagueness.

In some cases organicist writing also adopted a strongly anti-mechanistic tone that obscured the legitimate role of mechanistic explanation in biology. APS rejects this opposition. Mechanistic explanations remain indispensable for biology, but mechanisms themselves only become biologically meaningful within the organised systems whose persistence they contribute to maintaining.

Classical organicism also generally lacked explicit diagnostic criteria. It often identified living systems through broad descriptive properties rather than through operationally tractable organisational features capable of empirical investigation.

APS attempts to address these limitations directly.

Rather than appealing to organismic wholeness in a general sense, APS specifies particular organisational features associated with living systems:

• viability-oriented organisation,
• endogenous constraint maintenance,
• scale-integrated regulation,
• organisational persistence,
• perturbation-sensitive self-maintenance,
• constraint closure.

These concepts provide explanatory and diagnostic structure absent from many earlier organicist approaches.

APS as an Organisational Reconstruction

APS can therefore be understood as a reconstruction and operationalisation of several important organicist insights rather than as a simple continuation of historical organicism itself.

APS preserves the central idea that biological systems must be understood organisationally. However, it attempts to specify the relevant organisational principles in a more explicit and empirically tractable way.

In APS:

• organisation is linked explicitly to viability,
• biological agency is treated as organisationally grounded activity,
• functions are defined in relation to persistence and organisational contribution,
• normativity emerges from viability conditions,
• explanatory structure is organised through agency, process, and scale,
• biological identity is understood processually rather than statically.

This produces a framework that is simultaneously organisational, mechanistically compatible, and diagnostically operational.

APS therefore does not reject mechanistic explanation. Instead, it situates mechanisms within a broader account of organised persistence. Mechanisms matter biologically because of the roles they play within systems capable of maintaining themselves across time.

Similarly, APS does not invoke mysterious holistic forces or organismic essences. Organisational properties are explanatorily relevant only insofar as they correspond to identifiable patterns of constraint, regulation, and viability maintenance with observable consequences for system persistence.

In this respect APS attempts to preserve the strongest explanatory insights of organicism while avoiding its historical ambiguities.

APS and Contemporary Organisational Biology

Several contemporary developments in theoretical biology have revived themes historically associated with organicism.

These include:

• organisational closure theory,
• autonomy theory,
• process philosophy of biology,
• developmental systems theory,
• enactivism,
• organism-centred evolutionary theory,
• systems biology.

APS shares important concerns with many of these approaches, particularly their emphasis on organisation, persistence, and organism-centred explanation.

At the same time APS attempts to integrate these concerns within a unified explanatory structure centred on viability-oriented organisation and scale-integrated persistence.

Rather than functioning solely as a metaphysical orientation or philosophical interpretation, APS aims to provide a coherent explanatory grammar for biological systems together with operational criteria capable of guiding empirical investigation.

Why APS Is Not Simply “Neo-Organicism”

APS is therefore not best understood as a revival of organicism in its historical form.

APS is not:

• a return to vitalism,
• a rejection of mechanistic explanation,
• a purely holistic philosophy,
• a vague appeal to organismic unity,
• a metaphysical doctrine about the nature of life.

Instead APS treats organisation as explanatorily significant because living systems actively maintain the conditions of their own persistence through organised and viability-oriented activity.

The explanatory importance of organisation therefore arises from the observable dynamics of self-maintaining systems rather than from abstract appeals to wholeness alone.

APS inherits from organicism the conviction that life cannot be understood through atomistic reduction alone. But it attempts to reconstruct this insight through explicit organisational principles, explanatory structure, and operational diagnostics.

In this sense APS belongs historically within the broader organism-centred traditions of biology while also moving beyond classical organicism toward a more precise theory of biological organisation itself.
