Description, Explanation, and Definition in Biology — An APS Clarification

Introduction

Biology relies heavily on ordinary language.

Organisms are said to:

  • pursue goals
  • possess functions
  • follow norms
  • adapt to survive
  • regulate themselves
  • operate at higher and lower levels

Such language is often useful, efficient, and entirely appropriate within ordinary biological practice.

Problems arise, however, when descriptive language is silently transformed into explanatory or definitional claims without clarification of the organisational assumptions involved.

APS therefore distinguishes between:

  • description
  • explanation
  • definition

This distinction is not primarily linguistic.

It is explanatory.

The framework does not attempt to police vocabulary or eliminate ordinary biological language. Rather, APS attempts to clarify the organisational conditions under which biological explanations become coherent as biological explanations.

In this respect the distinction between description, explanation, and definition becomes part of the broader explanatory grammar of APS itself.

Descriptive Language

Descriptive language reports observable patterns, behaviours, structures, or outcomes.

For example:

  • “The organism survives.”
  • “This structure has a function.”
  • “The system behaves as if it has a goal.”
  • “The organism regulates its internal environment.”
  • “There are higher and lower levels of organisation.”

Such statements may be entirely reasonable descriptions of biological phenomena.

By themselves, however, they do not explain:

  • what makes the system living
  • how the behaviour is organised
  • what grounds the function
  • why the activity exhibits goal-directed organisation
  • or what organisational relations sustain the observed patterns

Description identifies patterns.

Explanation identifies the organisational conditions under which those patterns become possible.

This distinction is important because descriptive language often carries implicit explanatory suggestions. Terms such as function, goal, regulation, adaptation, signalling, or control may appear descriptively harmless while silently implying deeper assumptions concerning agency, causation, normativity, or organisation.

APS therefore does not reject ordinary descriptive language. It clarifies what must be organisationally true for such descriptions to become explanatorily meaningful.

Explanatory Language

Explanation concerns the organisational conditions under which biological phenomena occur.

At this level, language carries explanatory and ontological commitments.

For example:

  • “The organism survives because it wants to survive.”
  • “Function explains the behaviour.”
  • “Norms guide the system.”
  • “Higher levels control lower levels.”
  • “The system stores information in order to achieve goals.”

In such cases, familiar terms are no longer acting merely as descriptive shorthand. They are being used to explain biological organisation itself.

APS intervenes at precisely this point.

The framework asks:

What organisational conditions make these explanatory claims meaningful?

This shift is central to the APS approach.

Rather than treating goals, functions, norms, information, or regulation as self-explanatory entities, APS attempts to re-anchor explanation in viability-oriented organised persistence.

Goals become intelligible through viability-oriented organisation. Functions become intelligible through contribution to organised persistence. Norms become intelligible through viability-relative asymmetries. Regulation becomes intelligible through the active modulation of organisation relative to viability conditions. Meaning becomes intelligible through evaluative semiosis.

APS therefore changes not the empirical content of biology, but the organisational grounding of biological explanation itself.

Definitional Language

Definitions specify what kind of thing something is.

This level is especially important because definitions establish the conceptual boundaries within which explanation operates.

Examples include:

  • “Life is reproduction.”
  • “Agency is behavioural responsiveness.”
  • “Normativity is rule-following.”
  • “Function implies purpose.”
  • “Information processing defines cognition.”

APS is explicitly a definitional framework.

The framework therefore treats definitional precision as philosophically significant rather than merely terminological.

Definitions determine how distinctions are drawn between:

  • life and non-life
  • agency and passive behaviour
  • biological normativity and external evaluation
  • cognition and mere responsiveness
  • organisation and aggregation

For this reason, definitional language requires greater precision than ordinary descriptive use.

APS does not assume that familiar biological terms automatically possess stable explanatory meaning. It asks what organisational conditions must exist for those definitions to apply coherently in the first place.

Category Drift

Many conceptual confusions in biology arise through what APS describes as category drift.

Category drift occurs when:

  • descriptive shorthand becomes explanatory mechanism
  • outcomes are treated as causes
  • abstractions are treated as organisational realities
  • heuristic models become implicit ontology
  • analytic distinctions become ontological divisions

Examples include:

  • treating goals as causes rather than descriptions of viability-oriented organisation
  • treating functions as intentions rather than contributions to persistence
  • treating norms as external rules rather than viability-relative asymmetries
  • treating levels as ontological strata rather than analytic partitions of scale
  • treating information as intrinsically meaningful independently of organisational context

These shifts often occur gradually and without explicit acknowledgement.

Conceptual language that initially functions as useful shorthand may slowly acquire explanatory force it was never originally intended to bear.

APS attempts to stabilise biological explanation by continuously returning explanatory claims to organisation itself.

Why APS Does Not Reject Ordinary Language

APS does not attempt to abolish ordinary biological terminology.

Scientists and ordinary speakers will continue to use terms such as:

  • goal
  • function
  • adaptation
  • survival
  • regulation
  • information
  • control

The framework does not object to such usage descriptively.

APS intervenes only when descriptive language is promoted into explanatory or definitional claims without clarification of the organisational assumptions involved.

Calling a system “whole,” “integrated,” or “organismic” may describe an important feature of life, but such terms do not yet explain biological organisation. APS therefore distinguishes descriptive appeals to wholeness from explanatory accounts of how viability-oriented organisation is continuously maintained across process and scale.

The issue is therefore not vocabulary itself.

It is explanatory grounding.

APS preserves ordinary language for communication while requiring conceptual precision where explanatory commitments are being made.

This distinction allows the framework to remain compatible with ordinary scientific practice while still clarifying the organisational architecture underlying biological explanation.

Organisation Rather Than Outcomes

A recurring principle within APS is that explanation must be grounded in organisation rather than outcomes alone.

Outcomes may identify what occurred. They do not necessarily explain how organised persistence was achieved.

For example:

  • survival does not explain persistence unless the organisation sustaining viability is specified
  • function does not explain behaviour unless contribution to organised persistence is clarified
  • adaptation does not explain biological change unless reorganisation across time is identified
  • information does not explain regulation unless the organisational context rendering differences meaningful is specified

APS therefore shifts explanation away from retrospective outcome description and toward the organised processes through which living systems continuously sustain themselves.

This shift is one reason APS increasingly functions as an explanatory grammar rather than merely a conceptual vocabulary.

Explanation becomes constrained not simply by observable outcomes, but by the organisational conditions required for viability-oriented persistence.

Why This Matters

The distinction between description, explanation, and definition matters because biology routinely moves between these modes without making the transitions explicit.

As a result:

  • descriptive shorthand may acquire unintended ontological force
  • metaphors may harden into mechanisms
  • explanatory assumptions may become embedded implicitly within theory
  • heuristic models may be mistaken for organisational explanation

APS attempts to make these transitions visible.

This is not terminological rigidity.

It is an attempt to preserve explanatory coherence across agency, process, scale, normativity, semiosis, cognition, adaptation, and evolution.

The broader goal is therefore methodological as much as philosophical.

APS attempts to clarify the organisational conditions under which biological explanation remains coherent, integrated, and biologically grounded.

Conclusion

Ordinary biological language is often descriptively useful while remaining explanatorily indeterminate.

APS distinguishes descriptive, explanatory, and definitional uses of biological language in order to clarify what organisational conditions biological explanations presuppose.

The framework therefore does not reject familiar terminology. It clarifies the explanatory commitments carried by that terminology when it is used to explain or define living systems.

Many conceptual confusions arise not from ordinary language itself, but from unnoticed transitions between description, explanation, and definition.

APS seeks to stabilise those transitions by re-anchoring biological explanation in viability-oriented organised persistence.

In this respect, the distinction between description, explanation, and definition is not merely semantic.

It is part of the explanatory architecture required for living systems to become intelligible as living systems at all.

Key Point

APS distinguishes descriptive, explanatory, and definitional uses of biological language in order to stabilise biological explanation and re-anchor explanatory meaning in viability-oriented organisation rather than outcomes, abstractions, or metaphorical shorthand.
