Executive Summary
The Problem
Across disciplines, systems fail in ways that are:
- Sudden yet preceded by subtle signals
- Resistant to prediction despite abundant data
- Often worsened by well-intentioned interventions
Examples include:
- Clinical deterioration in patients who initially appear stable
- Ecosystem collapse following incremental degradation
- Financial crises emerging from prolonged periods of apparent stability
These patterns suggest that failure is not primarily a problem of missing data, but of missing structure.
The Gap
Current approaches tend to:
- Focus on isolated variables rather than relationships
- Emphasize prediction and control over adaptability
- Miss early signs of failure because coherence is not directly measured
As a result, systems may appear stable while their underlying structure degrades.
The Proposal
This work introduces a minimal grammar of viability, consisting of seven primitives:
- State (X) — current system condition
- Constraints (C) — boundaries of viability
- Margins (M) — capacity to absorb disturbance
- Disturbances (D) — forces acting on the system
- Perception (P) — interpretation of system and environment
- Regulation (R) — actions taken in response
- Options (O) — available pathways for adaptation
These elements are organized into seven triads, forming a closed relational structure mapped to the Fano plane.
The Structure
The framework operates across three levels:
- Local (ω — Pairwise Compatibility)
Determines which interactions are structurally permissible
- Meso (N₃ — Triadic Coherence)
Determines whether interactions form coherent relational units
- Global (I₄ — System Viability)
Determines whether the system can persist as a whole
Failure at any level can propagate across the system.
The Shift
The central shift proposed is:
From control → to navigation
Instead of attempting to predict and control outcomes, systems should:
- Operate within constraints
- Preserve margins and optionality
- Adapt to disturbances through coherent transitions
Mathematics, in this context, becomes a tool for mapping viable transitions, not predicting exact futures.
Applications
Clinical Medicine
- Avoiding iatrogenic harm
- Preserving physiological reserve
- Knowing when not to intervene
- Maintaining flow networks
- Preserving biodiversity and redundancy
- Supporting adaptive capacity
Economics & Governance
- Avoiding overregulation
- Preserving optionality
- Recognizing structural sources of fragility
Key Insight
Across all domains:
Stability is not the absence of change, but the preservation of coherence across change.
The Principle
The work culminates in a single guiding statement:
Systems remain viable by navigating the space of possibilities within constraints.
Implication
This framework provides:
- A shared language across disciplines
- A diagnostic tool for early detection of failure
- A practical guide for decision-making under uncertainty
It shifts attention from:
- Outcomes → to structure
- Control → to coherence
- Prediction → to navigation
The Seven Primitives of the Geometry of Viability
Please scroll to the right to see the right columns| Primitive Name | Symbol | Functional Role | Description | Triadic Participation (Inferred) |
|---|---|---|---|---|
| State | Realized Configuration | The current configuration of the system, representing its position in state space and the point from which all transitions occur. | 3 | |
| Constraints | Defining the Space of Possibility | The boundaries within which the system must operate; structured absences that define what is not possible to shape what is possible. | 3 | |
| Margins | Buffering and Resilience | The available buffer or capacity (physiological reserves, redundancy, liquidity) to absorb disturbances without losing coherence. | 3 | |
| Disturbances | Driving Change | External or internal perturbations or forces acting upon the system that challenge stability and test resilience. | 3 | |
| Perception | Informational Interface | The capacity to detect and interpret states and disturbances, functioning as a transformative interface between constraints and options. | 3 | |
| Regulation | Coordinated Response | The mechanisms, feedback loops, and adaptive strategies by which a system responds to maintain or restore coherence. | 3 | |
| Options | Adaptive Potential | The set of possible pathways or transitions available (the adjacent possible) for adaptation and navigating the state space. | 3 |
