Modern medicine and public health have achieved extraordinary gains in diagnosis, acute care, infectious disease control, surgery, and the treatment of organ-specific pathology. Yet the dominant health paradigm remains poorly equipped for the chronic, developmental, relational, ecological, commercial, and political-economic conditions that increasingly shape contemporary disease and suffering. Chronic illness, multimorbidity, mental distress, developmental vulnerability, ecological degradation, social fragmentation, digital disorientation, and health inequity cannot be adequately understood through the isolated individual body alone, nor by adding social determinants as external background factors.
This white paper proposes The Field of Viability Framework, a relational life-course model of health, well-being, and collective action. The framework defines health as the life-course viability of the developing person-in-field: the capacity to continue, recover, develop, relate, participate, and flourish under changing biological, relational, institutional, ecological, cultural, commercial, and political-economic conditions. Its core diagnostic engine is a seven-primitives viability grammar: constraints, margins, state, disturbance, perception, regulation, and options. These primitives provide a portable language for understanding how conditions preserve, erode, restore, or expand life-capacity across scales.
The framework integrates insights from biomedicine, biopsychosocial medicine, life-course health development, social determinants of health, commercial determinants, exposome science, allostasis and allostatic load, early relational health, interoception, syndemics, planetary health, systems thinking, civil commons theory, and implementation science. It reframes disease as a trajectory of narrowing viability, healing as restoration of viable coupling between person and field, prevention as life-field design, policy as field regulation, and governance as the coordination of coordination in service of life-capacity.
The Field of Viability Framework does not replace biomedical diagnosis or public-health evidence. It situates them within a wider relational model that links embodied physiology, lived experience, field conditions, condition-generating systems, and collective action. Its aim is to provide clinicians, public-health practitioners, researchers, policymakers, communities, and institutions with a shared grammar for coordinating healing, prevention, policy, research, and governance around the preservation and expansion of viable life.
