Natural Possibility 5 SNOOBIS and Medicine

This paper continues the Natural Possibility research programme developed in Papers 1–3 by extending its structural account of constraint and coherence into the domain of medicine. It introduces SNOOBIS (Structural Coherence Model of Living Systems) as a vertically structured model of biological viability. Health is reconceptualised not as mere compliance with biological law, but as sustained coherence across interdependent layers of organisation: Self, Natural, Organic, Organised, Biological, Intelligence, and Systems. Disease is interpreted as vertical desynchronisation within or between these layers rather than as a violation of natural constraints. The paper argues that medicine should be understood as the restoration of structural coherence under lawful limitation, with implications for pharmacology, diagnostics, medical technology, and mental health. SNOOBIS provides a structured framework for analysing stability and viability in living systems.
