Modern civilization governs itself through a performance grammar that equates output, productivity, and economic growth with progress. This white paper demonstrates that this semantic architecture, when applied to living systems, is biologically incoherent and structurally dangerous. Drawing on regulatory biology, stress physiology, life-course health, ecological resilience, and development economics, the paper shows that performance is a transient expression of stored capacity, not a measure of system health. When performance is elevated to the master variable of governance — as occurs through GDP-centered policy and Sustainable Development Goal 8 — societies reproduce at planetary scale the same pathological dynamics that generate chronic disease, burnout, and organ failure in individual bodies: chronic stress without sufficient recovery. The paper critiques GDP as a throughput metric incapable of registering biological and ecological depletion, analyzes the internal contradiction embedded within SDG 8, and proposes a post-performance metric grammar grounded in recovery capacity, intrinsic health, functional realization, and intergenerational reserve. It argues that the central task of 21st-century governance is semantic before it is technical: to reinstall capacity over output, recovery over throughput, and life-course solvency over quarterly performance. Only through this reversal can development be reconciled with health, and economics with biology.
