Existence, Alignment, and Sustainability A Dual-Singularity Model of Human Psychological Life

Psychological theory and clinical models often privilege either biological regulation or meaning-based constructs without structurally integrating them. Consequently, sustained psychological functioning across time is frequently explained through symptom reduction, insight, or narrative coherence, despite evidence that these outcomes alone do not ensure continuity or engagement. This paper proposes a dual-singularity model identifying two minimally sufficient anchoring conditions for psychological continuation: existence (embodied biological continuity and regulatory capacity) and alignment sustained through time (self-directed organization enacted under real conditions). Psychological health is reconceptualized as the ongoing coordination between these anchors rather than as equilibrium, symptom absence, or meaning alone. The model is architectural and descriptive. It does not specify mechanisms, values, or therapeutic procedures. Its function is to clarify minimal structural conditions required for sustained psychological life across time, drawing on convergent findings from systems theory, stress physiology, trauma research, and transdiagnostic process models.
