This book introduces The Coherent Human, a comprehensive theory that proposes rebuilding human science around the principle of systemic integration. The author argues that modern medicine and psychology are overly fragmented, treating isolated symptoms rather than the energetic, temporal, and biological roots of human experience. By shifting focus toward coherence, the framework explores how the alignment of metabolism, autonomic regulation, and predictive brain models creates a foundation for health. The sources detail how disruptions in these systems manifest as trauma, chronic illness, and existential crisis, while restoration leads to genuine flourishing. Ultimately, the text extends these biological principles to leadership, culture, and civilization, suggesting that collective stability depends on shared coherence. This unified model redefines healing as the reintegration of the whole person across scales of energy, time, and meaning.
