Despite sustained advances in neuroscience, psychiatry, philosophy of mind, and artificial intelligence, subjective experience — qualia — remains resistant to explanation. Traditional approaches frame consciousness as something produced by physical processes, leaving an apparent explanatory gap between third-person descriptions and first-person experience.
This book proposes a reframing. Rather than treating consciousness as an emergent output, it argues that qualia are the interior face of viability wherever a system must preserve its own coherence under uncertainty through lossy interfaces. From this perspective, experience is not mysterious but inevitable: it arises when regulation cannot be further reduced without loss of function.
Integrating affective neuroscience, predictive processing, psychiatry, philosophy of mind, and ancient interior sciences such as Daoism, Traditional Chinese Medicine, and Ayurveda, the book develops a unified interface-based framework in which emotional sentience precedes cognition, affect grounds consciousness, and meaning emerges through layered projections. Competing theories — ranging from affective and constructionist models of emotion to active inference and the hard problem of consciousness — are re-situated at distinct interface depths rather than forced into premature synthesis.
The result is a rigorously naturalistic account that preserves the irreducibility of experience without invoking metaphysical dualism or reductionism. By locating qualia at the intersection of regulation, uncertainty, and intrinsic value, the framework offers new clarity for neuroscience, psychiatry, philosophy, and the ethics of artificial systems.
