About this Book

This book introduces, explains, and critically evaluates major theories of consciousness. It is designed for an academic audience and is organized around the central question: How, if at all, can consciousness be explained scientifically, philosophically, computationally, physically, phenomenologically, or through consciousness-first frameworks?

The book dedicates major chapters to individual theories or families of theories. Each chapter examines historical development, core assumptions, explanatory framework, empirical support, strengths, weaknesses, unresolved gaps, and the theory’s ability to address central problems such as subjective experience, reportability, selfhood, attention, neural correlates, altered states, animal consciousness, and artificial intelligence.

The book also includes comparative and integrative chapters that examine how the theories relate to one another, which problems they clarify, which problems remain unresolved, and whether consciousness can ultimately be scientifically explained.

In addition to mainstream neuroscientific, computational, philosophical, and physical theories, the book also discusses consciousness-first frameworks, including panpsychism, cosmopsychism, and Taheri’s T-Consciousness, as part of the broader debate about whether consciousness is produced by matter, emerges from complexity, or is foundational to reality.

0.2 Suggested Citation Style

The default bibliography uses an author-date academic style through references.bib and apalike. This can be replaced with APA 7, Chicago Author-Date, or another CSL style if desired.

Notes for Readers

This book is a developing academic project. Theories of consciousness remain actively debated, and no single framework currently explains all dimensions of consciousness. The aim of this book is therefore not to present one final answer, but to provide a structured, comparative, and interdisciplinary guide to the major approaches, their contributions, and their unresolved challenges.
