Then I Am Myself the World: What Consciousness Is and How to Expand It Hardcover – May 7, 2024
Purchase options and add-ons
The world’s leading investigator of consciousness argues that by understanding what consciousness does—cause change in the world—we can understand its origins and its future
In Then I Am Myself the World, Christof Koch explores the only thing we directly experience: consciousness. At the book’s heart is integrated-information theory, the idea that the essence of consciousness is the ability to exert causal power over itself, to be an agent of change. Koch investigates the physical origins of consciousness in the brain and how this knowledge can be used to measure consciousness in natural and artificial systems.
Enabled by such tools, Koch reveals when and where consciousness exists, and uses that knowledge to confront major social and scientific questions: When does a fetus first become self-aware? Can psychedelic and mystical experiences transform lives? What happens to consciousness in near-death experiences? Why will generative AI ultimately be able to do the very thing we can do, yet never feel any of it? And do our experiences reveal a single, objective reality?
This is an essential book for anyone who seeks to understand ourselves and the future we are creating.

Review
“a fun introduction to a number of debates… Mr. Koch’s book provokes questions… and counterarguments, but that’s what gives it life.” ―The Wall Street Journal
“Easily the most current, thorough, and helpful exploration of consciousness available. Koch’s light, simple, yet authoritative writing style will appeal to general audiences as well as scientists and researchers. An essential, highly recommended purchase.”―Library Journal
“magisterial… charming, sometimes beautiful, and almost always illuminating”
―Science Magazine
“an impressive and sometimes exuberant work, showcasing decades of [Koch’s] research”―New Scientist
“Koch’s adept use of analogies and entertaining anecdotes — complete with his own near-death experience and psychedelic drug trips — make the book a compelling and surprisingly light read.” ―Science News
“undeniably compelling… a smoothly written must-read for anyone interested in a detailed introduction to the relationship between the brain, consciousness, and transformative experiences”
―Ars Technica
“Expertly weaving in personal experience with science that few, if any, can speak more authoritatively about, Koch leads us on an amazing journey of consciousness—from birth to death. Deeply personal and infinitely digestible, Then I Am Myself the World is a remarkable must read for anyone interested in knowing their mind.”―Judson Brewer MD, PhD, New York Times–bestselling author of Unwinding Anxiety
“Koch’s latest book brilliantly navigates the intricate landscape of our mind and our brain, offering insightful perspectives on the nature of conscious experiences, both ordinary as well as extraordinary ones.”―Hartmut Neven, founder and lead of Google’s quantum AI lab
“Then I Am Myself the World is the new record of note for the scientific understanding of consciousness. This is an elegant tableau, a travelogue of subjective experience grounded in the latest neuroscience and philosophy traversing religion, science, and a life dedicated to the biggest questions. Filled with crystalline prose, lucid explanation, and revelatory honesty, this book will continue to be read centuries from now.”―Patrick House, author of Nineteen Ways of Looking at Consciousness
“What would happen if a hardcore neuroscientist, with encyclopedic knowledge and four decades of experience in his field, were personally confronted with transformative mystical experiences carrying inevitable metaphysical implications? What would happen if the neuroscientist in question were open-minded, humble, but remained rigorously grounded in reason, evidence, and his hard-earned understanding of how consciousness relates to brain structures and function? What would he, the most preeminent professional of his generation, make of his extraordinary experiences? And what if, in addition, the neuroscientist was a modern renaissance man versed in physics, philosophy, the arts, the classics, and could pluck irresistibly evocative metaphors from the Western literary and artistic canon as if leisurely picking apples in early fall? This is what you will find in this treasured book, a whirlwind ride of insight after insight—so many they can’t possibly be all documented in footnotes—that will surprise and delight you from the get-go. ‘Primacy goes to consciousness, not to the objective world,’ he boldly states already on page two, in a prelude of things to come. ‘Everything else follows from there, including the realist assumption of the existence of objects, out ‘there,’ independent of my experiencing them.’ The book embodies the ever-evolving wisdom of a man whose intellectual prowess is only matched by his intellectual honesty. And this man, in the seventh decade of his scintillatingly productive life, has a lifetime of learning to share with you.”―Bernardo Kastrup, executive director, Essentia Foundation
“Koch’s first book was entitled The Quest for Consciousness. And such has been Koch’s life, an adventurer’s pursuit of a distant goal, undeterred by the prevailing winds. The reader will learn where this quest has led and, like the author, will be enriched by it. Koch, one of the most accomplished scientists of our time, a mind singularly open to learning and changing, here opens his soul, revealing his vast, scintillating appreciation of nature in all its forms. It is a touching, profound book. Which is as it should be, since consciousness touches everything and is everything we touch.”―Giulio Tononi, University of Wisconsin-Madison

- Reviewed in the United States on August 20, 2024I really enjoyed this book. Koch does a great job defining consciousness as the experience of awareness, of that feeling inside, that inner world we have. It makes sense that all animals too would have some version and level of this. This is a fascinating read, well thought out, and written. It makes a lot of sense to me, more so than some other theories of consciousness.
- Reviewed in the United States on August 1, 2024A friendly, quick read that doesn't in the end add up to a whole lot -- a bit disappointing given Koch's central place in the neuroscientific side of consciousness studies. But then, profound experiences often elude deep description, let alone detailed working out of their fuller implications. At least he sets an example, as a scientist of stature, in not being afraid of open approaches to huge questions.
- Reviewed in the United States on October 9, 2024First of all I want to say that this is just a great book. Through a clear and pleasant writing, it covers so many subjects with a general unbiased approach (alternative views are always reported, and the opinion of the author clearly stated). The concept of integrated information theory and causal power is fascinating and getting to new unexplored frontiers, even its axioms and postulates feels a lot like a self sustaining thought. More work to be done! This is the first book I read from Prof. Koch, but certainly not the last!
- Reviewed in the United States on May 13, 2024I finished this book last night. What a wonderful read! Chapters 4 and 5 were exemplary in their clarity, while Chapters 6 and 7 were a remarkable contribution to the nascent scientific exploration of mystical and psychedelic states. Combine all this with a vigorous style and a knack for finding just the right metaphor, and you have the makings of a classic. There is much to cheer about here!
- Reviewed in the United States on October 24, 2024Thoroughly enjoyed this book. The facts of consciousness were identified without judgement of a person's beliefs leaving the reader to conclude what they may.
- Reviewed in the United States on August 22, 2024I read this book after reading a review in Science News that intrigued me. I have a thesis of my own, regarding Life as a function similar to this concept of consciousness. Koch’s descriptions provide some substance for me to expand my own thoughts.
- Reviewed in the United States on May 24, 2024Koch is a fantastic thinker, and he jumps here from explaining consciousness, using Giulio Tononi’s excellent model, to proclaiming that conscious entities must have free will. That, to me, is a bridge too far.
I also do not see how engineered objects such as computers differ fundamentally from evolved objects such as humans. The difference is one of degree, not of substance. Koch himself even implies this - even as he seems to deny it.
I still find his/Tononi’s integrated information theory of consciousness to be most compelling. I just don’t see how it necessarily contradicts the possibility of engineered, conscious, determined entities. I would love to see him discuss this with Sam Harris. Perhaps he already has?
- Reviewed in the United States on May 22, 2024Dr. Koch has been at the forefront of the study of consciousness for 30 years, and has distilled his wealth of knowledge into a straightforward and easy to understand book. Not only does Dr. Koch make complicated topics feel tangible, he also does an excellent job of demonstrating how these ideas effect us every single day and with everything that we do.
