Synopsis

Self Comes to Mind Explores two questions that have haunted philosophers, neurologists, cognitive scientists and psychologists for centuries: how do brains construct minds, and how do minds become conscious. This book reveals how our minds work - often without knowing or even controlling what we do - and allow us to glimpse the root of our fondest constructs. Full description

 Awakening
 
When I woke up, we were descending. I had been asleep long enough to miss the announcements about the landing and the weather. I had not been aware of myself or my surroundings. I had been unconscious.
 
Few things about our biology are as seemingly trivial as this com­modity known as consciousness, the phenomenal ability that consists of having a mind equipped with an owner, a protagonist for one’s exis­tence, a self inspecting the world inside and around, an agent seemingly ready for action.
 
Consciousness is not merely wakefulness. When I woke up, two brief paragraphs ago, I did not look around vacantly, taking in the sights and the sounds as if my awake mind belonged to no one. On the con­trary, I knew, almost instantly, with little hesitation if any, without effort, that this was me, sitting on an airplane, my flying identity com­ing home to Los Angeles with a long  to-do list before the day would be over, aware of an odd combination of travel fatigue and enthusiasm for what was ahead, curious about the runway we would be landing on, and attentive to the adjustments of engine power that were bringing us to earth. No doubt, being awake was indispensable to this state, but wake­fulness was hardly its main feature. What was that main feature? The fact that the myriad contents displayed in my mind, regardless of how vivid or well ordered, connected with me, the proprietor of my mind, through invisible strings that brought those contents together in the forward-moving feast we call self; and, no less important, the fact that the connection was felt. There was a feelingness to the experience of the connected me.
 
Awakening meant having my temporarily absent mind returned, but with me in it, both property (the mind) and proprietor (me) accounted for. Awakening allowed me to reemerge and survey my mental domains, the sky-wide projection of a magic movie, part documentary and part fiction, otherwise known as the conscious human mind.
 
We all have free access to consciousness, bubbling so easily and abun­dantly in our minds that without hesitation or apprehension we let it be turned off every night when we go to sleep and allow it to return every morning when the alarm clock rings, at least 365 times a year, not counting naps. And yet few things about our beings are as remarkable, foundational, and seemingly mysterious as consciousness. Without consciousness—that is, a mind endowed with subjectivity—you would have no way of knowing that you exist, let alone know who you are and what you think. Had subjectivity not begun, even if very modestly at first, in living creatures far simpler than we are, memory and reasoning are not likely to have expanded in the prodigious way they did, and the evolutionary road for language and the elaborate human version of con­sciousness we now possess would not have been paved. Creativity would not have flourished. There would have been no song, no paint­ing, and no literature. Love would never have been love, just sex. Friendship would have been mere cooperative convenience. Pain would never have become suffering—not a bad thing, come to think of it— but an equivocal advantage given that pleasure would not have become bliss either. Had subjectivity not made its radical appearance, there would have been no knowing and no one to take notice, and conse­quently there would have been no history of what creatures did through the ages, no culture at all.
 
Although I have not yet provided a working definition of conscious­ness, I hope I am leaving no doubt as to what it means not to have con­sciousness: in the absence of consciousness, the personal view is sus­pended; we do not know of our existence; and we do not know that anything else exists. If consciousness had not developed in the course of evolution and expanded to its human version, the humanity we are now familiar with, in all its frailty and strength, would never have developed either. One shudders to think that a simple turn not taken might have meant the loss of the biological alternatives that make us truly human. But then, how would we ever have found out that something was missing?
 
We take consciousness for granted because it is so available, so easy to use, so elegant in its daily disappearing and reappearing acts, and yet, when we think of it, scientists and nonscientists alike, we do puzzle. What is consciousness made of? Mind with a twist, it seems to me, since we cannot be conscious without having a mind to be conscious of. But what is mind made of? Does mind come from the air or from the body? Smart people say it comes from the brain, that it is in the brain, but that is not a satisfactory reply. How does the brain do mind?
 
The fact that no one sees the minds of others, conscious or not, is especially mysterious. We can observe their bodies and their actions, what they do or say or write, and we can make informed guesses about what they think. But we cannot observe their minds, and only we our­selves can observe ours, from the inside, and through a rather narrow window. The properties of minds, let alone conscious minds, appear to be so radically different from those of visible living matter that thoughtful folk wonder how one process (conscious minds working) meshes with the other process (physical cells living together in aggre­gates called tissues).
 
But to say that conscious minds are mysterious—and on the face of it they are—is different from saying that the mystery is insoluble. It is dif­ferent from saying that we shall never be able to understand how a liv­ing organism endowed with a brain develops a conscious mind.

Revue de presse :

"Exquisite...Readers fascinated from both a philosophical and scientific perspective with the question of the relationship among brain, mind, and self will be rewarded."
—Publishers Weekly

"The marvel of reading Damasio's book is to be convinced one can follow the brain at work as it makes the private reality that is the deepest self."
—V.S. Naipaul, Nobel Laureate and author of A Bend in the River and the Enigma of Arrival

“Damasio makes a grand transition from higher-brain views of emotions to deeply evolutionary, lower-brain contributions to emotional, sensory and homeostatic experiences. He affirms that the roots of consciousness are affective and shared by our fellow animals. Damasio's creative vision leads relentlessly toward a natural understanding of the very font of being.”
—Jaak Panksepp, author of Affective Neuroscience and Baily Endowed Professor of Animal Well-Being Science, Washington State University 

 “I was totally captivated by Self Comes to Mind.  In this work Antonio Damasio presents his seminal discoveries in the field of neuroscience in the broader contexts of evolutionary biology and cultural development. This trailblazing book gives us a new way of thinking about ourselves, our history, and the importance of culture in shaping our common future.”
—Yo-Yo Ma, musician

“The epicenter of Self Comes to Mind concerns the neurological basis for cognition and the issue of the superposition of a “self’ onto the construct which we address as reality. In very characteristic style, Antonio is both eloquent and scholarly. His command of the themes he approaches is impressive, as is the vigor with which he tackles such recondite issues as the elusive “self,” inside the head. A wonderful read, and a recommended one!”
—Rodolfo R. Llinás, Chair and Professor of Physiology and Neuroscience, New York University

“In this astonishing work, Antonio Damasio puts his years of investigation into the processes of the brain to open the impenetrable mysteries of self and mind, where all the contradictions of human experience unite in the ultimate unknown, consciousness.”
—Peter Brook, theater and film director and author of The Empty Space and Threads of Time

“Awareness may be mostly mystery, but Damasio shapes its hints and glimmerings into an imaginative, informed narrative.”
—Kirkus  

“A thoughtful work.”
—Scientific American Book Club
 
“A very interesting book...cogent, painstaking, imaginative, knowledgeable, honest, and persuasive...Damasio’s quest is both thorough and comprehensive”
—New York Journal of Books

“Ambitious...a lucid and important work.” –Wired.com

“Self Comes to Mind is a Big Idea book penned by a luminous thinker...The result is this beautifully sprawling and marvelous work.” –The Dallas Morning News

“[Damasio] writes with such flair and confidence that it is almost as if he makes the mystery dissolve into knowledge before our eyes...a compelling picture, once one sets aside the power of the unconscious, and of grasping, other-hating, defensive, anxious, ideologically-motivated consciousness...what one has to applaud is the imaginative vision Damasio brings to the task.” –Barnes and Noble Review
 
“Intriguing...introduces some novel ideas.” –New Scientist

“An important and impressive study.” –The Magonia Blog and Magonia Review of Books

“I found Self Comes to Mind a delight...an intellectual journey well worth the effort.” –Wilson Quarterly
