\"The<\/a><\/p>\n

There is a thought experiment known as Mary\u2019s Room<\/a>, brilliant and haunting, about the abyss between felt experience and our mental models of it, about the nature of knowledge, the mystery of consciousness, and the irreducibility of aliveness: Living in a black-and-white chamber, Mary the scientist studies how nature works \u2014 from the physics of light to the biology of the eye \u2014 but when she exits her monochrome room and encounters color, she experiences something far beyond her knowledge of what color is. It might be impossible, the experiment intimates, to imagine \u2014 even with our finest knowledge and best predictive models \u2014 what an experience would feel like before we have it, raw and revelatory and resinous with the one thing we can never model, never reduce to information: wonder \u2014 the wonder of the world suddenly new and we suddenly new to ourselves.<\/p>\n

Neurobiologist Susan R. Barry was in her fifties when she realized she had been living in Mary\u2019s Room.<\/p>\n

Born cross-eyed and stereoblind \u2014 unable to form three-dimensional images the way most people do as we aim our two eyes in the same direction, combining the visual input in the brain \u2014 Barry had undergone a number of corrective eye-muscle surgeries as a child, which made her eyes appear aligned. She was told she was cured, able to do anything people with normal vision do except fly an airplane. <\/p>\n

It was not until her junior year of college that, listening to a lecture about the visual cortex and ocular dominance columns, she learned about monocular and binocular vision. She was astonished to realize that she had gone through life lacking the latter \u2014 the kind most people have, which allows us to see in stereo. She accepted her condition and went on living with the lens chance had dealt her. But by midlife, her eyes had grown even more misaligned, both horizontally and vertically. She learned about a kind of vision therapy involving a set of prism glasses and some impressively inventive eye-training exercises. It was transformative. Paintings began to look more three-dimensional and she could see \u201cthe empty, yet palpable, volumes of space between leaves on tree.\u201d She recounts:<\/p>\n

\n

Over the next several months, my vision was completely transformed. I had no idea what I had been missing. Ordinary things looked extraordinary. Light fixtures floated and water faucets stuck way out into space.<\/p>\n<\/blockquote>\n

Three years into relearning to see, she met Oliver Sacks<\/a> at her astronaut husband\u2019s space shuttle launch. With his passionate curiosity about the interplay of physiology and psychological reality, the famed neurologist asked her a question that came to haunt her: Could she imagine what the world would look like viewed with two eyes? <\/p>\n

As a neurobiology professor herself, having written and read countless papers on visual processing, binocular vision, and stereopsis, Barry was at first certain she could. But the more she thought about the question, the more she felt into it, the more she realized that something essential was missing from her cerebral understanding: She was Mary, and the world was the world. <\/p>\n

Discomposed by the implications of the question, she decided to reach out to the questioner \u2014 for orientation, for consolation, for collaborative reckoning with this suddenly exposed facet of the confusion of consciousness. \u201cThat is my story,\u201d she wrote at the end of the nine-page letter detailing her unusual vision history. \u201cIf you have the time and inclination, I would greatly appreciate your thoughts. And, of course, I eagerly await your next book.\u201d <\/p>\n

Within days, Oliver had written back. Amazed at her defiance of the odds \u2014 it had long been accepted that binocular vision must be achieved by a \u201ccritical age\u201d or will forever elude the seer \u2014 he expressed his admiration for her willingness to welcome her \u201cnew world\u201d with such \u201copenness and wonder.\u201d So began their decade-long correspondence, which helped Barry \u201cshape a new identity.\u201d This richly nourishing epistolary friendship, which lasted until his death, now lives on in her wonderful part-memoir, part-memorial Dear Oliver<\/em><\/strong><\/a> (public library<\/em><\/a>).<\/p>\n

From her very first letter, she sets out to convey the wonder-filled disorientation of her newly trained vision \u2014 a transformation both life-expanding and overwhelming, given the coevolution of vision and consciousness<\/a>. She writes:<\/p>\n

\n

Imagine a person who saw only in shades of gray suddenly able to see in full color. Such a person would probably be overwhelmed by the beauty of the world. Could they stop looking? Each day, I spend time looking head-on at objects \u2014 flowers, my fingers, faucets, anything \u2014 in order to get that strong three-dimensional sense\u2026 After almost three years, my new vision continues to surprise and delight me. One winter day, I was racing from the classroom to the deli for a quick lunch. After taking only a few steps from the classroom building, I stopped short. The snow was falling lazily around me in large, wet flakes. I could see the space between each flake, and all the flakes together produced a beautiful three-dimensional dance. In the past, the snow would have appeared to fall in a flat sheet in one plane slightly in front of me. I would have felt like I was looking in on the snowfall. But, now, I felt myself within the snowfall, among the snowflakes. Lunch forgotten, I watched the snow fall for several minutes, and, as I watched, I was overcome with a deep sense of joy. A snowfall can be quite beautiful \u2014 especially when you see it for the first time.<\/p>\n<\/blockquote>\n

Barry\u2019s question about whether one could be so overwhelmed by a new way of seeing as to stop looking is not rhetorical \u2014 the history of medicine is strewn with cases<\/a> of blind people receiving corrective surgery that grants them sight, only to reject the new reality of light and return to the familiar world of darkness, moving through their lives with eyes shut. <\/p>\n

These physiological transformations are a haunting analogue for our psychological pitfalls \u2014 accepting change, even toward something that deepens and broadens our experience of aliveness, is never easy, in part because we are so poor at picturing<\/a> an alternate rendering of reality. \u201cThe things we want are transformative,\u201d Rebecca Solnit wrote in her superb Field Guide to Getting Lost<\/em><\/a>, \u201cand we don\u2019t know or only think we know what is on the other side of that transformation.\u201d We live so often lost in our frames of reference, lulled by the familiar, too terrified to live a larger life on the other side of a transformation that upends our comfortable ways of seeing and of being. (And what is the self if not just a style of being?) It takes both great courage and great vulnerability to welcome such a change \u2014 a transformation often mired in uncertainty, discomfiture, and confusion as we adapt to the overwhelm of life more magnified; a transformation that asks us to begin again, and a beginning always places a singular strain on the psyche<\/a>.<\/p>\n

Years into their correspondence, Barry shares with Oliver the case of a young woman who embodied this courageous willingness to welcome transformation \u2014 a student of hers born with almost no hearing, who had received a cochlear implant at age 12. Barry writes:<\/p>\n

\n

When her implant was first turned on, she did not recognize a sound as a sound but rather as a terrifying, unpleasant, unnerving feeling. For the first few days, she had this same frightening sensation every time she put on the implant. Eventually, she said, she came to accept the feeling. Then she began to expect the sensations and to interpret some of them as meaningful sounds.<\/p>\n

[\u2026]<\/p>\n

I was intrigued by her use of the word \u201caccept,\u201d because I think anyone who goes through a substantial perceptual improvement must learn to tolerate a certain amount of discomfort, uncertainty, and confusion. If one doesn\u2019t have the support of doctors, therapists, family, and\/or friends, then one may not allow the changes to occur.<\/p>\n<\/blockquote>\n

The degree to which we allow transformation \u2014 whether it comes in the form of new prism glasses or a new cochlear implant or a new love \u2014 may be the fullest measure of our courage, the great barometer of being fully alive. <\/p>\n

Complement with the blind resistance hero Jacques Lusseyran\u2019s luminous meditation on seeing the heart of life<\/a> and The Vampire Problem<\/a> \u2014 another brilliant and haunting thought experiment, illuminating the psychological paradox of transformative experiences \u2014 then revisit Oliver Sacks himself on the necessity of our illusions<\/a>, the building blocks of personhood<\/a>, the three essential elements of creativity<\/a>, and the measure of a life fully lived<\/a>.<\/p>\n<\/p><\/div>\n
