There’s a thought experiment often known as Mary’s Room, good and haunting, in regards to the abyss between felt expertise and our psychological fashions of it, in regards to the nature of data, the thriller of consciousness, and the irreducibility of aliveness: Residing in a black-and-white chamber, Mary the scientist research how nature works — from the physics of sunshine to the biology of the attention — however when she exits her monochrome room and encounters shade, she experiences one thing far past her information of what shade is. It could be unattainable, the experiment intimates, to think about — even with our best information and greatest predictive fashions — what an expertise would really feel like earlier than we now have it, uncooked and revelatory and resinous with the one factor we are able to by no means mannequin, by no means cut back to data: surprise — the surprise of the world all of a sudden new and we all of a sudden new to ourselves.
Neurobiologist Susan R. Barry was in her fifties when she realized she had been dwelling in Mary’s Room.
Born cross-eyed and stereoblind — unable to type three-dimensional photos the way in which most individuals do as we intention our two eyes in the identical course, combining the visible enter within the mind — Barry had undergone a variety of corrective eye-muscle surgical procedures as a toddler, which made her eyes seem aligned. She was instructed she was cured, capable of do something individuals with regular imaginative and prescient do besides fly an airplane.

It was not till her junior yr of faculty that, listening to a lecture in regards to the visible cortex and ocular dominance columns, she discovered about monocular and binocular imaginative and prescient. She was astonished to comprehend that she had gone by life missing the latter — the sort most individuals have, which permits us to see in stereo. She accepted her situation and went on dwelling with the lens probability had dealt her. However by midlife, her eyes had grown much more misaligned, each horizontally and vertically. She discovered a few form of imaginative and prescient remedy involving a set of prism glasses and a few impressively creative eye-training workouts. It was transformative. Work started to look extra three-dimensional and she or he may see “the empty, but palpable, volumes of area between leaves on tree.” She recounts:
Over the subsequent a number of months, my imaginative and prescient was fully reworked. I had no thought what I had been lacking. Abnormal issues seemed extraordinary. Lighting fixtures floated and water taps caught method out into area.
Three years into relearning to see, she met Oliver Sacks at her astronaut husband’s area shuttle launch. Together with his passionate curiosity in regards to the interaction of physiology and psychological actuality, the famed neurologist requested her a query that got here to hang-out her: Might she think about what the world would seem like seen with two eyes?
As a neurobiology professor herself, having written and browse numerous papers on visible processing, binocular imaginative and prescient, and stereopsis, Barry was at first sure she may. However the extra she thought in regards to the query, the extra she felt into it, the extra she realized that one thing important was lacking from her cerebral understanding: She was Mary, and the world was the world.

Discomposed by the implications of the query, she determined to achieve out to the questioner — for orientation, for comfort, for collaborative reckoning with this all of a sudden uncovered side of the confusion of consciousness. “That’s my story,” she wrote on the finish of the nine-page letter detailing her uncommon imaginative and prescient historical past. “When you have the time and inclination, I might vastly respect your ideas. And, in fact, I eagerly await your subsequent e-book.”
Inside days, Oliver had written again. Amazed at her defiance of the chances — it had lengthy been accepted that binocular imaginative and prescient should be achieved by a “important age” or will without end elude the seer — he expressed his admiration for her willingness to welcome her “new world” with such “openness and surprise.” So started their decade-long correspondence, which helped Barry “form a brand new id.” This richly nourishing epistolary friendship, which lasted till his demise, now lives on in her great part-memoir, part-memorial Expensive Oliver (public library).
From her very first letter, she units out to convey the wonder-filled disorientation of her newly skilled imaginative and prescient — a metamorphosis each life-expanding and overwhelming, given the coevolution of imaginative and prescient and consciousness. She writes:
Think about an individual who noticed solely in shades of grey all of a sudden capable of see in full shade. Such an individual would most likely be overwhelmed by the great thing about the world. Might they cease trying? Every day, I spend time trying head-on at objects — flowers, my fingers, taps, something — with the intention to get that robust three-dimensional sense… After nearly three years, my new imaginative and prescient continues to shock and delight me. One winter day, I used to be racing from the classroom to the deli for a fast lunch. After taking only some steps from the classroom constructing, I ended quick. The snow was falling lazily round me in giant, moist flakes. I may see the area between every flake, and all of the flakes collectively produced a lovely three-dimensional dance. Up to now, the snow would have appeared to fall in a flat sheet in a single aircraft barely in entrance of me. I might have felt like I used to be trying in on the snowfall. However, now, I felt myself throughout the snowfall, among the many snowflakes. Lunch forgotten, I watched the blizzard for a number of minutes, and, as I watched, I used to be overcome with a deep sense of pleasure. A snowfall might be fairly stunning — particularly if you see it for the primary time.
Barry’s query about whether or not one could possibly be so overwhelmed by a brand new method of seeing as to cease trying will not be rhetorical — the historical past of medication is strewn with instances of blind individuals receiving corrective surgical procedure that grants them sight, solely to reject the brand new actuality of sunshine and return to the acquainted world of darkness, shifting by their lives with eyes shut.
These physiological transformations are a haunting analogue for our psychological pitfalls — accepting change, even towards one thing that deepens and broadens our expertise of aliveness, is rarely simple, partially as a result of we’re so poor at picturing an alternate rendering of actuality. “The issues we wish are transformative,” Rebecca Solnit wrote in her very good Discipline Information to Getting Misplaced, “and we don’t know or solely assume we all know what’s on the opposite aspect of that transformation.” We stay so typically misplaced in our frames of reference, lulled by the acquainted, too terrified to stay a bigger life on the opposite aspect of a metamorphosis that upends our snug methods of seeing and of being. (And what’s the self if not only a fashion of being?) It takes each nice braveness and nice vulnerability to welcome such a change — a metamorphosis typically mired in uncertainty, discomfiture, and confusion as we adapt to the overwhelm of life extra magnified; a metamorphosis that asks us to start once more, and a starting all the time locations a singular pressure on the psyche.

Years into their correspondence, Barry shares with Oliver the case of a younger girl who embodied this brave willingness to welcome transformation — a scholar of hers born with nearly no listening to, who had obtained a cochlear implant at age 12. Barry writes:
When her implant was first turned on, she didn’t acknowledge a sound as a sound however fairly as a terrifying, disagreeable, unnerving feeling. For the primary few days, she had this identical scary sensation each time she placed on the implant. Finally, she mentioned, she got here to just accept the sensation. Then she started to anticipate the sensations and to interpret a few of them as significant sounds.
[…]
I used to be intrigued by her use of the phrase “settle for,” as a result of I feel anybody who goes by a considerable perceptual enchancment should study to tolerate a certain quantity of discomfort, uncertainty, and confusion. If one doesn’t have the help of docs, therapists, household, and/or pals, then one could not permit the adjustments to happen.
The diploma to which we permit transformation — whether or not it comes within the type of new prism glasses or a brand new cochlear implant or a brand new love — would be the fullest measure of our braveness, the good barometer of being absolutely alive.
Complement with the blind resistance hero Jacques Lusseyran’s luminous meditation on seeing the guts of life and The Vampire Downside — one other good and haunting thought experiment, illuminating the psychological paradox of transformative experiences — then revisit Oliver Sacks himself on the need of our illusions, the constructing blocks of personhood, the three important parts of creativity, and the measure of a life absolutely lived.
