There’s a thought experiment often called Mary’s Room, good and haunting, concerning the abyss between felt expertise and our psychological fashions of it, concerning the nature of information, the thriller of consciousness, and the irreducibility of aliveness: Dwelling 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 coloration, she experiences one thing far past her data of what coloration is. It is perhaps inconceivable, the experiment intimates, to think about — even with our best data and greatest predictive fashions — what an expertise would really feel like earlier than now we 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 abruptly new and we abruptly new to ourselves.
Neurobiologist Susan R. Barry was in her fifties when she realized she had been residing in Mary’s Room.
Born cross-eyed and stereoblind — unable to type three-dimensional photos the best way most individuals do as we purpose 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 baby, which made her eyes seem aligned. She was informed she was cured, in a position to 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 concerning the visible cortex and ocular dominance columns, she realized about monocular and binocular imaginative and prescient. She was astonished to understand that she had gone by way of life missing the latter — the sort most individuals have, which permits us to see in stereo. She accepted her situation and went on residing with the lens probability had dealt her. However by midlife, her eyes had grown much more misaligned, each horizontally and vertically. She realized a few sort 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 he or she 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 concept what I had been lacking. Extraordinary issues seemed extraordinary. Lighting fixtures floated and water taps caught manner 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 concerning the interaction of physiology and psychological actuality, the famed neurologist requested her a query that got here to hang-out her: May she think about what the world would appear like seen with two eyes?
As a neurobiology professor herself, having written and skim numerous papers on visible processing, binocular imaginative and prescient, and stereopsis, Barry was at first sure she may. However the extra she thought concerning 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 abruptly uncovered aspect 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. “If in case you have the time and inclination, I might tremendously recognize your ideas. And, in fact, I eagerly await your subsequent e book.”
Inside days, Oliver had written again. Amazed at her defiance of the percentages — it had lengthy been accepted that binocular imaginative and prescient have to be achieved by a “crucial age” or will endlessly 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 identification.” This richly nourishing epistolary friendship, which lasted till his dying, now lives on in her fantastic part-memoir, part-memorial Pricey Oliver (public library).
From her very first letter, she units out to convey the wonder-filled disorientation of her newly educated 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 abruptly in a position to see in full coloration. Such an individual would most likely be overwhelmed by the great thing about the world. May they cease trying? Every day, I spend time trying head-on at objects — flowers, my fingers, taps, something — with the intention to get that sturdy 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 just a few steps from the classroom constructing, I ended brief. The snow was falling lazily round me in massive, moist flakes. I may see the area between every flake, and all of the flakes collectively produced an exquisite 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 inside the snowfall, among the many snowflakes. Lunch forgotten, I watched the snowstorm 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 while you see it for the primary time.
Barry’s query about whether or not one might be so overwhelmed by a brand new manner of seeing as to cease trying will not be rhetorical — the historical past of medication is strewn with circumstances 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 way of 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 excellent Area Information to Getting Misplaced, “and we don’t know or solely suppose we all know what’s on the opposite facet of that transformation.” We reside so usually misplaced in our frames of reference, lulled by the acquainted, too terrified to reside a bigger life on the opposite facet of a metamorphosis that upends our snug methods of seeing and of being. (And what’s the self if not only a model of being?) It takes each nice braveness and nice vulnerability to welcome such a change — a metamorphosis usually 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 at all times 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 pupil of hers born with nearly no listening to, who had acquired 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 quite as a terrifying, disagreeable, unnerving feeling. For the primary few days, she had this identical scary sensation each time she placed on the implant. Ultimately, she stated, she got here to simply accept the sensation. Then she started to count on 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 way of a considerable perceptual enchancment should study to tolerate a certain quantity of discomfort, uncertainty, and confusion. If one doesn’t have the assist of medical doctors, therapists, household, and/or pals, then one might not permit the modifications 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 nice 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 Drawback — 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 components of creativity, and the measure of a life absolutely lived.
