What makes us who we are? Is it memory—the names, dates, and stories we carry? Or is it something more elemental, more enduring?
This question has followed me for years—from lab bench to bedside, from daughter to doctor. But it wasn’t until I watched the people I love lose their memories that I began to see something unexpected: When memory fades, something essential still remains. Love. Imagination. Presence. These aren’t just what’s left behind. They may be the very ground of who we are.
When Memory Loops and Language Fails
I remember my grandmother’s sharp intellect slowly dimming under the weight of dementia. Her questions looped. Her gaze, once bright with recognition, turned vacant. Later, during medical training, I stood beside a woman with early-onset Alzheimer’s as she asked the same question three times in one breath. These weren’t just clinical observations. They were heartbreaks.
Then came my mother’s diagnosis. ALS—an unforgiving disease that silences the body before the mind. I watched her lose the muscles that carried her voice, her breath, her smile. But even as her body failed, something unshakable endured. Her imagination. Her presence. Her love. She could no longer speak, yet her gaze held warmth. Her eyes still sparked with mischief. I began to ask: Could imagination be the heartbeat of consciousness?
Science Meets Mystery
I spent decades immersed in biochemistry, molecular biophysics, and medicine, searching for how the self holds together. But grief made that inquiry personal.
I remember staring through a microscope at newly discovered human embryonic stem cells. They glowed like constellations—formless, yet radiant with potential. Inside them were the instructions for a body, a brain, a beating heart—and maybe, I thought, the flicker of consciousness. It felt like watching the universe write its first sentence.
A Detour Into Psychedelics—and Deeper Knowing
When the pandemic quieted the world, that old question returned. In the stillness, I read How to Change Your Mind, and something dormant cracked open. I turned to psychedelics, not as an escape, but as a lens into consciousness itself. What happens when we step outside ordinary awareness? What emerges when the known dissolves?
In those altered states, I encountered a kind of knowing not bound by memory. I wasn’t recalling, I was recognizing. Insights long held apart clicked together. It made me wonder: Is memory just one expression of something deeper? Could love and imagination be the structure beneath awareness?
Recent research shows that during psychedelic states, ego boundaries may dissolve while a powerful sense of connectedness remains, suggesting that selfhood may be relational, not just autobiographical.
Rethinking the Thread of Selfhood
We often treat memory like a filing cabinet. But what if it’s more like a thread, one that connects us not only to the past, but to each other? And when that thread begins to fray, perhaps it’s imagination—our capacity to picture, to create, to feel—that holds us together.
Studies of the brain’s default mode network—linked to memory, self-reflection, and imaginative thinking—highlight the role of creativity in maintaining identity and meaning. A 2021 trial in Scientific Reports found that a single dose of psilocybin enhanced both convergent and divergent thinking. After a guided session, I experienced this firsthand: Problems that once felt disjointed began to integrate. It wasn’t invention. It was recognition.
Forgetfulness exists on a spectrum—from misplaced names to a vanished sense of self. Yet new research suggests that emotional memory and social responsiveness often persist in dementia, even when verbal communication disappears. Some theories propose that the self may not be stored, but patterned—woven from perception, embodiment, and relationship.
The Final Threshold: Being Felt
We can track brain waves, map what fires and what fades, but we still don’t know what consciousness is, or where it lives. Science can outline awareness. But it cannot yet touch its essence.
Still, I believe this: Even when we can’t see the glimmer of what once was, what remains may be the most essential. A glance. A smile. A whisper of presence. Love.
We may be called to see differently. To trust that worth has never rested on cognition alone. That dignity isn’t earned through memory, but revealed through connection. Even when the lights dim, something endures—not always visible, not always nameable, but still felt. In the nervous system of a glance. In the heart that keeps showing up. In the web of care that holds us in place.
But what happens when even that connection is lost, when no one meets the gaze, no one remembers the name, and the thread of presence snaps?
Is It gone?
For the person, it may feel like vanishing. Not the absence of memory, but the absence of being felt. Without relational mirroring—without someone holding their dignity in place—the self risks dissolving not just neurologically, but existentially. A life still present may be mistaken for one already gone.
So if you find yourself with a loved one who no longer remembers your name, don’t ask, What have we lost? Ask, what can we still feel together?
Even in the absence of recognition, connection can still be made. Through tone. Through touch. Through the quiet insistence of showing up.
I don’t just believe this. I’ve lived it.
And in that knowing, there is awe.
