Do I Exist — When I Was in High School
When I was in high school, there was a night I still remember vividly.
Everyone in the house was asleep, and the only light in my room was a small desk lamp casting a soft glow across my textbooks. I wasn’t studying, though. I was just sitting there, listening to the quiet hum of the night.
That evening, a strange question dropped into my mind—quiet but heavy.
“Do I really exist?”
Not in the “I have homework tomorrow” sense, but in a deeper, almost dizzying way.
I remember staring at my own hands, feeling the weight of my thoughts, wondering how I could be me when everything inside me felt so hard to grasp.
That night was the first time I realized that existence isn’t something we automatically understand.
Sometimes, it softly taps on our shoulder; other times, it hits us like a wave.
And that whisper—“Who am I, really?”—followed me for years, eventually leading me to philosophy, psychology, and the study of the self.
This essay is my attempt to revisit that question with everything I’ve learned since then,
and to offer a calm, grounded explanation for anyone who has ever felt the same quiet confusion.
1. Why Asking “Do I Exist?” Matters
Most animals show intelligence and emotion, but only humans ask about their own existence.
It’s a built-in feature of our consciousness—a sign that we’re aware not only of the world but of our presence in it.
René Descartes said:
“I think, therefore I am.”
But modern psychology suggests something more layered:
we exist not only because we think, but because we feel, remember, choose, and connect.
Asking this question doesn’t mean something is wrong—
it means your mind is awake.
2. Philosophical Views on Existence
1) Descartes — Thinking as Proof of Being
For Descartes, thought itself is the core of existence.
If you can doubt, question, or observe your own mind, you must exist as the observer.
But…
our thoughts can deceive us.
So is thinking alone enough? Philosophers still argue about it.
2) Heidegger — “Being” Exists in Connection
Heidegger believed we exist through relationships:
- with the world
- with time
- with people
- with our choices
In this view, I am not an isolated object.
I’m a being shaped by every context I live in.
3) Eastern Philosophy — The Changing Self
Buddhism and Confucian traditions see “self” as a process, not a solid thing.
We are constantly shifting combinations of:
- emotions
- habits
- memories
- relationships
Buddhism even says:
“There is no permanent self.”
It isn’t nihilism—
it’s a reminder that what we cling to as “me” is always changing.
3. Psychology’s Answer: Identity
Modern psychology defines “self” as an ongoing construction made from:
- memory patterns
- emotional reactions
- social roles
- personal values
- relationships
Psychologist William James divided self into:
- I (the active self): the one who thinks
- Me (the reflective self): the one who is remembered and evaluated
Together, they form the feeling of “I exist.”
Real Example — When Identity Collapses
A common therapy case:
Someone loses a job they’ve had for years.
They don’t just lose income—
they lose a sense of who they are.
They ask things like:
- “If I’m not useful, am I still me?”
- “Where does my worth come from?”
- “What is left of me when roles disappear?”
Existence questions often arise when life breaks our old identity structure.
It’s not weakness.
It’s a normal psychological recalibration.
4. Neuroscience: The Brain Builds “You” Every Second
Neuroscience sees the self not as a permanent entity but as a dynamic integration system.
Your brain constantly merges:
- sensory data
- emotional states
- memories
- predictions
- beliefs
and turns them into a single stream called “you.”
It’s like a movie your brain is producing in real time.
Split-Brain Experiments — Two Selves in One Body?
Patients with severed hemispheres sometimes behave as if they have:
- two preferences
- two wills
- two centers of awareness
One hand buttons a shirt, the other unbuttons it.
One hemisphere laughs while the other denies understanding why.
This shows that the self is not a single physical spot—
it’s a coordinated illusion created by connection.
5. When Do We Feel Most Alive?
Studies show people feel their strongest sense of existence when:
- walking alone and suddenly reflecting
- talking deeply with someone who truly listens
- making a difficult decision
- realizing they influenced someone
- going through a life change (breakup, loss, success)
Existence is not a thing we “have.”
It’s a moment-to-moment experience that becomes vivid through meaning.
6. So… Do You Exist?
Here’s the closest answer modern science and philosophy can offer:
Yes, you exist — not as a fixed object, but as a fluid, ongoing process shaped by thought, memory, emotion, and connection.
You are not a single solid “self.”
You are a story being rewritten every day.
A changing stream.
A consciousness building and rebuilding itself.
And that’s what makes existence meaningful.
