Life doesn’t care much for your rules. My nephew, all 7 years of him, hit me with this curveball last week: “Uncle, is a car toy inside a backpack one thing or two?”
His teacher, some brave soul, had tossed that grenade into a math lesson.
He picked up a book (one) and a backpack (another one) and said, “Now we have two things, right?” Then he shoved the book inside the backpack and asked, “Now is it one or two?”
The room was silent.
And here I am, middle-aged, hunched over coffee-stained philosophy books, realizing I’m no better than those kids.
I don’t have an answer either.
Backpack Logic: When Counting Fails
This isn’t just about numbers. It’s about mereology—the study of parts and wholes.
It asks the kind of questions that ruin dinner parties.
Are a book and backpack separate because they can exist independently, or does the backpack engulf the book, making them one object?
If that sounds abstract, it’s not. It’s too real. Life’s full of these moments.
When does a relationship stop being two people and become one suffocating mess?
Here’s a handy breakdown for the philosophers and the drunks:
Scenario | Number of Things |
---|---|
Pen next to backpack | Two |
Pen inside backpack | One, or still two—depending on who you ask. |
Backpack falls apart | Infinite: straps, zippers, bits of fabric. |
Hell, even the table I’m typing on is made of parts—legs, screws, splinters waiting for my elbow.
One table or hundreds of pieces? Who decides?

Explaining It to the Kid
“Listen,” I told my nephew. “Imagine you’ve got a LEGO car. You put it together. Now it’s one car. But if I pull it apart, it’s, what—thirty pieces? Sixty? Who’s counting?
Numbers aren’t magic—they’re just tools. We decide what counts.”
He frowned. “So, if I put a LEGO wheel in my pocket, is it still part of the car?”
“Exactly. And good luck getting an answer. That’s why philosophers drink.”
The Stubborn, the Pragmatic, and the Blissfully Unbothered
Not everyone buys into this book-backpack madness. Some folks like their truths clean and sharp, like a fresh blade.
Mathematicians, for instance, don’t give a damn about your “things.”
To them, 1+1=2 because they said it does. It’s a closed system, airtight, like a coffin.
They don’t care if you’ve got a pencil, a backpack, or a corpse stuffed inside; the equation holds.
Context? Irrelevant. Just like how most of us treat other people’s problems. You might be drowning in existential dread, but they’re already two drinks in, shrugging, “Not my issue.”
Here’s how some of the big thinkers frame it, for better or worse:
Thinker | Argument |
---|---|
Frege | Numbers cling to concepts. A tree is “one tree,” but also “1,000 leaves.” |
Dewey | Math is human-made. It’s not eternal truth—it’s a wrench in the toolbox. |
Everyday Math Nerd | 1+1=2. Always. Forever. Don’t drag me into your philosophical dumpster fire. |
Frege, the calculating type, ties numbers to ideas. One pen, one backpack—but also two objects, or maybe just one whole mess depending on how you slice it.
Math’s an idea stapled to reality, but it wiggles when you try to pin it down.
Dewey? He’s my kind of cynic. Math is just another tool we built, like chairs or alarm clocks. He admits it: logical forms—including math—were born from human inquiry.
We didn’t find math hiding under a rock; we made it because we needed it. It’s no eternal truth. It’s duct tape for the mind—handy but prone to peeling.
And the everyday math nerd? Oh, they don’t have time for this. “1+1=2,” they insist, like a mantra.
End of story.
Don’t talk to them about pens or backpacks or the fact that milk and popcorn combined make less than two cups.
That’s your problem. They’re busy balancing checkbooks and laughing at the rest of us for questioning it.
When Reality Fights Back
But even math, that smug bastion of certainty, folds when the real world leans too hard.
Like anything else we’ve built—math isn’t unbreakable.
Dewey saw it clearly: when things get messy, the tools we trusted don’t always work.
Take 1+1 in the abstract: pure, untouchable. Then drop it into life. A cup of milk plus a cup of popcorn equals…what? 1.25 soggy cups?
The world doesn’t give a damn about your perfect equations. It laughs, it spills, it cracks open, and math—like the rest of us—has to scramble to keep up.
Math might be practical, but it bends, it warps, and when it snaps, you’re left holding a book, a backpack, and no clue how to count them.

Nihilism in a Backpack
And that’s the thing, isn’t it? This isn’t just about pencils. It’s about whether anything means anything.
If 1+1 doesn’t always equal 2, what else can’t we trust? Love? Morality? The comforting lie that things add up in the end?
Bukowski had it right: “Sometimes you climb out of bed in the morning and you think, I’m not going to make it, but you laugh inside—remembering all the times you’ve felt that way.”
So maybe the question isn’t about math at all. It’s about how we decide what matters. Whether we count the pen or the backpack, or just laugh and say screw it, let’s go get lunch.
A Flicker of Hope
Still, there’s something beautiful in the wreckage.
The teacher wasn’t dismantling math; he was showing the kids that it’s ours to define.
The world doesn’t hand us truths wrapped in shiny paper. It gives us backpacks and pens and asks us to make sense of it.
In Slaughterhouse-Five, Vonnegut throws us a bone: “So it goes.”
Simple, right? Some words strung together in a way that says everything and nothing all at once.
Maybe that’s the best answer we’ll ever get. The universe doesn’t give a damn about our need for meaning. It doesn’t owe us clarity.
It’s indifferent, like the guy at the bar who listens to your whole tragic story then says, “Well, that sucks,” and goes back to his drink. That’s the universe for you.
But here’s the mad part—we still try. We dig through the mess of life, the random chaos of it all.
We claw at it with bloody hands, convinced there’s some hidden pattern underneath, some grand meaning buried beneath the madness.
We find fragments, symbols, signs. We string them together, convince ourselves they matter. We call it meaning. We wrap it in words, dress it up in metaphors, and hope it sticks.
But at the end of the day, it’s all just “So it goes.”
Meaning is a joke, and we’re the laugh track.
But hey, maybe that’s all there is. We laugh, we cry, we keep digging, even though we know that nothing we find will ever be enough.
The universe doesn’t owe us a damn thing.
But we search anyway, because what else is there to do?
So here we are. A pencil, a backpack, and a question. Do we let the absurdity paralyze us? Or do we keep moving, keep counting, keep finding ways to make 1+1 something worth believing in?
The future, like everything else, depends on what we choose to see.
