The Set Theory of Human Connectionby Andrei Bontaș

Set theory begins with the simplest idea: collect things together and call that collection a “set”. At first, that seems innocent enough, but here’s the complication: a set isn’t defined by what it means, but by what it holds inside. That’s its beauty, and also its cruelty. 

Take two strangers on the internet. They are already two sets themselves, or perhaps just two members of the larger set we might call “Strangers”. But does belonging to that set mean anything at all? Or does meaning emerge once we redefine ourselves as members of the set “Lovers”? If so, then maybe not all sets are equal: some carry nothing but bare membership (Strangers), while others hold the weight of a story (Lovers). 

Perhaps that’s where the real tension lies, between membership and meaning. In set theory, the ordered pair “(me, him)” is no different in structure than “(apple, orange)” or “(2, 3)”. Yet, when it happened to me and him, it wasn’t abstract; it was significant. Set theory doesn’t care why two elements pair. It only cares that the pair exists. However, humans can’t help asking: why this pairing, and what does it mean?  

After all, a set itself is always defined by us. The moment we choose what goes in, meaning sneaks in through the back door. We decide the rule, decide what counts, and suddenly the clarity becomes muddy. Machines can apply set theory without hesitation, but can we, as humans, ever use it without dragging in our very humanity?

Consider the pair “(apple, orange)”. Formally speaking, I could place it inside the set “Lovers” and nothing in the math would break. Membership satisfied, relation defined. But then what? Do we imagine the apple and the orange holding hands? Of course not, that’s absurd – so is the meaning bare? 

Now compare it with “(me, him)”. Place that pair in the same set, and everything changes. The pair doesn’t just exist; it demands meaning. Apples and oranges don’t stay up until three a.m. confessing fears. They don’t trade sweaters that still smell of each other. The math treats both pairs the same, but only one of them becomes a story.

Moreover, there’s the matter of membership changing. Two people start as members of the set “Strangers,” then briefly redefine themselves as members of “Lovers”, only to be reassigned, later, to “Strangers”. In logic, nothing extraordinary occurs. It’s just reclassification. For us, though, the shift was anything but neutral. It carried joy, vulnerability, regret. Hence, the mathematics is consistent, but the lived experience resists such indifference.

If that does not convince you, let’s turn to the most haunting puzzle: the empty set, ∅. In set theory, ∅ is simple, a set with no elements (a box with nothing in it). However, in life, to become ∅ feels like annihilation. When he blocked me after my apologies, or when old gifts were returned in three seconds at the station, our intersection was formally reduced to ∅. Nothing remained that could be pointed to. Yet, inside me, the empty set was never empty. It throbbed with memories, with residues that refused to vanish. Set theory insists ∅ holds nothing, but heartbreak insists otherwise: absence itself becomes its own element, and that fills the set to the brim.

At times, I began to feel like a criminal inside that formal landscape. Not before a court of law, but before the tribunal of membership. The accusation was neat: “You pressured me, you demanded, you turned a preference into an ultimatum”. In set theory, those wrongs are discrete elements in the set “Errors”. But is being judged based on those elements the same as the truth? To be reduced to a finite list felt unbearable: my whole set collapsed into the single element “Guilty”.

Indeed, it is strange to be treated as if membership in someone else’s set could nullify your own. In natural language, he returned sweaters and gifts, then blocked me. Formally, Me ∩ Him = ∅. Practically, the world rearranged itself to exclude me. The public story assembled afterwards: partitioned among friends, curated in confidences, placed me firmly on one side of the story, and him on the other. 

The arithmetic of blame seemed inescapable, so I rehearsed confessions, drafting apologies as if they were proofs: initial premise (I pressured), later premise (I see why this hurt), conclusion (I am trying to change). But a proof only persuades if both accept its axioms. He did not. His choice was to sever the relation, to treat the mapping as invalid. My careful logic felt childish beside the blunt mechanics of withdrawal.

At the end of the day, though, here is the counterexample: being reduced to one element is not the same as being nothing. A set can be partitioned, its intersection emptied, but its original membership leaves a trace. The sweater he took back is gone from my hands, but the warmth remains in memory. The apology remains too; it does not need acceptance to exist.

∅ is absolute only within its own frame. Outside his choice, I am not ∅. I remain a subset of larger, kinder sets, friends, family, words, futures. I was not erased. At worst, I was redistributed, reassigned into the broader mathematics of connection. Even the empty set, in my heart, is never empty; it hums with memory, with the stubborn proof that love once intersected me. If that can be true, then so can its opposite: that new intersections will come, unannounced. When they do, the mathematics will change again. Hope, perhaps, is nothing more than trusting that the set of connections is

infinite, and we are always inside it.
