The Empty Set: A Mathematical Net That Even Traps ‘Nothingness’
In mathematics, the empty set is a peculiar entity. It contains not a single element, yet it is undeniably granted the status of a “set.” What does this signify? It means that whether an object exists or not, or whether we can define it or not, the moment we place it into a “pouch of perception,” it is incorporated into the mathematical system.
Suppose I model “people who look like Won Bin” or “people who look like Timothée Chalamet,” but the criteria are so rigorous that not a single person on Earth qualifies. Even then, it exists as a “set with no elements.” Ultimately, at the very instant I establish a criterion (a model), a fragment of the world inevitably takes on the character of a set.
Is There Truly Nothing That Is Not a Set?
Is everything in the world, then, a set? Here, I observe the tension between “undefined chaos” and “defined cosmos.” To become a set, the premise of being “well-defined” is required. My act of setting variables and assigning weights through modeling is the work of drawing a “boundary line” upon a disordered reality. If there is something I have yet to model—something raw that human intellect has never once categorized—it might, for a fleeting moment, remain in a “non-set state.”
However, the moment I perceive it and ask, “What is that?”, it begins to enter the aggregate of my thoughts. Ultimately, declaring that there is nothing in this world that is not a set is equivalent to announcing that everything in the world lies within the range of my “perception” and “modeling.”
The Collective Character of All Existence
In the world as I see it, every existence possesses a collective character—whether it is a physical reality, an abstract notion, or even something defined by the attribute of “undefinability.”
- The Reductionist Perspective: We understand the vast system by breaking it down into subsets.
- The Perspective of Generalization: We bind individual elements together to find a single collective law.
In this process, there is no place for that which is not a set. To be “not a set” implies being “incomprehensible” and “unmanageable.” Perhaps the reason I model the world and approach it mathematically is a human instinct that simply cannot endure that “non-set state” (disorder).
Closing: The Fate of the Boundary-Drawer
If even the empty set is a set, then there is no realm I cannot touch. Even if my model is flawed and yields no results, I merely end up possessing one more set named “Failed Model.”
The world, in the end, is an overlapping of countless boundaries (Sets) that I have drawn. Today, as always, I cast the net of my thought into the vast ocean of the world to haul in fish called “sets.” There is nothing that is not a set. There are only hidden elements that I have yet to name, or those whose weights in my modeling converge to zero.
