Asian parents love to compare the heights of kids and adults alike by laying their hands flat across the tops of their heads. I am Asian, and want to be a parent. (My wife and I are trying.)
Read this as a wish fulfillment story; or as a roundabout description of the emergence of truth and lies from abstraction, fiction becoming fact, epistemology and ontology lying to you or others; or as a religious proof text of the futility of human knowledge.
Difference
In most cases, two objects cannot be "literally" the same length if we look to the smallest measurable units of the current age. What is the likelihood that if we zoom in enough, two men who (credibly) claim to be six feet tall are exactly the same height? There is certainly (overwhelmingly likely) a difference.
Meaning
But imagine if a person laid their hand across the heads of these two men, and felt that their hand was perfectly flat. This could very well be illusory or imagined, but the perception is exactly so. Could I tell, were I this person? (From now on, I am this person.) Any difference ceases to have meaning in this context.
Sameness
We decide to speak of their heights as the same. One height is not distinguished from the other. Every axis within this narrow scope is redundant. The sameness is so self-evident that no one within the specific frame is as to reject this truth.
Equality
We may treat then redundant objects within a context as being equal. They are used interchangeably, such that if I were to measure a third person's height, I could use either of the first two men as a large measuring stick. From there, I could see if the third man is shorter or taller. Or, if my hand is as flat as it was for the first two men, I would once again claim equality.
Precision
Of course, we knew that there was a difference. Just not a meaningful one. But suppose we found a way to heighten the sensitivity of the hand such that it could perceive more minute differences in height. Or, more directly and pertinently, it can perceive smaller deviations from perfect flatness. Maybe the hand was always biased in one direction. Maybe there was a systemic way in which a slightly taller person was more likely to stand on one side. If I could account for more, then I would be even better at perceiving difference. This increases the precision of my statement that two people are the same height.
Standard
Three people's heights are re-measured, and even after practicing some good old rationalist epistemic hygiene, the three people are the same height. Imagine if I did this a million more times, using any person I consider to be the same height of around six feet (plus or minus some unknown value) to measure new people who could possibly be their height. I might notice that by using multiple people to measure the same person, I can get a good grasp of if a group of people really are the same height. I am generating a standard for a particular height around six feet tall.
Error
Eventually, the number of people I have pegged at the same height grows to an amount where I might have failed to measure every combination of people with my hand. The standard has petered out in its effectiveness since there are now more specimen for the standard than I could reasonably use. Eventually, if GOD (the GOD of Difference) ordered all the people of "the same height" from shortest to tallest, I might take the shortest and the tallest and find upon laying my hand that—tell me it ain't so!—there a difference, a meaningful difference, a lack of sameness. Yet there was always that supposed equality all the way through. What happened? There is error in the standard.
Margin
Luckily, whatever difference I feel right now, I know that this is the worst it could really get. I take these two people from the ends of the line created by GOD, and also take another person from exactly in the middle. Upon laying my hand flat between this median person and either of the endpoint people, I feel there is no difference from short to middle or from middle to tall. Even though I know there is certainly a difference, a meaningful difference, between the two endpoints, it still feels convincing enough that the shortest man is the same height as the median man, and the median man is the same height as the tallest man. Same is same is same. I continue using my standard, accepting that there is a margin of error.
Game (or, Copula)
I trim the endpoints til I again cannot tell the difference between the shortest and the tallest, then a little more til the roster is a little more manageable. I keep on using the new endpoints and the median to see if men are exactly the same height as the men in my pool. My standard is trusted, and I rent-seek from being a paid expert on this standard of some arbitrary height some distance above or below six feet. I live happily ever after, til I start abusing this margin of error to game the standard. How do I game the standard? I leave this as an exercise for the reader.
