The value in articulating the subtlest nuance of an emotion, or occurrence, lies in giving the appreciator the pleasure of knowing that they are not alone, the knowledge that you also felt, and were aware of, and cared enough to articulate, and document, that nuance.
There is, of course, also the charm of being able to demonstrate your ability, i.e., that it’s impressive to the viewer to see that you were able to catch and articulate that detail. No small feat! But aside from the impressiveness factor, there is also the companionship factor.
And then there is also the collector/archivist element, where you want to have as a great a collection as possible – like the ideal insect or beetle collection – ‘ideal’ usually being defined as having as many different specimen as possible, however slightly or minutely they may differ, without having two of exactly the same.
This also explains the length of Rubber Tricks, which attempts to capture as much of the human experience as possible, including the slightest variations and subtleties, without ever saying the exact same thing twice – every nuance, with no repetition. Also not too unlike mathematical formulas which try to say as much as possible with as little as possible, i.e., with as few formulas as possible and with the simplest formulas possible, with the ultimate goal of one day finding a relatively simple formula that explains everything that we can conceive: The Theory of Everything.
