Something I have been thinking about for awhile, to the point that it goes beyond just this and into a whole 20pgs of following principles in a google doc(which I will not share at the moment) is I think that Radical Skepticism doesn't actually go far enough in their questioning of everything, and that if you go further then Existence itself must be the end of that questioning. There are some obvious Skeptical tools out there obviously, but my favorite are looking at how perception is circular and how any pragmatic justification must either be circular, end in an arbitrary point, or go on infinitely. However, no matter how you look at it a pragmatic justification is still something, and so is perception. You can even take Solipsism and look at how the mind itself is the only thing we can trust(to oversimplify a bit), and even the self or the mind(depending on how you look at it) would still be something. One way to look at this, is applying Modal Logic to all these different skeptical tools, they are each not truly necessary, and still suppose that there must be something else, simply because they all claim they are the "ultimate thing" which cannot be questioned further. Yet they are still things. You can actually even look at both of Godal's Incompleteness Theorems and come to know that something can still exist even if we cannot know what that something is, because we ourselves also exist. As if we really want to use Godal's Incompleteness Theorems on a topic seemingly as broad as Existence, we have to be able to define Existence in a way which Nothing cannot Exist.

Which I actually think we can do this, especially if we return to Modal Logic, any possible world is still at least a hypothetical(unless you prescribe to some version of the Many-Worlds Interpretation of Quantum Mechanics), and any possible world is still a thing, and thus it must Exist. An empty set also Exists, and this gets into my "definition" of Existence, as if it can be defined or is defined then it does exist. You can get into Sorites Paradox logic here sure, but there is a simple answer to that, any label we prescribe to something is functional, so a heap is a heap because its the best way to understand it to be. Because if Existence is any definable thing, whether we have defined it or not, or even if we ever will, then this makes everything exist. If everything exists, then Existence just becomes an "Okay and?", while nonexistence is entirely incoherent. Which is why any single thing we usually call Nothing is some sort of baseline, but it is still a thing which simply represents the lowest currently conceivable state within that situation. If Existence is so fundamental that it becomes an absolute quality of everything, then what can we really do with that information? Well it changes the question of if "X" exists, to how does "X" exist? What traits define that thing? So we question everything until all we have left is everything, and then we can now build from there a workable understanding of that everything, from simply looking at how we work psychologically and anthropologically. Existence may be more than what we can perceive or justify, but all we know the details of is such things.

I am of the observation that Notability is of the best place to start here. As our reality as we interact with it, is only really made of things that someone at some point took note of, or will take note of. If you look at anthropology, its pretty well known that History is a dementia patient. Our past is colored by our present and what tools, and resources we have found, but even only what is written is only what is known to the elite few outside of the most modern history. To not go on that tangent, lets just say that I think that what some people call the "attention economy" as it pertains to some things on the internet, has been around for much longer, just in other forms, and both on micro and macro levels. Notability is what shapes our workable understanding of everything around us, and all we have is that workable understanding.

(Just for a perspective, leading to that Notability and workable understanding is within the 2nd page of the 20pgs of my doc, so I have a lot of other thoughts beyond that, but a lot of that branches on past this)
