To cognize any is to cognize all.
Due to the intricately interrelated nature of all events and phenomena, in order to truly know any fact, all contingencies of such fact must also be known. Otherwise, by definition, such fact is not completely "known" per se. I may know the sky is blue, but this knowledge is contingent on the time of day and weather, among other things. I may know that my normal hand has five fingers on it, and most people would agree with this, thus establishing fact by consensus. However, there would be some who might point out that there are, in fact, four fingers and a thumb on a normal hand. Still others might count in binary, insisting that there are one-hundred-and-one digits on a normal hand, one-hundred of which are fingers. This premise is implausible, if not wholly impossible, to argue against in any reasonable context. Every generation produces a crop of those who really think they have everything all figured out in spite of how many times this has occurred previously. History is a list replete with examples of rational and logical errors supplanted (hopefully) by less error in thought and its reflection. Perhaps the classic example of chronically obsolete “knowledge” is that found throughout astronomy’s history. Reflecting on and extrapolating from this history, our safest bet would be that the study of astronomy is not yet complete and wholly accurate. Due to this constraint on our knowledge, we have no reference against which to even gauge any absolute progress in astronomy. Astronomy is an example of what happens to human knowledge as it becomes more mature under power law distribution. As we seem to progress, we believe we know more, but only in relation to what we “knew” before. We never know how much we know in relation to how much we can know at some point in the future. This is true not only for astronomy, but also for any other subject of science, art, literature, education, government and any other institution which deals in human knowledge. Given the glaring fact of there not being any perfect textbook, yet anyway, it is entirely probable that, in fact, we really "know" nothing at all, consciously. Subconsciously, we may be universally aware of everything in the same manner as everything is universally aware and intercommunicating amid the phenomenal milieu of fact being connected by electromagnetic radiation and the forces of nature. Awash in data and information, subconsciously we could know everything, but this could stand in sharp contrast to how little we know consciously. If our college textbooks are any indication of what we "know", because there are no perfect textbooks, i.e. textbooks without any need for revision, we have no certain or conclusive conscious knowledge of anything. This reveals telling inferiority inherent in conscious fact, which is always information, or poor fact. Pure fact, or data, is superior fact, but we are aware of such pure fact only in that realm of the mind which is inclusive, i.e. the subconscious, subliminal mind as opposed to the exclusive domain of the conscious mind. The exclusive conscious mind is primarily concerned with focus of thought, keeping one idea upon which concentration remains centered at the exclusion, sometimes overt ignorance, of all other thought. So, while the conscious mind primarily excludes other, interfering thought, the subconscious mind is incapable of such mental filtration, and, as a possibly astounding result, it is entirely plausible that we do subliminally really know everything. Data are everywhere, and all things are connected to all other things in a milieu of phenomena and epiphenomena saturated with pure fact. It only transforms into information through the attenuation of conscious thought. As a result, we become prisoners of fact rather than its masters. (While fact theory implicitly predicts its own error, it should be amusing if that prediction is its only significant error. The best facts are plain, and among the plainest of these is that facts are all interrelated. A relative fact, incompletely known, is merely fractionally known, and not known or cognized totally. This fact alone should honestly temper and humble our judgments about and of each other. The quality of fact varies across a full spectrum all the way from pure fact, or data, through poor fact, or information. Fortunately, it is quite safe to guess that there are nearly infinitely more data available in the universe than there is information. Unfortunately, in current events among humans, we are continually bathed and utterly saturated in the poor facts of mere information, the predominant medium of the conscious mind and mentality.
