Knowledge Particles
Sometimes we mean by “knowledge” the whole, the totality of all known data, models, theories, laws, and so on. At other times, however, speaking of “knowledge” refers to single elements, even tiny little facts, measured values, the length of a rod, for example.
In analogy to physical concepts we may talk here of bodies of knowledge in the space of knowledge.
The abstract physical space can be defined by generalizing the concept of extent, a characteristic feature of the concretely perceptible physical objects. But the objects of knowledge? Do they also have kind of length or anything comparable, being abstractable to some corresponding space?
Well, whatever that may be, normaly we do not seem to really need it. Facts, at least, should better be exact, measured values should be as precise as possible, truth must not be possibly wrong. Such kinds of extents would be rather distracting.
Which, by the way, generally applies to physical objects, too. In mechanics, for instance, we are used to ignore any potential or real extents, treating the bodies as mere point masses. Their motions are transitions between distinct occurances at definite points in space.
So, seen in the light of physical science, the physical objects actually are objects of knowledge. They do not verifiably exist but in their observable, especially measurable, appearances. These are the facts. The rest is interpretation. Of course, we know that they exist in between. Experience proves it. But all that definitely counts are the facts, the data, the knowledge particles.
On the other hand, however, it is just the in-between that matters. The pure facts are poor facts, actually no facts at all. Standing isolated for themselves they do not make any sense. They must form a body. This body never comes from the facts alone. It is knowledge. Widespread though widely unprovable knowledge. This is the real substance of every body. It makes its volume, it is spatial, extended.
So after all every thing is extended, even the seemingly most infinitesimal tiny little fact. Because it is knowledge.
