I have previously established that the experience of the 5 senses and their counterparts*, which does indeed define the whole scope of subjectivity, originates independently from the external world; color, for example, is not a quality of an object, but a entity separate from what we usually deem the material world. Now I would like to explore the implications of this conclusion regarding the interaction between the observer and observed.
Depth, a characteristic of sight, requires that there be color. A three dimensional object could not exist without some filler - be it white or red or black or even a pitch, as previously suggested - to give it subsistence, and thus one, with the normal set of experiences to draw from, could never imagine a sphere without color. The perception of color, however, does not necessitate depth; it can take a secondary form by coming to the viewer in a flash of light, a single color not organized into a matrix by the brain, like a single note hitting the ear.
So if we are to accept that the qualities of perception have no root in the actual substances, then depth, which those qualities form, has no foundation. I find this incredibly interesting. What does an atom look like? When one hears the name, the memory of some middle school pictures pops up, maybe a group of balls with some electrons buzzing around it, or, in more learned minds, a fuzzy electron cloud. Yet these impressions come from conceptualizations. As it has no color but that sometimes created by a run-away photon, one cannot see the atom. Despite the volume and mass, there is no way of describing its stuff except mathematically.
Although its origin may be uncertain, some kind of process accounts for the changes we perceive, governed by definite rules. To reconcile this fact with the apparent lack of depth, I propose this hypothesis. The process really may not have any spatial existence, and the depth that we feel, in this case, is merely an additive quality of our experience of the process. In this view, external reality is merely an abstraction, a interaction of probabilities or calculations, feeding subjectivity information. The two are inseparable, one providing the stuff, the other shaping.
*I will try to categorize experience in a following post.
