Radiation, Space, Three-Dimensionality

As previously discussed, on the heliocentric model of Experience, Space originates from Radiation, i. e. from the process of spreading out. Within that fundamental Spatialization, secondary subdividing can occur. The most familiar experiential subdivisions are right-left, front-back, and up-down, each an aspect of basic corporeality. Upon further refinement and abstraction, derivable from those subdivisions are the 'dimensions' width, length, and depth. In other words, on this model, three-dimensionality is a derivative characteristic of Space. So, when Kant asserts that three-dimensionality is an a priori form of Experience, he has strayed from his heliocentric model of it.
