So many people accept at face value either some identity given to them by others or perhaps the assumed identity developed by a younger self. They stop looking or maybe they've never looked much at all. This is what's so dangerous about the materialist misconception that *there is no soul!* What do you mean by that? Do you even know? To the person who needs soul-searching, if they believe the soul resides entirely within some internalized encoding of matter, then they allow the noise of life to define all they see and all they think. They believe the extent of their soul to exist entirely separately of society and this is a dangerous assumption because it deprives the person of power over their mind, over their life and over the composition of their soul.
This categorical coherence looks for higher level patterns. It could identify the presence of diseases previously unknown, not because it's matching against a list of diseases and their progressions, but because it's identified unknown patterns of neurodegeneration in a patient. In addition to unknown disease progression, this could also identify the combination of drug-induced neurological damage or damage induced by the combination of diseases.
While certain physical neural circuit arrangements are required and while chemistry and genetics are certainly involved to some degree, I believe this merely sets up circuitry that will evolve to reflect metaphysics -- *heady crystals!!* -- In other words, given the proper initial circuitry and given a variety of similar input experiences, the remarkably small spider's brain will inevitably evolve certain key functionalities -- or it will not survive.
