I've decided to develop the footnote from the article ' ' into an entry on the erroneously named Autism (from here on it will be called Acute Single Mindedness, or ASM), and is a mental condition that exists on a gradational scale starting from zero, which would be non existence.
Those who have the condition do not consider themselves, nor do they consider others, they only do, only are. They are like a beam of light flying through the galaxy without a thought for anything or anyone, not even itself, only ever looking forward, only on its single trajectory. The beam is so intently focussed on being whatever it is, going wherever it is going, that it cannot perceive anything at all, anything outside of its trajectory. It is, at its purest state, oblivious to everything. This is why those with Autism suffer from learning difficulties, which are actually abilities to discern/contrast two or more things in the surrounding environment. It also explains why they suffer from colour blindness aswell. If you imagine yourself standing on a straight road (say an American freeway in the midwest), wearing blinkers, focussing on the white line in the middle of the road as you walk along it, you will have difficulty seeing or understanding anything outside of your line of sight. And that which you do see is going to contrast heavily with everything else, because you see fewer things, thus that which you do see will be more distinct/unique compared to other things.
I would speculate that those who founded or wrote for belief systems that are based on a highly dualistic basis, may, may, have had a higher degree of this condition than those who founded or wrote for other belief systems. This is because of the single mindedness of the person, which means that the contrasts that they perceive are greater than for other people, who would be more inclined to found or write for relativistic or polytheistic belief systems. They would also contain other attributes that are associated with those who have ASM, such as highly developed (excellent) doctrines (a result of single mindedness), and a high degree of mathematical or logical doctrine (a result of their desire to understand the cosmos).
Do not make the mistake of considering that because a particular personality type founded a religion that means that it can be dismissed as wanting in logic or truth. Indeed it because such people abide in the desire/love of truth, that they wish to understand it as fully as they can, and make it known to the wider world.
Communication is also difficult for those with ASM for two reasons: firstly, two have someone standing infront of you asking you questions, getting you to respond is asking the person with ASM to react, to respond according to the questionner, aswell as obstructing their path (both physically and mentally). Which obstructs the ASMer, preventing them from continuing along their trajectory, their choice, their will. This means that when you speak to anyone with ASM, you should avoid 'yes or no' type questions, and have open ended questions that allow the ASMer to express/develop their own opinion on the subject (thus allowing them to keep on running in a straight line, and not into the wall, or down the sideroad that you've placed infront of them). Secondly, communication requires the person with ASM to have a broad spectrum of points of reference, of experiences, views and such like, and, as ASMers are wholly dedicated, set in their ways on their own path, they find it hard to relate to others. Thus communication is difficult unless the person and the ASMer have common points of reference.
The words 'I' and 'You' are also difficult for the ASMer. This is because the ASMer is dedicated and set along their path, their direction, which is singular; due to this singularity of view, it is harder for the ASMer to get perspective, to have some form of mental dualistic comparative structure by which to compare one thing to another.
In short, ASMers are active, not reactive, which means that you should position yourself relative to them, appease their needs, fuel their growth. And whatever you do, do not obstruct them under any circumstances, allow them to continue along their own path. If you do block them, then they will either try to remove the blockage (either you or your opinions), or revert into themselves, which could either manifest as withdrawl, introversion or possibly depression. All things must be permitted to express their own nature, their own will, their own character.
