Dear Vladimir!
Thanks you for reading my long comment, and further looking after.
Sorry if there may be misunderstanding due to I haven't any knowledge about "protogeometer'. I did some looking after, however it is some 'gap' in my apprehension, in this sense.
In a broader view, I can also understand the mathematics and physics would be the highest abstraction languages with which relation and transformations of the spirit=(inherent)consciousness and physical body(as a vehicles of consciousness) would be described, giving more refined interpretation how the memory works through a medium we call - mind.
However, I a bit disagree, putting the 'image of 'man' somehow equal with an abstract symbolic systems. This is 'rigid' interpretation only, which can put outside one his own thoughts, who actually wish to conceptualize and describe the fundamental meaning through very himself..
This is a long time problem with remarkable thinkers, they are inclined to think out of his actual bodies. Simply said, they forget they are in a complex physical body meanwhile they are doing any kind of abstraction to describe, apprehend the fundamentals! So, even they may be at a highest level of understanding of the basics, even they can lose his humanness closer to an everyday man, during this process. This is bigger danger, than do not understand quite exactly the fundamentals! I only tried, to point out to this in my essay too.
High regard,
Valeria
