You touch on several things here that I'd like to discuss but might wait for a more appropriate thread.
In every real way it might be said there aren't seven thousand languages but rather 7 billion because we each have different models and beliefs. 3% of physicists believe a plane can't take off from a conveyor belt. Obviously his models differ in significant ways from all the rest. He didn't learn and incorporate permanence of perspective. Anyone can misthink and these guys are sharp enough that it's little more than just this but what about aviation engineers. These guys are sharp too. But maintaining a single perspective isn't important in designing aircraft. It's a little more important in flying them because seat of the pants flyers don't live long and pilots do even worse. I suppose if you know better than to use the seat of your pants you'll be OK.
The left brain right brain thing is something I've thought a lot about. I think you're most probably right that people before babel used both sides and their functions were identical or nearly so. I too use both sides almost the same but I must talk and communicate left brained.
Thanks for the post, again. It makes me think.
Human language is subjective since there are very few natural cause and effect association, between word sounds and the object/action/modifier, it represents. For example, the cat does not make any noise that sounds like the word cat. Why do we use that noise to label a cat? Wouldn't meow be closer to a natural sound for a cat and thereby, could naturally represent the cat? The sound choice is arbitrary and can be replaced by any other sound you want. Once a group agrees on the sound label, we creates a subjective cause and effect and we can transfer thought. But there is still that subjective matrix, so a meeting of the minds may not be perfect. This imperfection allows for subjective creativity and even opinions.
How to Say Cat in 70 Different Languages - LexiGlobe
There is a universal language that we call vision and sight. If we had a group of objects on a table, and I gather the 70 people above, that each labels the cat with a different sound, they could all visualize the cat and point to it, even though they may not understand the other 69 sounds I make. There is an arbitrary sound, but also a distinct visual attachment. We use a blend of subjective and objective.
Vision, as a language is based on the light; photons, reflected and emitted by objects that reach the eyes and are processed by the brain. There is a natural alphabet of colors, textures, shapes, smoothness, reflectivity, etc, that is not man made and is collective to all humans. Th caveman would notice the shiny gold rock. A picture is worth a thousand words, since objectivity of sight, often means more than an approximation caused by words. This is why in science, even if you publish, the last step will be others reproducing your results, so they can see for themselves. The latter, is the natural gold standard for all humans.
Dreams are sort of interesting in that they tend to use mostly the universal visual language. The brain; unconscious, is using the same pathways as the eyes, but is starting the visual language process within the brain using ionic currents. Dreams use to be more important since they speak the universal languages of the eyes and others senses and minimize the subjective language of words.
My brain was always wired differently, in the sense, I forget names, but I can remember the visuals and what was said, since wha was said would induce my inner vision, and I could describe based on my induced visual storage; paraphrase. When I create new ideas, my brain uses the visual vocabulary for processing,I then put that into written language, due to the visual symbols of written language. I would be harder of me to explain the nuance, with just spoken language, since new ideas will have a subjective wall to overcome that would be easier for me to show than to tell.
This topic is connected to human consciousness evolution, since communication is how knowledge grows and the brain operating system updates; evolves. It has a sense of direction; more sophistication. The spoken language matrix, by not being natural, is also a way for consciouses to depart from the DNA, and evolve like a separate branch, but attach to the genetic tree.
