If we are to enter a room full of strangers, we seek a position in the room that brings comfort. Sometimes this is because we find someone we know, sometimes we are welcomed, and sometimes it's a result of unknown feelings and factors guiding us towards faces. Body actions seem to bring a silent understanding of familiarity.
Conversation flows naturally, the flow however, rather a result of earlier compatible vibes, rather than a series of strung words accepted and understood by the group.
We have entered the realm of cultural communication. Cultural communication is that silent understanding and feeling which permeates through those who are, in some strange way, similar in thought and action. Of course this is not always the case, many times our arrival in a group only isolating us further. There is is however a cultural fellowship, crossing all boundaries of race, religion, and status which cannot be explained. We are often drawn to peoples and situations who fall outside our frame of reference. Why do certain cultures fascinate us while others are to say the least, abhorrent?
Culture must have come first. It was those who liked the same cave, ate the same food, and hunted with similar thoughts who must have united and formed the socio-protective group. Language is actually irrelevant! It is the worst form of communication, because it can, if used by a so called expert, disguise the true meaning of the emotion and purpose of the person conveying the words.
Culture is a structure based on the needs, current and historical, of the group. Language on the other hand, is a means to communicate that structure. If we were all to remain silent, it would not be long before our bodies would be conveying our requirements with far greater emotion and reason. We would become experts at reading the other person and, interact in a way which carries both sincerity, and honesty.
Language arrived when we had to put names to things. The tall fellow in the group needed a name, an outstretched arm insufficient when there were suddenly two tall fellows! If however, by some trick of fate, our remonstrations could have shown a difference in the two tall fellows, then perhaps our world would still be communicating. It is very sad, but the day culture, and body language, were replaced by language, we all had to suffer the consequences of verbal interaction, and unfortunately suffer those who have replaced cultural importance, with verbal inconsequential interaction.
