Human communication

There is no doubt that among all species we know about, we are the ones possessing the best communication method - our languages. A friend of mine ones said that he always thought how on earth the first word describing an object has ever come out. Let us not worry about how it came out but let us say that the first word was 'ox'. An intelligent person sees a particular instance of a species and she decides that it should be called ox. Now realize everyone else in the world has no name for ox other than the person who I just described. Let us understand the problem this person faced:
1. I can call it ox, but can anyone else even pronounce this.
2. Who should I tell about it first. If she tells it to a few morons to start with, they would not care about her finding and may not even appreciate the need for a platform for communication. And every times she fails, her enthusiasm about her finding deteriorates (after all we are human beings). So she has to choose first few persons judiciously.
3. Let us say she has chosen first few persons who understand the importance of her finding. Now, if she has convinced these few persons that a particular type of species should be called ox, how every one else is going to realize that an ox is an ox.
4. This is where she realizes that she needs good artists - artists who can draw an ox in a wholesome way. Let us say, she, the discoverer of name of ox, finds a few good artists. These artists can draw a species which has a particular look and they know that it is an ox.
5. Now, a few people can call an ox an ox and a few other can draw ox in a proper way. But realize how inefficient it is to draw an ox and then tell people that you should call it ox. This is where she might have realized that we need a written form of ox that maps the picture of an ox to a few word with few letters. Let us assume that the first language was English (You can assume whatever you want, but I don't have many choices :D). Now, to write an ox she needs some building blocks.
6. The importance of building blocks (letters) can not be neglected. Let us realize that this person knows that their are other things other than ox which are to be mapped from their physical reality to some written representation. So she decides that we need an alphabet system. An alphabet system which has enough variety in it so that it can capture a lot of things but this variety should not be overwhelming (Our brains have memory limits :) ) . Now this person with the help of other persons has developed this alphabet system and defined written representation of all species.
This part, mapping physical objects to written form, was easy. I can only imagine how complex it is to define certain other nouns like passion, desire, hope, love etc. Mapping of these nouns from what is their in mind to the written words must be really complex. But somehow we all seem to understand all these words. I still feel that their are a few problems with the way we communicate, let me mention a few:
1. The problem of scale: Let me start with an example. Some one says,"My son has obtained really good grades". Now there is some grade that someone's son has obtained and according to that some one these grades are good. Now if this statement is ever told, I am almost certain that listener does not know what are the grades of the speaker's son. The reason could be that according to speaker anything above a B is a good grade but the listener may believe that nothing other than A's is a good grade. So at the end of the statement, the speaker and listener are not at the same information level.
2. The categorization problem: Two different persons can put the same object/event/thing into two different categories. An example would be blue whale. If a person with not much biology background is ever asked what type of a species a blue whale is, he is going to say that it is a fish. But biologists have categorized it into mammals. The categorization problem manifests itself, when two people have different definition of the same category. This problem is abundant in our communications. For example - some people say that India is democratic whereas certain other say that it is socialist democratic.

Conclusions: Humans are complicated. Different words have different meanings to different people. We can only hope that what we are saying is actually what the person in-front of us is getting. To me the only solution to this problem is adoption of a predictor-corrector method. Some one says something to you. You predict in your mind what he or she might mean. Now you ask back some questions and based on the replies, you correct the meaning in your head. The only problem with this method is that there is no guarantee of convergence i.e. you actually being able to decipher what someone meant.
