In everyday speech, people use the information they gain in order to expand their level of knowledge. In what way this expansion takes place depends on the person who possesses information and what he chooses to do with it. He or she can for example hear about a theory, and decide if he or she wants to adapt it to his or hers knowledge.
This way, facts and theories work as building bricks in a wall of knowledge, and you have to choose on which areas you want to expand this wall. Sometimes, when facts and theories become refuted, a brick disappears in the fundament of a wall and the wall falls down and must be rebuilt with other theories and facts as a point of support.
To have a common sense is closely related to knowledge. It is the starting point of its expansion, and a point for further individual development. Therefore, the common sense is essential to accept on a daily basis, in order to be able to communicate with other people and to expand one’s horizons. The common sense is also a way to define normality, even though there can be no exact definition of what a normal person is, since everyone owns the ability to think for themselves and therefore are different from each other. Still, the common sense can be looked upon as a norm for normality and how people must act to behave in proportion to others in a society, and in order to expand their knowledge.
In conclusion, we can say that everyone has their own knowledge, but that this knowledge is fragile. If a person wants to expand his or hers horizons and knowledge, he or she must be able to accept theories or facts as genuine and use these as a fundament for further development and learning. This leads to the fact that knowledge is fragile, in the way that if the fundamental common sense and knowledge can be disproved and rejected, a whole branch of a person’s knowledge is torn down and must be rebuilt. In the end, it is all a matter of how solid you can build up your wall of knowledge, and what materials you use during the construction.
