The entire set of means for communicating information in a particular context is referred to as culture. Culture is possible only when individuals communicate their ideas and visions by writing them down for other people and for other times and places, pointing out the super-personal nature of culture. Of all the means of cultural exchange, writing is the most specific and precise, as well as the most flexible. A pictorial representation leaves much more room for interpretation. They are based on the same process, but the process works at different levels of consciousness.
Writing is a notation based on a language and therefore well defined.
On the other hand, deciphering written information is more complicated and demanding. Written information is useful and important only as long as it is understood correctly. As semantic systems vary over time and place, it is often difficult to understand the messages. This is also the reason for the difficulties encountered when texts are translated between languages. Therefore, languages are a very powerful as well as a very delicate means of expression.
