Writing in mediation: "The word flies, the writing stays"

An architect by training, I currently work as a mediator. A question I am often asked is why an architect became a mediator? The profession of architect is not only about drawing plans. It requires a lot of "feeling" to understand what the clients want. The architect must be able to detect the need underlying the request. We are permanently between the clients, the contractors and the administrations. The architect is therefore, by virtue of his function, also a mediator. The architect's ideas become concrete in drawings. As far as writing is concerned, it is the transposition of its meaning into signs. Does the result of a mediation have to be written? For me, there is no binary answer to this question. I would therefore say neither yes nor no. Writing implies the capacity of man to pass from language to its conversion into symbols having for object to convey the word and to share it.
