It will have been remembered that the objective in this reflection was to specify the true relations which exist between literature and existential universe. Contrary to our predecessors who have practiced simplistic, block, or even very blurred relationships, we have tried to clearly specify that there are four sources of inspiration from which writers produce their works: on the macrostructural level, we have noted that there are two of them, namely the Romanesque and the Existence. However, we also found that on the microstructural level, each of these two major sources is divided into two: from the point of view of the Romanesque, there is nothingness and nonsense; from the point of view of Exis- tence, there is the writer's life and everyone else's. The first two parts of the reflection have devoted the careful study of these four sources.
