The poem must be the creation of a new grammar of thought by suggesting new links between words and worlds. It is therefore an original way of rethinking the link between subjectivity and objectivity in order to experience the Real. It is precisely the poetic experience of Hawad, the poet who travels in the desert and follows the horizons. His poems give shape to a liminal zone where all the “levels of reality” are interconnected and which the Romanian theoretical physicist Basarab Nicolescu calls the “hidden third” in reference to the logic of the included third. If we can say that his book, Poetic Theorems, is certainly not pure poetry, we can also say that it is not a simple set of purely scientific theorems. Nicolescu uses poetic language to express a scientific vision of the Real. I therefore propose to analyze the characteristics of this new grammar of thought through a comparative study of these two books and these two disciplines.
