Le livre de Salah Natij, La Th orie du Bayān d'al-Jāḥiẓ d'une herm neutique de la nature une s miotique de la culture constitue la premi re tude d'ensemble enti rement consacr e la th orie du Bayān (communication, herm neutique, s miologie) labor e au milieu du IXe si cle par l'encyclop diste et polygraphe arabe al-Jāḥiẓ (m. 255 H./ 869). Il s'agit d'un ouvrage qui restitue la th orie jāḥiẓienne du bayān son originalit en montrant qu'elle ne constitue pas une simple rh torique langagi re ( Balāgha ), ayant l' nonc verbal (Lafẓ) comme unique objet, mais une perspective herm neutico-s miologique qui tudie non seulement la parole (lafẓ), mais galement tous les types de signes que les tres vivants, humains et non humains, produisent, mettent et utilisent pour communiquer ou s'adapter leur environnement de vie. Salah Natij's book, Al-Jahiz's Theory of Bayān: From a Hermeneutics of Nature to a Semiotics of Culture is the first comprehensive study entirely devoted to the Bayān theory (communication, hermeneutics, semiology) elaborated in the middle of the ninth century by the Arab encyclopedist and polygrapher al-Jāḥiẓ (d. 255 H./ 869). It is a work that restores to the Jāḥiẓian theory of bayān its originality by showing that it does not constitute a simple linguistic rhetoric (Balāgha), having the verbal statement (Lafẓ) as its sole object, but a hermeneutic-semiological perspective that studies not only speech (lafẓ), but also all types of signs that living beings, human and non-human, produce, emit and use to communicate or adapt to their living environment.
