In the structural tradition, reality was primarily approached as an isotopy from the perspective of veridiction (Greimas 1977: 251), potentially in competition with other isotopies, for example, that of the aesthetic gaze with its "excesses" (Greimas 1986, p. 32). However, the question of reality cannot be reduced to isotopic passages between rationalities or regimes of meaning. Reality-for-itself (Wirklichkeit) opposes any attempt to assert a reality-in-itself (Greimas 1986: 39). Furthermore, the latter is semiotically mediated and reconstructed within institutional frameworks according to a specific discursive epistemology (Fontanille 1987). As for enunciative practices, the cooperation between a writer and his reader, like other interactions, seeks to provide a plan of "reality as comfortable, as acceptable as possible" (Greimas 1986: 59).How can contemporary semiotics coherently meet these multiple demands of accounting for reality? Semiotic mediations do not seem to be exploited to construct exclusive and self-referential horizons of reality; rather, they are used to explore participatory or translatable realities. Our intervention then aims to semiotically conceive reality as an ecological framework of modal transpositions through which proportions are chosen to allow an interweaving between differentiated circuits of meaning (subjective, interactional, and institutional). Semiotic mediations help compose reality, but also reveal, in negative, the scenarizations of meaning in which the real is far from being domesticated and mapped.
