As for box 9, it encompasses another complex series of intensional operations andalong with box 8represents the intensional counterpart of box 10. Since the theory of possible worlds has been proposed just in order to solve intensional problems by translating them into extensional terms, I suspect that the two horns of my dilemmatic diagram are in the last analysis reducible to one another.
I record in box 9 'ideological' (or axiological) structures, such as Good vs. Bad, Positive vs. Negative, True vs. False, or even (à la Greimas) Life vs. Death and Nature vs. Culture. I wonder whether the extensional world structures can be reduced to such elementary oppositions or not: undoubtedly in certain texts one is dealing with possible textual worlds where the involved properties are exclusively of this type.

Notice that, within Greimas' intensional framework, actantial structures are influenced (overdetermined) by so-called modalities and imputed truth values (veridiction) (see, for instance, Greimas, 1973:165; 1976:80). These operations are the intensional reverberation of the assignment of truth values in box 10: given relations at the actantial level are considered insofar as they are textually predicated as true or false, and depending on propositional attitudes of the characters, equally predicated by the text.
At this point intensional approaches (mainly performed by the semiotics of narrativity) and extensional (modal) approaches (mainly adopted from the logic of natural languages) seem to overlap each other. What differs is the type of formalization these problems undergo in different theories, and, at the present state of the art, every attempt to merge these diverse approaches risks giving rise to misleading contaminations.
The only thing which is clear is that these deeper levels are not a mere terminological figment, since every reader is moving within box 9 when making interpretative decisions about the ideology of a given text, and within box 10 when making decisions about the credibility of the reported events and of the beliefs, lies, or wishes of the characters. Chronologically prior to the development of such efforts in formalization, my essays on Superman (Chapter 4) and Bond (Chapter 6) are dealing only with the ideological oppositions to be detected at the deepest intensional levels, although in the case of Superman there is also the problem of mutual accessibility among possible worlds.
0.8.5.
As far as the problem of the textual levels is concerned, one could say that there are more things in a text than are dreamt of in our text theories. But there are also fewer things than are dreamt of. The structure of the compositional spectrum of a given sememe is the same as the structure of a frame and of the actantial structure. The world struc-
