ABSTRACT
The aim of this chapter is to question the role which highly abstract notions of langue and similar formal schemata play in relation to the system of instantia tions or that network of discursive operations which actually takes place in communication. Even if it is not possible to liberate grammar entirely from logic, as Heidegger suggests we should, we can at least attempt to find a level of theorization closer to discursive actualities and less exclusive of other sign sys tems than is the Saussurean langue. The chapter concludes with a discussion of the semiotic corroboration thesis which says, put simply, that what we call reality is the product of the interaction of at least two different sign systems.
