For now, all we can say is that each articulation has a corresponding type of segmentarity or multiplicity: one type is supple, more molecular, and merely ordered; the other is more rigid, molar, and organized. [TP: 41]
Although the first articulation is not lacking in systematic interactions, it is in the second articulation in particular that phenomena constituting an overcoding are produced, phenomena of centering, unification, totalization, integration, hierarchization, and finalization. [TP: 41]
Both articulations establish binary relations between their respective segments. But between the segments of one articulation and the segments of the other there are biunivocal relationships obeying far more complex laws. The word "structure" may be used to designate the sum of these relations and relationships, but it is an illusion to believe that structure is the earth's last word. [TP: 41]
