Recognising the specificity of writing, glossematics did not merely give itself the means of describing the graphic element.
It showed bow to reach the literary element, to what in literature passes through an irreducibly graphic text, tying the play of form to a determined substance of expression. If there is something in literature which does not allow itself to be reduced to the voice, to epos or to poetry, one cannot recapture it except by rigorously isolating the bond that links the play of form to the substance of graphic expression. (It will by the same token be seen that “pure literature,” thus respected in its irreducibilty, also risks limiting the play, restricting it. The desire to restrict play is, moreover, irresistible.)
This interest in literature is effectively manifested in the Copenhagen School. It thus removes the Rousseauist and Saussurian caution with regard to literary arts. It radicalises the efforts of the Russian formalists, specifically of the O.PO.IAZ, who, in their attention to the being-literary of literature, perhaps favoured the phonological instance and the literary models that it dominates.
Notably poetry. That which, within the history of literature and in the structure of a literary text in general, escapes that framework, merits a type of description whose norms and conditions of possibility glossematics has perhaps better isolated. It has perhaps thus better prepared itself to study the purely graphic stratum within the structure of the literary text within the history of the becoming-literary of literality, notably in its “modernity.”
