In this first of paired chapters bearing down on the evolutionary history and philosophy of literary language, Victorian narratives differently concerned with the term “medium” – George Eliot’s The Lifted Veil, Oscar Wilde’s The Picture of Dorian Gray – undergo an intensive reading that opens directly onto Giorgio Agamben’s investigations into the always mysterious ontological conjuncture of idea and its sayability, object and its name, in human discourse – and since then onto conceptual poet John Cayley’s theory of “grammalepsy.” Literary examples of prose under duress, from Herman Melville to D. H. Lawrence, return reading to a more close-grained application of Agamben’s poetics (rather than ontology), where the “give” – and take back – of a medium’s oscillatory potential can only be played out before us, tacitly at least, in a foundational contrast to the logic (following Agamben) of the non-extensive point in calculus, the signifying unit that has, unlike syllabic language, no subsidiary elements.
