A note on Lyotard and the sublime by Emmanouel Aretoulakis. He says:

Kant's insight regarding the irreconcilability of imagination and reason is the stepping stone for Lyotard's forwarding of the sublime presence of an unconscious desire to postpone meaning and delay the process of signification. The differend mediating the link between representation and concept unfolds a sublime kind of heterogeneity which breaks down the harmonizing act of representation as conducive to transcendent meaning through language. The differend, to the extent that it creates "noise" and dissension in the communicative act, brings about a formless mass of statements and open-ended signifieds that cannot be unified by a common metalanguage. In a sense, there can be no unified ego or identity for a text insofar as the text itself necessarily bears witness to the irrepressible forces within it: forces that demand a voice.
