 Deleuze talks about this effect of sensation as the “transcendent exercise” of the faculty of sensibility; here we could refer to the third chapter of Difference and Repetition, where Deleuze lays out a non-Kantian “differential theory of the faculties.” In this remarkable theory, intensity is “difference in itself,” that which carries the faculties to their limits. The faculties are linked in order; here we see what Deleuze calls the privilege of sensibility as origin of knowledge—the “truth of empiricism.” In the differential theory of the faculties, sensibility, imagination, memory, and thought all “communicate a violence” from one to the other. With sensibility, pure difference in intensity is grasped immediately in the encounter as the sentiendum; with imagination, the disparity in the phantasm is that which can only be imagined. With memory, in turn, the memorandum is the dissimilar in the pure form of time, or the immemorial of transcendent memory. With thought, a fractured self is constrained to think “difference in itself” in Ideas. Thus the “free form of difference” moves each faculty and communicates its violence to the next. You have to be forced to think, starting with an art encounter in which intensity is transmitted in signs or sensation. Rather than a “common sense” in which all the faculties agree in recognizing the “same” object, we find in this communicated violence a “discordant harmony” (compare the Kantian sublime) that tears apart the subject (here we find the notion of “cruelty” Deleuze picks up from Artaud).
