"How could a pain follow a pleasure if a thousand tiny pains or, rather, half-pains were not already dispersed in pleasure, which will then be united in conscious pain? However abruptly I may flog my dog who eats his meal, the animal will have experienced the minute perceptions of my stealthy arrival on tiptoes, my hostile odour, and my lifting of the rod that subtend the conversion of pleasure into pain. How could a feeling of hunger follow one of satisfaction if a thousand tiny, elemental forms of hunger (for salts, for sugar, butter, etc.) were not released at diverse and discernable rhythms? And inversely, if satisfaction follows hunger, it is through the sating of all these particular and imperceptible hungers.
"Tiny perceptions are as much the passage from one perception to another as they are components of each perception. They constitute the animal or animated state par excellence: disquiet. These are "pricklings," or little foldings that are no less present in pleasure than in pain. The pricklings are the representatives of the world in the closed monad. The animal that anxiously looks about, or the soul that watches out, signifies that there exist minute perceptions that are not integrated into the present perception, but also minute perceptions that are not integrated into the preceding one and that nourish the one that comes along ("so it was that!")."
