Here, there are no longer any forms or developments of forms; nor are there subjects or the formation of subjects. There is no structure, any more than there is genesis. There are only relations of movement and rest, speed and slowness between unformed elements . . . There are only hecceities, affects, subjectless individuations that constitute collective assemblages. Nothing develops, but things arrive late or early, and form this or that assemblage depending on their compositions of speed. . . . It is necessarily a plane of immanence and univocality. We therefore call it the plane of Nature, although nature has nothing to do with it, since on this plane there is no distinction between the natural and the artificial. However many dimensions it may have, it never has a supplementary dimension to that which transpires upon it. --Gilles Deleuze
