The breast is said to be a mammary gland deterritorialized by vertical stature; and the mouth a deterritorialized animal mouth, by the turning-up of the mucous membranes to the exterior: but a correlative reterritorialization is carried out of the lips on to the breast and conversely, so that the bodies and the environments are traversed by very different speeds, whose complementarities form continuums of intensity, but also give rise to processes of deterritorialization.
