Uprisings, reversals, insurrections, revolutions, crushes, leaps forward, returns backward, stagnations are so many movements - impulses and fallouts - that permanently agitate the "social body", as if this one were indeed composed of muscles and tendons that do not cease to activate and to slacken, to pull this one in a direction or another. But one can think that there is much more than a crude vitalist metaphor behind this way of qualifying groups and societies in their turbulent evolution: there is the clear perception that a physical reality, although subtle, can alone constitute the support of a "being-in-common", even of a common movement.
The existence and subsequently the activity of a social group, of a community or even of a society must thus always be able to be conceived first of all in the sensible. It is besides the first sense of the notion of "mobilization", which means setting in motion of a collective and which alone, sometimes, allows to reveal the constitution ("to stand upright together") of a group, which, to be or at least to appear, must at least give the impression that it is ready to stand up, or even to move in the time and in the space, to set itself in motion.
Therefore, whoever wants to really understand social dynamics must necessarily look at the properly kinetic dimension of these, to be interested in how bodies that, in the last resort, compose them, coordinate and set themselves in motion. That requires a particular attention to the impulses, to the energies, to the flows which direct these physical expressions, as well as to the space which receives them and where they are printed, to the images, tracings, convolutions which they draw there.
