One can speak instead of a coefficient of affinity that varies in degree between social machines and desiring machines, according to whether their respective regimes are more or less similar' according to whether the desiring machines have a greater or lesser chance of causing their connections and interactions to pass into the regime of the social machines; according to whether the social machines execute more or less of a movement of detachment (decollement) in relation to the desiring machines; and whether the death carrying elements remain caught in the machinery of desire, encasted in the social machine, or on the contrary join together to form a death instinct that extends throughout the social machine, crushing desire.
