<p>Intensive operators of differentiation/integration are at the core of the constitution of phenomena and of their morphological character. A variety of differential becoming shapes physical, structural and post-structural dynamics. In the first case the differential constraint is fixed by specific equations, representing nomological knowledge and universal laws. In the second case, that is structural morphodynamics, equations are fixed up to a set of parameters in a possibility space a-priori given, as in Thom catastrophe theory. In the opposite, post-structural dynamics are characterized by differentials in continuous recomposition that is the condition for a dynamic imagination of becoming. Possibility spaces are not given a-priori but emerge by the immanent intensive composition. The plane of differential composition becomes the virtual of imaginative dynamics extended well beyond discursive practice to human and non-human living being.</p>
