 For orientation purposes, it’s useful to consider Gilbert Simondon’s theory of individuation as a very simple model for what Deleuze calls “actualization.” For Simondon, crystallization is a paradigm of individuation: a supersaturated solution is metastable; from that pre-individual field, replete with gradients of density that are only implicit “forms” or “potential functions,” individual crystals precipitate out. The Deleuzean virtual is composed of “Ideas” or “multiplicities” involving differential relations among heterogeneous components, whose rates of change are connected with each other. For an example of such heterogeneity, let us return to hurricane formation, the Idea of which we sketched above. Here it should be intuitively clear that there is no central command, but a self-organization of multiple processes of air and water movement propelled by temperature and pressure differences. All hurricanes form when intensive processes of wind and ocean currents reach singular points. These singular points, however, are not unique to any one hurricane, but are virtual for each actual hurricane, just as the boiling point of water is virtual for each actual pot of tea on the stove. In other words, all hurricanes share the same virtual structure even as they are singular individuations or actualizations of that structure.
