80 42 RESUSCITATING TARDE’S DIAGRAM Although Latour gainfully uses this quotation to dissect Tarde from individualism (and, in doing so, traces the network by looking for the actors, and in turn, understanding actors through the networks in which they are traced), the biological and psychological blurring of the self and other in social encounters seems to be purposefully avoided, perhaps in case it resides too closely to a psychoanalytical perspective or a modern-day interpsychology. As I will argue, a drift back to both a psychoanalytical unconscious or interpsychology is indeed incompatible with Tarde’s diagram, but its appeal to somnambulism nonetheless infers an unconsciousness of sorts not accounted for in the associative network model.

60 The organic glue that brings the social together is, in this light, a homeostatic process regulated by anomie, social facts, and the downward influence of collective intelligence. In contrast, Tarde’s epidemiological diagram positions the imitative ray as the pervasive factor—the elephant in the room, if you like. Unlike Durkheim’s top-down determinism, Tarde appeals to the contagiousness of point-to-point social encounters, continuously adapted by local contingencies. Significantly, Tarde does not completely dismiss the idea of social wholes but argues that the whole is a manifestation of habitual repetitions of social invention and imitation prone to the occasional monstrous contagion.

The point of drawing attention to the machinic processes at the core of both Tarde’s and Deleuze’s diagrammatics of desire is to stress their significant place in a counter-neo-Darwinian concept of cross-hybridization, or what I will go on in this book to describe in the concept of viral love (see chapter 4). The main focus for now, though, is placed on Deleuze and Guattari’s prominent account of the crosskingdom lovemaking of the wasp–orchid assemblage and how it in turn relates to a decentralized power functioning in Tarde’s diagram.
