The Shadow of Affectivity Inside the ‘Is/Ought’ Debate’: Siniscalchi, Fuller, Manderson and Vico’s Ghosts in the Legal Machine

The article reconstructs the is/ought debate in legal theory through a phenomenological reading of the concept of normality. An analysis of Siniscalchi, Fuller and Manderson looks at the issue from the perspective of law and literature, and then applies Giambattista Vico's rhetorical methodology within the contemporary debate. The question: "is Hume's law really visible within Hume's thought?" also paradoxically poses the figure of phantoms and fictions at the heart of the current theoretical debate on law. A history of the phantom placed at the centre of the history of Western institutions still remains to be written, but a comparison of very diverse and incongrous approaches such as the extended order of Hayek, the dogmatic anthropology of Legendre, the eunomics of Fuller and the new science of Vico shows how the mystery of consciousness and the mystery of institutions are inextricably entwined. It is impossible at the moment to draw a coherent doctrine from these conflicting perspectives, but their convocation is sufficient to demonstrate how the theory of law is always suspended between the unknown and the human attempt to inhabit it, moving us toward an affective turn that has yet to be fully conceived in the theory of law, following the iconic turn. The anthropological primacy of fictio and the aesthetic-legal dimension in the constitution of language is not that of a logic and separation from the body and meaning, but the exact inverse, even in the unavoidable constant tension between the two poles: logic is born through the gesture of the body that precedes it, as myth precedes the foundation of the State; the origin of the concept is affective, as Hume, and perhaps Vico himself, would have passionately affirmed.
