Michel Serres’s natural contract is not merely a proposal for an alternative legal or political paradigm. It offers something deeper: a new imaginary to unsettle and confront the deep assumptions of classical social contract theories and their retrojected justification: the state of nature. The argument of this article is that Serres systematically unpicks the conditions of possibility of the contractual paradigm in the modern social imaginary, replacing them with an original noise, a primacy of parasitic relationships and a telos of symbiosis. This reframes the natural contract as the visible profile of a comprehensive social and natural imaginary that radically refigures society and ecology otherwise than on the basis of primacy of reciprocal exchange relationships between self-sufficient individuals.
