Abstract
In this paper I consider Derrida’s anathematization during the 1992 "Cambridge affair" in the light of the 1270 and 1277 condemnations of unorthodox philosophical theses by the bishop of Paris, Etienne Tempier, the inventor of double truth. In particular, I compare these two occurrences through a reading of modernities as a re-centring on the new orthodoxy of naturalistic ontology, which began to take place in the 17th century. After the Humean attack, Kant recast such a naïve naturalistic objectivity into a more defendable shape, by internalizing the supposed universal spatio-temporal structure of Newtonian physics as transcendental conditions of possibility. Though the Kantian ontological and theological legacy is still detectable in Derrida's quasi-concept of iterability, Derrida's theoretical contributions well exceed metaphysical discourse. More generally, I argue that during the last fifty years these contributions, together with contemporary reconsiderations of modernities, produced an emerging theoretical region. Within this region, the metaphysical chain of substitution of centre for centre is displaced, so that we can evaluate practices of exclusion without having to rely on alternative injunctions.
