To speak of a subject, no matter whether it be to deconstruct its modern form and its traditional predicates (self-consciousness, freedom, independence, autonomy, etc.) by demonstrating its transcendental derangement, or whether it be to confront it with the ineluctable obligation to judgement, resoluteness and its rational grounding, demands that the subject be thought as the arena of undecidable conflict between decisiveness and undecidability, autonomy and heteronomy, precipitancy and postponement.
