The paper focuses on Derrida’s claim that “margins” of philosophy are made of aporias, which bring no solution to the problems that can be positively solved in the center of Western metaphysics. According to the paper’s hypothesis, Derrida’s work is characterized by a circular movement of subversive translation of idioms into aporias, operating as a gest of resistance which immediately turns back to resignation. In fact, Derrida’s aporia is no logical antinomy, it’s rather an ethical experience of decision without end. This ethics of mistrust inspires Derrida, just like Kafka, to describe the pre-ontological aporias, the logically paralytic places, where it’s impossible to formulate a problem and to propose its solution, let alone to do its critique. For these reasons − and contrary to what is often declared − deconstruction is no critique.
