Interchange I: On intention, context, and meaning, with examples
The reason Derrida does not think intentions are governing is because he thinks the condition of having a (linguistic or semiotic) one entails a form of repeatability that the intention cannot fully master. Yet there also cannot be any text-y things, written or spoken or semiotic, without intention playing some role. Moreover, as an interpreter, Derrida wants both: he wants to interpret faithfully the intention, as Henry pointed out, and read what is not available as an intention but inscribed in a text (which reading also produces). Not one or the other, but both.
