I have expressed some reservations about Hägglund’s book in the past, but I do think it is a rather refreshing read, even if I disagree for the most part with its primary argument – here’s take on the book by Brian Rajski:
“[T]he openness to the other cannot be an ethical principle since it is not a matter of choice. Openness to the other answers to the openness to the unpredictable coming of time and is thus the condition for whatever there is. . . . Furthermore, nothing can guarantee that it is better to be more open than to be less open to the other (or vice versa). . . . The decision concerning how one should relate to the other can therefore not be dictated by an ethical injunction, but must be reinvented from time to time. Far from providing an ethical ground, the deconstructive thinking of alterity thus politicizes even the most elementary relation to the other.” In this explosive little book on Derrida, Martin Hagglund rejects the appropriation over the last twenty years of deconstruction as an ethical, political, or religious project. He denies that there is an “ethical turn” in Derrida’s thought (usually located around the publication of Specters of Marx), arguing Derrida’s work is informed by a single logic from start to end.
