Hägglund on the Logic of Derrida

In the video below, philosopher Martin Hägglund reads excerpts from his book Radical Atheism: Derrida and the Time of Life (2008), and argues that the unitary logic of Jacques Derrida's philosophy shows itself with notions such as "auto-immunity" and "trace".  I'm not sure I follow his arguements here (or the relevance to anyone other than hyper-literary types), but it is interesting trying to follow along with his meandering assertions.  The video was shot in October of 2008 at Cornel University.

Description of the book from the publisher:

Radical Atheism presents a profound new reading of the influential French philosopher Jacques Derrida. Against the prevalent notion that there was an ethical or religious "turn" in Derrida's thinking, Hägglund argues that a radical atheism informs Derrida's work from beginning to end. Proceeding from Derrida's insight into the constitution of time, Hägglund demonstrates how Derrida rethinks the condition of identity, ethics, religion, and political emancipation in accordance with the logic of radical atheism. Hägglund challenges other major interpreters of Derrida's work and offers a compelling account of Derrida's thinking on life and death, good and evil, self and other. Furthermore, Hägglund does not only explicate Derrida's position but also develops his arguments, fortifies his logic, and pursues its implications. The result is a groundbreaking deconstruction of the perennial philosophical themes of time and desire as well as pressing contemporary issues of sovereignty and democracy.
