The audio of both responses from Paul Ennis and Michael O’Rourke to Levi Bryant’s talk “Two Ontologies: Posthumanism and Lacan’s Graphs of Sexuation” at Independent Colleges Dublin on 3 July 2012 is now available on You Tube.

My response to Paul Ennis begins here: http://terenceblake.wordpress.com/2012/07/23/paul-enniss-non-laruellian-response-to-levi-bryant-1/
NB: Paul took umbrage at the style of my response, so in the 4th installment I toned it down and gave a rational reconstruction of part of my argument, but aside from this initial reaction to the style he never responded to the substantial content.
