This looks to be good. Alas, I used up quite a bit of funds to go to the last objects conference. I’ll have to talk to Freelancer Extraordinaire and see what I can do since it does look good:
Real Objects or Material Subjects? A Conference on Continental Metaphysics
March 27th and 28th 2009, University of Dundee, Scotland
Keynote Speakers: Graham Harman (American University, Cairo) and Adrian Johnston (University of New Mexico)
The aim of this conference is to stage a debate between two dominant strands of contemporary continental thought, as represented by the object-oriented realism of Graham Harman, and by the transcendental materialist theory of subjectivity recently proposed by Adrian Johnston.
Along with the debate between Harman and Johnston, we hope to attract papers from both advanced graduate students and early career researchers on related topics.
Suggested topics include:
realism v. materialism, the contemporary relevance of ‘critical realism’, materialist theories of subjectivity, object oriented ontologies, the place of the political in the realism/materialism debate, the persistence of dialectical materialism, recent continental appropriations of eliminative materialism, realism and materialism in contemporary Anglophone philosophy, continental naturalism, the role of the physical sciences in contemporary philosophical materialism, the persistence of religious themes in recent materialist philosophy, the continued importance (or lack thereof) of thinking the ontological in conjunction with the political.
Abstracts of no more than 400 words should be submitted to m.burns@dundee.ac.uk by January 15th, 2010.
Do not hesitate to contact the organizers with any questions.
PHILOSOPHY IN A TIME OF ERROR 
I know this post is old now, but thanks for posting this for us! And just to add, Peter Hallward, James Williams, and John Mullarkey are all speaking as well. Should be a great time, would be great to see you there!
