Just pointing in the direction of Levi’s blog, and his recent discussion of flat ontology and signs. I’ve chipped in a little bit on the comments to try and clear up some of my confusion over what he means by flat ontology, so I thought I’d link it here (http://larvalsubjects.wordpress.com/2009/08/17/flat-ontology-and-signs/) rather than re-writing out some of my thoughts.
Will have something else up soon, part way through writing it but keep getting distracted.
