Tim Dean provides a remarkable cogent and coherent introduction to Lacanian psychoanalysis, and makes some pretty stunning arguments about queer theory and activism. In my reading group on Lacanian psychoanalysis, we recently read his chapter entitled "How to Read Lacan". I was quite impressed with this book, and would recommend it for anyone interested in high (aka frenchified) gender theory, or anyone getting into Lacan and psychoanalytic theory.
Unfortunately, however, there are some serious downsides. Tim Dean sides with Catherine Millot in condemning trans women as psychotic (fuck you too) and comes across, overall, as an asshole. I definitely wouldn't want this man over for dinner. As a trans woman very interested in Lacan, I find Dean and his cohort to be a sad and sickening bunch.
