"The move from a structuralist account in which capital is understood to structure social relations in relatively homologous ways to a view of hegemony in which power relations are subject to repetition, convergence, and rearticulation brought the question of temporality into the thinking of structure, and marked a shift from a form of Althusserian theory that takes structural totalities as theoretical objects to one in which the insights into the contingent possibility of structure inaugurate a renewed conception of hegemony as bound up with the contingent sites and strategies of the rearticulation of power."
UC Berkeley Professor Judith Butler is (yawn) another one of those Jewish academics who hates Israel. I got a taste of her in March 2015 when she came to speak at UC Irvine.( I videotaped the performance and asked her a critical question regarding the crowd of Jew-haters she has aligned herself with.) Not satisfied with her answer, I sent her a letter further expounding on my question. Of course, I received no response.
The below article on Butler by SeeThruEDU gives an insight into Butler's "clogged" thinking.
Judith Butler. Unfortunately, just another face in the crowd at UC Berkeley.
