I’d say the one he hasn’t written 30 times is Less Than Nothing, but I haven’t read any of his other works so maybe I’m wrong.
I read the description of it when I was reading a couple other of his and convinced myself it was very much a repeat/expansion of the same idea. My first of his was about Schelling called “The Indivisible Remainder” and those two seem identical to me in content, except the form is an approach from 2 different philosophers to get to Zizeks ideas.
