Let’s be honest: Zizek is a strange dude, but wow is he an amazing philosopher!
“The inherent obverse of ‘Be your true Self!’ is… the injunction to cultivate permanent refashioning, in accordance with the postmodern postulate of the subject’s indefinite plasticity… in short, extreme individualism reverts to its opposite, leading to the ultimate identity crisis: subjects experience themselves as radically unsure, with no ‘proper face’, changing from one imposed mask to another, since what is behind that mask is ultimately nothing, a horrifying void they are frantically trying to fill in with their compulsive activity.”
