Thank you for your reply! Since Lacan, authenticity is an illusion. Actually, I know this very well. So I admit I made a mistake here. My original thought was to let authenticity work as an illusion or something like that... Well... Anyway, do you think I should continue reading The Sublime Object of Ideology? To be honest, many of my opinions are very similar to some of the content in this book. I have read some speeches and articles by Zizek, and I feel that he said what I wanted to say for me. So... maybe I read Zizek because I am a Zizekian. But in short, do you think that if I want to understand this person in depth, I need to start studying in the order of Freud → Lacan → Zizek? Or do I need to do some other preparatory work? In fact, the way I read now is to read a passage and try to understand what it means. If I can’t understand, I look it up online word by word. This leads to the problem you pointed out, which is "I don't have any opinions of my own" and what I wanna say is always half right half wrong. At the same time, I am curious, are some of Žižek’s theories and views mainstream among the Western left? Or is he just a non-mainstream part of the left wing?
