I found “How to Read Lacan” by Zizek a great introduction as someone who has 0 psychology or philosophy background. As another poster mentioned Im still not sure how much “there is”, but I found the concept of the Other to be interesting. But I also don’t think it’s too healthy outside of a clinical setting to try and reduce human desire to a formula. People should try to understand each other one-on-one without diagnosing or labeling either party’s behavior. It feels like a lot of interest in Girard and Lacan stem from trying to manipulate or predict people, which may be a useful tool some of the time (doctor <> patient) but is no way to live day-to-day!
