You know plenty! My approach is to let them run their mouths until they, inevitably, say something stupid.I knew nothing about Hegel. Also a bit murky when it comes to Kant despite knowing hes incredibly important and influencial. Most of my philosophical knowledge is Nietzche, also know a handful about certain eastern philosophies and some Christian theological philosophy. I feel like I can grasp Nietzche much easier because he writes more like a novelist, and, at times, a satirist, rather than a dry academic
