Study of Existentialism

I find existentialism very fascinating, as most of you probably already know. I've put aside my study of Anarchy vs. Control in the realm of Governing bodies. In it's place I've started reading the Gun book that I mentioned earlier, along with Thomas Payne's The Age of Reason. I'm still pounding through Les Miserables, which is still pure joy to read every time I pick it up. I'm reading it through an existentialist lense, I'd say, and I'd also really like to pick up "Do Androids Dream of Electric Sheep?" by Philip K. Dick and maybe some Jean-Paul Sartre. I like having personal studies.
