i never read foucault, but a lot of people in the punk music scene wrote about him and people like nietzsche.. i like nietzsche's thoughts on not being too certain about anything, like always doubting even if you have a set belief that it could be wrong. it's pretty much how i live my life with schizophrenia... there's a lot written about post modernism that is over my head though.. i just read a basic introduction to nietzsche... made a lot of sense to me... i don't know how i feel about all of it though.. i'm a terrible reader.. a lot of that philosophy stuff you kind of have to be a bit educated to understand the way it's written.
Foucault's Madness and civilization is really good imo. I fully admit that i have never read Neitzche. He never really interested me
