Epistemology is a bit overrated. The current state of things in academic philosophy is needlessly... obtuse. I love philosophy and even I find it difficult to get into -- lots of smart people picking holes in eachother until there's practically nothing to stand on. Ironic, given the subject matter, but ultimately you just have to pick a schema that you like and go with it. Ultimately, whether you can know anything for certain or not is a bit of a meme -- you have to believe in things regardless.
