So a lot of philosophical writing references a sort of general canon, at least as far as western thinking is concerned. Other traditions I'm sure have their own details but I can't speak intelligently to them. The field is enormous, and without more specific information regarding your goals it is difficult to pinpoint the classics in subfields that may interest you. That said, there are a few highlights I think you'r…
These are are probably the most significant works of Continental philosophy, and should definitely take precedence of Foucault, who's really the only representative of Continental philosophy (with the exception of maybe Hegel) on your list.
It should also be made clear that plato.standford.edu is a highly biased site that mostly depicts philosophy from an Analytic perspective, where Continental thought is barely represented (or misrepresented).
NOTE: As I tried to make clear in a later post in this thread, I'm not recommending Heidegger or Nietzsche for a beginner. I just think their works belong on the list of the person I replied to more than do a lot of the other people he lists (many of whom, by the way, also aren't good for beginners to start with).
