yes, to me is a categories problem. Not the categories
  themselves per se; they can be useful, but rather the 'hard
  lines' put inbetween them. They're useful distinctions; and
  sometimes it's important to emphasize them yet without
  forgetting that the lines between them are rather fictional in
  nature, having more to do with approach (methodologies) and the
  language used because, in the end, if you send 150 different
  disciplines to study something, what do you get in the end of it
  all? What's being studied?
