They cooperate but I don't think they can fold into each other
  neatly like Russian nesting dolls. There's systems at one
  perspective that are invisible from another perspective. I think
  a unified Science is a bit of a nice dream but I think we're
  much further away from that as a realistic possibility - not for
  a very long time. Besides, the sciences and humanities have to
  start bridging better. A good example is history. Have you ever
  see scientific views of history? They're just awful. They
  oversimplify and miss so much. It's not that a singularly
  focused viewpoint isn't valuable to consider (such as an
  elaborate proof that "This is the cause of (some historical
  event)" but it has to ignore so many other factors that its
  value is limited. == Here's a recent example of ridiculousness:
  Proofs that Global Warming is THE cause of Syria's current
  problems. It's not that it's purely invalid as a proof. It *can*
  be proven _if_ one ignores a lot of other factors and focuses
  singularly on one particular cause that leads to the results by
  fitting matching factors in the middle of the story. It's
  ridiculous. Contributing factor? Sure. Some correlation? Sure.
  Causation? Ridiculous.
