Janis Kenderdine :D you have a way with words - and reminded me
  of my linguistics class (which was one of my favorites in
  Hampshire) - This is the distinction I keep tripping over in
  research: Forms/shapes/what-it-is-regardless-of-us-being-here
  and Function/purpose/how-does-this-apply-to-me. I don't think of
  it as a duality, but we are steeped in duality so it has been
  tricky to find ideas that aren't simply modified dualism. Heck,
  even the idea of ideas (perfected forms in the mind) is
  dualistic... and so is the word 'form' even... ugh. Hard to
  escape it. :P "
