Oh I can show what nothing is poetically. Whether you agree that
  it is nothing that I am showing you would be an issue, but such
  is the same with mathematics or philosophy or anything a human
  attempts to convince another human of. Square circle is doable
  as well. Again - depends on the constraints of the system. You
  might not LIKE my examples of square circles but they'll be
  correct, because I will have shifted the context.
