"We're all made of Star-Stuff" - Krauss? *Carl Sagan? *Nope.
  *They copied.
  1918: the President of the Royal Astronomical Society of Canada,
  Albert Durrant Watson:
  It is true that a first thoughtful glimpse of the immeasurable
  universe is liable rather to discourage us with a sense of our
  own insignificance. But astronomy is wholesome even in this, and
  helps to clear the way to a realization that as our bodies are
  an integral part of the great physical universe, so through them
  are manifested laws and forces that take rank with the highest
  manifestation of Cosmic Being.
  Thus we come to see that if our bodies are made of
  star-stuff,*and there is nothing else, says the spectroscope, to
  make them of*the loftier qualities of our being are just as
  necessarily constituents of that universal substance out of
  which are made
  *Whatever gods there be.*
  We are made of universal and divine ingredients, and the study
  of the stars will not let us escape a wholesome and final
  knowledge of the fact.
