Why it is that all who have turned out to be outstanding men of
  science or politics or literature or the arts are apparently of
  melancholic temperament. - Seneca, claiming Aristotle said it
  300 years before but no corroborating proof from Aristotle's
  time remains...

  would be more accurate... but that's not the kind of thing
  that's sharable in Meme form... and really, the form we have
  inherited is close enough. I like the emphasis in the original
  on "black biled" which means today's "manic-depressive". I like
  that better than "madness". ===== Crap. It was Seneca the
  younger, about 300 years AFTER Aristotle died who said that
  Aristotle said something similar. Dang it. _so close_... *dang
  it*. Ben Jonson the playwrite trusted Seneca at his word.... but
  it was already 1600 years later and 1900 since Aristotle... so
  it's forgivable I suppose... but now we're 2300 years past
  Aristotle... *sigh*.

  At long last, harrisimo02, thanks to the kindness of an old
  friend (Prof. Edwin Floyd at the University of Pittsburg), we're
  able to give you the text of "Aristotle" that you requested.
  Introducing his 30th "problem," the author raises the question,
  ??? t? p??te? ?s?? pe??tt?? ?e???as?? ??d?e? ? ?at? f???s?f?a? ?
  p???t???? ? p???s?? ? t???a? fa????ta? *e?a???????? ??te? "Why
  it is that all who have turned out to be outstanding men of
  science or politics or literature or the arts are apparently of
  melancholic temperament."
  [In those days, "melancholic" (literally, "black-biled") meant
  pretty much what we mean by "depressive" or "manic-depressive"
  today.]
  Boiling the sentence down to its core, we have the statement
  that Seneca focused on, and that you wanted to discover: All who
  have turned out to be outstanding men are apparently of
  melancholic temperament which, in Greek, is

  p??te? ?s?? pe??tt?? ?e???as?? ??d?e? fa????ta? *e?a????????
  ??te?, or, in caps,
  ?????S ?S?? ???????? G?G???S?? ?????S F???????? ????G???????

  My faith in Memes is slightly restored! After fighting bad Tesla
  quotes for days... _so nice_ to see a potentially accurate one!
