"I did not know the woman soul, that crowning gift of Providence to man, which, if we do not ourselves degrade it, will set an edge to all that is good in us. I did not know how the love of a woman will tinge a man's whole life and every action with unselfishness. I did not know how easy it is to be noble when some one else takes it for granted that one will be so; or how wide and interesting life becomes when viewed by four eyes instead of two." -
  --  Sir Arthur Conan Doyle
