Madeleine L'Engle, Two-Part Invention: The Story of a Marriage

"We do learn and develop when we are exposed to those who are greater than we are. Perhaps this is the chief way we mature."

"Love of music, of sunsets and sea; a liking for the same kind of people; political opinions that are not radically divergent; a similar stance as we look at the stars and think of the marvelous strangeness of the universe - these are what build a marriage. And it is never to be taken for granted."
