Reinhold Niebuhr, in a sermon in 1943 quotes
"God, give us grace to accept with serenity the things that cannot be changed, courage to change the things which should be changed, and the wisdom to distinguish the one from the other."
That men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.
Such prosperity as we have known up to the present is the consequence of rapidly spending the planet's irreplaceable capital.
"God, give us grace to accept with serenity the things that cannot be changed, courage to change the things which should be changed, and the wisdom to distinguish the one from the other."
