To see the earth as it truly is, small and blue and beautiful in that eternal silence where it floats, is to see ourselves a riders on the earth together, brothers on that bright loveliness in the eternal cold—brothers who know now they are truly brothers.
— Archibald MacLeish, American poet, 'Riders on earth together, Brothers in eternal cold,' front page of the New York Times, Christmas Day, 25 December 1968
