I was invited to a barn raising near Wooster, Ohio. A tornado had leveled 4 barns and acres of prime Amish timber. In just three weeks the downed trees were sawn into girders, posts and beams and the 4 barns rebuilt and filled with livestock donated by neighbors to replace those killed in the storm. I watched the raising of the last barn in open-mouthed awe. Some 400 Amish men and boys, acting and reacting like a hive of bees in absolute harmony of cooperation, started at sunrise with only a foundation and floor and by noon, BY NOON, had the huge edifice far enough along that you could put hay in it -- a vast work, born of the spirit.
Without faith that it is possible to render reality understandable by means of our theoretical constructs, without faith in an inner harmony of the world, there could be no science. This faith is and always will be the basic motivation behind every creative scientific idea. All our endeavors, all the dramatic conflicts between old and new ideas are supported by the eternal desire for knowledge, the unshakeable faith in cosmic harmony which becomes stronger the more difficulties loom before us.
