Human society - man in a group - rises out of its lethargy to new levels of
productivity only under the stimulus of deeply inspiring and commonly
appreciated goals. A lethargic world serves no cause well; a spirited world
working diligently toward earnestly desired goals provides the means and the
strength toward which many ends can be satisfied...to unparalleled social
accomplishment.
