In human relations, to know where we are, you must know here we have been. Only by knowing both, can you begin to understand where we are going. Trying to understand history is like trying to comprehend the world while in a sand storm because we are so much a part of it, in our own tiny little corner. Before there was television, people gained their view of the outside world by news-reels, which were run ahead of movies. If a picture is worth a thousand words, how much is a moving picture worth with sound? Our tiny little corners have greatly expanded, thus the causes for our hearts to change have changed as well.
