Perhaps I may give you another, more familiar, example, to show you what I mean. In the movie theatres, jokes and funny remarks are often thrown upon the screen. Watch the audience the next time you have a chance. A few people seem almost to inhale the words. It takes them but a second to read the lines. Others are a bit slower. Still others take from twenty to thirty seconds. Finally those men and women who do not read any more than they can help, get the point when the brighter ones among the audience have already begun to decipher the next cut-in. It is not different in human life, as I shall now show you.
