The pictures come quickly upon the screen of the mind. How readily they are summoned by suggestion! If I had time I could bore you almost to extinction by calling up in your minds images that are common to all of us. We all have large collections of slides. The depressing fact is that for the most part they are identical. How refreshing it is to meet an original person. Who is the original person? Just the person that has some slides that were made at home. Most of us have the same old, tiresome slides. When we have to make conversation, what do we do? Go to the pigeon-hole, take out a slide, put it into our minds and then reflect it to our friends. We have to be able to talk on a great variety of subjects. In the nature of things we could not think out these things for ourselves. Society has provided the slides. There they are, like a well-organized collection, a card catalog, with a topical index. To suppose that we make the slides ourselves is a grateful illusion. There may be a few who do, but most of us get ours from the stock houses in New York and Chicago. Was there ever a time when pictorial imagery was presented to the public as in these days? These are the days when people's minds are filled with visual imagery as never before in the history of mankind. And never before was the same imagery spread over so wide an area. Think, for example, of what cartoons do. Cartoons are a substitute for thinking. Cartoons are ready-made slides. Cartoons are arguments ready to serve. Cartoons demand no intellectual effort. They would not be successful as cartoons if they did. A cartoon which you have to analyze is in the nature of things a mistake and a disappointment. A cartoon tells the story instantly. It is a slide put into the minds of millions of people in a single week. Then consider the imagery sent out by the illustrated magazines. There is only one magazine, I think, now, that does not have illustrations. Some of us take it just for that reason. It has a kind of distinction on that account. The _Atlantic Monthly_ has no illustrations except in the advertising pages--some of those are very good--but it has that sense of uniqueness, that kind of snobbishness, which is appreciated even in a democracy like our glorious democracy, where we are all free and equal, as contrasted with the social distinctions of this monarchy under which we are so hospitably received this evening. It is a mistake to suppose that the visual is suggested merely by drawings and photographs. When we go to a lecture on "Mother, Home and Heaven" we expect the speaker in lieu of lantern slides to supply "word pictures." The Sunday supplement is the absolute symbol of our state of mind.
