simpler model before we can manage with it. To traverse the world men must have maps of the world. Their persistent difficulty is to secure maps on which their own need, or someone else's need, has not sketched in the coast of Bohemia.

The analyst of public opinion must begin then, by recognizing the triangular relationship between the scene of action, the human picture of that scene, and the human response to that picture working itself out upon the scene of action. It is like a play suggested to the actors by their own experience, in which the plot is transacted in the real lives of the actors, and not merely in their stage parts. The moving picture often emphasizes with great skill this double drama of interior motive and external behavior. Two men are quarreling, ostensibly about some money, but their passion is inexplicable. Then the picture fades out and what one or the other of the two men sees with his mind's eye is reenacted. Across the table they were quarreling about money. In memory they are back in their youth when the girl jilted him for the other man. The exterior drama is explained: the hero is not greedy; the hero is in love.
