If this is the outcome of esthetic analysis on the one side, of psychological research on the other, we need only combine the results of both into a unified principle:  the photoplay tells us the human story by overcoming the forms of the outer world, namely, space, time, and causality, and by adjusting the events to the forms of the inner world, namely, attention, memory, imagination, and emotion.

We shall gain our orientation most directly if once more, under this point of view, we compare the photoplay with the performance on the theater stage.  We shall not enter into a discussion of the character of the regular theater and its drama.  We take this for granted.  Everybody knows that highest art form which the Greeks created and which from Greece has spread over Asia, Europe, and America.  In tragedy and in comedy from ancient times to Ibsen, Rostand, Hauptmann, and Shaw we recognize one common purpose and one common form for which no further commentary is needed.  How does the photoplay differ from a theater performance?  We insisted that every work of art must be somehow separated from our sphere of practical interests.  The theater is no exception.  The structure of the theater itself, the framelike form of the stage, the difference of light between stage and house, the stage setting and costuming, all inhibit in the audience the possibility of taking the action on the stage to be real life.  Stage managers have sometimes tried the experiment of reducing those differences, for instance, keeping the audience also in a fully lighted hall, and they always had to discover how much the dramatic effect was reduced because the feeling of distance from reality was weakened.  The photoplay and the theater in this respect are evidently alike.  The screen too suggests from the very start the complete unreality of the events.

But each further step leads us to remarkable differences between the stage play and the film play.  In every respect the film play is further away from the physical reality than the drama and in every respect this greater distance from the physical world brings it nearer to the mental world.  The stage shows us living men.  It is not the real Romeo and not the real Juliet; and yet the actor and the actress have the ringing voices of true people, breathe like them, have living colors like them, and fill physical space like them.  What is left in the photoplay?  The voice has been stilled:  the photoplay is a dumb show.  Yet we must not forget that this alone is a step away from reality which has often been taken in the midst of the dramatic world.  Whoever knows the history of the theater is aware of the tremendous role which the pantomime has played in the development of mankind.  From the old half-religious pantomimic and suggestive dances out of which the beginnings of the real drama grew to the fully religious pantomimes of medieval ages and, further on, to many silent mimic elements in modern performances, we find a continuity
