But the mere interest springing from words cannot in the least explain that constantly shifting action of our involuntary attention during a theater performance.

The movements of the actors are essential.
The pantomime without words can take the place of the drama and still appeal to us with overwhelming power.

The actor who comes to the foreground of the stage is at once in the foreground of our consciousness.

He who lifts his arm while the others stand quiet has gained our attention.

Above all, every gesture, every play of the features, brings order and rhythm into the manifoldness of the impressions and organizes them for our mind.
