The fact that dramatic action is mock action and mimetic art completely gratuitous makes the dramatic picture of human life a peculiar one. In real life, we exist as bodies, social individuals and unique persons simultaneously, so that there can be no human deed or act of personal choice which is without an element of human behavior, what we do from necessity, either the necessities of our physical nature or the habits of our socially acquired "second nature." But on the stage, the kind of human life we see is a life of pure deeds from which- every trace of behavior has been eliminated. Consequently, any human activity which cannot be imagined without its element of necessity, cannot be represented on the stage. Actors, for example, can toy with cucumber sandwiches, but they cannot eat a hearty meal because a hearty meal cannot be imagined taking less than three quarters of an hour to consume. Dramatists have been known to expect an actor to write a letter on stage, but it always looks ridiculous; on stage a letter can be read aloud but not written in silence. Nor can an actor do any serious piece of work, for real work cannot be imagined apart from the real time it takes. Only deeds can be divorced from real time. Thus, a man might write in his diary, "I began or I finished work at 9:15," but he would never write "I worked at 9:15"; (as a court witness he might say, "I was working at 9:15"); on the other hand, he might very well write, "At 9:15 I proposed to Julia and she accepted me" because, although his words of proposal and hers of acceptance must have taken a certain length of time to utter, this is irrelevant to the dramatic significance of the event.
Since human life, as the stage can present it, is, firstly, a life of pure action and, secondly, a public life—the actors play to an audience, not to themselves—the characters best-suited to drama are men and women who by fate or choice lead a public existence and whose deeds are of public concern. Worldly ambition, for example, is a more dramatic motive than sexual passion, because worldly ambition can only be realized in public, while sexual passion unless, like that of Antony and Cleopatra, it has political consequences, affects only a handful of persons. Unfortunately for the modern dramatist, during the past century and a half the public realm has been less and less of a realm where human deeds are done, and more and more a realm of mere human behavior. The contemporary dramatist has lost his natural subject.
This process was already far advanced in the nineteenth century and dramatists, like Ibsen, who took their art seriously, were beginning to look for new kinds of heroes. The romantic movement had brought to public notice a new kind of hero, the artist-genius. The public interest taken in figures like Victor Hugo, Dickens and Wagner would have been unthinkable two centuries earlier.
It was inevitable that, sooner or later, a dramatist would ask himself if the artist-genius could be substituted for the traditional man-of-action as a dramatic hero. A sensible dramatist, however, would immediately realize that a direct treatment would be bound to fail. An artist is not a doer of deeds but a maker of things, a worker, and work cannot be represented on stage because it ceases to be work if the time it takes is foreshortened, so that what makes an artist of interest, his art—aside from which he is not an artist but simply a man—will have to take place off stage. Secondly, the audience will have to be convinced that the figure they are told is a genius really is one, not somebody without any talent who says he is a genius. If he is a poet, for example, the poetry of his which the audience hear must be of the first order. But, even if the dramatist is himself a great poet, the only kind of poetry he can write is his own; he cannot make up a special kind of poetry for his hero, unlike his own yet equally great. Lastly, while deeds and character are identical, works and character are not; the relation between who an artist is as a person and what he makes is too vague to discuss. To say that Lesbia's treatment of Catullus and his love for her were the cause of his poetry is a very different thing from saying that Macbeth's ambition and the prophecies of the witches were the cause of Banquo's murder. Had both their characters been different, the poems would, no doubt, have been different, but their characters do not explain why Catullus wrote the actual poems he did, and not an infinite number of others which he might equally well have written but did not.
