It must be remembered, however, that very often these plays are only a third part of the real subject dealt with by the playwright. All Greek tragedy is liable to these criticisms; it is not fair to judge a process just beginning by the standards of an art which thinks itself full-blown after many centuries of history. Considering the meagre resources available for Aeschylus--the masks used by Greek actors made it impossible for any of them to win a reputation or to add to the fame of a play--we ought to admire the marvellous success he achieved. His defects are clear enough; his teaching is a little archaic, his plots are sometimes weak or not fully worked out, his tendency is to description instead of vigorous action, he has a superabundance of choric matter. Sometimes it is said that the doctrine of an inherited curse on which much of his work is written is false; let it be remembered that week by week a commandment is read in our churches which speaks of visiting the sins of the fathers upon the third and fourth generation of them that hate God; all that is needed to make Aeschylus' doctrine "real" in the sense of "modern" is to substitute the nineteenth-century equivalent Heredity. That he has touched on a genuine source of drama will be evident to readers of Ibsen's _Ghosts_. More serious is the objection that his work is not dramatic at all; the actors are not really human beings acting as such, for their wills and their deeds are under the control of Destiny. What then shall we say of this from Hamlet:-- "There's a divinity that shapes our ends, Rough-hew them as we will?" In this matter we are on the threshold of one of our insoluble problems--the freedom of the will. An answer to this real fault in Aeschylus will be found in the subsequent history of the Attic drama attempted in the next two chapters. Suffice it to say that, whether the will is free or not, we act as if it were, and that is enough to represent (as Aeschylus has done) human beings acting on a stage as we ourselves would do in similar circumstances, for the discussions about Destiny are very often to be found in the mouths not of the characters, but of the Chorus, who are onlookers.
