The doctrine or the motive of chance (whichever we may prefer to call it) is seen in its fullest workings and felt in its furthest bearings by the student of Webster's masterpiece. The fifth act of "The Duchess of Malfy" has been assailed on the very ground which it should have been evident to a thoughtful and capable reader that the writer must have intended to take up--on the ground that the whole upshot of the story is dominated by sheer chance, arranged by mere error, and guided by pure accident. No formal scheme or religious principle of retribution would have been so strangely or so thoroughly in keeping with the whole scheme and principle of the tragedy. After the overwhelming terrors and the overpowering beauties of that unique and marvellous fourth act, in which the genius of this poet spreads its fullest and its darkest wing for the longest and the strongest of its flights, it could not but be that the subsequent action and passion of the drama should appear by comparison unimpressive or ineffectual; but all the effect or impression possible of attainment under the inevitable burden of this difficulty is achieved by natural and simple and straightforward means. If Webster has not made the part of Antonio dramatically striking and attractive--as he probably found it impossible to do--he has at least bestowed on the fugitive and unconscious widower of his murdered heroine a pensive and manly grace of deliberate resignation which is not without pathetic as well as poetical effect. In the beautiful and well-known scene where the echo from his wife's unknown and new-made grave seems to respond to his meditative mockery and forewarn him of his impending death, Webster has given such reality and seriousness to an old commonplace of contemporary fancy or previous fashion in poetry that we are fain to forget the fantastic side of the conception and see only the tragic aspect of its meaning. A weightier objection than any which can be brought against the conduct of the play might be suggested to the minds of some readers--and these, perhaps, not too exacting or too captious readers--by the sudden vehemence of transformation which in the great preceding act seems to fall like fire from heaven upon the two chief criminals who figure on the stage of murder. It seems rather a miraculous retribution, a judicial violation of the laws of nature, than a reasonably credible consequence or evolution of those laws, which strikes Ferdinand with madness and Bosola with repentance. But the whole atmosphere of the action is so charged with thunder that this double and simultaneous shock of moral electricity rather thrills us with admiration and faith than chills us with repulsion or distrust. The passionate intensity and moral ardor of imagination which we feel to vibrate and penetrate through every turn and every phrase of the dialogue would suffice to enforce upon our belief a more nearly incredible revolution of nature or revulsion of the soul.
