(_b_) Either at this point, or in the scene of the counter-stroke which precedes it, we sometimes find a peculiar effect. We are reminded of the state of affairs in which the conflict began. The opening of _Julius Caesar_ warned us that, among a people so unstable and so easily led this way or that, the enterprise of Brutus is hopeless; the days of the Republic are done. In the scene of Antony's speech we see this same people again. At the beginning of _Antony and Cleopatra_ the hero is about to leave Cleopatra for Rome. Where the play takes, as it were, a fresh start after the crisis, he leaves Octavia for Egypt. In _Hamlet_, when the counter-stroke succeeds to the crisis, the Ghost, who had appeared in the opening scenes, reappears. Macbeth's action in the first part of the tragedy followed on the prediction of the Witches who promised him the throne. When the action moves forward again after the banquet-scene the Witches appear once more, and make those fresh promises which again drive him forward. This repetition of a first effect produces a fateful feeling. It generally also stimulates expectation as to the new movement about to begin. In _Macbeth_ the scene is, in addition, of the greatest consequence from the purely theatrical point of view. (_c_) It has yet another function. It shows, in Macbeth's furious irritability and purposeless savagery, the internal reaction which accompanies the outward decline of his fortunes. And in other plays also the exhibition of such inner changes forms a means by which interest is sustained in this difficult section of a tragedy. There is no point in _Hamlet_ where we feel more hopeless than that where the hero, having missed his chance, moralises over his irresolution and determines to cherish now only thoughts of blood, and then departs without an effort for England. One purpose, again, of the quarrel-scene between Brutus and Cassius (IV. iii), as also of the appearance of Caesar's ghost just afterwards, is to indicate the inward changes. Otherwise the introduction of this famous and wonderful scene can hardly be defended on strictly dramatic grounds. No one would consent to part with it, and it is invaluable in sustaining interest during the progress of the reaction, but it is an episode, the removal of which would not affect the actual sequence of events (unless we may hold that, but for the emotion caused by the quarrel and reconciliation, Cassius would not have allowed Brutus to overcome his objection to the fatal policy of offering battle at Philippi).
