(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 ( 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).

(d) The quarrel-scene illustrates yet another favourite expedient.

So it is
