It is inadequate here chiefly because it is much too narrow.  The Witches and their prophecies, if they are to be rationalised or taken symbolically, must represent not only the evil slumbering in the hero’s soul, but all those obscurer influences of the evil around him in the world which aid his own ambition and the incitements of his wife.  Such influences, even if we put aside all belief in evil ‘spirits,’ are as certain, momentous, and terrifying facts as the presence of inchoate evil in the soul itself; and if we exclude all reference to these facts from our idea of the Witches, it will be greatly impoverished and will certainly fail to correspond with the imaginative effect.  The union of the outward and inward here may be compared with something of the same kind in Greek poetry.[210] In the first Book of the Iliad we are told that, when Agamemnon threatened to take Briseis from Achilles, ’grief came upon Peleus’ son, and his heart within his shaggy breast was divided in counsel, whether to draw his keen blade from his thigh and set the company aside and so slay Atreides, or to assuage his anger and curb his soul.  While yet he doubted thereof in heart and soul, and was drawing his great sword from his sheath, Athene came to him from heaven, sent forth of the white-armed goddess Hera, whose heart loved both alike and had care for them.  She stood behind Peleus’ son and caught him by his golden hair, to him only visible, and of the rest no man beheld her.’  And at her bidding he mastered his wrath, ’and stayed his heavy hand on the silver hilt, and thrust the great sword back into the sheath, and was not disobedient to the saying of Athene.’[211] The succour of the goddess here only strengthens an inward movement in the mind of Achilles, but we should lose something besides a poetic effect if for that reason we struck her out of the account.  We should lose the idea that the inward powers of the soul answer in their essence to vaster powers without, which support them and assure the effect of their exertion.  So it is in Macbeth.[212] The words of the Witches are fatal to the hero only because there is in him something which leaps into light at the sound of them; but they are at the same time the witness of forces which never cease to work in the world around him, and, on the instant of his surrender to them, entangle him inextricably in the web of Fate.  If the inward connection is once realised (and Shakespeare has left us no excuse for missing it), we need not fear, and indeed shall scarcely be able, to exaggerate the effect of the Witch-scenes in heightening and deepening the sense of fear, horror, and mystery which pervades the atmosphere of the tragedy.
