'Still,' it may be said, 'the Witches did foreknow Macbeth's future; and what is foreknown is fixed; and how can a man be responsible when his future is fixed?' With this question, as a speculative one, we have no concern here; but, in so far as it relates to the play, I answer, first, that not one of the things foreknown is an action. This is just as true of the later prophecies as of the first. That Macbeth will be harmed by none of woman born, and will never be vanquished till Birnam Wood shall come against him, involves (so far as we are informed) no action of his. It may be doubted, indeed, whether Shakespeare would have introduced prophecies of Macbeth's deeds, even if it had been convenient to do so; he would probably have felt that to do so would interfere with the interest of the inward struggle and suffering. And, in the second place, _Macbeth_ was not written for students of metaphysics or theology, but for people at large; and, however it may be with prophecies of actions, prophecies of mere events do not suggest to people at large any sort of difficulty about responsibility. Many people, perhaps most, habitually think of their 'future' as something fixed, and of themselves as 'free.' The Witches nowadays take a room in Bond Street and charge a guinea; and when the victim enters they hail him the possessor of L1000 a year, or prophesy to him of journeys, wives, and children. But though he is struck dumb by their prescience, it does not even cross his mind that he is going to lose his glorious 'freedom'--not though journeys and marriages imply much more agency on his part than anything foretold to Macbeth. This whole difficulty is undramatic; and I may add that Shakespeare nowhere shows, like Chaucer, any interest in speculative problems concerning foreknowledge, predestination and freedom. (2) We may deal more briefly with the opposite interpretation. According to it the Witches and their prophecies are to be taken merely as symbolical representations of thoughts and desires which have slumbered in Macbeth's breast and now rise into consciousness and confront him. With this idea, which springs from the wish to get rid of a mere external supernaturalism, and to find a psychological and spiritual meaning in that which the groundlings probably received as hard facts, one may feel sympathy. But it is evident that it is rather a 'philosophy' of the Witches than an immediate dramatic apprehension of them; and even so it will be found both incomplete and, in other respects, inadequate.
