When Macbeth sees the Witches again, after the murders of Duncan and Banquo, we observe, however, a striking change. They no longer need to go and meet him; he seeks them out. He has committed himself to his course of evil. Now accordingly they do 'solicit.' They prophesy, but they also give advice: they bid him be bloody, bold, and secure. We have no hope that he will reject their advice; but so far are they from having, even now, any power to compel him to accept it, that they make careful preparations to deceive him into doing so. And, almost as though to intimate how entirely the responsibility for his deeds still lies with Macbeth, Shakespeare makes his first act after this interview one for which his tempters gave him not a hint--the slaughter of Macduff's wife and children. To all this we must add that Macbeth himself nowhere betrays a suspicion that his action is, or has been, thrust on him by an external power. He curses the Witches for deceiving him, but he never attempts to shift to them the burden of his guilt. Neither has Shakespeare placed in the mouth of any other character in this play such fatalistic expressions as may be found in _King Lear_ and occasionally elsewhere. He appears actually to have taken pains to make the natural psychological genesis of Macbeth's crimes perfectly clear, and it was a most unfortunate notion of Schlegel's that the Witches were required because natural agencies would have seemed too weak to drive such a man as Macbeth to his first murder.
