below the surface, there is evidence enough in the earlier scenes of preparation for the later. I do not mean that Lady Macbeth was naturally humane. There is nothing in the play to show this, and several passages subsequent to the murder-scene supply proof to the contrary. One is that where she exclaims, on being informed of Duncan’s murder,
What, in our house?
This mistake in acting shows that she does not even know what the natural feeling in such circumstances would be; and Banquo’s curt answer, ‘Too cruel anywhere,’ is almost a reproof of her insensibility. But, admitting this, we have in the first place to remember, in imagining the opening scenes, that she is deliberately bent on counteracting the ‘human kindness’ of her husband, and also that she is evidently not merely inflexibly determined but in a condition of abnormal excitability. That exaltation in the project which is so entirely lacking in Macbeth is strongly marked in her. When she tries to help him by representing their enterprise as heroic, she is deceiving herself as much as him. Their attainment of the crown presents itself to her, perhaps has long presented itself, as something so glorious, and she has fixed her will upon it so completely, that for the time she sees the enterprise in no other light than that of its greatness. When she soliloquises,
It is too full o’ the milk of human kindness
To catch the nearest way: thou wouldst be great;
Art not without ambition, but without
The illness should attend it; what thou wouldst highly,
That wouldst thou holily,
one sees that ‘ambition’ and ‘great’ and ‘highly’ and even ‘illness’ are to her simply terms of praise,
