"When shall we three meet again
In thunder, lightening or in rain?
When the Hurlyburly's done,
When the battle's lost and won.
That will be ere the set of sun.
Where the place?
Upon the heath.
There to meet with MacBeth.
I come, Graymalkin!
Fair is foul, and foul is fair: hover through
the fog and filthy air" I, i, 1-12.
The witches are speaking of how fair things are foul to them, for only foul things appeal to witches. Good deeds,
such as telling MacBeth that he will be king, can turn out to be a very evil thing, for he could try to persue this dream
causing only pain and termoil. A paradox was used to symbolize that maybe the witches are crazy, but in the end, we
know that they really arn't.
