In Shakespeare's Macbeth, one of the reoccurring themes throughout the
             play was "Fair is foul and foul is fair." This is used to explain that people and
             events may seem either good or bad, but after some inspection, turn out to be the
             opposite. In my opinion, "Nothing is but what is not," is similar to "Fair is foul and
             foul is fair," because it is declaring how things are, in fact, what people believe
             First, throughout the play, many people end up being the opposite of how
             their peers actually perceive them. In the play's opening act, the Thane of
             Cawdor is discovered as being a leader of the rebel forces after Duncan had
             previously believed in his loyalty. In act one, the same can also be said for
             Macbeth. As soon as the witches tell Macbeth of his new title and then foretell
             that he will be king, he too begins to turn his once loyal thoughts against the
             beloved king. In addition to Macbeth, his wife is also a good example. She is
             busily making her castle ready for Duncan's visit. When he arrives, he gives her
             gifts and thanks her for being his host, when she was actually planning his
             murder. It is a popular reoccurrence in a number of the Shakespearean plays for
             people to appear to be one thing, but on the inside, to be completely different.
             Not only does this theme apply to people, but it also applies to different
             events during the play as well. There are comments made to how the day is
             "Foul and fair." This simply relates someone's emotions to the weather. They
             could be personally having a terrible day, but the weather outside is simply
             gorgeous. The same was said for Macbeth's castle when Duncan and his
             followers arrived for their visit. Duncan himself commented on how nice the
             castle appeared. Little did he know that it would be the shelter for his demise.
             Next, and possibly the greatest example of "Nothing is but what is not," is
             Macbeth's will to become the kin...
