Things Change

                 "Fair is foul and foul is fair; hover through the fog and filthy air."

             
                  Eveything in this world changes. Nothing is permanent, well except for change. This was one inferred in one of the lines in Shakespeare's Macbeth "Fair is foul and foul is fair". This was said in the end of Act 1 Scene 1 by the three evil witches.

                 What did the witches mean? From fair is foul and foul is fair, it can be inferred that the good things (fair) will turn into ugly things (foul) or foul things would turn into better. Changes, no matter what the circumstances are, will still happen, even if it would be for the better or for the worse. Just like Macbeth, who would expect that a man as noble as him would be resorting to evil deeds?

                 It could also mean that the beautiful things hide an ugly meaning. One of the examples is Macbeth. That's being pretentious. They tend to show different personalities to others, if not, sometimes, the impressions of people for them are different than what they really are. They hide "foul deeds" under their "kind acts".

                 It could also show two different outlooks. The three witches know that their plans, their prophecies, will just cause bad happenings. But even so, Macbeth still flamed the bait. In the point of view of the witches, their plan was really bad but in Macbeth's point of view, it was beautiful for him.

                  All in all, that line set the tragedy of Macbeth. It foreshadowed the evil deeds that Macbeth would do in the play. To be a king in expense of the lives of Duncan and his chamberlains is one. He even ordered to kill Banquo and Fleance, and Macduff's family. The tragedy would have never happened without Macbeth doing what was said in the line. From a fair noble leader to an ugly foul tyrant.
