Answer:
I disagree with this statement.
Step-by-step explanation:
I believe that even though we live in the 21st century, superstition still plays an important part of our lives, depending on the part of the world you live in. But let's discuss Macbeth first.
In the play itself, Macbeth meets three witches who tell them their prophecy: that he will become king in the future. Here we immediately have superstition - he isn't sure whether or not he should believe them, but when signs start appearing that indicate their prophecy was true, he realizes they were right.
Outside of the play, there is this term 'the Macbeth curse.' It is bad luck to say the word 'Macbeth' in a theater (unless the actors are rehearsing or performing) because it will bring something bad to those involved.
In the contemporary life, there are still traces of superstition. For example, some people avoid passing underneath a ladder; some will retrace their steps if a black cat crosses their path; in some parts of the world, children are given symbolic names in order to 'protect' them from evil, etc.
