"If one abuses or neglects internal powers, external forces will act accordingly. This quote illustrates the concept of both internal and external forces working hand in hand to produce an outcome. The play Macbeth, Shakespeare depicts the similar idea that both internal and external forces lead to Macbeth's downfall. This idea can be illustrated through Macbeth's fearful nature, Lady Macbeth's manipulation, and the three witches' predictions. To begin with, an internal force which vastly contributes to Macbeth's downfall is his fearful and paranoid nature. Macbeth is in constant fear of losing the crown. His insecurities lead him to make decisions a rational, confident person would not. Macbeth's fear is demonstrated after a conversation with Banquo. Banquo has suspicions regarding Macbeth's inheritance of the crown. He raises the suggestion that Macbeth did not obtain the crown fairly. This discussion causes Macbeth to fear Banquo and his abilities. Once Macbeth is unaccompanied, he expresses his fears in Banquo, saying: To be thus is nothing, But to be safely thus. Our fears in Banquo Stick deep; and in his royalty of nature Reigns that which would be fear'd. 'Tis much he dares; And, to that dauntless temper of his mind, He hath a wisdom that doth guide his valour To act in safety. There is none but he Whose being I do fear: [.] then prophet-like They hail'd him father to a line of kings: (Pg 115).
Within this quote, Macbeth speaks of Banquo's noble qualities. Macbeth clearly states his paranoia and feelings of unsafety. He is fearful of Banquo's sons and grandsons, which the witches predicted will be future kings of Scotland. Macbeth's insecurities and fearful nature cause him to be constantly apprehensive, which leads to irrational decisions. Macbeth has no remorse as long as he maintains his position as king. As a result, Macbeth endures a dreadful downfall. Another example of Macbeth's fear is revealed in the banquet scene.
