The concept of monarchy in Macbeth is centered around the idea of divine right, where the monarch is believed to have been chosen by God to rule and is accountable only to God. This concept is exemplified by King Duncan, who is portrayed as a benevolent and just ruler. When he is murdered by Macbeth, the natural order is disrupted, leading to chaos and violence.
The line "There's no art to find the mind's construction in the face" suggests that it is impossible to judge a person's character or intentions based on their physical appearance. This idea challenges the notion of divine right, as it implies that a person's worth and suitability for rule cannot be determined by their outward appearance alone.
In the context of the play, this line highlights the deceptive nature of appearances and the difficulty in discerning a person's true character. It underscores the complexity of human nature and the danger of making assumptions about others based solely on their physical attributes.
Therefore, the line "There's no art to find the mind's construction in the face" does not reflect the concept of monarchy in Macbeth, but rather emphasizes the importance of looking beyond physical appearance to understand a person's true nature.
