Madness is a condition that is difficult to distinguish between true and false. As with Hamlet's encounter with the ghost of Hamlet's father, Hamlet is asked to avenge his father's death. To accomplish this task in a less apparent way, Hamlet decides to feign madness. In the long run, Hamlet really goes mad. As a result, his behavior afterwards is often unfathomable. William Shakespeare, the author of the tragic play Hamlet, leaves Hamlet's sanity up to interpretation. Throughout Shakespeare's Hamlet, Hamlet's questionable madness is explored through his actual madness, his feigned actions, and the reactions of others to his madness. In some cases, Hamlet's madness can be considered genuine. When Hamlet once hacks Polonius to inform Ophelia, his daughter, of Hamlet's madness, Polonius goes straight to King Claudius and reveals that he has the reason for Hamlet's madness. Gertrude replies: “I only doubt the main thing, the death of her father and our hasty marriage” (Shakespeare 2.2 56-57). As Hamlet's mother, wife of Hamlet's father, and wife of Hamlet's father's brother, Gertrude is blind to any other reason other than the death of Hamlet's father and his rapid remarriage. However, Polonius believes differently and tells Claudius how Ophelia obeyed his advice to "lock herself out of her complex, / Admit no messenger, receive no sign...in the madness in which now [Hamlet] s 'ecstasy' (Shakespeare 2.2. 142-149). . Polonius speculates that Hamlet's disillusioned love for Ophelia is the cause of his madness. Since no one knows Hamlet's true inspiration, everyone's opinion of his madness is biased. Gertrude bases her reasoning on Hamlet's experience following the death of his father and his fault in his quick marriage to his son's uncle. On the other hand, Polonius bases his reason on his knowledge and interference in the relationship between his daughter and Hamlet. At first glance, Hamlet's madness is seen as innocent and seems to stem from the problems already present. However, with Hamlet's murder of Polonius, his madness takes on a different meaning. When Gertrude speaks about it to Claudius, Shakespeare lets his audience create their own perception by only serving minor stagings. They are then left with Hamlet's words, actions, and persistent reactions to find out whether Hamlet's madness is truly feigned or legitimate. However, the evidence does not actually define Shakespeare's character Hamlet. To understand, modern audiences must do their research to become accustomed to the way of thinking of Renaissance people. Overall, the true strength of Hamlet is left to the discretion of people today.
