In the event of examining the nature of Hamlet's madness,we will need to probe into Hamlet's state of mind at different periods and circumstances in the play.
             Hamlet can be seen to be and not to be mad by different people at different stages. From one perspective, Hamlet can be seen to be mad when Ophelia goes to her father and gives a description of Hamlet's disposition when he goes to see her, also when he goes to see his mother in her closet as can be seen in his tone of voice and his murder of Polonius and his lack of repentance for his death. also, his psychological trauma and emotional depression at the begining of the play may have plunged him into emotional insanity, and lastly his encounter with Leartes in Ophelia's grave.
             Reversly, evidence is also shown to prove Hamlet's sanitysuch as, when he initially tell Horatio about his intended change of disposition, also, when he tells both Rosencrantz and Guildestern that he is not mad. Also the things which he claimed to have done on the ship bound for England goes to show his sanity, and lastly his encounter with Leartes in Ophelia's grave.
             Upon the revelation of the ghost who is supposedly Hamlet's father's spirit, we witness a marked change in Hamlet's disposition both in words and in deeds, one of such can be seen when (in Act 2 scene 1) Ophelia goes to see her father, apparently scared gives him a brief but vivid description of Hamlet's disposition when he came to see her. she describes him as having "a look so pietous in purport" as if he had "been loosed out of hell". This shows us a marked change in Hamlet's disposition, the statement "As if he had been loosed out of hell" raises a lot of questions such as, what happened to Hamlet?.
             Possibly,some spirit or demon may have taken over him thus his appearance as being "hellish" in nature or it could be that he had lost his wits to hell and thus is not aware of his appearance and we are made to believe that that he appear...
