In the first place, I notice that the behavior of Hamlet, which has the reputation of being feigned, is a genuine exercise of Irony, and consequently covers a feeling and purpose that are directly opposite to its tone of lightness; but it results organically from Hamlet's new experience, and does not require to be premeditated as madness would be. We see his vigorous and subtle mind set open by the revelations of the ghost; but it is too well hung to be slamming to and fro in gusts of real madness, and its normal movement shuts out the need of feigning. When his father first tells that he has been murdered, we find that Hamlet thinks himself quite capable of decision: there is no infirmity of purpose in that early mood to sweep to his revenge "with wings as swift as meditation or the thoughts of love." What is it that converts this mood into an irresoluteness which contrives the whole suspense, and in fact gives us the whole tragedy? First, partly, that his father tells Hamlet he was murdered by his own brother. Then the question of revenge becomes more difficult to settle, especially as it involves widowing his mother; and it is noticeable that the father himself, who afterwards deplored Hamlet's irresolution, had previously made suggestions to him which hampered his action by constraining him to feel how complicated the situation was. The father's caution runs thus:-- "But, howsoever thou pursu'st this act, Taint not thy mind, nor let thy soul contrive Against thy mother aught: leave her to Heaven, And to those thorns that in her bosom lodge, To prick and sting." This does not inhibit Hamlet from dealing retribution on the uncle, but clogs a mind so sensitive with the drawback of consideration for the wife: she is evidently no accomplice or confidant of the murder; that is clear from the uniform respect, and even tenderness, which the ghost craves for her.
