Now I am come to mention _Hamlet's_ Madness, I must speak my Opinion of our Poet's Conduct in this Particular. To conform to the Ground-work of his Plot, _Shakespeare_ makes the young Prince feign himself mad. I cannot but think this to be injudicious; for so far from Securing himself from any Violence which fear'd from the Usurper, which was his Design in so doing, it seems to have been the most likely Way of getting himself confin'd, and consequently, debarr'd from an Opportunity of Revenging his Father's Death, which now seem'd to be his only Aim; and accordingly it was the Occasion of his being sent away to _England_. Which Design, had it taken effect upon his Life, he never could have revenged his Father's Murder. To speak Truth, our Poet, by keeping too close to the Ground-work of his Plot, has fallen into an Absurdity; for there appears no Reason at all in Nature, why the young Prince did not put the Usurper to Death as soon as possible, especially as _Hamlet_ is represented as a Youth so brave, and so careless of his own Life.
