Laertes's Character is a very odd one; it is not easy to say, whether it is good or bad; but his consenting to the villainous Contrivance of the Usurper's to murder _Hamlet_, (p. 342.) makes him much more a bad Man than a good one. For surely Revenge for such an accidental Murder as was that of his Father's (which from the Queen, it is to be supposed he was acquainted with all the Circumstances of) could never justify him in any treacherous Practices. It is a very nice Conduct in the Poet to make the Usurper build his Scheme upon the generous unsuspicious Temper of the Person he intends to murder, and thus to raise the Prince's Character by the Confession of his Enemy, to make the Villain ten Times more odious from his own Mouth. The Contrivance of the Foil unbated (i.e. without a Button) is methinks too gross a Deceit to go down even with a Man of the most unsuspicious Nature.
