Read the excerpt from Act II of Hamlet. Hamlet: I’ll observe his looks; I’ll tent him to the quick: if he but blench I know my course. The spirit that I have seen May be the devil: and the devil hath power To assume a pleasing shape; yea, and perhaps Out of my weakness and my melancholy— As he is very potent with such spirits— Abuses me to damn me. I’ll have grounds More relative than this: the play’s the thing Wherein I’ll catch the conscience of the king.
