O good Horatio, I'll take the ghost's word for a thousand pound. Didst perceive?
Act III, Scene 2 · Hamlet
Context
Alone with Horatio after Claudius has fled, Hamlet exults that the Ghost was telling the truth and he would bet a thousand pounds on it, asking if Horatio noticed the King's reaction.
Analysis
Hamlet's willingness to 'take the ghost's word for a thousand pound'—an enormous sum—reveals how desperately he needed Claudius's reaction to resolve his doubt. The colloquial wager contrasts with the metaphysical stakes, as if Hamlet is trying to make supernatural testimony feel as solid as money. Yet even now he needs Horatio's confirmation ('Didst perceive?'), suggesting that witnessing alone is not enough—truth requires corroboration, making revenge a social rather than solitary act.
Essay Tip
Support a thesis that Hamlet cannot act on private knowledge—he needs Horatio as a witness to make Claudius's guilt real, revealing that revenge requires public proof, not just personal certainty.
