Hamlet’s reaction to his father’s ghost reveals his determination but also his uncertainty. As Horatio and Marcello hold him back, Hamlet demands that they “hold off [their] hands” (Shakespeare 25). When he first encounters the ghost, he shows no fear, claiming that “a thing immortal as itself” cannot harm him (Shakespeare 24). As Horatio warns him, however, Hamlet becomes less sure of himself. He is struck by the idea that the ghost may mean him harm, that it may “draw [him] into madness” (Shakespeare 25). With this realization, Hamlet is halted in his pursuit of the ghost. He is afraid of the possibilities that lie before him, but his courage prevails. Hamlet decides to follow the ghost, his body as “hardy as the Nemean lion’s nerve” (Shakespeare 25). Hamlet, although careful, is both brave and curious, ignoring his fear in order to move forward.
