Charles Lamb focuses on the major role of Hamlet's internal musings within the play. Throughout the play, the perigrinations of his mind find expression in soliloquies, dialogue and action.

I confess myself utterly unable to appreciate that celebrated soliloquy in Hamlet, beginning 'To be or not to be,' or to tell whether it be good, bad, or indifferent, it has been so handled and pawed about by declamatory boys and men, and torn so inhumanly from its living place and principle of continuity in the play, till it is become to me a perfect dead member.  - Charles Lamb, On the Tragedies of Shakespeare, in Selected Prose, Penguin, London. 1985. p. 47. Why, nine parts in ten of what Hamlet does, are transactions between himself and his moral sense, they are the effusions of his solitary musings, which he retires to holes and corners and the most sequestered parts of the palace to pour forth; or rather, they are the silent meditations with which his bosom is bursting, reduced to words for the sake of the reader, who must else remain ignorant of what is passing there.  - p. 115.
