Indeed, Lear reaches the peak of his insanity in this act, and carries forth a mock trial of Regan and Goneril in act three scene six. This is possibly the most chaotic of all Shakespeare's scenes - onstage we physically see Lear, who is now utterly mad, Edgar who is disguised and likely to be mad, Kent in disguise and Fool who speaks as a madman - Regan and Goneril are arraigned but then, within Lear's diseased imagination, they escape, demonstrating that reality punctures even this, the most surreal of Lear's fantasies to date. The fool's departure from the play at the crest of Lear's madness may suggest that he is now superfluous in the context of a kingdom in which the king is a deranged lunatic. Lear has so many unanswered questions in this scene, he hasn't fully understood why all this has happened to him. If he can find the truth as to why his daughters treated him so cruelly, perhaps he will be able to regain sanity. The king appoints his fool as one of the judges of the trial, where he implores the judges to "anatomize Regan: see what breeds about her heart." Lear's words are so cold and angry that even Fool is unable to make any comment.
