Here is the biggest change that occurs between the quarto and the folio and this section. In the quarto, Shakespeare has this mock trial of his daughters, which is included in the quarto, but not in the folio. The Norton edition says that the lack of this scene in the folio is an act of censorship, as this scene takes away the seriousness of the play before Gloucester's torture scene. However, the editors of the Norton say that they include it because it became an important part of the popular perception of the play. This section is another excellent indicator of Lear's madness, and provides levity in a play that is not exactly known for its humor.
