It is interesting that, in the quarto version, the fool says "Here's a night pities neither wise man nor fool," while, in the folio version, the fool's sentence becomes plural: "Here's a night pities neither wise men, nor fools." When the sentence says "wise man nor fool," it seems that the fool implies that, of Lear and himself, one is a wise man and one is a fool--even though which character is the wise man or fool is not specified. When the sentence says "wise men, nor fools," it seems that the fool implies that, of Lear and himself, one could be wise, one a fool, or both characters could be wise men or fools. The situation seems a bit more vague. The answer to this question of characterization as wise or foolish is never explicitly answered in the quarto and folio versions of the play.
