In Shakespeare's, King Lear, the Fool plays three major roles. One of these roles is of an "inner-conscience" of Lear. The Fool provides basic wisdom and reasoning for the King at much needed times. The Fool also works as amusement for Lear in times of sadness and is also one of the only people besides the Duke of Kent and Cordelia who are willing to stand up to the King. The Fool works as the "inner conscience" of Lear throughout the play. The Fool shows Lear the side of reasoning and tries to persuade Lear that it was wrong to...
concern and compassion towards the Fool, "Come on, my boy. How dost my boy, art thou cold?"

The Fool is not just a servant to Lear but is also a friend and the son Lear never had. The name "Fool" means nothing. He is the most intelligent and insightful character in the play and provides simple and clear reasoning for a one sighted King. The Fool is loyal to the bitter end and provides the little bits of humour in this play. He has honesty and integrity that is only found in a few other characters in the play.
