The most important scene inKing Learis Scene 4 of Act 2. This is where Lear confronts both of his ungrateful daughters, Goneril and Regan, and realizes that, rather than loving him as they protested at the beginning of the play, they care nothing about the old man in spite of his having divided his entire kingdom between them. At one point Lear says, "I gave you all--" Regan interrupts him, saying, "And in good time you gave it," implying that he was getting senile and could no longer govern by himself. Both daughters have decided to break their promise to provide for Lear's hundred knights. They will only provide for him, and he realizes he will not receive the respect he is accustomed and entitled to. The cold ingratitude of the daughters drives Lear into a rage. He says, "O fool, I shall go mad." At the end of this scene a terrible storm is brewing, and Lear is left out in the cold, a former king who is now a homeless pauper. This is a long scene. It spells out the king's disillusionment and helplessness and the daughters' wickedness, selfishness, and greed. Lear realizes that one cannot buy love. The storm symbolizes the mixed emotions that are driving him completely mad.
