Cordelia loves Lear according to the bonds of a blood relationship, as paternity demands. Her response is in keeping with Elizabethan social norms, which expect a daughter to love her father because that is the law of nature. According to nature, man is part of a hierarchy, from God to king to father to child. The love between each of these parties is reciprocal, and Cordelia's love for her father is what she owes him.
Cordelia tempers her love test reply with reason — a simple, unembellished statement of the honor due a father from his daughter. Lear irrationally responds by denying Cordelia all affection and paternal care.
Kent's interference on Cordelia's behalf leads to another outburst from Lear. Like Cordelia, Kent is honest with the king, providing a voice of reason. Kent sees Lear making a mistake and tells him so. The depth of Lear's anger toward Kent suggests excessive pride — Lear cannot be wrong. Cordelia's answer injures Lear's pride; he needs her excessive protestations of love to justify giving her the choicer parcel of land. Lear's intense anger toward Kent also suggests the fragility of the king's emotional state.
Cordelia's two suitors provide more drama in this initial scene. The Duke of Burgundy cannot love Cordelia without her dowry, but the King of France points out that she is a prize as great as any dowry and correctly recognizes that Burgundy is guilty of selfish self-interest. France's reply to Cordelia reveals that he is, indeed, worthy of Cordelia's love:
Fairest Cordelia, that art most rich, being poor,
Most choice, forsaken, and most lov'd, despis'd!
Thee and thy virtues here I seize upon,
Be it lawful I take up what's cast away. (I.1.249–252)
