The fear that a foreign king might weaken England (and a Catholic monarch made it worse) would have made Lear's actions seem even more irresponsible to the audience. But Lear is doing more than creating political and social chaos; he is also giving his daughters complete responsibility for his happiness, and he will blame them later when he is not happy.
Moreover, the test that Lear devises to measure his daughters' love is a huge mistake. Lear is depicted as a wise ruler — he has, after all, held the country together successfully for many years. Yet he lacks the common sense or the ability to detect his older daughters' falseness. This flaw in Lear leads the audience to think him either mad or stupid.
The love test is derived from Shakespeare's source and so it is included. Shakespeare's primary source is an anonymous play, The True Chronicle History of King Leir, in which the love test is used to trick Cordelia into marriage. Consequently, the test of love is only a device to further the plot, which Shakespeare plucked from his source. It is important to remember that King Lear is not historically based, although sources state that the story was based on events occurring at about 800 B.C. King Lear should more accurately be regarded as a sort of fairy tale. In many ways, Goneril and Regan are similar to Cinderella's evil older sisters.
Goneril and Regan's expressions of love are so extreme that they are questionable as rational responses to Lear's test. Cordelia's reply is honest, but Lear cannot recognize honesty amid the flattery, which he craves. Of course, Lear is not being honest either when he asks Cordelia, "what can you say to draw / A third more opulent than your sisters?" (I.1.84–85). Lear plans to reward Cordelia's expected exaltation with a larger portion of his kingdom than that allotted to her sisters. The shares should be equal, but Lear clearly loves Cordelia more. Cordelia's reply, "Nothing," is a word that will reappear throughout the play — with disastrous connotations. "Nothing" is a key word that is repeated several times in the play, thus emphasizing the word's importance. Cordelia's uttering of "nothing" is echoed at the end of the play when she is dead, and "nothing" remains of her. But it is also important to remember that Lear really understands "nothing" about his daughters, just as Gloucester knows "nothing" about his sons. When Gloucester sees "nothing," he is finally able to see the truth, and when Lear emerges from the "nothingness" of his mental decline, it is to finally know that Cordelia has always loved him.
