How can I discuss theme of wisdom in madness and madness in wisdom in "King Lear"?

There is wisdom in madness. King Lear has finally become
wise in his later state in life. He is losing his mind, but finding his wisdom. He
realizes that life is not about appearances. He has learned that the hard
way.

To explain the quote, there is wisdom in madness. King
Lear has learned what is important in life. By learning how superficial his two older
daughters are, it is enough to drive one mad. Learning the truth about his daughters has
literally driven King Lear mad. That explains the quote that there is madness in wisdom.
Learning the truth about his daughters drives King Lear over the edge. He gains wisdom
but loses his mind. One could say he finally finds his mind, but is losing his sanity.
That is one way to deal with the harsh reality of the
truth.

Learning the truth is often so disturbing. The only
way to deal with it is to become mad. It is often so shocking to face the truth until it
leaves one in total disarray. The quote is true. There is wisdom in madness and madness
in wisdom.

Learning that his two daughters have never
really loved him is a bit of wisdom that Ling Lear could have lived without knowing.
Nonetheless, he does know the truth. Now, he is driven to madness in knowing the tragic
truth.

The only way King Lear can survive the horrible
truth he has learned is to totally lose his mind. There is madness in wisdom.
