What good essay topics are there for King Lear?

I posted this to a different GradeSaver question but in case you're only checking here, it's repeated below. Any of these are potential questions, but additionally, use them to brainstorm yourself. Even if, say, slight/blindness isn't a question, something about the lack of self-knowledge (which is tied to the theme) will at least touch on one of the questions. Hope this helps.

There are a ton. If your teacher talked at all about sight/blindness, then that will surely be one (exploring the use of imagery and knowledge). A question about duty - duty to parents, to friends, to rulers - is also possible. That is, discussing, the various breaches of duty and what pain they cause. Talking about wisdom vs. foolishness is another good possibility - consider the wise Lear's folly at the beginning vs. the wisdom of his fool.
