I need help in writing a good thesis statement about thy symbolism of light and darkness in Edgar Poe's work.

If your allowed to expand your thesis to Poes mental illness that would be awsome. It help students who domt appreciate Poes writings.He allows us to really look into the anxiety of the mind thru reading. What an awsome tool for Poe to use to get thru the manic phases he himself expierienced. I would lay it out wiyh explanation/example to Murdre In Rue Moruge and enlighten the manic phase that he was trying to articulate. Good luck- Misss Eva
