Response to the Lecture on Self Delusion

          Delusion has many, if not infinite, sub-genres. Self delusion happens to be the topic of another influential lecture, in my eyes. Regarding the incident that happened to Blanche in the play A Streetcar Named Desire, Blanche is in a deluded state that she isn't poor, and that she is wanted by men, and that she has a line going down the block of men that want a chance to date her. 

          While Blanche is depicted as attractive, she is aging, and out of her prime, and hardly has any man going after her. However, in an attempt to make herself happy, she makes up the story that she is wanted and loved by all men, until Stanley comes and ruins that image she has of herself because he, himself, is insecure of his failing marriage and severe anger issues. Is self delusion necessary in order to keep some sanity? Is it needed for happiness?
