Societal Norms

While discussing "The Notes From The Underground" we brought up a discussion about the narrators sanity. While I was looking at him, the things he did, the things he said/ thought, I noticed I could compare him to people I have seen in my everyday life. I work in the Mental Health Services at St. Francis Hospital, so I see people that society may deem, "crazy". I see in this man many issues I would see with a patient, yet do we call him insane? Honestly I have no answer for this question, yet when we look at society we can see that it abuses such stigmas as crazy and insane. Society uses these stigmas as a way to classify those who's minds may be sick or may not think the way that the rest of it does. Yet, these people still have logical purpose, as we can see with the narrator, and still have emotion, and in some cases reason. So really, have we fallen into common misconceptions of society calling someone insane?
