Alienation: Much Madness

"Much Madness is divinest Sense"
Emily Dickinson

As it states in the question following the poem, the poem presents the ideas that insanity is good sense and good sense is insane. I think the best way to attack this poem is by relating it to real life. How is insanity good sense? Well perhaps if we look at a person such as Albert Einstein, he was crazy, but he was also one of the world's smartest people during his time. There is a good sense within insanity that comes out through craziness. How is good sense insane? Well by good sense people perform an action such as locking a door, then by performing this act so many times the act becomes a habit. When something becomes a habit, the person no longer realizes their reasoning for performing the act which is insane. So you think I am stretching this a little bit? I probably would too, but it made sense in my head.
Question number two asks how we know the speaker does not believe the majority is correct. In the poem the speaker says, "Demur-you're straightway dangerous-/And handled with a Chain-" (Dickinson, 830). This statement provides evidence the the speaker knew what would happen if they disagreed, which allows the reader to know that the speaker does in fact disagree. The last five lines of the poem relate more to going with or away from the majority of people, rather than the subject of insanity and good sense.
