Paradoxical Madness

In Much Madness is divinest Sense by Emily Dickinson, the speaker uses a paradox to form an aphorism: "Much madness is divinest Sense-- To a discerning Eye--" (Dickinson, 830). It seems that being insane can be rational, depending on how we see it. The majority of opinion seems to decide what is sane and insane. The paradox points out this hidden truth. We all have our individual opinions on what is sane and insane, but we don't get to decide. Society decides what is sane and insane. If we agree with society, we are sane. If there is a discrepancy  the person with the difference is labeled as an outcast and insane. Even if the majority happens to be incorrect, the outcast is still treated harshly. Additionally, society aims to control those outcasts and maniacs by reducing their freedom and sometimes oppressing them. Their hope is that they will conform their views and agree with society.
