Much Madness in Divinest Sense
What the world considers to be senseless is the excellent knowledge to a wise man. And what the world accepts as sensible is absolutely foolish to a critical person. The majority of the people find wisdom in foolish things, and this idea is popular. If you agree with the majority, you are sane, and if you disagree then you are considered to be the mad and they will imprison you immediately.
The poem says that what the work (a piece of art) considered to be madness is the supreme wisdom to a man of careful judgment and what is the wisdom to many people is completely nonsense to a wise man. The poet persona, expects that it is all a game of majority. If you agree with what the mass, society or the majority says, then you are considering being sane. But if you don’t agree with what the majority says, then you are declared abnormal and dangerous. The result is you will be tied with chains and put into an asylum or prison.
The poem Much Madness is Divinest Sense by Emily Dickinson can be interpreted as a strong voice of protest against the system that follows the rules of majority even it is wrong and disregards the minority even if it is right. But for Dickinson it is the truth that is more important than the number of people for or against it. The poem is a strong voice of individuality and personal freedom. Dickinson despises (dislikes) the life of the frogs that croak in the same tone without understanding what the sound really means. The poet expresses her anger towards the society for curtailing (limiting) the right and freedom of an individual. She is clearly unhappy with the system in which you have to except even something fundamentally illogical simply because that is accepted by the majority.
