"Much Madness..."

    "Sometimes I ain't so sho who's got him a right to say a man is crazy and when he ain't. Sometimes I think there ain't none of us pure crazy and ain't none of us pure sane until the balance of us talks him that-a-way. It's like it ain't so much what a fellow does, but it's the way the majority of folks is looking at him when he does it."
                                                    From As I Lay Dying, by William Faulkner

Poem #435
by Emily Dickinson

Much Madness is divinest Sense--
To a discerning Eye--
Much Sense--the starkest Madness--
'Tis the Majority
In this, as All, prevail--
Assent--and you are sane--
Demur--you're straightway dangerous--
And handled with a Chain--

assent = say yes
demur = say no
discerning = showing good judgement
starkest = most obvious
divinest = most perfect
