A poem by Emily Dickinson (1830–86):
The brain is wider than the sky,
For, put them side by side,
The one the other will include
With ease, and you beside.The brain is deeper than the sea,
For, hold them, blue to blue,
The one the other will absorb,
As sponges, buckets do.The brain is just the weight of God,
For, lift them, pound for pound,
And they will differ, if they do,
As syllable from sound.
From Complete Poems (1924).
Mind Hacks 
MUCH madness is divinest sense
To a discerning eye;
Much sense the starkest madness.
’T is the majority
In this, as all, prevails.
Assent, and you are sane;
Demur,—you ’re straightway dangerous,
And handled with a chain.
– Emily Dickinson
