“For, though the origin of most of our words is forgotten, each word was at first a stroke of genius, and obtained currency, because for the moment it symbolized the world to the first speaker and to the hearer. The etymologist finds the deadest word to have been once a brilliant picture.”
—Ralph Waldo Emerson (1803–1882)
“Art is good when it springs from necessity. This kind of origin is the guarantee of its value; there is no other.”
—Neal Cassady (1926–1968)
“Ice is an interesting subject for contemplation. They told me that they had some in the ice-houses at Fresh Pond five years old which was as good as ever. Why is it that a bucket of water soon becomes putrid, but frozen remains sweet forever? It is commonly said that this is the difference between the affections and the intellect.”
—Henry David Thoreau (1817–1862)
“Let Rome in Tiber melt and the wide arch
Of the ranged empire fall! Here is my space.
Kingdoms are clay; our dungy earth alike
Feeds beast as man. The nobleness of life

And such a twain can do ‘t, in which I bind,
On pain of punishment, the world to weet
We stand up peerless.”
—William Shakespeare (1564–1616)
