Walt Whitman

“A morning-glory at my window satisfies me more than the metaphysics of books.”

“I no doubt deserved my enemies, but I don't believe I deserved my friends.”

“Now I see the secret of making the best persons, it is to grow in the open air and to eat and sleep with the earth.” 

“The dirtiest book of all is the expurgated book.”

“The future is no more uncertain than the present.”

“To have great poetry there must be great audiences, too.”
