Horace, Satires:
"Why do you laugh? Change but the name, and the story is yours."
Thoreau, Walden:
"Not till we are lost - in other words not till we have lost the world - do we begin to find ourselves, and realize where we are and the infinite extent of our relations."
Emerson, Self-Reliance:
“For nonconformity, the world whips you with its displeasure.”
