How to Lose a Country: Henry David Thoreau, the Politics of Nature and the Citizenship of Fear

Because this world is not given but made, because it needs to be remade better, but can also be remade much worse, and because each of us is part of all of that - both its victim and its author, and its moral victim in part of because of being its author, and so responsible for it even as it harms us - we cannot withdraw from it. But we can retreat, from time to time, to places where we can see more clearly, and the company of people - living and dead - who help us to see.
— Jedediah Purdy
