[L]iberty is not a set of laws or a system of government; it is not a nation or a species of patriotism. Liberty is a state of mind before it is anything else. You can have a nation of wealth and power, but without this state of mind—this psychological “America”—you are living in a deadening consciousness; with this state of mind, you can be in a darkened cell waiting for your torturer to arrive and yet inhabit a chainless space as wide as the sky.

“America,” too, is a state of mind. “Being an American” is a set of attitudes and actions, not a nationality or a posture of reflexive loyalty. This tribe of true “Americans” consists of people who have crossed a personal Rubicon of a specific kind and can no longer be satisfied with anything less than absolute liberty.
