Freedom.

"One of the greatest delusions in the world is the hope that the evils in this world are to be cured by legislation."
-- Thomas B. Reed

"Inequality will exist as long as liberty exists. It unavoidably results from that very liberty itself"
-- Alexander Hamilton

"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
-- Benjamin Franklin

"I would rather be exposed to the inconveniences attending too much liberty than to those attending too small a degree of it."
-- Thomas Jefferson

"There is only one basic human right, the right to do as you damn well please. And with it comes the only basic human duty, the duty to take the consequences."
-- P.J. O'Rourke

"It is not the business of government to make men virtuous or religious, or to preserve the fool from the consequences of his own folly. Government should be repressive no further than is necessary to secure liberty by protecting the equal rights of each from aggression on the part of others, and the moment governmental prohibitions extend beyond this line they are in danger of defeating the very ends they are intended to serve."
-- Henry George

"If a nation values anything more than freedom, it will lose its freedom; and the irony of it is that if it is comfort or money that it values more, it will lose that, too."
-- Somerset Maugham

When liberty is taken away by force it can be restored by force. When it is relinquished voluntarily by default it can never be recovered. -Dorothy Thompson
