[ame=http://en.wikipedia.org/wiki/Liberty]Liberty - Wikipedia, the free encyclopedia[/ame]The concept of negative liberty has several noteworthy aspects. First, negative liberty defines a realm or "zone" of freedom (in the "silence of law"). In Berlin's words, "liberty in the negative sense involves an answer to the question 'What is the area within which the subject -- a person or group of persons -- is or should be left to do or be what he is able to do or be, without interference by other persons."
I don't know how best to answer because the question is so broad. I suppose the simplest answer is that in most forms of democracy the people will decide with their votes. When government becomes overly intrusive, we will vote the ******** out.
