THE RIGHT WORD
freedom, independence, liberty
The Fourth of July is the day on which Americans commemorate their nation's independence, a word that implies the ability to stand alone, without being sustained by anything else.
While independence is usually associated with countries or nations, freedom and liberty more often apply to people. But unlike freedom, which implies an absence of restraint or compulsion (: the freedom to speak openly), liberty implies the power to choose among alternatives rather than merely being unrestrained ( | the liberty to select their own form of government). Freedom can also apply to many different types of oppressive influences ( | freedom from interruption; freedom to leave the room at any time), while liberty often connotes deliverance or release ( | he gave the slaves their liberty).
Notice how the two definitions are very different except for in one instance; both include "the state of not being imprisoned or enslaved". Somewhere along the line, this convergence of definition allowed for a flip in the popular culture to occur, where simplistic freedom replaced the far more sinewed--and thus complicated--liberty in the public discourse. This is a tragedy.
Freedom and liberty are NOT the same thing. Freedom is devoid of responsibility ("nothing left to lose"?) and awareness for it's environment, people and society included...
"My freedom ends where yours begins"
This maxim speaks directly of the true nature of what it means to live in a group (which connotes a society, which connotes all sorts of things like laws and politics.) If "freedom ends", then it is not by definition freedom, for freedom has no limits. If I accept that there is a self and an other, and that we have met, then it is with liberty that we must live together. I am free to kill you, but living in a group it goes further than mere freedom, for I have the liberty to choose to do so and suffer the responsibility such an act entails.
