When I feel like going to the movies I go without having to ask the worlds permission. I have the liberty to go when ever I please to. If I decide to go to the movies by bus, or car, or train that is my choice and my liberty to decide how I get to my destination. If I want to go bowling instead of the movies that is my choice which is left up to me to decide and its not the worlds decision. Often a person considers themselves liberated which in turn means they are free and they do things on their own.
Liberties are like another word for freedom.
They basically have the same meaning. The world that we live in is based on freedom. Without freedom what is there left to live for if we can't even make our own choices for the future. Everyone has freedom whether they realize it or not. Freedom, what it means to me and you may be different but all in all it is what it is Freedom.
