Freedom is the sum of what one can accomplish. According to the Swiss Philosopher Jean-Jacques Rousseau, one has a certain set of freedoms granted by nature and defined by the actual physical capabilities of our bodies. He said that we should give up that natural freedom for a set of freedoms within society. While we do lose some of our liberty, like the right to drive on the sidewalk or kill and eat people, we gain the capacity to live in a lawful and just society. In trading one set of rights for another, we can improve our lives.
