Liberty is defined as freedom from restraint or control. There are several types of liberty including natural liberty (freedom before organized political life), national liberty (independence of a state), civil liberty (freedom of individual action and thought), political liberty (participation in government), and economic liberty (right to earn a livelihood). Civil rights include physical rights, freedom of mind, practical activity, right to life, education, association, and other facilities. Economic rights encompass the right to work, adopt a profession, protection from exploitation, and unemployment insurance. The right to property is also considered a basic human right.
